Step-by-step explanation:
5-9(8 - 2x) < 2x - 115 solve for x
Answer:
x < -3
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
5 - 9(8 - 2x) < 2x - 115
Step 2: Distribute parenthesis
5 - 72 + 18x < 2x - 115
Step 3: Combine like terms
-67 + 18x < 2x - 115
Step 4: Add 67 on both sides
18x < 2x - 48
Step 5: Subtract 2x on both sides
16x < -48
Step 6: Divide both sides by 16
x < -3
And we have our answer!
Answer:
x<-3
Step-by-step explanation:
5−9(8−2x)<2x−115
Use the distributive property to multiply −9 by 8−2x.
5−72+18x<2x−115
Subtract 72 from 5 to get −67.
−67+18x<2x−115
Subtract 2x from both sides.
−67+18x−2x<−115
Combine 18x and −2x to get 16x.
−67+16x<−115
Add 67 to both sides.
16x<−115+67
Add −115 and 67 to get −48.
16x<−48
Divide both sides by 16. Since 16 is >0, the inequality direction remains the same.
x<-48/16
Divide −48 by 16
x<−3
Question 4 Find the value of a and YZ if Y is between X and Z.
XY = 3a - 4, YZ = 6a + 2, XZ = Sa + 22
a=?
YZ=?
Answer:
a = 6YZ = 38Step-by-step explanation:
The segment addition theorem tells you ...
XY +YZ = XZ
(3a -4) +(6a +2) = (5a +22)
4a = 24 . . . . . . . . add 2-5a and simplify
a = 6 . . . . . . . . . . divide by 4
Then the length of YZ is ...
YZ = 6a+2 = 6(6) +2
YZ = 38

What is the solution to this system of equations?
x + 3y - z = 6
4x - 2y + 2z= -10
6x + z= -12
(an explanation would be great because i barely understand how to do this)
Answer:
[tex]x=-3, y=5, z=6[/tex]
Step-by-step explanation:
1. Divide by 2 both sides in the second equation:
[tex]4x - 2y + 2z= -10[/tex] [tex]2x - y + z= -5[/tex]2. From the third equation find z in terms of x:
[tex]6x + z= -12[/tex] [tex]z= -6x-12[/tex]3. Add up the first and new second equations and find y in terms of x:
[tex](x+2x)+(3y-y)+(-z+z)=6+(-5)[/tex] [tex]3x+2y=1[/tex] [tex]2y=1-3x[/tex] [tex]y=0.5-1.5x[/tex]4. Put new alternatives instead of y and z in the first equation:
[tex]x+3(0.5-1.5x)-(-6x-12)=6[/tex] [tex]x+1.5-4.5x+6x+12=6[/tex] [tex]2.5x=-7.5[/tex] [tex]x=-3[/tex]5. Now we can easily find other two unknowns by using their equations by means of x:
[tex]y=0.5-1.5\times(-3)[/tex] [tex]y=0.5+4.5[/tex] [tex]y=5[/tex][tex]z=-6\times(-3)-12[/tex] [tex]z=18-12[/tex] [tex]z=6[/tex]Answer:
Step-by-step explanation:
2x + 6y - 2z = 12
12x - 6y + 6z = -30
14x + 4z = -18
6x + z = -12
14x + 4z = -18
-24x - 4z = 48
-10x = 30
x = -3
6(-3) + z = -12
-18 + z = -12
z = 6
-3 + 3y - 6 = 6
-9 + 3y = 6
3y = 15
y = 5
x = -3, y = 5, z = 6

What's 5(m−2)−10=6+2(1−m)
Answer: m=4
Step-by-step explanation:
5(m-2) - 10 = 6 + 2(1 - m) Apply the distributive property on both sides
5m -10 -10 = 6 + 2-2m Now combine like terms on both sides
5m -20 = 8- 2m Now add 2m to both sides
+2m +2m
7m - 20= 8 Add 20 to both sides
+20 +20
7m = 28 Divide both sides by 7
m = 4
A ship travels a distance of 200 nautical miles in 10 1/2 hours. how many knots did the ship average each hour? (One knot equals 1 nautical mile per hour) Provide explination please
Answer:
19.05 knots average per hour
Step-by-step explanation:
Distance traveled = 200 nautical miles
Time taken = [tex]10\frac{1}{2}[/tex] hours = [tex]\frac{10\times2+1}2=\frac{21}{2}[/tex] hours
To find:
How many knots did the ship average each hour ?
Solution:
Here, we are given the distance traveled and total time taken to travel the distance.
As per question statement, we have to find the average speed of the ship.
Formula for average speed is given as:
[tex]\text{Average Speed = }\dfrac{\text{Total Distance traveled}}{\text{Total Time Taken}}[/tex]
Putting the values in the formula:
[tex]\Rightarrow \text{Average Speed = }\dfrac{200}{\frac{21}{2}}\\\Rightarrow \text{Average Speed = }\dfrac{200\times 2}{21}\\\Rightarrow \text{Average Speed = }\dfrac{400}{21}\\\Rightarrow \text{\bold{Average Speed = 19.05 nautical miles per hour}}[/tex]
It is also given that 1 nautical mile per hours is equal to one know.
Therefore, the average speed can be written as:
19.05 knots average per hour

if some one bakes 150 cookies and eats 10% how many did she eat
Answer:
[tex] \boxed{ \bold{ \boxed{ \sf{15 \: cookies}}}}[/tex]
Step-by-step explanation:
Total cookies = 150
percentage of cookies that she ate = 10 %
To find : Number of cookies that she ate
[tex] \sf{10\% \: of \: 150}[/tex]
To convert percent into fraction, divide it by 100 and remove the % symbol.
⇒[tex] \sf{ \frac{10}{100} \times 150}[/tex]
⇒[tex] \sf{15 \: cookies}[/tex]
Thus, She ate 15 cookies.

A line passes through the points (2,3) and (6,y) with a slope of 2. What is the value of y?
Answer:
5
Step-by-step explanation:
The slope of a line is always rise over run.
We need to make the rise over run equivalent to 2 to find the value of y.
Looking at the x-coordinates, 2 and 6, we can see there is an increase in 4.
Now we ask: What number, times 2, will equal 4?
That is 2.
So we have to make the increase in the y coordinates 2.
If we have the original point 3, an increase in 2 is 5.
So y is 5.
Hope this helped!
Answer:
11 = y
Step-by-step explanation:
Using the slope formula
m = (y2-y1)/(x2-x1)
2 = (y-3)/(6-2)
2 = (y-3)/4
Multiply each side by 4
2*4 = y-3
8 = y-3
Add 3 to each side
8+3 = y-3+3
11 = y

Elizabeth wrote 3.3 - 0.21= 1.2 Is her answer reasonable? Explain why or why not. Choose the correct answer below and fill in the answer box to complete your choice. A. The estimate would be 0-0= nothing, so her answer is reasonable. B. The estimate would be 4-0= nothing, so her answer is not reasonable. C. The estimate would be 3-0= nothing, so her answer is not reasonable. D. The estimate would be 3-0= nothing, so her answer is reasonable.
Answer:
The estimate would be 3-0= nothing, so her answer is not reasonable.Step-by-step explanation:
Given the expression written by Elizabeth as 3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.
Converting 3.3 and 0.21 to fraction
3.3 = 33/10
0.21 = 21/100
Taking the difference of both fractions
[tex]= \dfrac{33}{10} -\dfrac{21}{100} \\\\= \dfrac{330-21}{100} \\\\= \dfrac{309}{100} \\\\= 3.09\\[/tex]
Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). This large difference makes Elizabeth answer unreasonable.
D.
The estimate would be 30
3, so her answer is not reasonable

x/11 = 13/11 please help
Answer:
[tex]x=13[/tex]
Step-by-step explanation:
So we have:
[tex]\frac{x}{11}=\frac{13}{11}[/tex]
To solve for x, multiply both sides by 11.
[tex](11)\frac{x}{11}=(11)\frac{13}{11}[/tex]
Both the left and the right cancel. Thus:
[tex]x=13[/tex]
Our answer is 13 :)
Answer:
Hey there!
x=13
The denominator is the same for both sides, so to make the equation equal, x has to be 13.

When a problem involves more than one unit for a characteristic (such as length), now can you tell which unit is more appropriate to report the answer in?
Answer:
For larger measurements, we use larger unit while for smaller measurement we use smaller unit.
Step-by-step explanation:
Normally, For larger distances we make use of larger units while for smaller distances we make use of smaller units.
For example, if we consider the distance travelled by a person in some days;
For 15000 units distance; We can represent this value as 15 Kilometers
For 800 units distance; Rather than using kilometers, it would be better to represent it in meters as 8 meters.
Also, For 70 units distance; Instead of kilometers or meters, 70 cm would be a better unit of representation.
Likewise, If we consider some 3 dimensional shapes holding some substances,
For 7000 units, best unit of weight representation would be 7 Kg
For 600 units, instead of in kg, best unit of weight representation would be 600 grams
For 50 units, best unit of weight representation would be 50 grams
So, looking at the examples given in both weight and distances, we will conclude that for larger measurements, we use larger unit while for smaller measurement we use smaller unit.
