Answer:
x = 5
Step-by-step explanation:
1 - 2x - 1 = -10
- 1 - 1
-2x -1 = -11
+1 +1
-2x = -10
/-2 /-2
x = 5
Answer:
B.) x=5
Step-by-step explanation:
move 1 and -1 to the other side with -10 and change signs
-2x=-10+1-1 -> +1-1=0
-2x=-10
+2x=+10 divide both sides by 2
2x/2=10/2

Answer:
11/10 or 1 1/10 square feet
Step-by-step explanation:
Simplify the following:
((2 + 3/4)×2)/5
Hint: | Express ((2 + 3/4)×2)/5 as a single fraction.
((2 + 3/4)×2)/5 = ((2 + 3/4)×2)/5:
((2 + 3/4)×2)/5
Hint: | Put the fractions in 2 + 3/4 over a common denominator.
Put 2 + 3/4 over the common denominator 4. 2 + 3/4 = (4×2)/4 + 3/4:
(((4×2)/4 + 3/4) 2)/5
Hint: | Multiply 4 and 2 together.
4×2 = 8:
((8/4 + 3/4)×2)/5
Hint: | Add the fractions over a common denominator to a single fraction.
8/4 + 3/4 = (8 + 3)/4:
(((8 + 3)/4)×2)/5
Hint: | Evaluate 8 + 3.
8 + 3 = 11:
(11/4×2)/5
Hint: | Express 11/4×2 as a single fraction.
11/4×2 = (11×2)/4:
((11×2)/4)/5
Hint: | Express ((11×2)/4)/5 as a single fraction.

9. Given the circle below, find OR.
Answer:
A. 17
Step-by-step explanation:
Let X be the intersection of lines QR and NP.
By Power of a Point, we have [tex]QX\cdot XR=NX\cdot XP.[/tex]
(This can be proven with similar triangles by connecting QN and PR and using proportions with similar triangles [tex]\triangle QXN[/tex] and [tex]\triangle RXP[/tex].)
Plugging the values we know into [tex]QX\cdot XR=NX\cdot XP,[/tex] we have
[tex]12\cdot(x-2)=(3x-1)\cdot 3[/tex].
Dividing both sides by 3 gives
[tex]4(x-2)=3x-1.[/tex]
Distributing the left hand side gives
[tex]4x-8=3x-1.[/tex]
Subtracting 3x from both sides, we have
[tex]x-8=-1.[/tex]
Finally, adding 8 to both sides, we have
[tex]x=7.[/tex]
The question asks to find QR. (I'm assuming this is what you meant in the question.) With the lengths given, we know
[tex]QR=12+(x-2)=x+10.[/tex]
Therefore, plugging x in gives us
[tex]\boxed{QR=17.}[/tex]

The function a(n) = 3(2)^n represents the value of the nth term in a sequence. What is the sum of the 1st and 4th terms of the sequence
Answer:
54
Step-by-step explanation:
We are given the sequence or function:—
[tex]\displaystyle \large{a(n) = 3(2)^n}[/tex]
To find the sum of 1st term and 4th term, first we must find the first term and the fourth term which can be done by substituting n = 1 and n = 4.
[tex]\displaystyle \large{a(1)=3(2)^1}\\\displaystyle \large{a(1)=3 \cdot 2}\\\displaystyle \large{a(1)=6}[/tex]
Then when n = 4.
[tex]\displaystyle \large{a(4) = 3(2)^4}\\\displaystyle \large{a(4) = 3 \cdot 16}\\\displaystyle \large{a(4) = 48}[/tex]
Therefore, the sum of 1st term and 4th term is:—
[tex]\displaystyle \large{a(1)+a(4) = 6+48}\\\displaystyle \large{a(1)+a(4)=54}[/tex]

Answer: x = 62.5 degrees
Step-by-step explanation:
Angle DEC is adjacent to the angle measuring 137 degrees, which means their sum is 180 degrees. Therefore:
Angle DEC + 137 = 180
We can subtract 137 from both sides:
Angle DEC = 43 degrees
We know that the sum of the angles in a triangle is 180 degrees, so we can set up an equation for triangle DEC.
We know Angle D + Angle C + Angle E = 180, so we can plug in the values given for each.
Therefore, x + 5 + x + 7 + 43 = 180
We can combine like terms:
2x + 55 = 180
Subtract 55 from both sides:
2x = 125
Divide both sides by 2:
x = 62.5 degrees
The value of x if (5/7) * x = 10/7 so x =
Answer:
x = 2
Step-by-step explanation:
( 5 / 7 ) * x = ( 10 / 7 )
( 5 * x ) / 7 = ( 10 / 7 )
( 5 * x ) = ( 10 / 7 ) * 7
= ( 10 * 7 ) / 7
( 5 * x ) = 10
x = 10 / 5

The length of Celia 's garden is 15m 24cm. The length of her friend's garden is 2m 98cm more than Ceila 's. What is the length of her friend's garden
Step-by-step explanation:
so, that means the friend's garden length is
15m 24cm + 2m 98cm
we can do this in 2 main ways.
1. using the fact that this is a metric system with 1m = 100cm.
15.24m + 2.98m = 18.22m = 18m 22cm
2. using fractions
15 24/100 m + 2 98/100 m =
= (1500 + 24)/100 + (200 + 98)/100 =
= 1524/100 + 298/100 = (1524 + 298)/100 =
= 1822/100 = (1800 + 22)/100 = 18 22/100 m =
= 18m 22cm
ultimately, they are both really using the same principles, but it looks a little bit different.

y=6x+1
y+mx+3
Answer:
m = 6
Step-by-step explanation:
If the system of equations has no solutions, then the lines are parallel.
Parallel lines have the same slope.
The slope-intercept form of a linear equation is y = mx + b
(where m is the slope and b is the y-intercept)
Therefore, the slope of the equation y = 6x + 1 is 6
So the second equation should also have a slope of 6: y = 6x + 3
Now compare both
mx=6xm=6Hence m=6

An element with mass 820 grams decays by 26. 8% per minute. How much of the element is remaining after 18 minutes, to the nearest 10th of a gram?.
The element is remaining after 18 minutes with the rate of decaying of 26.8 % is 2.99 grams.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
An element with a mass of 820 grams decays by 26. 8% per minute.
Then the mass remaining after one minute will be
Remaining = 100 - 26.8
Remaining = 73.2 %
The element is remaining after 18 minutes will be
Mass = 820 × (0.732)¹⁸
Mass = 820 × 0.00364
Mass = 2.985
Mass ≈ 2.99
The element is remaining after 18 minutes is 2.99 grams.
