Answer:
x + 2 = 8
Step-by-step explanation:
When you solve the other problems you get x=-6 for all of them except c. You need to take the number and subtract ( or if its negative add) it to the other side to get your answer for each one. Once this is done the solution to x is found

Maya started to run on a treadmill after setting its timer for 99 minutes. The display says that she has finished 27% of her run. How many minutes have gone by? Round your answer to the nearest tenth. minutes
Answer:
26.73 minutes have gone by
Step-by-step explanation:
Use cross multiplicationx 27
---- = ----- since we are trying to find how many minutes out of 99 passed,
99 100 place x for the missing digit
solvex times 100 = 99 times 27
simplifyx100 = 2673 x times 100 is just x100 since we don't know what x is, and 99
times 27 is 2673
figure for xx100 = 2673 to find x, it needs to be alone (x is very introverted :'> ) we can
---- ------- remove 100 by doing the opposite of what 100 is doing to the
100 100 x. Since it is 100 TIMES x, we will remove it by dividing 100 by
100 (which crosses it out) and then 2673 divided by 100. 2673
x = 26.73 divided by 100 gives us 26.73, so x equals 26.73.

Group of answer choices
No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.

Find the equation of a line that passes through the point (3,4) and has a gradient of 4.
Leave your answer in the form y= mx + c
HELP ASAP WIL LGIEV BRANLIEST FOR CORRECT ANSWER
Answer:
y=4x-8
Step-by-step explanation:
Y=mx+c
4=4(3)+c
C=-8
y=4x-8
Step-by-step explanation:
given that gradient i.e. m= dy/dx = 4.
equation passes through point (3,4)...
(Y - y1) = m (X-x1)
Y-4 = 4(X-3)
Y-4 = 4X-12
or Y = 4X-8
At the beginning of Jack's diet, he was 257 pounds. If he lost 3 pounds per week, find his weight after
12 weeks.
Answer:
A loss of weight means we subtract from Jack's current weight.
Step-by-step explanation:
A loss of weight means we subtract from Jack's current weight. New Weight = Current Weight - Weight Loss per week * number of weeksNew Weight =257 - 3*12New Weight =257 - 36New Weight = 221
b. Write the polynomial 3x2 + 4x -10+6x in standard form and also write its degree.
Answer:
Standard form → [tex]3x^{2} +10x-10[/tex]
Degree → 2
Step-by-step explanation:
GIven polynomial is
⇒[tex]3x^{2} +4x-10+6x[/tex]
Simplifying,
⇒[tex]3x^{2} +4x-10+6x\\\\3x^{2} +4x+6x-10\\\\3x^{2} +10x-10[/tex]
The standard form of the given polynomial is:
→[tex]3x^{2} +10x-10[/tex]
And the degree of this polynomial is 2 because the highest power of the terms is 2.
The terminal ray of ∠A passes through the point (−4,−6). ∠A is drawn in standard position. What is the value of cscA?
The terminal ray of an angle A passes through the origin
The value of csc(A) is -1.2
How to determine the cosine of angle AThe coordinates of the terminal ray is given as:
(x,y) = (-4,-6)
Start by calculating the length (L) of the hypotenuse
[tex]L = \sqrt{x^2 + y^2}[/tex]
So, we have:
[tex]L = \sqrt{(-4)^2 + (-6)^2}[/tex]
Evaluate the exponent
[tex]L = \sqrt{52}[/tex]
Evaluate the root
[tex]L = 7.2[/tex]
The sine of the angle A is then calculated as:
[tex]\sin(A) = \frac{-6}{7.2}[/tex]
The csc of the angle A is then calculated as:
[tex]\csc(A) = \frac{1}{\sin(A)}[/tex]
So, we have:
[tex]\csc(A) = \frac{7.2}{-6}[/tex]
[tex]\csc(A) = -1.2[/tex]
Hence, the value of csc(A) is -1.2

c) How many slices are left over? Pls explain! :)
I will give you 50 POINTS:D
Answer:
Hi im not sure but if I was doing this this is what i would say
Step-by-step explanation:
a) since the pizza is split in 6th then the pizza would be 6/6th
b) 7/4 is equal to 1 2/4 ( not 100% simplified ) but 1 2/4 also equals to 6/6ths because 1 2/4 = 4+2=6 (not the best accurate explanation )
c) no slices are left over if joan ate 7/4th of the pizza XD
