Solution: (2,8)
Using the elimination method set up the system of equations like:
y = x + 6
y = 3x + 2
Eliminate the x-variable by multiplying the top equation by -3
-3y = -3x -18
y = 3x + 2
Combine terms:
-2y = -16
-y = -8
y = 8
Plug in 8 to one of the first equations for y
8 = 3x + 2
6 = 3x
x = 2
Solution: (2,8)
Answer:
18
Step-by-step explanation:
1,017.36 is the area of the circle and you need to find the radius
area formula : 3.14rsquared
so the formula you are going to solve for your answer is 3.14rsquared=1,017.36
divide by 3.14
rsquared = 324
un square it to get you radius which is 18
you didnt clarify whether you wanted radisu or diameter so ill give both
R: 18
D:36
5/14 is the answer. I'll do my best bud
Answer↑
Steps↓
Convert 2 1/2 to an improper fraction:
2 + 2+ 1 over 2
Once you add the numbers, that will be 5/2.
Now, multiply that with 1/7:
5/2 • 1/7
Your answer will be 5/14
Therefore, Rock A weighs 5/14 pounds
I believe that the answer is 14 or 7
Answer:
Boys: 75%
Girls: 25%
Step-by-step explanation:
Total: 28 Students: 100%
7 Girls in clas
28(total)-7 (girls)= 21 Boys in class
__________________
If we divide the amount boys OR girls ( depending on which gender) after the toal and move the decimal to the right twice after dividing) we will get our answer.
Formula:
(Amount of Boy or girls) = x
X/28
So since we are trying to get the percentages of boys, we will replace X with the amount of boys
21/28 = .75 ( then move the decimal to the right TWICE) = 75
Then you should get your percentages: 75% Also if your lookings for girls percentages, you basically subtract 75 ( boys percentages) with the total percentages ( 100) then you should get your answer for the girls: 25%
