Answer:
Let x represent the smaller number and y represent the larger number
<u>For the first equation </u>
Four times a number added to 3 times a larger number is 31 is written as
4x + 3y = 31
Making y the subject we have
3y = - 4x + 31
Divide both sides by 3
That's
<u>For the second equation</u>
Seven subtracted from the larger number is equal to twice the smaller number is written as
y - 7 = 2x
Making y the subject
We have
<h3>y = 2x + 7</h3>
Hope this helps you
25(2) + 7(1) + 3x = 78....x represents the number of 3 point shots
50 + 7 + 3x = 78
57 + 3x = 78
3x = 78 - 57
3x = 21
x = 21/3
x = 7....so there were 7 three-point shots made
Answer:
2
Step-by-step explanation:
so for a cube all dimensions are the same so length, width, and height are all the same and 2x2x2=8
Step-by-step explanation:
-35 x - 625 = 21875 so positive
263 x 0 = 0 so zero
-21 x 451 = - 9471 so negative
-350 x 89 = - 31150 so negative
