35-7 which would equal 28, but that answer wouldn't be exactly correct, as this isn't in correct formation. An equation would be 2x + 7 = 35.
35-7= 28 divided by 2(2x) would equal 14
So Mary is 14 and her sister is 21.
21 + 14 equals 35
Answer: y = 9
Step-by-step explanation:
Since two points are given , we will use the formula for finding the equation in two points form , which is
=
= 1
= -3
= -9
= -9
Substituting into the formula , we have
=
=
=
= 0
y + 9 = 0
y = 9
Answer:
Step-by-step explanation:
The length can be found by setting up a proportion. If the width is reduced by some ratio, then the length will share the same ratio.
3 / 8 = x / 10 Multiply both sides by 10.
3 * 10 / 8 = x Multiply first
30/8 = x Divide next. You don't need to do it in this order.
3 6/8 Simplify
3 3/4 Give another choice
3.75
The length = 3.75 inches
If none of these are correct, please leave a note with your choices.
