Answer:
x = -20
y = -62
Step-by-step explanation:
Suppose x and y two number and such that :
- their sum = -102
- and y is 62 less than x
Which means :
then
then
x + y = (y+62) + y = -102
then
2y + 62 = -102
then
2y = -164
then
y = -164/2 = -82
therefore
x = y + 62 = -82 + 62 = -20

Answer:
P = (18a+10b+13) cm
Step-by-step explanation:
Given that,
A triangle has the lengths of (10a+9) cm, (8a—3) cm and (10b+7) cm.
We need to find an expression that represents the perimeter of the triangle.
Perimeter = sum of all sides
P = (10a+9) + (8a-3) + (10b+7)
Taking like terms together,
P = (10a+8a)+10b+(9-3+7)
= 18a+10b+13
Hence, the epresssion for the perimeter is (18a+10b+13) cm.
