Question

The perimeter of an isosceles triangle is 112
inches. The area of the triangle is 588 square
inches.
a) Find x.
Answer in units of inches
b) Find y.
Answer in units of inches

Answer 1

wait, what is x and y?

Answer 2

it's number 9 on the pdf file

Answer 3

perimeter: 2y+x=112

Answer 4

area of trinalge= base x heightx 1/2

so 28(1/2)(x)=588
and you can simplify the equation so
14x=588
divide both sides by 14
x=42

substitute this value of x into any one of the orignal 2 equations to solve for y

Answer 5

so x= 42 y=35?

Answer 6

correct

Answer 7

can you help me with another problem in the pdf file?

Answer 8

sure. which one?

Answer 9

number 16

Answer 10

similar to the glove one
let d= hot dogs
b=burgers

Answer 11

d+b=8

Answer 12

d+b=8
1.6d+5b=19.6

Answer 13

to find d I will do 1.6(8-b)+5b=19.6?

Answer 14

no. this will get you to find b

but you can still keep going to find b and then plug it back to the equation to find d

Answer 15

d=6
b=2?

Answer 16

correct agian
