Solving a Real-World Problem A kite has a width of 16 inches and a height of 18 inches. Jasmine made three kites like the one shown. How much total material did she use? The area of one kite is in2. The amount of material Jasmine needs for three kites is in2.

The material needed to make 1 kite is 144 square inches and for 3 kites she need 432 square inches of the material.

Step-by-step explanation:

Diagonals of the kite = 16 inches and 18 inches

Area of the kite = (16 x 18) /2

= 144 square inches

Area of 3 kites = 3 x 144

= 432 square inches.

The material needed to make 1 kite is 144 square inches and for 3 kites she need 432 square inches of the material.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
