Answer:

Variables are x, y, z

System of equations are;

2x + z = 49

31.49x + 9.75z = 625.61

Step-by-step explanation:

Let x represent uniforms, y represent volleyball, z represent a pair of knee pads.

We are told he bought 6 more balls than uniforms. Thus; y = x + 6

Since he is buying 55 items, thus equation that represents total number of items bought is;

x + y + z = 55

Since y = x + 6, then;

x + x + 6 + z = 55

2x + z = 49

We are told he purchased uniforms for $18.5 each, volleyball for $12.99 dollar each, knee pads for $9.75 dollar for each pair

Since he has a budget of $703.55.

Thus, equation that represents budget and amount for each item is;

18.5x + 12.99(x + 6) + 9.75z = 703.55

18.5x + 12.99x + 77.94 + 9.75z = 703.55

31.49x + 9.75z = 703.55 - 77.94

31.49x + 9.75z = 625.61

Margaret [11]

If two triangles are similar, then their side lengths are proportional.

RS / JK = RT / JL

5 / x = 4 / 7

4x = 35

x = 35/4 = 8.75

RT / JL = TS / LK

4 / 7 = 6 / (y + 2)

42 = 4(y + 2)

42 = 4y + 4

4y = 38

y = 38/4 = 9.5

LK = 9.5 + 2 = 11.5 cm

JK = x = 8.75

Hope this helps!
