Well Zack's cost more because, he paid $567.00 for whatever he bought, while Mal paid $245.00 for whatever he bought.
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
Divide the quantity done by the time:
2/3 / 3/4
When dividing by a fraction flip it over and change divide to multiply:
2/3 x 4/3 = (2 x4) / (3x 3) = 8/9
In 1 hour she will complete 8/9 of the project.
A good way to see what Shelby first did is to turn the amount she says she made into an improper fraction. You do this by multiplying the number to the left of the fraction by the denominator and adding it to the top. This shows Shelby divided 7 by 4 to get her 1 3/4 cups of juice answer. Since Shelby divided, a good option would be to try and multiply the original 7 amount by 4, as there is also 4 cups in a single quart, so 7 times 4. This number will be how many cups of juice she made.
