What is the solution to question number 33?

If the width of the garden is w, then the maximum area available is a square, giving you w² as the dimensions. So:
w²=-w²+28w
2w²=28w
w=14
The perimeter is 14 x 4, or 56 feet

Joey puts 25% of his allowance into savings each week. If last week he put 10$ in savings, what was his allowance last week?

GrogVix [38]

Answer:

$40

Step-by-step explanation:

25% is 1/4.

If 10 is 1/4 of the full amount, then you take 10 and multiply by 4 to get the full amount.

10 times 4 equals 40.

A system of equations consists of a line s of the equation y = x - 5 that is graphed in orange, and a line t that passes through

Zarrin [17]

ANSWER

$x = 4$

and

$y = - 1$

EXPLANATION

Line s has equation:

y=x-5

And line t has equation:

$y = - \frac{3}{4}x + 2$

We equate the two equations to get:

$x - 5 = - \frac{3}{4} x + 2$

Multiply through by 4

$4x - 20 = - \frac{3}{4} x \times 4 + 2 \times 4$

$4x - 20 = - 3 x + 8$

$4x + 3x = 8 + 20$

7x=28

$x = \frac{28}{7} = 4$

$y = 4 - 5 = - 1$
