Answer 1

Answer: Given:
Bolt of fabric = 14 3/8 yards
length of fabric per skirt = 2 1/2 yards

Convert mixed fractions into improper fractions.

14 3/8 ⇒ (14*8)+3/8 = 115/8
2 1/2 ⇒ (2*2)+1/2 = 5/2

115/8 ÷ 5/2

115/8 * 2/5 = 115*2 / 8*5 = 230 / 40
230/40 = 5.75

5 whole skirt

5/2 * 5 = 25/2 length of fabric used to make 5 skirts.

115/8 - 25/2 = 115/8 - (25/2 * 4/4) = 115/8 - 100/8 = 15/8 length of excess fabric

15/8 = 1 7/8 yards of fabric will be left.

Answers

Answer:

The correct answer is first option (-5, 5)

Step-by-step explanation:

It is given that,

3x - 4y = -35 and 3x + 4y = 5

To find the solution

Let, 3x - 4y = -35 ------- (1)

3x + 4y = 5 --------(2)

Eq(1) + (2) ⇒

6x = -35 + 5 = -30

x = -30/6 = -5

ex(1) ⇒ 3x - 4y = -35

3 *-5 - 4y = -35

-15 - 4y = -35

4y = -15 + 35 = 20

y = 20/4 = 5

Therefore x = -5 and y = 5

The correct answer is first option (-5, 5)

Let the variable s represent the amount Trey saved before mowing lawns.

Trey earns s dollars. Then he earns an additional $40. So far, he earns (s+40).
Then this amount is doubled: 2(s+40)
At the end, he has $234. So the equation is
2(s+40) = 234
2s + 80 = 234
2s = 154
s = 77

An arithmetic approach (solving using addition) could have the equation as
(s+40) + (s+40) = 234
s + 40 + s + 40 = 234
2s = 154
s = 77

If y varies directly with x and x=21 and y=14, what is the constant of proportionality?

Answers

Y varies directly with x
y = kx

y=14
x=21

14 = 21k

$(14)/(21)$ = $(21k)/(21)$
21 and 21 cancels out

$(2)/(3)$ = k

The constant of this proportionality is $(2)/(3)$
