Answer:

125/343

Step-by-step explanation:

This question asks for us to evaluate: (5/7)³

When a number has an exponent, the number gets multiplied by itself according to the amount of the exponent.

(5/7)³

- 5/7 x 5/7 x 5/7

= 25/49 x 5/7

= 125/343

Answer:

$2$

Step-by-step explanation:

Given:

$-2(1-4x)=3x+8$

Let's distribute the parenthesis

$-2+8x=3x+8$

Let's subtract $-3x$ from both sides

$-2+5x=8$

Let's add $2$ to both sides

$5x=10$

Now, let's divide both sides by $5$ to get $x$ alone

$x=2$

2nd eq. 4d+2p=8.50

multiply 1st eq by 2

6d+6p=18.00

multiply 2nd eq by 3
12d+6p=25.50
subtract
-6d=-7.50
d=1.25
3p=9.00-3d

3p=9-3.75

3p=5.25
p=1.75
price of a pretzel=$1.75

price of a drink = $1.25
