Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items wit

weeeeeb [17]

Answer:

$Change = \$8.82$

Step-by-step explanation:

Given

$Basketball = \$25.57$

$Air\ Pump = \$15.61$

$Amount = \$50$

Required

Determine the change received

First, we need to calculate the total amount spent

$Total = \$25.57 + \$15.61$

$Total = \$41.18$

This implies that Natalie pays a total of $41.18

Next, we calculate the change as thus:

$Change = Amount - Total$

$Change = \$50 - \$41.18$

$Change = \$8.82$

<em>Hence, the change is $8.82</em>

Solve for w. 9w-4/4=5w-6/7+6

ELEN [110]

Answer:

$w=\frac{1}{16}$

Step-by-step explanation:

$\frac{9w-4}{4} =\frac{5w-6}{7+6}$

$9w-1=\frac{5w-6}{13}$

$9w-1+1=\frac{5w-6}{13}+1$

$9w=\frac{5w-6}{13}+1$ <u />

13 × 9w = 13 × $\frac{5w-6}{13}+1$

117w = 5w - 6 + 13

117w = 5w + 7

117w - 5w = 5w - 5w + 7

112w = 7

112w ÷ 112 = 7 ÷ 112

$w=\frac{1}{16}$

16 - 2r = -3r + 6r +1

Alona [7]

Answer:

r=3

Step-by-step explanation:

Simplify the expression

16-2r=3r+1

isolate r by adding 2r to both sides

16=5r+1

isolate the numbers by subtracting 1 from both sides

15=5r

divide both sides by 5 to completely isolate r

r=3
