A glacier is a giant mass of rocks and ice that flows downhill like a river. a certain glacier moves at a rate of 22 inches a da

larisa [96]

<span>To find the total distance the glacier moves we must first set up the expression for rate: 22 inches/day. Next, we convert the inches into feet and we know that 12 in = 1 ft : 22 inches/day * 1 ft/12 in = 1.83 ft/day. Finally, we multiply the number of days in year (365) by the 1.83 ft/day to calculate the total distance moved: 365 days * 1.83 ft/day = 668 ft. The glacier moved 668 feet in one year.</span>

Jenna bought 5 reams of paper at the store for a total of $21 . The tax on her purchase was $1 . Write a equation and solve to f

ludmilkaskok [199]

Answer:

The equation needed is $\textrm{Cost of 1 ream of paper} = \frac{20}{5}$

The cost per ream of paper = $4

Step-by-step explanation:

Here, the cost of 5 reams of paper = $ 21

The tax on her purchase = $1

So, the actual cost of 5 reams of paper = Total Cost paid - Tax amount

= $ 21 - $ 1 = $20

So, the actual cost of 5 reams of the paper is $20.

Now, to find out the cost of 1 ream of paper:

$\textrm{Cost of 1 ream of paper} = \frac{\textrm{Total amount paid for 5 reams}}{\textrm{ 5}} \\= \frac{20}{5} = 4$

= $4

Hence, the cost of each ream of paper = $ 4.

If 8y - 8=24 find the value of 2y

Mariulka [41]

Answer:

2y =8

Step-by-step explanation:

$8y - 8 = 24$

First let's find the value of y

Collect like terms and simplify ;

$8y = 24 + 8 \\ 8y = 32$

Divide both sides of the equation by 8

$\frac{8y}{8} = \frac{32}{8}$

Simplify

$y = 4$

Substitute 4 for y into 2y

$2y \\ = 2(4) \\ = 4 \times 2 = 8$
