Answer:

<h2><em><u>m = 20</u></em></h2><h2><em><u>a = 48</u></em></h2><h2><em><u>These are the answers.</u></em></h2>

Step-by-step explanation:

1. m/-8 = -2.5

*-8 = *-8

m = -2.5*-8

m = 2.5*8

<em><u>m = 20</u></em>

2. 7/8a = 42

*8            *8

7a = 336

/7       /7

a = 336/7

<em><u>a = 48</u></em>

<em><u></u></em>

Hope this helped,

if she can fly from Washington DC to Ocean City MD 162 miles in 18 minutes how long would it take her to travel 486 miles???
o-na [289]
We can put it like this
162/18=486/x
cross multiply
162*x = 486 * 18
162*x = 8748
divide both sides by 162
x = 54

It will take her 54 minutes to travel 486 miles

Hope this helps :)

A lawn mower cost $470 when new and is expected to last 10 years. What will it be worth in 7.5 years? (Assume the lawn mower has
USPshnik [31]
Answer: 117.5
Explanation: Assuming that after 10 years the lawn mower would have a value of 0. We can evenly divide $470 by the amount of years.
$750/10 = $75
We would then multiply 75*7.5 years to then realize the value lost over that amount of time would be $352.5, subtracting that from the original value of $470 would then be 117.5

Kim orders catering from Midtown Dinerfor $35. She spends $5 on a large order of potato salad and the rest on turkey sandwich. E
aivan3 [116]

Answer:

Kim had bought 12 sandwiches.

Step-by-step explanation:

Given:

Amount spend at Midtown Dine = $35

Amount spend on large order of potato salad = $5

Cost of each sandwich = $2.5

We need to find the number of sandwich did Kim bought.

Solution:

Let the number of sandwich Kim bought be 'x'.

Now we know that;

Amount spend at Midtown Dine is equal to sum of Amount spend on large order of potato salad and number of sandwich Kim bought multiplied by Cost of each sandwich.

framing in equation form we get;

5+2.5x=35

Subtracting both side by 5 we get;

5+2.5x-5=35-5\\\\2.5x=30

Dividing both side by 2.5 we get;

\frac{2.5x}{2.5}=\frac{30}{2.5}\\\\x=12

Hence Kim had bought 12 sandwiches.
