Answer:

$150

Step-by-step explanation:

Hi,

We know that 160Ibs of steel costs $120. To find the cost of 1Ib of steel, we have to divide both 160Ibs and $120 by 160. Here's what I mean...

Total amount: 160Ibs

Divide by 160...

Total amount: 1Ib

Total cost: $120

Divide by 160...

Total cost: $.75

That means that each pound of steel costs $.75

Now, multiply by 200 to get the total cost if you buy 200Ibs of steel...

200 x .75 = 150

The total cost would be $150

Hope this helps :)

Answer:

Your answer is B, 150

Step-by-step explanation:

If we look at the chart it says 160 pounds of steel is 120, so for example if we start from 40 we will have 30, so every time we add 40 pounds 30$ are added, meaning that 160+40=200, 120+30= 150, Thus B or 150 is our answer.

6 points Emily’s family needs to rent a moving truck to move their belongings to a different house. The rental cost for Trucks-A

Alexxx [7]

Answer/Step-by-step explanation:

Equation to represent the daily rental cost for each type of truck can be written as follows:

Daily rental cost for Trucks-A-Lot = 42 + 0.72m

Daily rental cost for Move-in-Truckers = 70 + 0.12m

Where, m = Emily's mileage

To determine the number of miles for which the truck cost the same amount, set both equations equal to each other and solve for m.

$42 + 0.72m = 70 + 0.12m$

Collect like terms

$0.72m - 0.12m = 70 - 42$

$0.6m = 28$

Divide both sides by 0.6

$\frac{0.6m}{0.6} = \frac{28}{0.6}$

$m = 46.7$

At approximately 47 miles, both trucks would cost the same amount.

Check:

Daily rental cost for Trucks-A-Lot = 42 + 0.72m

Plug in the value of x = 47

= 42 + 0.72(47) = $75.84 ≈ $76

Daily rental cost for Move-in-Truckers = 70 + 0.12m

Plug in the value of x = 47

= 70 + 0.12(47) = $75.64 ≈ $76

Angle∠efg and angle∠gfh are a linear pair, mangle∠efgequals=55nplus+2020, and mangle∠gfhequals=33nplus+1616. what are mangle∠e

mylen [45]

A linear pair is a pair of angles that form a line. When added, they will equal 180.

< EFG + < GFH = 180
5n + 20 + 3n + 16 = 180
8n + 36 = 180
8n = 180 - 36
8n = 144
n = 144/8
n = 18

< EFG = 5n + 20.....5(18) + 20 = 110 <==
< GFH = 3n + 16.....3(18) + 16 = 70 <==
