Answer:

30 dollars

Step-by-step explanation:

they give you the equation already of E(h) = 10h with h being hours. So, if she tutors for 3 hours then 10(3) would equal 30 dollars.

Answer:

30 dollars.

Step-by-step explanation:

Because it already gave you the expression:

E(h) = 10h

Since h represents the hours she worked, then simply replace h with 3, because she has worked 3 hours. Then solve.

E(h) = 10(3)

E(h) = 30

She makes 30 dollars if she tutors for 3 hours.

This question is the on I need help with
allsm [11]

let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.

likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.

197 - 122 = 75 oz

and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.

A house is listed for sale at $235,000, but the listing does not include square
Galina-37 [17]

Answer:

Option B.

Step-by-step explanation:

If the cost of the house (y) is in thousands and area of the house is x ft².

Cost of the house is modeled by the equation given,

y = 0.06x + 60.5

By substituting the values in the line of best fit,

235 = 0.06x + 60.5

0.06x = 235 - 60.5

0.06x = 174.5

x = \frac{174.5}{0.06}

x = 2908.33 ft²

x ≈ 2900 ft²

Therefore, Option B will be the correct answer.
