4 0

Answer:

Nevan does not win

He scored 74 points

Step-by-step explanation:

First, find how many points he gets from 58 correct questions:

Multiply 1 3/4 by 58:

58(1.75)

= 101.5

Then, find how many points he loses from 22 incorrect questions:

Multiply -1 1/4 by 22:

22(-1.25)

= -27.5

Then, subtract 27.5 from 101.5 to find how many points he scored:

101.5 - 27.5

= 74

Since he needed 90 points to win, he did not win because he only got 74.

yuradex [85]

Answer:

Step-by-step explanation:

Considering the complete question attached in figure.

Consider

Hadley = x

Parker = y

Greenville = z

Distance between Greenville and Parker = yz = 29

Given that distance between Hadley and Greenville is 13 miles less than the distance between Parker and Greenville.

                                        xz = yz -13 --- (1)

Distance between hardley and greenville = xz  = ?

From (1)

                                         xz = 29 -13

                                         xz = 16 miles

So Alan is right that distance between Hadley and Greenville is 16 miles

Solve for r 5(r-10)=-51
Pie

Answer:

r=−1/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(r−10)=−51

(5)(r)+(5)(−10)=−51(Distribute)

5r+−50=−51

5r−50=−51

Step 2: Add 50 to both sides.

5r−50+50=−51+50

5r=−1Step 3: Divide both sides by 5.

5r/5=−1/5

r=−1/5
