Answer:
He runs about 30 miles (29.75)
Step-by-step explanation:
4 miles per day for 7 days is 28 miles
(4+4+4+4+4+4+4)
add up the additional quarter mile per day for 7 days which is
(.25+.25+.25+.25= 1 mile, +.25 +.25 +.25= .75 mile)
add these miles to the 28
(1+28+.75)
Final answer=29.75
Answer:
x=4
Step-by-step explanation:
18 x 7ˣ = 2¹ x 3² x 7ˣ

x+1 = 5
x = 4

Hello!
Formula for the area of a triangle:
A = 1/2(bh)
We are given the height and area, so we can plug those into the formula to solve for b:
90 = 1/2(18b)
Multiply both sides by 2:
180 = 18b
Divide both sides by 18:
b = 10 inches.
Answer:
d
Step-by-step explanation:
the anwser is d
2x-5y =-5
14x+5y=-5
---------------
16x = -10
x = -10/16
x = -.626
2x-5y = -5
2(-.625) -5y = -5
-1.25 - 5y = -5
-5y = -3.75
y = .75
Choice A is approximately -.6 and .8 the others are not going to be close
