0.42z = 2.52
z = 2.52 / 0.42
z = 6
same as
z + 7.45 = 13.45
z = 13.45 - 7.45
z = 6
answer is top right z + 7.45 = 13.45
1) subtract 42.5 miles from 68 miles to find the gross change in distance: It is 25.5. Since this is a decrease, write -25.5 miles.
2) divide -25.5 miles by the original distance, 68 miles:
-0.375
3) multiply this by 100% to find the percentage decrease:
-37.5% (answer)
Answer:
y = 4x - 9
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"
The slope we can do rise over run "r/r" ot "y/x"
r/r = 4/1 = 4
The line is positive since its going up
y = 4x - 9
Hope this helped!

Answer:
Step-by-step explanation:
1) 2 - (- 8) = 2 + 8 = 10
2) 2/5 + (- 1/5) = 2/5 - 1/5 = 1/5
3) We can find the common denominators through the least common multiple between the denominators:
4,12 | 2
2, 6 | 2
1, 3 | 3
1, 1 (2 × 2 × 3 = 12)
Then, 12 is the least common denominator.
4) 8 (1/4) + 10 (2/5) + 7 (5/8)
8 (1/4) = 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 1/4 = 33/4
10 (2/5) = 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 2/5 = 52/5
7 (5/8) = 8/8 + 8/8 + 8/8 + 8/8 + 8/8
+ 8/8 + 8/8 + 5/8 = 61/8
33/4 + 52/5 + 61/8
Employing the least common denominator:
4, 5, 8 | 2
2, 5, 4 | 2
1, 5, 2 | 2
1, 5, 1 | 5
1, 1, 1 (2 × 2 × 2 × 5 = 40)
(40 ÷ 4 × 33)/40 + (40 ÷ 5 × 52)/40 + (40 ÷ 8 × 61)/40
330/40 + 416/40 + 305/40
1051/40
This person ran about 26 Miles
I hope I helped you.
