X * 0.85 = 136
x = 136/0.85
x = 160

Answer:
y = 2x + 4
Step-by-step explanation:
First find 2 points on the line to determine slope.
(0, 4) and (2, 8)
Slope = 
y = 2x + b
b = y - intercept
b = 4
y = 2x + 4
5/6 of an hour is 50 min. So 50 times 3 equals 150 min for reading. 3/4 of an hour is 45 min. 45 times 2 equals 90 min for science. And 1/2 of an hour is 30 min. So 30 times 4 equals 120 mins for math. Add 150,90, and 120 min all together and you get 360 mins total. Divide 360 by 60, and you get 6 hours total that Michaela spent on reading, math, and science. Not 2 1/2.
Answer:
M= 1/2(x)+7
Step-by-step explanation:
Let M = Martha.
Let X = Number of Lucy's blocks.
Martha has half the amount as Lucy - 1/2(x)
Then 7 more than that - 1/2 (x) + 7
