The answer to question 34:
Let 'x' = pounds of gravel. The ratio of mulch to gravel is given 2 1/4 | 1 1/3. Which equals 9/4 | 4/3 = 27/16.
So the total gravel and much is equal to x + 27/16x = 172
Solving for 'x'
43/16 x = 172
x = 172 (16/43) = 64 pounds of gravel Mulch = 27/16x = 64 (27/16)= 108 pounds
The answer to question 35:
A.) 1,080 beats per minute at rest and 1,500 beats per minute while running.

Answer:
c=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(c+1)=10
(2)(c)+(2)(1)=10(Distribute)
2c+2=10
Step 2: Subtract 2 from both sides.
2c+2−2=10−2
2c=8
Step 3: Divide both sides by 2.
2c
2
=
8
2
c=4
