Answer:
True
Step-by-step explanation:
Let's solve your equation step-by-step.
m−38=15
Step 1: Add 38 to both sides.
m−38+38=15+38
m=53
Answer:
m=53
Answer:
At a combined speed of 6 in/min, it takes us 24 mins to clean the wall
Step-by-step explanation:
Since the question did not provide the speed with which each student cleans, we can make assumptions. This is so that we can solve the question before us
Assuming student 1 cleans at a speed of 2 inches per minute, student 2 cleans at a speed of 2½ inches per minute & student 3 cleans at a speed of 1½ inches per minute.
Let's list the parameters we have:
Height of wall (h) = 12 ft, Speed (student 1) = 2 in/min, Speed (student 2) = 2½ in/min, Speed (student 3) = 1½ in/min
Speed of cleaning wall = Height of wall ÷ Time to clean wall
Time to clean wall (t) = Height of wall ÷ Speed of cleaning wall
since students 1, 2 and 3 are working together, we will add their speed together; v = (2 + 2½ + 1½) = 6 in/min
1 ft = 12 in
Time (t) = h ÷ v = (12 * 12) ÷ 6 = 144 ÷ 6
Time (t) = 24 mins
The fixed fee is $5.75. This part of the equation is called the constant. There are no variable being multiplied or divided meaning it is not being grouped in any way. This tells us it stands alone and represents a number that is non -changing or fixed.
Simplify the exponents
3-2=1 therefore it should be 1/7 the third answer. Hope that helps
