Distance between home and school(on map)=5cm
every 4cm=8km
therefore distance between home and school=
5/4×8 = 1.25×8 = 10km
P=3r + 2s you need to get all the numbers and variables on the other side of the equation so that s is alone.
P -3r = 2s Subtract the 3r from both sides.
P- 3r /2 =s now divide the whole amount P-3r by 2 and you've got your answer!
Its 6/7 (A) because the denominators are the same, so the denominator stays the same. But if it isnt I am sorry.
Answer:
6 pieces
Step-by-step explanation:
6x5=30
6x3=18
18-12=6
the total would be 31ft and 6 inches
Answer:
4 visits.
Step-by-step explanation:
First make an equation to represent the cost of the museum stuff using the formula y=mx+b
y=5x+11 would be the formula because you pay a flat fee of $11 for the membership and $5 for each visit after (x represents visits, y represents total cost)
Now we need to figure out how many visits a bill of $31 would represent.
We plug in 31 for y because y represents the total cost.
31=5x+11
Now solve for x.
Subtract 11 from both sides: 20=5x
Divide each side by 5: 4=x
Since x=4, it means that a bill of $31 would represent four visits.
