Answer:
144 miles
Step-by-step explanation:
The scale of map B is (3.4 cm)/(6.8 cm) = 1/2 that of map A. Then the distance (d) between the cities is ...
(1.8 cm)/d = (1/2)·(1 cm)/(40 mi)
Multiplying by d·80 mi, we get ...
144 mi·cm = d cm
Dividing by cm, we have ...
144 mi = d
The distance from Gladville to Columbus is 144 miles.
I know that because my 8th grade math teacher taught us (in 1954)
that when you see the word "of" in a math problem, it almost always
means "times". So part of your question says "... finding a fractional
part times a whole number ...".
Answer:
465.3 = 16.5x
Step-by-step explanation:
We can determine the miles per gallon by taking the number of miles driven and dividing by the gallons
465.3 /16.5 =x
Rewriting by multiplying each side by 16.5
465.3 = 16.5x
Answer:
20, -20
Step-by-step explanation:
I assume you mean |x| + 31 = 51?
that means |x| + 31 - 31 = 51 - 31
==> |x| = 20
because this is absolute value
so x = 20 or -20
Answer:
2304
Step-by-step explanation:(this is how I do it so sorry if people do it a different way.) so that it's easier for me I like to double the prism so it makes a square. then you take the length and with and multiply them together. that multiply what you just got by the width "length at the top". then divide your answer by 2.
