The perimeter of MATH is 4w + 6 and the perimeter of GEOM is 6w - 8. the perimeters are the same so set them equal,
4w + 6 = 6w - 8... use inverse to get all like terms on opposite sides
-4w + 8 = -4w + 8
14 = 2w... divide both side by 2 to get w alone
÷2 = ÷2
7 = w
so B. 7 is the answer
Answer:3.50x+40=57.50
They bought 5 movies
Step-by-step explanation:
first what you have to do you have to find the common denominator which is 24
it's 24 because 8 times 3 equals 24 and 12 times 2 equals 24 so they have a like denominator so what you have to do to the bottom you have to do to the top so 8 times 3 is 24 so 3 times 3 is 9 so the new fraction is 9/24. Then 1/12 12×2=24 and 1×2= 2 so the new fraction is 2/24. that would leave you with the problem of 9/24 + 2/24 which is 11/ 24
Let’s first find the rate that she types at in wok.
128/3 = 42+2/3 words per minute.
Now divide 576 by the rate.
576/42.666= 13.5 minutes
