it's 270! the formula for triangles is base times height divided by 2, the measurement on the side means nothing in context of finding area
If she cut off nine pieces of 2-inch ribbon, in all, that would be 18. After that, it would simply be the matter of subtracting 24 and 18.
24 - 18 = 6.
And there's your answer. Liz has 6 inches of ribbon left.
multiply the number of ounces by the price per ounce
Blue jelly beans cost 0.28 per ounce and there are 4 ounces
4 * 0.28 = 1.12
red jelly beans cost 0.55 per ounce and there is 3 ounces
3 *0.55 = 1.65
now add the totals: 1.12 +1.65 = 2.77
this is more than the total they want of 2.20
so it is not reasonable.
4(y-3) = 4*y -4*3
= 4y - 12
Answer:
x = 3
y = 18
Step-by-step explanation:
you replace y with 6x
x + 6x = 21
combine like terms
7x = 21
divide both sides by seven
x = 3
then you plyg 3 into the other equation
y = 6(3)
y= 18
