If that is saying 390m tall, cm is a unit of meters, KHDMDCM, so the building is 39,000cm tall. Divide 39,000cm by 30cm, you end up with 1,300 feet. The answer is 1,300 feet

If x2 = 10, what is the value of x?

JulsSmile [24]

If you mean x^2 then there would be no answer after all, 3^2= 9 and 4^2= 16 so

If you mean 2x then the answer would be 5

Hope I helped?

Find: (4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) Place the correct coefficients in the difference.

DanielleElmas [232]

Answer: Our required answer will be

$11x^2y^3-4xy^2$

Step-by-step explanation:

Since we have given that

$(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)$

We need to get the difference:

1) We first open the second bracket and make appropriate change in signs :

$4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y$

2) Gather the like terms together :

$4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2$

Hence, our required answer will be

$11x^2y^3-4xy^2$

Every 5 1/2 cups of flour weighs 1 9/16 pounds. use a unit rate to show how you could determine if there are more than or less t

slega [8]

So 5 and 1/2 cup flour =1 and 9/16
multiply both sides by 16
80 and 16/2 cups=16 and 9
88 cups=25 pounds
divide by 5
88/5=5 pounds
multiply by 2
176/5=10 pounds
176/5=35 and 1/5
35 and 1/5 cups=10 pounds

there is MORE than 35 cups of flour in a 10 pound bag
