Step-by-step explanation:

Ex. 4 (2n- 5) = 3n + 10

So since there is a number outside the parenthesis (which is in the first term) You have to distribute the number by multiply 4 to 2n and to -5.

(4*2n) (4*-5) = 6n - 20 (ALWAYS Carry the negative sign when you have a negative answer.)

Then, Do the addition/subtraction property which would be:

6n - 20 = 3n + 10

-3n +20  -3n + 20

3n = 30

/3      /3

n = 10

Hopefully this helps.

3 moon + 1 star = 29 1 moon +1 moon = 15 Find value of 1 moon​
Montano1993 [528]

Hi!

I can help you with joy!

3 moons+1 star equals 29.

All right.

Actually, there are a few numbers that can be hidden behind the moon:

3*8=24 + 1 star (5) = 29

But 1 moon + 1 moon equals 15.

So one moon equals 7.5.

every 5 1/2 cups of flour weighs 1 9/16 pounds. use a unit rate to show how u could determine if there are more than lee than 35
umka21 [38]
Okay. So to find the unit rate,divide pounds of flour by the number of cups. Turn the mixed numbers into improper fractions, which are 11/2 and 25/16. To divide fractions, keep the fraction the same, change the division symbol into multiplication, and flip the second fraction over. Then, multiply straight across. 11/2 * 16/25 is 176/50 or 3 13/25 in simplest form. To find out if there are more or less than 35 cups of flour in a 10-pound bag, you can round the number to the nearest whole number and multiply it by 10. For the exact unit rate, there are 3 13/25 cups of flour per 1 pound bag. Now, multiply that number by 10. Going back to improper fractions, 176/50 * 10/1 is 1,760/50 or 35 1/5 in simplest form. There are more than 35 cups of flour in a 10-pound bag of flour.
