Answer:
if you're simplifying, it should be = -1b - 6
Step-by-step explanation:
1. 4(1-2b) + 7b -10 solve the parenthesis
2. 4 <u>- 8b</u> <u>+ </u><u>7b</u> - 10 combine like(same) terms
3. <u>4</u> - 1b <u>- 10</u> same as 2.
4. -1b - 6
Answer:
The ratio of green apples to red apples is .
Step-by-step explanation:
Given,
Number of red apples = 21
Number of green apples = 18
We have to find out the ratio of green apples to red apples.
Solution,
For finding the ratio we have to divide the number of green apples to the number of red apples.
So, we can frame the above sentence as;
Ratio = number of green apples/number of red apples
Now substituting the values, we get;
Ratio= 18/21 = 6/7
Hence The ratio of green apples to red apples is . 6/7
Their answer is correct so you need explanation?
Answer:
120 ounces
Step-by-step explanation:
First find how many ft2 of lawn 1 once can seed.
To do this we simply divide 3000 by 50 ( because 50 ounces of grass seed can seed 3000 ft2 of lawn )
3000 / 50 = 60
So 1 ounce can seed 60ft2 of lawn
To find how many ounces would be needed to seed 7200 ft2 of lawn we would divide 7200 by the amount of lawn 1 once can seed ( which is 60ft2 )
7200/60 = 120
So 120 ounces of grass seed would be needed to seed 7200 ft2 of lawn
It's 12 because if you divide 36 by 3 (consecutive) it equals 12
