7.D is the correct answer. I simplified 12/27 to 4/9 then i try to see if 4/9 is equivalent to 20/45 and it is you multiply 4 and 9 by 5= 20/45
8. 1.4*2.1=2.94 then 2.94/1.5= 1.96 so c=1.96
9. Explanation You multiply- 5/8 * 3/5 then divide = answer divided by 2/3
Solving: 5/8*3/5= 3/8 then 3/8 divided by 2/3, flip second number and then switch the division sign to multiplication sign so it should be like this : 3/8 * 3/2= 9/16
answer= 9/16
Answer:
no solutions
Step-by-step explanation:
8 + 10 - 6k = 6(4 - k)
Distribute
8 + 10 - 6k = 24 -6k
Combine like terms
18 -6k = 24 -6k
Add 6k to each side
18 - 6k +6k = 24 - 6k+6k
18 = 24
This is never true so there are no solutions
Step-by-step explanation:
Answer:
≈33.3%
Step-by-step explanation:
First we find the difference of the heights to see what the growth was
24-18 = 6
Then we find what percent 6 is of 18 to see what percentage growth occured
6/18 ≈33.3%
Answer:
54°
Step-by-step explanation:
Your triangle is isosceles. You have been given the third angle, and you have been asked to find the measure of one of the two equal angles. We know that the internal angles of a triangle sum to 180, so
