Answer:
21:8
Step-by-step explanation:
<u>Given information:</u>
Lori (x) is 8 years old.
In 5 years (x + 5), Philip will be twice Lori's age (y + 5 = 2(x + 5))
<u>The missing value, y, is needed to find the ratio for Lori's and Philip's ages in the present. To find y, solve this equation:</u>
y + 5 = 2(x + 5) First, distribute the 2 into x + 5.
y + 5 = 2x + 10 Next, isolate the variable y by subtracting 5 from both sides.
y = 2x + 5 After that, add in the value of x, 8.
y = 2(8) + 5 Finally, simplify the right side to find Philip's age.
y = 16 + 5
y = 21
<u>Now for the easiest part: The ratio of Philip's age now to Lori's age now.</u>
because 21 is not divisible by any of 8's factors, the current ratio of 21:8 cannot be simplified further.
So, the ratio is 21:8
Answer:
y^7
Step-by-step explanation:
y^3 . y^5 . y^-2 . y
= y^3 . y^5 . y^-2 . y^1
= y^( 3 + 5 - 2 + 1 )
= y^( 3 + 5 + 1 - 2 )
= y^( 9 - 2 )
= y^7
The first one is C. 68. The second one is B. 7. The third one is x = 21. The fourth one is CD = 10
A bag is exactly 3 3/4 pounds, it can be estimated at 4 pounds.
If Elisa, Luis, and Dwayne purchased 5 bags together, they will have an estimate of 20 pounds of bird seeds.
5 bags * 4 pounds/bag = 20 pounds
I think the answer is 15 and Put an number 0 150
