Answer:
D is the correct one
Step-by-step explanation:
The whole angle equals 72 and the partial angle equals 45
You put
72-45= 27
So 3x=27
Then you solve this equation
3x = 27
x = 27/3
x = 9

Answer:
Mom === 10.25
Daughter === 3.25
Step-by-step explanation:
Let’s the mom age be 7+x and the daughters age be x. Put it in a linear equation 7+x=5(4+x).
open the bracket which will give you 7+x=20+5x.
collect like terms which will give you 5x-x=20–7 and you will get 4x=13 where x is 3.25 the mom is 10.25 and the daughters age is 3.25
7u^3 - u^2 - 7 + 2u^3 - 4u^2
(7+2)u^3 -(1+4)u^2 - 7
9u^3 - 5u^2 - 7
The correct answer is option A. Since store A is giving a discount of 15% on the original price i.e.$ p. Then, the price after discount will be equal to $ 0.85p . And, the second store B offers $150 less than the original price p i.e the price after reduction is $p-$150. Since both the proces after reduction are equal. Thus, $ 0.85p = $p-$150
