H=henry's age
j=julia's age
r=rhianna's age
h is 3 times of j
h=3j
r is 1/2 times of j
r=(1/2)j or
2r=j
so
h=3j
2r=j
sub 2r for j
h=3(2r)
h=6r
henry's age is 6 times of rhianna's age
Answer:
I'm assuming the 2 after 9t and -2t means squared.
7t² + 12t + 4
Step-by-step explanation:
To simplify the expression we should combine like terms. Like terms are terms with same variables and powers.
Let's start with 9t² and -2t² since they have the same variable and power of t². To combine them we should add them together which would be: 9t² + (-2t²) = 9t² - 2t² = 7t²
Next we can combine 7t and 5t since they have the same variable and power of t. 7t + 5t = 12t
4 doesn't have any like terms so we leave it as it is.
Lastly we add all of our terms: 7t² + 12t + 4

Answer:
Step-by-step explanation:
-x+4y=16
-x=16-4y
x=(16/-1)-(4y/-1)
x=-16+4y
