Answer:
X = 10 + 4 Simplified: X = 14
Step-by-step explanation:
-1/5 (x - 4) = -2
distributive property
(-1/5 · x) + (-1/5 · -4) = -2
simplify
-1/5x + 0.8 = -2
multiply each side by -5
X + -4 = 10
simplify
X - 4 = 10

13.) (t⁻⁴)⁻⁹t² Now if the exponents outside of the parenthesis, that means you multiply them. t⁻⁴⁽⁻⁹⁾=t⁴⁵ Next, When it look like this: t⁴⁵ · t², don't multiply! When it comes to this, you had to add the exponents because it has the same base number: t⁴⁵⁺²=t⁴⁷.
Here's your answer to your question, t⁴⁷.
8:14 is ratio to red to all apples
8:6 is the ratio to green apples
Answer:
E. -8/3
F. 8/3
Step-by-step explanation:
9x^2-64=0
Add 64 to each side
9x^2-64+64 = 0+64
9x^2 =64
Divide each side by 9
9x^2/9 = 64/9
x^2 = 64/9
Take the square root of each side
sqrt(x^2) = ±sqrt(64/9)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
x = ±sqrt(64)/sqrt(9)
x = ± 8/3
