Answer:

<h2>d. 10a + 5b</h2>

Step-by-step explanation:

5(a + a + b) = 5(2a + b)

use the distributive property:

<em>a(b + c) = ab + ac</em>

<em />

= 5 · 2a + 5 · b =10a + 5b

Answer:

\boxed{\sf{D. \quad 10a+5b}}

Step-by-step explanation:

Use a distributive property.

<u>Distributive property:</u>

\Longrightarrow: \sf{A(B+C)=AB+AC}

<h3>⇒ 5(a+a+b)</h3>

⇒ a+a=2a

<u>Rewrite the problem down.</u>

\Longrightarrow: \sf{5(2a+b)}

<u>Multiply should be expanded.</u>

⇒ 5*2a=10a

⇒ 5*b=5b

<u>Rewrite the problem.</u>

<u>⇒ = 10a+5b</u>

  • <u>Therefore, the final answer is 10a+5b.</u>

I hope this helps you! Let me know if my answer is wrong or not.

Ghella [55]

Answer:

1 gamma = 15/8 alphas

Step-by-step explanation:

so we start by finding out what 1 gamma and 1 beta equals.

we know 4 gammas = 5 betas so if we divide by four on both sides we get:

1 gamma = 5/4 betas. we can apply that same procedure to 2 betas = 3 alphas and get 1 beta = 3/2 alphas

we know that 1 gamma = 5/4 betas and 1 beta = 3/2 alphas so how many alphas = 5/4 betas? using a proportion of ((3/2)/1) = ((x)/(5/4)) we can find that 5/4 betas = 15/8 alphas

therefore we know 1 gamma = 15/8 alphas or 1 and 7/8 alphas
