Answer:
Step-by-step explanation:
Let m = maracas
c = claves
d = djembe drums
12m + 6c + xd = $326
<ABC + <CBD = <ABD
substitute <ABD = 85 and <CBD = x
<ABC + x = 85
3x + 14 = 143
3x = 129
X = 43
Question:
Expand and simplify 5(x - 1) - 3(x + 4)
Answer:
1.) Use the distributive property to solve this equation:
5(x - 1) = 5x - 5
3(x + 4) = 3x + 12
2.) Put it in the equation:
5x - 5 - 3x + 12
3.) Group them:
5x - 3x - 5 + 12
4.) Simplify:
2x - 7
which is the answer.
Hope this helped! :))
