3 0

Answer:

B

Step-by-step explanation:

Start by writing the ratios equal to each other since they are equivalent.

\frac{21}{x}=\frac{7}{10}

Notice if you divide 21/3 = 7. Since they are equa then x/3=10. What number divided by 3 equals 10? x=30

4[( 8 + 4)10] + 24 devided by 2^3
Nikolay [14]
4[(8+4)10] + 24
so 8 + 4 is 12. Multiply that by 10 and that's 120.
120 + 24 is 144
144 × 4 is 576
for "devided by 2^3" do you mean divided by 2/3?
If so then its 576 ÷ 2/3 = 96
