So there’s 2 steps to this. First we subtract what was added on both sides. 10-4 : 13-4 and we get 6:9. This ratio is true, but is not in simplest form, since both numbers are divisible by 3. So after dividing both sides by 3, the answer in simplest form will be 2:3. The correct answer is 2:3
4.6 Is the answer I thinkkkkk
Answer:
A.
Step-by-step explanation:
The formula for circumference is:
We know that the circumference is 8π inches. So, substitute 8π for C:
Solve for r. Divide both sides by 2π. So:
Therefore, the radius is 4 inches.
Hence, our answer is A.
Answer:
The answer is D, 25
Step-by-step explanation:
m/20= 4/5 Cross mutiply, m x 4, 20 x 5
4m = 100 Isolate the variable by dividing 4 on both sides
m = 25

Answer:
36
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
Simplifying the radicals in the expression
= 
= 
× = 2
= 
= 
× = 4
Thus
4 + 7
= 4 × 2 + 7 × 4
= 8 + 28
= 36
