Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
Change the common denominator so 3/4 ---> 9/12
3/4 and 9/12 are equal
Hope this helps!!!
A^2=B^2+c^2
8^2+15^2=X^2
so 289=X^2
the square root or 289 is 17, so the answer is 17ft
Wouldn’t it just be a and b
Answer:
35
Step-by-step explanation:
Here we see 5 black keys for every 7 white keys.
So the ratio is 5:7
If we need 49 white keys, find the amount we scale the original ratio by:
49/7 = 7
So we are scaling by a factor of 7.
The number of black keys would be 5 * the scale of 7. = 35
So there should be 35 black keys.
