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.
Proportions is an what to 1 as in 1 seed to every pumpkin
Okay, so powers are multiplied out of parenthesis.
Every number of a variable has 1 power.
x^2 + 2^2
x^2+4
