Answer:
19 weeks
Step-by-step explanation:
Given equation:
P = w
Where,
w = the number of weeks he has taken piano lessons
p = the total number of pieces he has learned
how many weeks of piano lessons will Lamar need before he will be able to play a total of 19 pieces?
Find w when p = 19
P = w
p = 19
Since P = w
19 = w
Therefore,
w = 19
Lamar need 19 weeks before he will be able to play a total of 19 pieces
Decimal - 1.6 fraction - 1 3/5
First you find the square root of 16, which is 4. Then multiply 4 by 20, which is 80. Therefore, your answer is 80.
its (a) because (a) is C(x)=3x4+30x and 9+21 is 30 so its 3x2+30
Answer:
Step-by-step explanation:
5/14=x/28
Cross multiply to get
14x=140
Divide both sides by 14
x=10
Or
See that 28 is 14*2 and multiply 5*2 to get the same answer
