Step-by-step explanation:
it’s the third one
Answer:
13
Step-by-step explanation:
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
44% = 44/100 = 44 ÷ 100 = 0.44.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 44% of its value.
Percentage decrease = 44% × 13
New value = 13 - Percentage decrease
89.5%
This is because you move the decimal place by two places to the right whenever converting to a percentage.
Hope this helps!
Answer:
p = 5 and b = 8
Step-by-step explanation:
First, create a system of equations:
2p + 4b = 42
7p + 9b = 107
Solve by elimination by multiplying the top equation by -7 and the bottom equation by 2:
-14p - 28b = -294
14p + 18b = 214
Add these together, and solve for b:
-10b = -80
b = 8
Plug in 8 as b into one of the equations, and solve for p:
2p + 4b = 42
2p + 4(8) = 42
2p + 32 = 42
2p = 10
p = 5
So, p = 5 and b = 8
