48y + 40x factored is 8(6y+5x)
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
Answer:
3x0.9, 30x9, 3/1000 times 9/10000
Step-by-step explanation:
Multiply each factor by multiples of ten.
10 minutes it will take you 10 minutes 10 minutes it will take you 10 minutes
Let the age of Jay be x years, so age of Jay's father is 2x years .
After 20 years,
Jay's age will be 
And Jay's father age will be 
But at that time, jay's age will be
So we have
Cross multiplication
Therefore Jay's age is 20 years and Jay's Father's age is 40 years .
