X = Leonard, y = Liam
x = y + 7
3x + 2y = 96
now we sub
3(y + 7) + 2y = 96
3y + 21 + 2y = 96
5y = 96 - 21
5y = 75
y = 15
x = y + 7
x = 15 + 7
x = 22
<span>Liam has 15 and Leonard has 22. </span>

Answer:
55mph
None of the option is correct
Step-by-step explanation:
Let v be the speed and t as the time taken. If speed varies inversely as the time it takes to drive, then v ∝ 1/t.
v = k/t where k is the constant of proportionality.
IF it takes Kris 5 hours when driving at 55 mph, then v = 55mph when t = 5 hours.
Substituting this values into the formula above;
55 = k/5
k = 55*5
k = 275mp/hr²
To calculate the speed it will Martin to drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t
v = 275/5
v = 55 mph
<em>Hence, martin will also need to drive at 55mph to take 5 hours</em>
Answer:
86.9 cm^3
Step-by-step explanation:
You have to find the area of every face. Since the opposite sides have the same area, you can find three areas and then multiply by 2.
2(5.3x2)=21.2
2(4.5x2)=18
2(4.5x5.3)=47.7
You then add the values together...
21.2+18+47.7=86.9
Answer: 4
Step-by-step explanation:
Formula:
logb(x) = y, if by = x
Input:
x = 256
b = 4
Solution:
y = log4 256
= log4 44
= 4 log4 4 = 4 x 1
log4 256 = 4
