Answer:
5x - 4
Step-by-step explanation:
2x + 3x = 5x
4 = 4
Let julia's age be x
Let Kara's age be 4x
x+4x=13
5x=13
x=13/5
2.6 years
The answer to this question is the second choice
hope this helps:)
<span>the probability that the average mileage of the fleet us between 27.2 and 28.8 will be:
27.2<x<28.8
this will be:
P(x<28.8)-P(x<27.2)
To evaluate this we use the z-score formula:
P(x<28.2)=P(z<Z)
Z=(x-</span>μ)/σ
μ-mean
σ-standard deviation
thus
z=(28.2-28)/5=0.04
thus
P(x<28.2)=0.5160
p(x<27.2
z=(27.2-8)/5=-0.16
P(z<-0.16)=0.4364
thus
P(x<28.8)-P(x<27.2)=0.5160-0.4364=0.0796
Answer: 0.0796
Answer:
x = 30
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
