AlgebrA PraCtice Test 2?

We Answered:

1)
Let the numbers be x and y
Average = (x+y)/2 =5
x+y = 10 ------(1)
xy=24 ----(2)
y=24/x
plug this y into (1)
x+24/x =10
x^2+24=10x
x^2-10x+24=0
(x-6)(x-4)=0
x=6, x=4
The numbers are 6 and 4 (or 4 and 6)
The positive difference is 2

2) None

3) 5x = sqrt(36)-sqrt(25)
5x=6-5
5x=1
x=1/5

4)
2a - b > a+b
add b to both sides
2a > a+2b
Subtract a from both sides
a > 2b

help with college algebra practice exam problem?

We Answered:

I'll just set them up. These are not special or sole possibilities.

1. Let his sales be S.
Then he is being paid, in dollars,
500 + .04[2500] + 0.06[S-2500] assuming S>2500, or
500 + .04S otherwise.

2. Let the speed on the first trip be s.
section time = section distance/ section speed
First section time + Second section time = 150mi/s + 80/[s-20]
so we're effectively solving
4 = 150/s + 80/[s-20].

i need help with algebra practice problems?

We Answered:

make the other variable a zero
x + 0 = 2
x = 2
y + 0 = 2
y = 2
so it will be (2,2)

and for the second one i would do y = mx + b
1/2y = x + 2
divide 1/2 both sides on all numbers and vaiables to get y by itself
y = 1/2x + 1

and i think thats it! :)

Algebra practice work-Need to double check answer?

We Answered:

let t be the tens digit and o be the ones digit

t + o = 12
t = o + 2

substitute

(o + 2) + o = 12

gather like terms

2o = 10

divide by 2

o = 5

substitute this value into the equation t = o + 2

t = (5) + 2

t = 7

Since t = 7 and o = 5, 75 is the correct answer good work!
