Answer:
$500
Explanation:
If Joe saved 60% of the cost, given that the amount he saved was $300, to find the total cost of the computer, we need to know 100% of the cost.
60% = $300
[Set the percentage to a fraction and let x be the total cost]
(60/100) x = $300
60x / 100 = $300
_____________
60 → 30 × 2 → 15 × 2 × 2 → 5 × 3 × 2 × 2
______________________________
100 → 50 × 2 → 10 × 5 × 2 → 5 × 2 × 5 × 2
_______________________________
5 × 3 × 2 × 2 / 5 × 2 × 5 × 2 =
3 / 5.
_____________________________
3x / 5 = 300
3x / 5 × 5 = 300 × 5
3x = 1500
÷3 ÷3
x = $500

What value of b will make the equation a true statement? Explain how you arrived at your solution. (−34 + 43)+ b = 0
Answers
Answer:
b = -9
Step-by-step explanation:
Given the equation (−34 + 43)+ b = 0
We are to find the value of b
First solve for the value in parenthesis
(−34 + 43)+ b = 0
9+b = 0
Subtract 9 from both sides
9+b-9 = 0 - 9
b+0 = -9
b = -9
Hence the value of b will make the equation a true statement is -9

Tell whether the angles are complementary or supplementary. Then find the value of $x$ . A ray intersects two other rays forming a right angle. The angles formed after the intersection is x degrees and left parenthesis x minus 20 right parenthesis degrees.
Answers
The measure of the value of x is 55°.
We have,
Complementary angles are two angles that add up to 90 degrees.
Supplementary angles are two angles that add up to 180 degrees.
Now,
The ray intersects two other rays forming a right angle.
This means,
It is a complementary angle.
i.e
x + (x - 20) = 90
x + x - 20 = 90
2x = 90 + 20
2x = 110
x = 55°
Thus,
The measure of the value of x is 55°.

G( ? , b)
The x value of G is a little harder. You have to be careful what you do to c.
A is at - c which means you need to add c to get to (0,0)
In addition, you go out d units to get to F. So the x value of G = c + d
the complete answer is G(c + d,b)

Answer:
The value of the machinery after 5 years is $236.20
Step-by-step explanation:
Generally, we have the depreciation exponential expression as;
V(t) = I (1 - r)^t
V(t) is the value of the machinery at a point in time
I is the initial value or the cost of the machinery when bought which is $400
r is the rate of decrease which is 10% and is same as 10/100 = 0.1
t is the time which is 5 years
Substituting these values;
V(5) = 400( 1 - 0.1)^5
V(5) = 236.196
to the nearest vent, this is $236.20

We see the diagonals are:
(-2,-1) (6,3) and (1,3), (3,-1)The midpoint of any diagonal is the intersection of the diagonals.
Use midpoint formula to find the coordinates:
