Answer:
10 cent coins = 43
Step-by-step explanation:
x = 10 cent coins
y = 5 cent coins
x + y = 157, then y = 157 - x
$10 = 1000 cents
0.10x + 0.05y =1000
substitute for y:
0.10x + 0.05(157 - x) = 1000
0.10x + 7.85 - 0.05x = 1000
combine like terms:
0.05x = 2.15
x = 43
y = 114

Brittany bought 3 bracelets and 2 necklaces for $21. Each bracelet cost $5. The necklaces were all the same price. What is the cost for 1 necklace?
Answer:
The cost for 1 necklace is $3.
Step-by-step explanation:
With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:
c=3x+2y, where:
c is the total cost
x is the price per bracelet
y is the price per necklace
Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:
21=(3*5)+2y
21=15+2y
21-15=2y
6=2y
y=6/2
y=3
According to this, the answer is that the cost for 1 necklace is $3.

Answer:
x = 125
Step-by-step explanation:
Kindly check the image below
The problem we are looking at gives us the value of two intercepted arcs and wants us to find x ( which is an interior angle )
According to the image we can find an interior angle by adding the two intercepted arcs and then dividing the sum by 2
( Note that we are not given the direct intercepted arcs of x. We are given the intercepted arcs of x's supplementary angle )
That being said we need to find x's supplement in order to find x
Using the image below as a reference
x's supplement = [tex]\frac{70+40}{2}[/tex]
[tex]70 + 40 =110\\\frac{110}{2} =55[/tex]
So x's supplement = 55
Now to find x
Remember that supplementary angles have a sum of 180°
That being said we can find the missing angle (x) by subtracting the given angle (55) from 180
so x = 180 - 55
180 - 55 = 125
Hence x = 125
divide $50 in the ratio 2:3
Answer: 2:3=5
$50=5 units
divide both sides by 5
$10=1unit
times 2 both sides
$20=2 unit
if we times 3 of $10=1 unit
$30=3 unit
divided it is $20:$30

The floor tiles In the Jackson family kitchen are squares that measure 8 and 3/4 to a side. Each grid Square in the drawing measures 1/4 in to a side which is the scale of the drawing.
Answer:
Step-by-step explanation:
The aware iz 1 in 35 in
The scale of drawing is 1 inch : 27 inch
What is scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
Given that, the measurement of the tile = 27/4 inches
Side of the drawing = 1/4 inches
The scale of the drawing =
1/4 inch of drawing = 27/4 inch of tile
That means, 1 inch of the drawing = 27 inch of the tile
Therefore,
The scale of the drawing is 1 inch : 27 inch
Hence, option D is correct

What is the slope of the line?
Answer:
-3
Step-by-step explanation:
First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.
Answer:
-3
Step-by-step explanation:
slope = rise/run
rise = vertical distance
run = horizontal distance
Step 1. Find two easy to read points on the line. Use points on intersections of grid lines.
For example, choose points (0, -3) and (-1, 0).
Step 2. Start at one point, say (0, -3). We must go to the other point using only vertical and horizontal moves. Go up 3 units. That is a rise of +3. It's positive 3 since up is positive. Now go left 1 unit. That is a run of -1. It is negative because going left is negative.
Step 3.
slope = rise/run
slope = 3/(-1) = -3
Answer: slope = -3

Answer:
She paid a total of $92.93 at the salon
Step-by-step explanation:
Well it costed $72.60 but then she did the sales tax which is 8% of 72.60 and then she did a tip which was 20% of 72.60. 8% of $72.60 is 5.81 and 20% of 72.60 is 14.52. Then you would add them to get $20.33 and then you would add the $20.33 to the $72.60 to get $92.93. SO she paid a total of $92.93 at the salon.
$5.81 + $14.52 = $20.33
$20.33 + $72.60 = $92.93
