A leather jacket is priced at $130. There is an 8% sales tax rate. What is the sales tax for the jacket in dollars and cents?
Answer:
$10.40
Step-by-step explanation:
Multiply $130 with 0.08 to get the sales tax. 0.08 is the same as 8%, just in decimal form.
$130 * 0.08 = $10.40

Jasmine needs to solve the equation 9x + 12 = 3(x-8). Which
equations represent a first step Jasmine could use to solve the original
equation? Select all that apply.
Answer:
To find the value of x
1. Solve what it is in the parentheses
2. Combine like numbers on each side of the equation if is possible
3. Subtract 12 on both sides of the equation
4. Subtract 3x on both sides of the equation
5. Divide by 6 both sides of the equation
Step-by-step explanation:
9x + 12 = 3(x-8)
9x + 12 = 3x -24
-12 -12
9x = 3x -36
-3x -3x
6x = -36
6 6
x = -6
The equation that represent the first step that should be required is 9x + 12 = 3x -24.
Calculation of an equation:Since the equation is
9x + 12 = 3(x-8)
So
9x + 12 = 3x -24
6x = -36
x = -6
So based on this, we can say that The equation that represent the first step that should be required is 9x + 12 = 3x -24.

Alexandria High School scored 37 points in a football game. Six points are awarded for each touchdown. After each touchdown, the team can earn one point for the extra kick or two points for a 2-point conversion. The team scored one fewer 2-point conversions than extra kicks. The team scored 10 times during the game. How many touchdowns were made during the game?
Answer:
Five touchdowns were made in the game
Step-by-step explanation:
Here, we want to know the number of touchdowns made during the game.
We proceed as follows;
Let the number of touch downs be x
So the total points earned through touchdowns is 6 * x = 6x
The number of scores is 10 times
Let the number of extra kick be y which means that the number of conversions will be (y-1)
So the total number of score times will be ;
x + y + y-1 = 10
x + 2y = 11 •••••••••(i)
Now let’s work with points
Touch down points = 6 * x = 6x
Points from extra kick = 1 * y = y
Points from 2-point conversions = 2(y-1) = 2y - 2
So;
6x + y + 2y -2 = 37
6x + 3y = 37 + 2
6x + 3y = 39
divide through by 3
2x + y = 13 •••••••(ii)
So now solve simultaneously
From ii, y = 13 - 2x
Put this into i
x + 2(13-2x) = 11
x + 26 - 4x = 11
x -4x = 11-26
-3x = -15
x = -15/-3
x = 5
There are five touchdowns in the game
Answer:
x = -15/-3
Step-by-step explanation:
Five touchdowns were made in the game
Step-by-step explanation:
Here, we want to know the number of touchdowns made during the game.
We proceed as follows;
Let the number of touch downs be x
So the total points earned through touchdowns is 6 * x = 6x
The number of scores is 10 times
Let the number of extra kick be y which means that the number of conversions will be (y-1)
So the total number of score times will be ;
x + y + y-1 = 10
x + 2y = 11 •••••••••(i)
Now let’s work with points
Touch down points = 6 * x = 6x
Points from extra kick = 1 * y = y
Points from 2-point conversions = 2(y-1) = 2y - 2
So;
6x + y + 2y -2 = 37
6x + 3y = 37 + 2
6x + 3y = 39
divide through by 3
2x + y = 13 •••••••(ii)
So now solve simultaneously
From ii, y = 13 - 2x
Put this into i
x + 2(13-2x) = 11
x + 26 - 4x = 11
x -4x = 11-26
-3x = -15
Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. What is the unit rate at which Martin paints in wall per gallon?
35/25
1 7/25
1/2
1 3/32
Answer:
Since your answer needs to be in walls per gallon I would assume you divide 4/5 by 5/8 since that would tell you how many walls he can paint in an hour.
4/5 walls÷5/8 gallons=1.28walls/gallon.

What is the slope, the Y-intercept and the equation for this graph??
Answer:
equation of the line: y=1/2x-1
slope :1/2x
y intercept: -1
Step-by-step explanation:
using y1-y2/x1-x2:
-1-0/0-2= -1/-2=1/2
the slope is 1/2.
plug in the numbers from the given points to find the y intercept:
-1=1/2•0+b
b= -1
the y intercept is -1.
with that, you've gotten the slope and the y intercept, which means you just have to plug them into y=mx+b.
so, the equation of the line is y=1/2x-1

Write an equation of a line that passes through the point (5,1) and is parallel to the line y= (-3/5)x -3
Answer:
y = (-3/5)x + 4
Step-by-step explanation:
Parallel lines have the same slope.
So the slope to the other line would be -3/5 as well.
Slope-intercept form is y = mx + b where m is the slope.
So you substitute the slope in making it y = (-3/5)x+b.
To find b, the y-intercept, you have to plug in the point for y and x in it. So you use the point (5,1) for it. That would get to 1 = (-3/5)5 + b.
To simplify that, it would get to 1 = -3 + b
Then you add 3 on both sides getting to b = 4.
Then you substitute b in, getting y = (-3/5)x + 4.

An equation of a line that passes through the point (5,1) and is parallel to the given line is y=-3/5 x+4.
Given that, a line that passes through the point (5,1) and is parallel to the line y= (-3/5)x -3.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
We know that, the slope of a line parallel to given line is m1=m2
By comparing y= (-3/5)x -3 with y=mx+c, we get m= -3/5
So, the slope of parallel line is -3/5
Now, put m= -3/5 and (x, y)=(5, 1), that is
1=-3/5 (5)+c
c= 4
So, equation with m=-3/5 and c=4, we have y=-3/5 x+4
Therefore, an equation of a line that passes through the point (5,1) and is parallel to the given line is y=-3/5 x+4.
