Answer:
Lindsay used 16/24 yards of fabric and has 5/24 yards left over
Step-by-step explanation:
7/8 - 2/3 = ?
Since both fractions have unlike denominators, we are gonna have to rewrite the fractions so we can subtract. We are gonna find the least common denominators, to be able to subtract.
(7/8 x 3/3) - (2/3 x 8/8) = ?
Complete the multiplication and the equation becomes :
21/24 (7/8) - 16/24 (2/3) = 5/24
Line segment XY has endpoints X(5, 7) and Y(– 3, 3). Find the equation for the perpendicular bisector of line segment XY.
A. 2x + y = 7
B. x + 2y = 11
C. 2x – y = – 3
D. x – 2y = – 9
Answer:b
Step-by-step explanation:
The equation for the perpendicular bisector of line segment XY is 2x + y = 7, the correct option is A.
What is the standard equation of a line?The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
The line segment XY has the points X(5, 7) and Y(–3, 3).
The slope of the line is,
m = ( 3 - 7) /( -3 - 5)
m = -4 / -8
m = 1 /2
The product of the slope of a line and a line perpendicular to it is -1.
( 1/2) * m' = -1
m' = -2
As it is a bisector , the midpoint of X and Y will be the point on the line.
Midpoint of XY is ( ( 5 -3)/2 , (7+3)/2 )
Midpoint of XY is ( 1 , 5)
The equation of the perpendicular bisector of line segment XY is,
y = -2x +c
5 = -2 + c
c = 7
So, the equation is,
y = -2x +7
2x +y = 7

In Cherokee County, the fine for speeding is $17 for each mile per hour the driver is traveling over the posted speed limit. In Cherokee County, Kirk was fined $221 for speeding on a road with a posted speed limit of 30 mph miles per hour. Kirk was fined for traveling at what speed, in miles per hour?
Answer:13 miles over the speed limit
Step-by-step explanation:
Answer:
H
Step-by-step explanation:
The fine for speeding is $17 mile per hour. Thus, for speeding for a total of x miles per hour above the posted speed limit of 30 mile per hour, there will be a fine of: 17(x - 30)
X in the equation is the speed of the driver and the negative sign in the equation shows that the driver was traveling at a total speed greater than the posted speed limit (thus, x - 30 is the speed above the posted speed limit in which the driver will be fined for).
Since the driver was fined $221, the equation becomes:
17(x - 30) = 221
divide both sides by 17
x - 30 = 221/17
x - 30 = 13
x = 13 + 30
x = 43
The driver was fined for travelling at a speed of 43 miles per hour which is 13 greater than the posted speed limit.

5x-10+2x=7+7x-17
Choose the Correct answer below:
Sometimes true
Never true
Always true
Answer:
always true
Step-by-step explanation:
Simplify, and if possible solve the equation to find out
remember, inverse operations
5x - 10 + 2x = 7 + 7x - 17
simplify both sides
7x - 10 = 7x - 10
this is an identity, no matter the value of x put in, the equation will be true,
hence the equation is always true

Michelle invests $15,000 in a partnership that has four other partners.The total investment of all partners is $ 240,000. What percent of the business does Michelle own?
Michelle owns about 6.25% of the total investment.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Michelle invests $15,000 in a partnership that has four other partners. The total investment of all partners is $240,000.
The percentage of investment will be calculated as below:-
Percentage = ( 15000 / 240000 ) x 100 %
Percentage = 00625 x 100%
Percentage = 6.25%
Therefore, Michelle owns about 6.25% of the total investment.

Why does the base matter when simplifying negative exponents?
Answer:
A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, "x–2" (pronounced as "ecks to the minus two") just means "x2, but underneath, as in 1 x 2 \frac{1}{x^2} x21 ".
Step-by-step explanation:
Consider the equation 1.2x + 4.8y = 18
If we graph the equation, what is the slope of the graph?
Answer:
-1/4
Step-by-step explanation:
For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.
In order to convert this equation to Slope-Intercept Form, you must first isolate y What is the first step in isolating y? 4x + 5y = 10
A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.
B. Use the Addition Property of Equality to add 5y to both sides of the equation.
C. Use the Division Property of Equality to divide the equation by 4.
D.
Use the Subtraction Property of Equality to subtract 10 from both sides of the equation.
Answer:
A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.
Step-by-step explanation:
Given equation is 4x + 5y = 10
we have to convert it in slope intercept form
slope intercept form is given by y = mx + c
now seeing the slop intercept form ,
we can say that
we have to isolate y , for that we have to remove 4x from
4x + 5y = 10 from RHS of the equation
to do that we have to subtract 4x from both side as shown below
4x + 5y - 4x = 10 - 4x
this step is called Subtraction Property of Equality to subtract 4x from both sides of the equation
and hence option A is the correct choice
Answer:
A. Use the Subtraction Property of Equality to subtract 4x from both sides of the equation.

Answer:
as below
Step-by-step explanation:

x^2 = - 9
sqrt ( x^2) = sqrt (-9) :o sqrt of a negative? yes.. use i for the negative.. this is a complex number .. hope you've been studying those
x = i* sqrt (9)
+- x = i3 so there are technically two answers
x=i3
