16.5 × 6.67 - 4.67 × 16.5
Answers
- (PEMDAS) if there are no parentheses then multiply first. so you would do 16.5•6.67 to get 110.055 and so the same with the -4.67•16.5 to get -77.055. now, you would subtract and your equation would now be 110.055-77.055=33. hope that helps some

Answers
Answer: C
Step-by-step explanation: just did the quiz
Using function concepts, it is found that the range of the inverse function is:
[tex]y \geq 5[/tex]
The range of a function is the data-set that contains all possible values the function can assume, that is, the values of y.In the inverse function, the inputs and outputs are exchanged, that is, the values of x on the function are the values of y on the inverse, and the values of y on the original function are the values of x on the inverse function, thus, the domain and range are also exchanged.In the original function, x assumes values in the interval [tex]x \geq 5[/tex], hence, in the inverse function, the values assumed by y, which is the range, is [tex]y = \geq 5[/tex]

A customer at a store paid $42 for 4 pairs of pants and 3 shirts. At the same store, a second customer paid $2 more for 1 pair of pants and 7 shirts. The price of each pair of pants is the same, and the price of each shirt is the same. Which system of equations can be used to find the price in dollars of each pair of pants, x, and each shirt, y?
Answers
Answer:
The system of Equations:
4x + 3y = 42
x + 7y = 44
Step-by-step explanation:
Let the price in dollars of
each pair of pants = x
each shirt = y
A customer at a store paid $42 for 4 pairs of pants and 3 shirts.
Hence:
4 × x + 3 × y = $42
4x + 3y = 42
At the same store, a second customer paid $2 more for 1 pair of pants and 7 shirts.
This means he, paid $42 +$2 = $44
Hence:
1 × x + 7 × y = 44
x + 7y = 44
The system of equations can be used to find the price in dollars of each pair of pants, x, and each shirt, y is
4x + 3y = 42.... Equation 1
x + 7y = 44..... Equation 2
Solve the system of linear equations by multiplying.
{−2x + 2y =4
{−4x + 8y =24
Answers
Answer:
The solution set is (2,4).
Step-by-step explanation:
Given that:
−2x + 2y =4 Eqn 1
−4x + 8y =24 Eqn 2
Multiplying Eqn 1 by -2
-2(-2x+2y=4)
4x-4y= -8 Eqn 3
Adding Eqn 2 and 3
(-4x+8y)+(4x-4y)=24-8
-4x+8y+4x-4y=16
4y=16
Dividing both sides by 4
[tex]\frac{4y}{4}=\frac{16}{4}\\y=4[/tex]
Putting y=4 in Eqn 1
-2x+2(4)=4
-2x+8=4
-2x=4-8
-2x=-4
Dividing both sides by -2
[tex]\frac{-2x}{-2}=\frac{-4}{-2}\\x=2[/tex]
Hence,
The solution set is (2,4).

In an xy-coordinate system, Line l has a slope of –3. If the points (2, 16) and (5, t) are on Line l, what is the value of t?
A.17
B.15
C.25
D.7
Answers
See attachment for math work and answer.
The value of t is 7 and the coordinate is (5, 7). Therefore, option D is the correct answer.
Given that, in an xy-coordinate system, line l has a slope of -3. If the points (2, 16) and (5, t) are on line l.
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.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
Now, substitute m=-3, (x1, y1)=(2, 16) and (x2, y2)=(5, t) in slope formula, we get
-3 =(t-16)/(5-2)
⇒ -3 =(t-16)/3
⇒ t-16=-9
⇒ t=7
The value of t is 7 and the coordinate is (5, 7). Therefore, option D is the correct answer.

Frieda paid $132 for groceries for her family. This was 1 1/8 as much as she paid for the previous time she shopped. How much did Freda pay on her previous shopping trip
Answers
Answer:
$117.33
Step-by-step explanation:
1 1/8 = 1 + 1/8 = 8/8 + 1/8 = 9/8
She paid 9/8 what she paid the last time.
Let the amount she paid last time equal x.
$132 is 9/8 of x.
9/8 x = 132
8/9 * 9/8 x = 132 * 8/9
x = 117.33
She paid $117.33

Answers
Answer:
i believe its the second ave
Parallel lines are those lines that are always the same distance apart and parallel lines do not intersect or meet each other.
The street that is parallel to 1st Ave is 2nd Ave.
What are parallel lines?Parallel lines are those lines that are always the same distance apart and parallel lines do not intersect or meet each other.
Example:
Line A and Line B have an angle of zero between each other.
This means Line A and Line B are parallel to each other.
We have,
Five streets:
1st ave
2nd ave
Central ave

Main road
Now,
Central Ave and the main road are parallel to each other.
1st Ave and 2nd Ave are parallel to each other.
D Street is perpendicular to 1st Ave and 2nd Ave.
Central Ave and Main Road are also perpendicular to 1st Ave and 2nd Ave.

The length of a rectangle is 3 inches less than its width the area of the rectangle is 18 in.² what are the dimensions of the rectangle
Answers
Answer:
w=6 in
l=3 in
Step-by-step explanation:
let w = width and length be 'w-3'
Two sides of w and two sides of (w-3) equal 18 sq in
18=2(w)+2(w-3)
18=2w+2w-6
4w=24
w=6
The width of rectangle is, 6 in.
And, Length of rectangle is 3 in.
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The length of a rectangle is 3 inches less than its width
And, the area of the rectangle is 18 in.²
Now, We know that;
Area of rectangle = Length × Width
Let the width of rectangle = x
Hence, Length of rectangle = x - 3
Thus, We get;
Area of rectangle = Length × Width
18 = x (x - 3)
18 = x² - 3x
x² - 3x - 18 = 0
x² - (6 - 3)x - 18 = 0
x² - 6x + 3x -18 = 0
x(x - 6) + 3 (x - 6) = 0
(x - 6) (x + 3) = 0
x = 6 , x = - 3
But dimensions are not negative.
Hence, We get;
x = 6
Thus, the width of rectangle = 6 in.
Hence, Length of rectangle = x - 3
= 6 - 3 = 3 in.
