Answer:

x = -1, y = 0.125

Answer: (-1,1/8)

Step-by-step explanation:

Coordinates are given in (x,y) format. The x axis runs left to right and the y axis runs up and down.

Point P is on -1 of the x axis and appears to be between 0 and .25 on the y axis. This would be half of .25. .25 is 1/4 as a fraction. Half of 1/4 is 1/8. So the coordinates for point P are (-1,1/8)

Step-by-step explanation:

Im not sure about the first two about fraction bars, a fraction bar looks like this 1/10 or 4/9, maybe the question is asking you to make a fraction of each side so that they both equal the same thing using common denominators.

In that case #2 would be 21/3= 21/7

still not sure about #1

X+32=40

subtract 32 on each side

x+32-32=40-32

x=8

At a restaurant, Mike and his three friends decided to divide the bill evenly. If the total bill was $51.24, how much did each person pay?

Write and solve an equation for the above situation. Use "b" as the variable

4b=51.24

divide each side by 4

4b/4= 51.24/4

b=12.81

Each friend spent $12.81 on the bill.

How many packages of diapers can you buy with $40 if one package costs $8?

Write and solve an equation for the above situation. Use "p" as the variable

8p=40

divide each side by 8

8p/8=40/8

p=5

You can buy 5 packages of diapers with $40

Answer:

16 meters

Step-by-step explanation:

Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling

The formula to solve for the above question is:

Diagonal² = Width² + Length²

34² = 30² + L²

Collect like terms

L² = 34² - 30²

L = √34² - 30²

L = √(256)

L = 16 meters

Therefore, the length of the ceiling is 16 meters

The sum of angles in a quadrilateral is 360°, so ... Then angles A and B are both 90°, meaning sides AD and BC are parallel.

Answer:

(2,2)

Step-by-step explanation:

2x+3y=10

x−2y=−2

​In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

2x+3y=10,x−2y=−2

To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.

2x+3y=10,2x+2(−2)y=2(−2)

Simplify.

2x+3y=10,2x−4y=−4

Subtract 2x−4y=−4 from 2x+3y=10 by subtracting like terms on each side of the equal sign.

2x−2x+3y+4y=10+4

Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.

3y+4y=10+4

Add 3y to 4y.

7y=10+4

Add 10 to 4.

7y=14

Divide both sides by 7.

y=2

Substitute 2 for y in x−2y=−2. Because the resulting equation contains only one variable, you can solve for x directly.

x−2×2=−2

Multiply −2 times 2.

x−4=−2

Add 4 to both sides of the equation.

x=2

The system is now solved.

x=2,y=2

Step-by-step explanation:

Use inverse operations. 32+4 and divide the answer by 3 which is 12.

Answer:

Question is incomplete so I'll use a reference.

Assume the person whose house the car went to is 21 miles away.

The car would have had to go back and forth so the total distance spent would be:

= 21 + 21

= 42 miles

The car uses 1 kilowatt hour to go 3 miles. Now it has to go 42 miles.

The number of kilowatt hours it will need are:

= Distance / distance per kilowatt hour

= 42 / 3

= 14 kilowatt hours

Answer:

OPTION ONE

and

OPTION FOUR

Step-by-step explanation:

100% correct edge

do not pick a and b as its not B !!!!

The value of x is the limit positive infinity when x approaches the values from the left the options one and four is correct.

We have given that,

The function, f(x) = sec(x), is plotted below.

On a coordinate plane, parabolas repeat.

The limit is a  value that a function (or sequence) approaches as the input (or index) approaches some value.

A parabola opens up approaches StartFraction pi Over 2 EndFraction, has vertex (0, 1), and approaches StartFraction pi over 2 EndFraction. The parabola flips over the x-axis at every measure of pi.

We have to determine the value for which values of x is the limit positive infinity when x approaches the values from the left.

from the graph, we have options one and four is correct.

#SPJ2

Answer: 30 inches

Step-by-step explanation:

The sides of the square are equal and so if the area is 25 inch², each side can be acquired by square rooting that figure:

= √25

= 5 inch per side for the square

Each side of the triangle is twice as long as a side of the square:

= 5 * 2

= 10 inches

There are three sides to a triangle so the perimeter is:

= 10 * 3

= 30 inches

Answer:

Answer:5 times more

Step-by-step explanation:

9.1 x 5 is 45.5

0.1 x 5 = 0.5

9.0 x 5= 45.0

0.5 + 45.0 = 45.5
