Step-by-step explanation:

Answer:

x=23

y=88

Step-by-step explanation:

3x+23 and 4x have the same degree measure because they are corresponding angles

3x+23 = 4x

x=23

4(23) + y = 180

92 + y = 180

y = 88

Answer:

$2827.5

Step-by-step explanation:

Cost of each ticket = $32.50

The school choir bought 54 tickets for the Saturday concert and 33 tickets for the Sunday concert.

Cost for Saturday concert = 32.50 × 54

= $1755

Cost for sunday concert = 32.50 × 33

= $1072.5

Total cost = Cost for Saturday concert + Cost for Sunday concert

= $1755  + $1072.5

= $2827.5

Hence, he will pay $2827.5 in all for the tickets.

Answer:

y=20-3x

Step-by-step explanation:

The equation that can be used will be y = 20 - 3x

Amount of gift card that Sandra has = $20

Amount spent each month = $3

Let the remaining amount be represented by y

Therefore, the amount that will remain after x months will be deducted from the original amount that she has which will be:

y = 20 - (3 × x)

y = 20 - 3x

Answer: (8/10)+(1/100)+2/1000)=0.812

Step-by-step explanation: Um, what is the underlined digit

Answer:

I unsure about which digit is underlined but suppose it is all three 812. Then the correct representation as a fraction is 812/1000. If the undwrlined digit was just the 8 it would be 8/10. 1 would be 1/100, and 2 would be 2/1000

Answer:

The numbers are 4, 8 and 14

Step-by-step explanation:

Determine the three numbers

We start by declaring the variables

Let the three numbers be [tex]x,\ y\ and\ z\ respectively[/tex]

Next, we write the relationships between the numbers

[tex]y = 2 * x[/tex] --- Second = Twice the first

[tex]z = 6 + y[/tex] --- Third = 6 more than second

[tex]x + y + z = 26[/tex] --- Sum of the three numbers

Then, we solve for each number

[tex]y = 2 * x[/tex]

[tex]z = 6 + y[/tex]

[tex]x + y + z = 26[/tex]

Substitute 6 + y for x in [tex]x + y + z = 26[/tex]

[tex]x + y + 6 + y =26[/tex]

Collect Like Terms

[tex]x + y + y = 26 - 6[/tex]

[tex]x + 2y = 20[/tex]

Substitute 2 * x for y in [tex]x + 2y = 20[/tex]

[tex]x + 2(2*x) = 20[/tex]

[tex]x + 4*x = 20[/tex]

[tex]x + 4x = 20[/tex]

[tex]5x = 20[/tex]

Solve for x

[tex]x = \frac{20}{5}[/tex]

[tex]x = 4[/tex]

Recall that:

[tex]y = 2 * x[/tex]

[tex]y = 2 * 4[/tex]

[tex]y = 8[/tex]

Recall that:

[tex]z = 6 + y[/tex]

[tex]z = 6 + 8[/tex]

[tex]z = 14[/tex]

Hence, the numbers are 4, 8 and 14

To test the result:

[tex]x + y + z = 26[/tex]

[tex]4 + 8 + 14 = 26[/tex]

[tex]26= 26[/tex]

Answer:

[tex]\frac{g}{2}[/tex]+[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

The zero of the given function f(x) is x = 1. The correct answer is an option (A).

To find the zero of the function f(x) = 3√(x + 3) - 6, we set the function equal to zero and solve for x:

3√(x + 3) - 6 = 0

Adding 6 to both sides:

3√(x + 3) = 6

Dividing both sides by 3:

√(x + 3) = 2

Squaring both sides to eliminate the square root:

x + 3 = 4

Subtracting 3 from both sides:

x = 1

Therefore, the zero of the function f(x) is x = 1.

Thus, the correct answer is A.

The complete question is as follows:

What is the zero of function f?

f(x)=3√(x+3)-6

A. x= 1

B. x= -3

C. x= 9

D. x= -1

Answer:

D. 129 1/6 square feet

Step-by-step explanation:

L x W = A is the equation used to solve for the area of quadrilaterals

When we substitute the values of L and W for what the length and width actually are, we end up with the equation 12 1/2 x 10 1/3 = A.

Now you just need to multiply the length and width which will give you 129 1/6 square feet.

Answer:

D

Step-by-step explanation:

imagen the inequality sign is a normal equal sign so you would just do it as a normal problem solving for the variable.

so first get n by its self so you start by gettting rid of 8.7, so to cancle it out you minus it by its self and what you do to one side you do to the other.

now you have -2.5n > -3.25

divide it by its self by both sides and you get 1.3

and because you divided by a negative your sign switches to the other side. It’s called the negative division rule

Answer:  x = 40

Step-by-step explanation:

4= x/-4 + 14    Remember that in front of every variable there is a number 1.

4 = - 1/4x  + 14  subtract 14 from both sides

-14               -14

   -10 = -1/4x    Divide both sides by -1/4

x = 40

Answer:

  20

Step-by-step explanation:

Let n, d, q represent the numbers of nickels, dimes, and quarters, respectively. Then we have ...

  n + d + q = 45

  5n +10d +25q = 700

  n -d = -5

__

Using n=d -5, we can substitute into the first two equations:

  (d -5) +d + q = 45

  2d +q = 50 . . . . add 5, collect terms [eq4]

__

  5(d -5) +10d +25q = 700

  15d +25q = 725 . . . . . . . . . . add 25, collect terms [eq5]

Multiplying [eq4] equation by 3 and subtracting that from 2/5 of [eq5], we have ...

  (2/5)(15d +25q) -3(2d +q) = (2/5)(725) -3(50)

  6d +10q -6d -3q = 290 -150

  7q = 140 . . . . . . simplify

  q = 20 . . . . . . . . divide by 7

There are 20 quarters.

Answer:

y -11 = -2(x+4)

or

y = -2x+3

Step-by-step explanation:

We can use the point slope form of a line

y - y1 = m(x-x1)  where m is the slope and (x1 ,y1) is a point on the line

y - 11 = -2(x- -4)

y -11 = -2(x+4)

We can rewrite it in slope intercept form

y-11 = -2x-8

Add 11 to each side

y = -2x+3

Answer:

the equation would be y=-2x+3

Step-by-step explanation:

you are given the slope and a point on this line, and the form for an equation of a line is y=mx+b, where m is the slope and b is the y-intercept. so since we know the slope already:

y=-2x+b

and we are given a point, (x, y), so plug in those numbers as x and y.

11=-2(-4)+b

now solve for b:

11=8+b

3=b

now plug in the slope, m, and y-intercept, b, back into the original equation:

so, y=-2x+3
