Answer:

6 toppings

Step-by-step explanation:

The t in this equation represents the amount of toppings.

22 + 0.65t = 26

-22 -22

0.65t = 4

0.65t/0.65 = 4/0.65

t = 6

They could get 6 toppings and the total would be $25.90.

Answer:

There are 12 quarters and 16 dimes

Step-by-step explanation:

Firstly, we need to know that a quarter is worth $0.25 while a dime is worth $0.10

There are 4 more dimes than quarters;

So if there are x quarters, there are x + 4 dimes

From the question we can get;

0.25(x) + 0.1(x + 4) = 4.6

0.25x + 0.1x + 0.4 = 4.6

0.35x = 4.6-0.4

0.35x = 4.2

x = 4.2/0.35

x = 12

X + 4 = 12 + 4 = 16

Answer:

The equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]

Step-by-step explanation:

We need to find equation of line in point slope form that passes through points (5,0) and (-6, -1).

The general equation of point slope form is: [tex]\mathbf{y-y_1=m(x-x_1)}[/tex]

where m is the slope of line.

We need to know Slope m

Finding Slope m

Finding Slope m using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=5, y_1=0, x_2=-6 \ and \ y_2=-1[/tex]

Putting values and finding slope

[tex]Slope=\frac{-1-0}{-6-(5)}\\Slope=\frac{-1}{-6-5}\\Slope=\frac{-1}{-11}\\Slope=\frac{1}{11}[/tex]

So , slope m is: [tex]\mathbf{m=\frac{1}{11}}[/tex]

Using point (5,0) and slope m =1/22 the equation of point-slope form is:

[tex]y-y_1=m(x-x_1)\\y-0=\frac{1}{11} (x-5)\\y=\frac{1}{11}x-\frac{5}{11}[/tex]

So, the equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]

Answer:

144

Step-by-step explanation:

Since the triangle is equilateral all the sides are equivalent, meaning you can make any 2 sides equal to eachother

4x + 32 = 12x

32 = 8x

x=4

Replace the x of one of the sides  

12(4) = 48

and since we are finding the perimeter multiply 48 by 3 since there are 3 sides

48(3)

Answer:

A. R = -18t + 1,820

B. 1,568 billions of barrels

C. approximately 101.11 years

Step-by-step explanation:

To make our equation, we'll use the form R = mt + b. M represents how many billion barrels of oil are being lost each year, which we know is 18 billion. So -18 will be our m. B is how many total barrels of oil there are, which is 1,820. So 1,820 will be our b. Now the equation looks like this:

R = -18t + 1,820

We can use this equation to answer Part B.

Replace the t with 14:

R = -18(14) + 1,820

Now solve for R:

R = -18(14) + 1,820

R = -252 + 1,820

R = 1,568

14 years from now, there will be 1,568 billions of barrels left.

To solve part C, we need to find how many years it will take for all of the oil to be used up. After it's all used up, the total amount of oil will be 0, so we can replace R with 0 and then solve for t:

0 = -18t + 1,820

Subtract 1,820 from both sides to isolate -18t:

0 - 1,820 = -18t + 1,820 - 1,820

-1,820 = -18t

Divide both sides by -18 to isolate the t:

-1,820/-18 = -18t/-18

101.11 = t

After approximately 101.11 years, all of the oil will be used up.

Answer:

13i, -13i

Step-by-step explanation:

x^2=-169

169=(13)^2

x^2=-(13)^2

the square root of -1 is i ( imaginary number )

(-13)^2=(13)^2 so x is 13i and -13i

Answer:

13i

Step-by-step explanation:

So I would solve for x

This is zero term factoring

This is a square root factor and 169's square root is 13.

However we need to factor -169

This is where imaginary numbers come in. i= Square root of -1

13i would be the answer

Answer:

<1 =100 (check explanation for why)

<2 = 80 (check explanation for why)

<3 = 100 (check explanation for why)

Step-by-step explanation:

You can get <1 from the given angle being a linear pair  to <1, so:

180= 80+ <1

100= <1

You can get <2 from being a linear pair to <1, so:

180 = 100 + <2

80 = <2

You can get <3 from being a linear pair to <2

180 = 80 + <3

100= <3

Answer:

The answer is c because 20(20) + 60 = 460 and if you plug in the number of rows for x and add the 60 you would always get the number of seats value.

The correct equation for the number of seats with respect to the number of rows will be;

s = 20r + 60

Where, s is number of seats and r is number of rows.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the power one.

Given that;

The chart shows the number of rows in an auditorium and the total number of seats.

Since, The equation is satisfy the given numbers in chart.

So, Let an equation for chart;

s = 20r + 60

Where, s is number of seats and r is number of rows.

Now, Substitute the value of r = 20 for the number of first rows in above equation we get;

s = 20 × 20 + 60

s = 400 + 60

s = 460

And, For second row, r = 45

s = 20 × 45 + 60

s = 900 + 60

s = 960

Thus, The correct equation for the number of seats with respect to the number of rows will be;

s = 20r + 60

Where, s is number of seats and r is number of rows.
