Miguel and three of his friends went to the movies. They originally had a total of $40. Each boy had the same amount of money and spent $7.50 on a ticket. How much money did each boy have left after buying his ticket? Write and solve an equation that represents he situatio.

Answer:

x= -3

Step-by-step explanation:

Answer:

3 (x+5) =6 (use the distributive property)

3x + 15 = 6  ( subtract 15 from both sides to isolate the x-term)

3x = -9 (divide both sides by 3 to get x alone)

x= -3 (the answer )

Answer:

22.5 miles

Step-by-step explanation:

15 miles every hour, and there is 1.5 hours, so cut 15 in half, 7.5 and add that the 15

This quantity is the same as obtained when dividing 14x by 2:  7x

Answer:

B

Step-by-step explanation:

The equation is y=mx+b

m=slope

b=y-intercept

Answer:

b

Step-by-step explanation:

The slope intercept form of a line  is given by

y = mx+b  where m is the slope and b is the y intercept

Answer:

D) g(x) = 2x-8

Step-by-step explanation:

The answer is A) (3.1, 2.2)

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

2x + 4y = 15 → (2)

Substitute y = 2x - 4 into (2)

2x + 4(2x - 4) = 15 ← distribute and simplify left side

2x + 8x - 16 = 15

10x - 16 = 15 ( add 16 to both sides )

10x = 31 ( divide both sides by 10 )

x = 3.1

Substitute x = 3.1 into (1) and evaluate for y

y = 2(3.1) - 4 = 6.2 - 4 = 2.2

solution is (3.1, 2.2 ) → A

Answer:

1) 3 teaspoons

Answer:

5.5 rings

Step-by-step explanation:

Now I don't really know if this is right but to get the answer we need to know how much ounces of gold the jeweler need to make a ring and that would be 7.7 ounces of gold. Than divide 42.35 ounce by 7.7 ounces which would get you 5.5 ounces. Hopefully this helped :)

Answer:

5 rings

Answer:

10.24

Step-by-step explanation:

8.77 plus 1.47 = 10.24

Answer:

y = 10.24

Step-by-step explanation:

y - 1.47 = 8.77

=> y = 8.77 + 1.47

=> y = 10.24

Answer:

x= -9

Step-by-step explanation:

-8-3x+8=27

-8+8=0

-3x=27

divide by -3 both sides

27÷-3= -9

x= -9

Answer:

F = C/59 + 32

Step-by-step explanation:

Answer: your answer is A.

From the graph, we can find the y-intercept, or where the line intercepts the y-axis, and the slope of the line to formulate our equation.

With this information, we can write the equation of the line:

C. y = -5x + 3

*Note: the slope-intercept formula for a line is y = mx + b, where m is slope and b is the y-intercept.

Answer:

Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.

Step-by-step explanation:

Given that:

Scores of four tests

78, 89, 90 and 96

Let,

x be the score on fifth test.

Average is the sum of quantities divided by total number of quantities.

Average = 90

Average = [tex]\frac{Sum\ of\ scores}{No.\ of scores}[/tex]

Putting the values in the formula;

[tex]90=\frac{78+89+90+96+x}{5}\\90=\frac{353+x}{5}\\90*5=353+x\\450=353+x\\450-353=x\\x=97[/tex]

Hence,

Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.

Answer:

you move up and across then write it as a fraction rise over run

So the formula is (y2 - y1) / (x2 - x1)

Step-by-step explanation:

Answer:

-1.8m + 0.7

Step-by-step explanation:

Answer:

The answer is "[tex]\bold{(-\infty, \infty)}[/tex]"

Step-by-step explanation:

Given:

[tex]\to \bold{\frac{\frac{x^2-bx +ax - ab}{x2+bx-ax - ab}}{\frac{x2+bx+ax +ab}{x2-bx-ax+ab}}}[/tex]

[tex]\to \frac{x^2-bx +ax - ab}{x2+bx-ax - ab} \times \frac {x2-bx-ax+ab}{x2+bx+ax +ab}\\\\\to \frac{x(x-b) +a(x - b)}{x(x+b)-a(x +b)} \times \frac {x(x-b)-a(x-b)}{x(x+b)+a(x +b)}\\\\[/tex]

[tex]\to \frac{(x-b) (x+a)}{(x+b)(x-a)} \times \frac {(x-b)(x-a)}{(x+b)(x +a)}\\\\\to \frac{(x-b)}{(x+b)} \times \frac {(x-b)}{(x+b)}\\\\\to \frac{(x-b)^2}{(x+b)^2} \\\\[/tex]

[tex]\to f(x) = \frac{(x-b)^2}{(x+b)^2} \\\\[/tex]

So, the domain are [tex]\bold{(-\infty, \infty)}[/tex]
