Answer:   1.50+5m=76.50 m=15

Step-by-step explanation:

The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

pick-up fee = $1.50 plus $5 per mile

Since, m is the number of miles in the taxi ride

So, equation for pick-up fee for m miles,

pick-up fee = $1.50 + $5m

Now total fare = $76,50

Thus, required equation to determine m is given as,

1.50 + 5m = 76.50

Subtracting 1.5 both the side we get,

1.50 + 5m - 1.5 = 76.50 - 1.5

⇒ 5m = 75

or, m = 75/5

⇒ m = 15

Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

Answer:

1. B: 12 BB 18 FB,, 2.

Step-by-step explanation:

1. make the equation (198 + 33x) + 24x = 882 because there are a certain number of each ball (x) and 6 more footballs. since each football is 33 dollars, you do 33 x 6 which is 198, and then keep 33x and 24x. It is all equal to 882 since that is the final price. First, you subtract 198 on each side and combine the like terms (33x + 24x). Now it is 684= 57x and you divide 684 by 57, which equals 12. That means that there are 12 basketballs and 12 + 6 footballs, which is 18.

The value of y is -8

"The slope of tee line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"

"The point at which the graph intersects the Y-axis."

"y = mx + c, where m is the slope of the line and c is the Y-intercept."

For given question,

We have been given the graph of a line.

From the graph, we can observe that the line is passing through the points (4, 4) and (-6, 0)

Using slope formula the slope of the line would be,

[tex]\Rightarrow m=\frac{4-(-6)}{4-0}\\\\\Rightarrow m=\frac{10}{4}\\\\\Rightarrow m=\frac{5}{2}[/tex]

Also, the line intersects y-axis at y = 2

This means the y-intercept is c = 2

Using the slope-intercept form of the line the equation of the line would be,

[tex]y=mx+c\\\\y=\frac{5}{2}x+2[/tex]

Point E(-4, y) lies on the given line.

So, this point satisfies the equation of the line.

[tex]\Rightarrow y=\frac{5}{2}(-4)+2\\\\ \Rightarrow y=-10+2\\\\\Rightarrow y=-8[/tex]

Therefore, the value of y is -8

The required simplified expression of the given expression 10x -(-7+6x) is 4x - 7.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
To simplify the expression 10x -(-7+6x), we can apply the distributive property of multiplication over addition and simplify the expression inside the brackets first.

-(-7+6x) = -1×(-7) + (-1)×6x
          = 7 - 6x

Substituting this result into the original expression gives:

10x -(-7+6x) = 10x + 7 - 6x

Now we can combine like terms by adding the x terms and the constant terms separately:

= (10x - 6x) + 7

= 4x - 7

Therefore, 10x -(-7+6x) simplifies to 4x - 7.

By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides.

The triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is​ acute angle triangle.

How to find the type of triangle?

By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides. Thus,

           [tex]c^2=a^2+b^2[/tex]

       By this law it is observed that,

         [tex]c^2<(a^2+b^2)[/tex]

        [tex]c^2>(a^2+b^2)[/tex]

The sides of the given triangle are  3.8 cm ,3.7 cm, and 5 cm.

Here the longest side is 5 cm. Thus check the type of triangle using above formula. Longest side,

[tex]c^2=5^2\\c^2=25[/tex]

Other two sides,

[tex]a^2+b^2=3.8^2+3.7^2\\a^2+b^2=14.44+13.69\\a^2+b^2=28.13[/tex]

Therefore,

[tex]25<28.13\\[/tex]

Hence the triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is​ acute angle triangle.

x 100% = 55%

Answer:

66 is 55% of 120

Step-by-step explanation:

66 = 120 * x%

percent just means out of 100

for example, 20% is equal to 20/100

so, x% is x/100

66 = 120 * x/100

66/[tex]\frac{x}{100}[/tex] = 120

66 * 100/x = 120

6600/x = 120

cross multiply

6600/x = 120/1

6600 * 1 = x * 120

6600/120 = x

x = 55
