The 8th grade students at two middle schools are raising money by washing cars.
Eastern School has already raised $625 and charges $4.50 per car. West School
charges $6.00 per car and has already raised $475. Which of the following equations
can be used to find c, the number of cars each school needs to wash so that the total
amount raised is the same for both schools?
A. 625c +4.5 = 475c + 6
B. 4.50 +625 = 6c +475
C. 625c +6=4750 +4.5
D. 4,5c 1475 = 6c 4625

Answer:

x = (28 +- root -64) / (8)

Step-by-step explanation:

4x^2 -28x= -53 = 0

x = [-(-28)+- root (-28)^2 - 4 * 4 * 53] / 2 *4

x = (28 +- root 784 - 848) / (8)

x = (28 +- root -64) / (8)

The equation produces the values in the table is y = x/4

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

For example, 2x – 5 = 13.

Given is table (attached) we need to determine an equation that produces the values in the table,

So, seeing the value it is much that the value of x are the 4 times of the values of y,

So, we can write,

4y = x

or, y = x/4

Hence, the equation produces the values in the table is y = x/4

Answer:

1680

Step-by-step explanation:

Number of distinct Toppings wanted = 4

Total number of vegetarian topping = 8

To choose 4 distinct toppings from a total of 8

Using permutation :

nPr : n! (n - r)!

8P4 = 8! / 4!

8P4 = (8*7*6*5)

8P4 = 1680

Answer:

Your pay rate would be $7 per hour

Your friend's rate is $9 per hour

Step-by-step explanation:

To get the answer for your pay rate you'll have to divide 56/8 and then you'd  get your number 7, so you get $7 dollars per hour.

To get the number for your friends pay rate you'd also do the same thing, divide. 36/4 gives you the number 9, so your friend gets $9 dollars per hour.

Answer:

its the second, not sure about 3

Step-by-step explanation:

2^x can never be negative

g is 2^x+4, which also can never be negative

neither have a y-intercept, so im not sure about three

but they have the same domain (-inf, inf), but not the same range, as g is always greater than 4, while f can be less than 4

and thus they don't have the same asymptote

both functions have an x-intercept: 1 for f(x), 5 for g(x)

so only the second choice is correct

Answer:1250

Step-by-step explanation:

You take the highest number 2249.99 and subtract the lowest number 999.99 to get the range of 1250

The range of the prices of the computer packages is $1250.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given,

Computer packages at an electronics store are priced $1,729.99, $2,249.99, $2,139.99, $1,979.99, and $999.99.

One thousand seven hundred and twenty nine point nine nine comma two thousands two hundred forty nine point nine nine comma two thousand one hundred thirty nine point nine nine comma one  thousand nine hundred seventy nine point nine nine comma nine hundred ninety nine point nine nine.

Range is the difference between highest value minus lowest value.

Range=Highest value - Lowest value

Range=$2,249.99-$999.99.

Range=$1250

Hence, the range of the prices of the computer packages is $1250.

Answer:

30degrees

Step-by-step explanation:

The sum of angles of a triangle is 180

<A + <B + <C = 180

Substitute the given values

3x + x+10 + 6x = 180

10x + 10 = 180

10x = 180-10

10x = 170

x = 170/10

x = 17

Get <A:

<A = 3x

<A = 3(10)

<A = 30degrees

Hence the measure of angle A is 30degrees

Answer:

A) We know that she make $7 per hour, with this we can make a table:

1hr | $7

2hr | $14

3hr | $21

etc...

B)  If in one week she earns $105 and 1w = 7h (1hr = $7) holds true, that means that we have to divide 105 by 7 which gives us 15hrs

C) If she baby-sat for 24hrs, we just have to multiply that by 7 and we get $168

Answer:

-12

Step-by-step explanation:

5(-10)=-60

-60+15=

-45

Answer:

-12

Step-by-step explanation:

Reorder the terms:

15 + 5x = -45

Solving

15 + 5x = -45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 5x = -45 + -15

Combine like terms: 15 + -15 = 0

0 + 5x = -45 + -15

5x = -45 + -15

Combine like terms: -45 + -15 = -60

5x = -60

Divide each side by '5'.

x = -12 :)

Answer:

108

Step-by-step explanation:

Answer:

m = 136

Step-by-step explanation:

m/8 - 5 = 12

1. Add 5 on both sides

m/8 - 5 + 5 = 12 + 5

m/8 = 17

Multiply 8 on both sides since u are trying to isolate the variable

m/8 * 8 = 17*8

m = 136

Check

136/8 - 5 = 12

17 - 5 = 12

12 = 12

Hope it helped!

Step-by-step explanation:

[tex]\frac{m}{8}[/tex] - 5 = 12 : Original Problem

[tex]\frac{m}{8}[/tex] -5 +5 = 12 + 5 : Bringing the constants to one side

[tex]\frac{m}{8}[/tex] = 17 : Simplification

[tex]\frac{m}{8}[/tex]×8 = 17×8: Isolating the variable

m = 136 : The answer!!!

Checking the answer

[tex]\frac{136}{8}[/tex] -5 = 12 : Substitution

[tex]\frac{136}{8}[/tex] = 17 : Bringing constants to one side and simplification

136 = 17 × 8 : Isolating the answer

136 = 136 : Success!!!
