The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total?

Answers

Answer:

The number of small vehicles washed in total = 60

Step-by-step explanation:

Amount of money that soccer team selected at a car wash fundraiser = $800

Amount of money charged for small vehicles = $5

Amount of money charged for larger vehicles = $10

The amount collected can be modeled by the equation 5x + 10y = 800 , where x represents the number of small vehicles and y represents the number of larger vehicles

Now, the number of larger vehicles washed was 50 and we need to find the number of small vehicles washed.

So, y = 50 and find the value of x from the modeled equation

⇒ 5x + 10y = 800

⇒ 5x + 10 × 50 = 800

⇒ 5x + 500 = 800

⇒ 5x = 300

⇒ x = 60

Thus, The number of small vehicles washed in total = 60

So, we know this:

5x+10y = 800

and we also know that the number of larger vehicles was 50.

So we can substitute:

5x+10y = 800

5x+10*50 = 800

and calculate:

5x+500 = 800

and now subtract 500 from both sides:

5x=300

and divide by 5:

x=60.

and this is our answer: there were 60 smaller vehicles washed!

The product of two consecutive integers is 156. Find the integers. a. 10 and 13 b. 12 and 13 c. 12 and 11 d. 1 and 13

Answers

Answer:

b. 12 and 13

Step-by-step explanation:

let x be the 1st number and x + 1 is the 2nd number

x(x+1) = 156

x² + x - 156 = 0

(x+13)(x-12)=0

x+13=0

x = -13

x-12=0

x = 12

∴ the 1st number is 12 and the second number is 13

PLEASE HELP!!!The points A, B, C, and D are plotted on a line, consecutively. AB = BC = CD = 6 cm. Find the distance between M and N, which are the midpoints of segments AB and CD , respectively. Fill in the blanks of the Statement/Reason solution.

Answers

The distance between $M$ and $N$ , which are the midpoints of segments $AB$ and $CD$ is $12cm$ .

What is segment?

Segment is a part of a line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints.

What is line?

Line is defined as a straight $1D$ figure having no thickness and extending infinitely in both directions.

We have,

$AB=BC=CD=6cm$ ,

And, $M$ and $N$ are the midpoints of segments $AB$ and $CD$ .

According to question,

$AB=BC=CD=6cm$ ,

So,

Total length of line is $18cm$ .

As $M$ and $N$ are midpoints of and $AB$ and $CD$ ,

So,

$MN=18-(AM+BN)$

$MN=18-6$

$MN=12cm$

Hence, we can say that the distance between $M$ and $N$ , which are the midpoints of segments $AB$ and $CD$ is $12cm$ .
