kherson [118]

Answer:

A

Step-by-step explanation:

Just put x = 80 and y = 210 into the equation...

or put x = 40, y = 90.

A:

210 - 90 = 3(80-40)

120 = 120√

B:

210 + 90 = 3(80+40)

300 = 360×

C:

210 - 90 = 2.6(80-40)

120 = 104×

D:

210 + 90 = 2.6(80+40)

300 = 312×

you take a group of 20 people going to the movies. kids’ tickets cost $4 each, and adults tickets $6 each. your total cost is $9
brilliants [131]

The number of kids in your group is 12.

Step-by-step explanation:

Given,

Number of people = 20

Cost of each kid ticket = $4

Cost of each adult ticket = $6

Total spent = $96

Let,

x be the number of kids ticket

y be the number of adult ticket

According to given statement;

x+y=20     Eqn 1

4x+6y=96    Eqn 2

Multiplying Eqn 1 by 4

4(x+y=20)\\4x+4y=80\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(4x+6y)-(4x+4y)=96-80\\4x+6y-4x-4y=16\\2y=16

Dividing both sides by 2

\frac{2y}{2}=\frac{16}{2}\\y=8

Putting y=8 in Eqn 1

x+8=20\\x=20-8\\x=12

The number of kids in your group is 12.

Write the equation of a line that has a slope of -4 and goes through (-2,7).
Anni [7]

Answer:

y = -4x - 1

Step-by-step explanation:

Equation of a line is given as:

y = mx + b

Where

m is the slope

and

b is the y-intercept (y-axis cutting point)

Since we know slope is -4, we can write:

y= mx + b

y = -4x+ b

Given the point (-2,7) , we can say:

x = -2

and

y = 7

Plugging these 2 values, we can solve for b:

y = -4x + b

7 = -4(-2) + b

7 = 8 + b

b = 7 - 8

b = -1

Now, we have the equation:

y = -4x - 1

If it took 8 hours to clean 12 houses how many houses could be cleaned in 12 hours
Lubov Fominskaja [6]
It takes 8 hours to clean 12 houses so that’s 8/12 to find how many hours it take to clean one house, 8/12 is equal 2/3 . So it takes 2/3 of an hour to clean one house. 2/3 times 12 equals 8. So you want to find how many houses you can clean in 12 hours. The equation is 12= 2/3x , x=18. The answer is 18 houses. Check the work cus I sure didn’t lol, hope this helps
