Answer:

x + 2x = 108

Step-by-step explanation:

Let x be the number of oranges sold on Thursday

The number of oranges sold on Friday is twice as many or 2 times x, 2x

The total sold on  the two days is 108.  Add the number sold on Thursday and Friday together and let it equal to 108

x + 2x = 108

So lets say you sold ‘x’ number of oranges on Thursday.On Friday you sold double,therefore ‘2x’. And altogether combining the sales on Thursday and Friday you sold 108 oranges. Therefore if we add the number of oranges sold on Thursday and Friday we will get 108 oranges.
The equation will be: x(number of oranges sold on Thursday) + 2x( number of oranges sold on Friday) = 108 (total number of oranges sold altogether)
x + 2x = 108

Help pls!!!! I’m super stuck

hi okay so if the original coords are a=(-2,0) b=(-3,-2) and c=(-5,-2), if one of the coords on the dilated triangle are (7,3), you apply that to the rest. so i think a=(7,3) b=(10.5,7) c=(17.5,7)but i’m not sure cause it says the constant is 4 but if you apply the constant of (7,3), the constant is -3.5. if you apple the constant of 4, the answers don’t really make sense.

answer: a=(7,3) b=(10.5,7) c=(17.5,7) i think

this question actually doesn’t really make sense at all. but i hope this helps lol.
I think you have to add your coordinates together which would probably give you 7.3 I’m sorry if this is not the answer

Compare the perimeter and area of the original figure to the enlarged figure using proportions.

A small rectangle has a length of 2, and a width of 1. A large rectangle has a variable length of b, and width of 2.

(StartFraction enlarged side (2) over Original side (1) EndFraction) squared = StartFraction Enlarged area (2 b) over Original area (2) EndFraction
Which statements describe true relationships? Check all that apply.
The enlarged area is 4 times the original area, which is the square of the scale factor.
The scale factor is One-half.
The enlarged perimeter is 2 times the original perimeter, which is the scale factor.
The perimeter is proportional to the scale factor and the area is proportional to the square of the scale factor.
The enlarged area and perimeter are equal.

Answer:

Step-by-step explanation:

we have that

5x – 3y – x + 6z

5x – x – 3y + 6z------> this step is correct

5 + 3yz------> is not correct

because

1) 5x-x=5---> is not correct

the correct is

5x-x=4x

2) -3y+6z=3yz-----> is not correct

the correct is

-3y+6z=3*(2z-y)

therefore ,

the correct solution is

Answer:

$10.48

Step-by-step explanation:

So what you do is, you divide the cost of the masks, by how many there are, and you get a set of numbers, then you have to find the average of those numbers.

When you divide you get these numbers:

75 / 6 = 12.5

88 / 8 = 11

101 / 10 = 10.1

166 / 20 = 8.3

You then need to find the average of them, so you add all of them together and divide by 4 since there are 4 numbers.

And you get 10.475, you round up since you can't have half of a penny.

$10.48
