Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
Add 8x to both sides
-15x + 8x - 40 = 23
-7x - 40 = 23
Add 40 to both sides
- 7x = 23 + 40
-7x = 63
Divide both sides by (-7)
x = 63/-7
x = -9
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
add 8x to both sides to bring -8x to the left side
-15x + 8x - 40 = 23
add 40 to both sides to bring -40 to the right side
-15x + 8x = 23 + 40
add the common terms
-7x = 63
for x to be alone divide -7 to both sides
x = -9

. Simplify an expression for the perimeter of the equilateral triangle shown below.
Answer:
1.75×2-2
Step-by-step explanation:
look at the answer
The perimeter of the equilateral triangle with side length 1.75x - 2 is 5.25x - 6.
What is Perimeter?Perimeter of a geometrical shape is defined as the total boundary length. The perimeter of a shape can be calculated by adding the length of all the sides.
Perimeter of regular shape can be calculated by multiplying the length of the side with the total number of sides since a regular shape has all sides equal.
Here, we have an equilateral triangle with length of a side = 1.75x - 2.
Equilateral triangle is a regular shape, with all it's sides are equal.
Perimeter of an equilateral triangle with side length x is 3x.
Therefore,
Perimeter of this triangle = 3 ( 1.75x - 2 )
By distributive property, a (b + c) = ab + ac.
Perimeter = (3 × 1.75x) - (3 × 2)
= 5.25x - 6
Hence the perimeter of the equilateral triangle shown is 1.75x - 2.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.
10 pages = 20 minutes
15 pages = 15 x 20/10 minutes
15 pages = 30 minutes
The number of minutes at which Yolanda will have read the same number of pages as Jasmine is 30 minutes.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Yolanda:
0.5 pages = 1 minute
Multiply 10/0.5 on both sides.
10 pages = 10/0.5 x 1 minute
10 pages = 20 minutes
Jasmin:
0.25 page = 1 minute
1 page = 4 minutes
15 pages = 60 minutes
Now,
The time at which Yolanda will read 15 pages
10 pages = 20 minutes
15 pages = 15 x 20/10 minutes

Give the domain and range of each relationship. Determine whether or not each relationship is a function.
Answer:
Domain={2,5,8}
Range={1,3,6}
Function: YES
Step-by-step explanation:
The Domain of a Function
Is the set of values the input variable x takes.
Range of a Function
It's the set of values the output function takes when x moves into the function's domain.
A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.
Following the definitions above, the domain of the relationship is the set of input values:
Domain={2,5,8}
The range is the set of output values:
Range={1,3,6}
Since each element in the input set is related only to one element in the range, the given relationship is a function.
Answers:

which equation represents a line that passes through points (0, 6) and (2, 0) y = -1/3x + 2 y = -1/3x + 6 y = -3x + 2 y = -3x + 6
The answer is y = 3x + 6. I corrected it to 3x becuase it wouldn't work if it was -3x. If -3x is one of the choices then mark that as the answer.
which equation represents a line that passes through points (0, 6) and (2, 0)
y = -1/3x + 2
y = -1/3x + 6
y = -3x + 2
y = 3x + 6
We have to plug in the coordinates into the equation. If x or y solved from the equation equal a coordinate in the coordinates, then it will be the correct equation.
1) 6 = -1/3x + 2
-1/3x = 4
x = 12
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (0,6).
2) 6 = -1/3x + 6
-1/3x = 0
x = 0
0 = -3x + 2
-3x = -2
x = 2/3
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (2,0).
3) 6 = -3x + 2
-3x = 4
x = -4/3
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (0,6).
4) 6 = 3x + 6
3x = 0
x = 0
0 = 3x + 6
3x = 6
x = 2

You want to measure the length of a ribbon in inches. You only have a centimeter ruler. The length of the ribbon is 15 cm. Is the ribbon longer or shorter than 15 inches? How many inches long is it?
Answer:
Shorter than 15IN, 5.9 or 6 inches
Hope this helps:)
Step-by-step explanation:
The ribbon is shorter than 15 inches, and its length is approximately 5.91 inches.
Given that a ribbon has a length of 15 cm, we need to calculate the length in inches,
To determine the length of the ribbon in inches, we need to convert the length from centimeters to inches.
To convert centimeters to inches, we can use the conversion factor 1 inch = 2.54 centimeters.
The length of the ribbon is 15 centimeters. To convert this to inches, we divide 15 by 2.54:
15 cm / 2.54 cm/inch = 5.91 inches (rounded to two decimal places).
So, the ribbon is shorter than 15 inches.
The ribbon is approximately 5.91 inches long.

There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?
Answer:
I think the answer is 171.
Step-by-step explanation:
Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)
