2x+5×-8=12-10 how do slove it
Answers
when dealing with equations, do the same to both sides so the equation will stay equal
first group like terms
2x+5(-8)=12-10
negative times positive=negative
2x-40=2
add 40 to BOTH SIDES
2x=42
divide BOTH sides by 2
x=21
2x + 5(-8) = 12 - 10
Distribute
2x - 40 = 12 - 10
Collect Like Terms
2x - 40 = 2
Add 40 to both sides
2x = 42
Divide both sides by 2
x = 21

Answer:
3000 gallons of 12 percent is required
Step-by-step explanation:
We can use the formula
percentage * amount + percentage * amount = percentage*total amount
We have 9 percent and 15 percent wine that we are mixing to get 12 percent wine.
We are adding g gallons and 3000 gallons to get a total of (g+3000) gallons
Substituting this information in
.09 *g + .15 * 3000 = .12 (g+3000)
Distribute
.09g +450 = .12g+360
Subtract .9g from each side
.09g-.09g +450 = .12g-0.09g+360
450 = .03g + 360
Subtract 360 from each side
450-360 = .03g
90 =.03g
Divide each side by .03
90/.03 = .03g/03
3000 = g

The arrangement of the measurements from the shortest to longest is:
1 mm, 1 cm, 1 m, 1 km
The given measurements are:
1 cm, 1 m, 1 mm, and 1 km
Convert all the measurements to meters
1 cm = 1/100 m
1 cm = 0.01 m
1 mm = 1/1000 m
1 mm = 0.001 m
1 km = 1 x 1000 m
1 km = 1000 m
By considering the meter equivalents of the measurements given, the arrangement from shortest to longest is:
1 mm, 1 cm, 1 m, 1 km

Step-by-step explanation:
Answer:
The ratio of the area in the drawing to the actual area is 1 square centimeter:4 square feet.
Step-by-step explanation:
Find the number of feet represented by 1 centimeter in the scale drawing.
1 cm
2 ft
1 centimeter in the drawing equals 2 feet on the actual floor.
Step 2:
Find the side length of the floor in the scale drawing.
The area of the square in the drawing is 64 square centimeters, so the side length must be 8 cm.
Step 3:
Find the side length of the actual floor represented by 8 cm in the scale model.
1 cm × 8
2 ft × 8
=
8 cm
16 ft
The side length of the actual floor is 16 ft.
Step 4:
Since the area of a square is the side length squared, the area of the actual floor is 256 square feet.
Step 5:
The ratio of the area in the drawing to the actual area is 64 square centimeters:256 square feet.
Simplify the ratio.
The ratio of the area in the drawing to the actual area is 1 square centimeter:4 square feet.

Answer:
It is 88
Step-by-step explanation:
It is so because fist you do all the math leading it to be 88.
Final answer:
An area model visualizes the process of solving division. To determine the quotient of 8,552 and 16, draw a rectangle for the dividend (8,552), divide it into parts for the divisor (16), fill in each part until the area is filled, and then add up all parts of the quotient, which will lead you to the result 534.
Explanation:
An area model is a mathematical representation that helps show the product of two numbers in terms of areas. To find the quotient of 8,552 and 16, let's follow some steps:
- Draw a rectangle and label the area 8,552 - this will represent our dividend.
- Then we separate this rectangle into several parts. The number of these parts will represent our divisor i.e., 16.
- Each separate part or subsection represents a part of the final quotient. The area that is equal to 480 will give us 480/16 = 30. Continue filling the areas until the entire area (8,552) is filled.
- At the end, sum all parts of the quotient to get the final answer.
So, if you repeat these steps properly, you should find that 8,552 divided by 16 equals 534.
