18 x 5 Use mental math to solve. Find as many strategies as you can to solve. Record and describe each strategy.

Answers

Answer 1

Answer:

Here are a few ways that I do that:

18 * 5 is the same as (10 + 8) * 5, which equals 50 + 40, which is 90

It's also the same as (20 - 2) * 5, which equals 100 - 10, again, 90

It's also 9 * 2 * 5, which equals 9 * 10, or 90

It's also 3 * 6 * 5, or 3 * 30, which is 90.

Answers

Answer:

Ya

Step-by-step explanation:

Each rectangle can be divided into 10 parts.

What is fraction?

A fraction is a part of a whole quantity.

In a fraction, the denominator represents the number of equal parts in a whole, and the numerator represents how many parts are being considered.

Given,

Same size rectangles are cut into same number of equal parts.

Shaded part on one rectangle = 2/5

Shaded part on other rectangle = 1/2

Denominator shows total parts of whole,

To get the same number of equal parts, we need to find

Hank bought 3 more boxes of cereal than gallons of milk. He bought x boxes of cereal at $2.79 each. Each gallon of milk costs $4.49. Consider the expression 2.79x + 4.49 (x-3).
A. The term x- 3 represents the number of gallons of milk.

B. The coefficient 2.79 represents the cost of one box of cereal.

C. The expression represents the total number of boxes of cereal and gallons of milk.

Answers

Answer: all statements are true.

Step-to-step explanation:

Given: Cost of 1 box of cereal =$2.79

Cost of x boxes of cereal= $2.79 x

Each gallon of milk costs $4.49.

Hank bought 3 more boxes of cereal than gallons of milk.

gallons of milk = x-3

Total cost = (cost per box of cereal) × (x) +(Cost per gallon of milk) × (x-3)

= 2.79x + 4.49 (x-3)

All statements are correct:

A. The term x- 3 represents the number of gallons of milk.

B. The coefficient 2.79 represents the cost of one box of cereal.

C. The expression represents the total number of boxes of cereal and gallons of milk.

i am sorry if my answer was wrong but i got this .

The total perimeter is 66.
assume the width is x

Thus ,

(2x-9) + (2x-9) + x + x = 66
2x - 9 + 2x - 9 + 2x = 66
6x - 18 = 66
x = 14

Thus the width is 14 ,
the length is 2x - 9 , 2(14) - 9 = 19

Step-by-step explanation:

Since every 5 pumpkins is 8 pounds, we just need to divide 50 by 5, and times that number by 8 pounds to find the answer.

50/5 is 10.

10 x 8 = 80

Or, since 25 are 50 pounds, and 25 +25 = 50, you ad 40 to 40, giving you the answer 80.

what are the steps for solving
6x-1=-x+9

Answers

Answer:

x=10/7

Let's solve your equation step-by-step

6x−1=−x+9

Step 1: Add x to both sides

6x−1+x=−x+9+x

7x−1=9

Step 2: Add 1 to both sides

7x−1+1=9+1

7x=10

Step 3: Divide both sides by 7

7x/7=10/7

x=10/7

Answer:

x = 10 / 7

Step-by-step explanation:

6x - 1 = -x + 9

Add 1 to both sides of the equation.

6x - 1 = -x + 9

6x - 1 + 1 = -x + 9 + 1

Simplify

Add the numbers

6x - 1 + 1 = -x + 9 + 1

6x = -x + 9 + 1

Add the numbers

6x = -x + 9 + 1

6x = -x + 10

Add x to both sides of the equation.

6x = -x + 10

6x + x = -x + 10 + x

Simplify

Combine like terms

6x + x = -x + 10 + x

7x = -x + 10 + x

Combine like terms

7x = -x + 10 + x

7x = 10

Divide both sides of the equation by the same term

7x = 10

7x/7 = 10/7

Simplify

Cancel terms that are in both the numerator and denominator.

7x/7 = 10/7

x = 10/7

Solution

x = 10/7

The different measuring instruments to be used in the economic/business system of the new civilization is discussed below in detail.

Step-by-step explanation:

Economics is the research of how people allocate limited resources for generation, circulation, and consumption, both personally and collectively.

Two significant types of economics are microeconomics, which concentrates on the performance of individual customers and generators, and macroeconomics, which measures overall economies on a local, nationwide, or global scale.

Economics is especially concerned with performance in generation and exchange and practices models and opinions to assume how to generate incentives and procedures that will maximize productivity.

Economists formulate and announce numerous economic symbols, such as the Consumer Price Index (CPI). and gross domestic product (GDP).

Capitalism, communism, and socialism are examples of economic systems.

Decrease £313 by 62%
Give your answer rounded to 2 DP.

Answers

Answer:

194.06

Step-by-step explanation:

£313 decreased by 62% is £118.94

In order to determine the answer, the first step to take is to determine the value of 62% of £313.

Value of 62% = 62% x £313

0.62 x £313 = £194.06

The second step is to subtract the value of 62% of £313 from £313

£313 - £194.06 = £118.94

In order to decrease £313 by 62%, the first step is to determine the value of 62% of £313 and then subtract the value gotten from the previous step from £313.
