What do you need to know about addition to add algebraic expressions

Answers

Answer 1

Answer:

To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same. To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same.

There are many laws that govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws.

R=115+3x

115 is his weight and 3x is Rupert gaining each month

M=145-2x

145 is his weight and -2x is Micheal losing weight

so if you plug in 6 as the x

R 133=115+3(6)

133=115+18

P 145=145-2(6)

145=145-12

Answer:

5. The answer is 2

6. Her error is that she was supposed to subtract 16 minus 12 instead of 12 minus 2.

Step-by-step explanation:

For number 5 all I did was solve.

12 + (25 - 5^2) - 2 =

12 + 0 - 2 =

12 - 2 = 10

10 ÷ 5 = 2

So, for number 5 the answer is 2.

For number 6, you should know that when there are only plus and minus signs you solve from left to right.

She instead put parentheses where there shouldn't of been, and because of that she is wrong.

Hope this helps! :)

36 is what percentage of 128?
A.
B. 28 %
C. 28.125 %
D. 4,608%

Answers

Answer:

C is the correct answer:

Solution for 36 is what percent of 128:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 128 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 128, so we can write it down as 100%=128.

4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.

5. Now we have two simple equations:

1) 100%=128

2) x%=36

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=128/36

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 36 is what percent of 128

100%/x%=128/36

(100/x)*x=(128/36)*x - we multiply both sides of the equation by x

100=3.55555555556*x - we divide both sides of the equation by (3.55555555556) to get x

100/3.55555555556=x

28.125=x

x=28.125

now we have:

36 is 28.125% of 128

"You figure you can ride Ghost Wind, then get on. Just bring him back to the stable when you're finished so I can rub him down." I dismounted, leaving the stallion with Mitchell, and headed toward the barn. Now, I truly expected that Mitchell would come after me with Ghost Wind. After all, despite my invitation, I knew Mitchell couldn't ride Ghost Wind. As far as I knew, Mitchell had never ridden more than a mule and had no idea how to ride a thoroughbred tornado like Ghost Wind. But instead of Mitchell following me, the next thing I knew, I heard a triumphant cry, turned, and saw Mitchell atop the stallion dashing across the meadow. For a moment all I could do was stand and stare. But then, as the stallion bucked, left the meadow, and headed for the woods, I suddenly found my legs and my voice, and I began running and screaming after Mitchell and the stallion. "Pull back the reins!" I hollered as I ran. "Mitchell, the reins! Pull back hard!" —The Land, Mildred D. Taylor Use the drop-down menus to answer the questions.

Answers

Answer:

8.1x^4 x 0.2 = 1.62x^4

Step-by-step explanation:

The estimated multiplication of 8.1 and 4.2 is close to 32.

What is a decimal?

A decimal is represented by a dot that separates the whole part and the fractional part of a number. Decimals can also be converted into fractions and vice versa.

Estimations are essential when we don't have a tool to calculate the exact value of something.

Given A multiplication of two decimal numbers 8.1 and 4.2.

Now 8.1 can be estimated as 8 and 4.2 can be estimated as 4 and we know 8 times 4 is 32 so, the multiplication of 8.1 and 4.2 is close to 32.

At a local park, Jared can choose between two circular paths to ride his bicycle. One path has a diameter of 240 yards, and the other has a radius of 380 yards. Jared is curious about two things. He wants to know how much farther he can ride his bike on the longer path than the shorter path if he rides his bike around the path once? Jared also wants to know how big of an area each circle covers. Use 3.14 for π.

Part A: Using the formula for circumference, find the circumference of both paths. (4 points)
Part B: Use the formula for area and solve for the area of each circle. (4 points)
Part C: How much farther can he ride his bike on the longer path if he goes around one time? (2 points)

Answers

Answer:

94.2 yards

Step-by-step explanation:

1st path = d = 120 yards

c= pie d

c= 376.8 yards

2nd yard = r = 45 yards

c = 2 pie r

c = 2(3,14)(45)

c = 282.6 yards
