Answer 1

Answer: see below

Step-by-step explanation:

Facts:

Justin jogs 3 2/3 miles every morning

Jogs 4 6/10 miles every evening.

Miles jogged per day=?

To solve this question,add the 2 fractions.This makes sense because let's say you ran 3 miles in the morning and 2 miles in the evening, nothing more nothing less, and you wanted to find how much you ran in a day, you'd add these 2 nummbers.

3 2/3 + 4 6/10

Step 1: Add the whole numbers

3 2/3 + 4 6/10

3+4= 7

7 + 2/3 + 6/10

Step 2: Find a common denominator between 10 and 3

10x1= 10

10x2= 20

10x3= 30 (works for both 3 and 10)

7 + __ + __

30 30

Step 3: Change the neumerators

Now when adding fractions this way, you have to multiply and change the neumerator:

In the 1st fraction, the original denominator was 3. And 3x10= 30, right? So you must also multiply the neumerator by 10 so that they are equivalent to each other

2x10= 20

In fraction #2, the neumerator was 6. 6x3= 18

7 + 20 + 18

30 30

7+38/30= 7 38/30= 8 8/30 miles per day

QUSTIION 2

Facts:

Last year, the tree was 5 11/12 feet long.

This year, the tree is 7 2/3 feet long.

How many feet did it grow?

Convert to decimals and subtract:

7 2/3= 7.66667

5 11/12= 5.9166667

7.66667- 5.916667= about 1.75, which becomes 1 3/4

It grew 1 3/4 feet

Mr. Peralta had $300 in his savings account in March. He continued to add money to his savings account and by August, the value of the savings account had increased by 20%. How much money is in Mr. Peralta’s account in August?
Identify and label the point on the double number line that represents the original amount of money in Mr. Peralta's savings account.

Answers

Answer:

ima say $360.correct me if im wrong-^-

Step-by-step explanation:

The total amount of money in Mr. Peralta's savings account is $360.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Mr. Peralta had $300 in his savings account in March.

By August, the value of the savings account had increased by 20%.

Let, 'x' be the total amount after an increase of 20%.

So, 120% of $300 is 'x'.

Therefore,

(120/100)×300 = x.

300×1.2 = x.

x = 360.

So, By august total money in his account is $360.

pls answer im failing math and need an A

Answers

Answer:

4. 23

4. 206

5. 75 ft

7. 6 sections

8. 6 families

Step-by-step explanation:

4. 3x + 5 is the same thing as 3 x 6 + 5 so it equals to 23

4. x to the power of 3 - 10 is equal to 6 to the power of 3 - 10 so it equals to 206

5. Formula for area of triangle = 1/2 x base x height

So, it's 1/2 x 10 x 15 = 75

7. 3/4 ÷ 1/8 = 6 (Trick: When dividing fractions, make sure to flip the fraction for the 2nd one and leave the 1st one as the same. After that, multiply them together)

8. 3 families have 4-5 pets, 2 families have 6-7 pets and 1 family have 8-9 pets. At least 4 pets means 4 pets and above. So 3 + 2 + 1 = 6 families.

4. 3x + 5. Substitute the X for 6. The expression is (3 x 6) + 5= 23.

X³ - 10. Substitute the X for 6. 6³-10= 216.

5. I'm not 100% sure but I believe that it is 75. I might be wrong.

6. 6

6th grade math please help

Answers

Answer: 9x-3x and 5x+x

Step-by-step explanation:

1. Brianna's thinking is incorrect because of course, when x is 0, the expression will equal whatever value isn't an x term. To find equivalent expression, you actually need to find which expressions have the same amount of x terms and the same value.

2. Expressions A and C are equivalent.

3. Expression A can be simplified, as you can do 9x - 3x = 6x, so your final expression would be 6x - 4. Expression C can also be simplified with 5x + x = 6x, which can then also be written as 6x - 4. This means both expressions have the same amount of x terms, and the same value, so they are equivalent.

Answer:

Below

Step-by-step explanation:

Brianna's teacher asks her which of these three expressions are equivalent to each other

Expression A: 9x−3x−4 Expression B: 12x−4 Expression C: 5x+x−4

Brianna says that all three expressions are equivalent because the value of each one is −4 when x=0.

Brianna's thinking is incorrect. Identify the error in Brianna's thinking. Determine which of the three expressions are equivalent. Explain or show your process in determining which expressions are equivalent. Enter your answers and your explanation or process in the space provided.

So let's just simplify A and C. B is already simplified.

9x-3x-4

6x-4

5x+x-4

6x-4

So yes, Brianna is incorrect. She added 3x and 9x, instead of subtracting 3x from 9x. A and C are equivalent, but B is all alone.
