Find His Error And Correct It Plz I Beg Help Me I Will Give Brainlist And Points

Answers

Answer 1

Answer:

she didn't use distribution on the beginning of the equation

Step-by-step explanation:

6(x + 3) = 21

6x + 18 = 21

6x (+18 - 18) = 21 -18

6x = 3

6x/6 = 3/6

x = 0.5

6 (0.5 + 3) = 21

6(3.5) = 21

21 = 21

Answer 2
You have to multiply 6 by each number in the parentheses first so 6x + 18=21. subtract 18 by 18 it will cancel out then subtract it by 21 you will get 6x= 3. Then divide by 6 to get x=3/6

If you get an 85% on a quiz and the quiz is 40 questions how many questions did you get right?

Answers

Answer: 34 questions

Step-by-step explanation:

If you have 40 questions, you have to find out what each question is worth which was 2.5 points per question. Then you divide 85 percent by 2.5 points and you get your answer that you got a total of 34 questions corrects to get an 85%.

Answer:

34

Step-by-step explanation:

To do this we have to find the greater number, 100%=40 Questions. So then x=40, By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have. [tex]\frac{40}{x} =\frac{100}{85}[/tex]%

Again, the reciprocal of both sides gives [tex]\frac{x}{40} =\frac{85}{100}[/tex]. And x=34. So 85% of 40=34

Jasraj left his house and walked 1500 m east to the supermarket. He then walked another 500 m east to the comic store before walking back home the same way he came. How many kilometers did Jasraj walk altogether?

Answers

Answer:

Jasraj walked 4 kilometers all together

Step-by-step explanation:

First, add.

1,500 + 500 = 2,000

Then, multiply by 2.

2,000 × 2 = 4,000

Now, we have to convert to kilometers.

1 kilometer = 1000 meters

4,000 ÷ 1,000 = 4

So, Jasraj walked 4 kilometers!

Answers

Answer:

R=? D=? C=\pi[/tex]

Step-by-step explanation:

R is a radius, the radius is a line segment from the center of a circle.

D is a distance around. Another word for D is the perimeter.

Pi is a circle's circumference (Which never ends.)

For example: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679...

And the pi is 31,415,926,535,897.

Pi meaning is a half-radius x half-radius x circumference.
