Gwendolyn is asked to solve the equation –4(x – 3) = 20. She shows the work below and states that the solution is x = –8. –4(x – 3) = 20 –4x + 12 = 20 –4x = 32 x = –8 Unfortunately, Gwendolyn's work is flawed. Explain the flaw in Gwendolyn's work. Determine the correct solution to the equation.

Answers

Answer 1

Answer:

[tex]x=-2[/tex]

Step-by-step explanation:

Given: Equation is [tex]-4(x-3)=20[/tex]

To find: flaw in Gwendolyn's work and the correct solution to the equation.

Solution:

In the given question,

the first step is [tex]-4(x-3)=20[/tex]

The second step is [tex]-4x+12=20[/tex]

(This step is obtained on multiplying [tex]-4[/tex] by [tex]x-3[/tex])

The third step is [tex]-4x=32[/tex]

This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:

[tex]-4x=20-12\\-4x=8\\x=-2[/tex]

So, the correct solution is [tex]x=-2[/tex]

Bella bought packs of stickers to give to her friends. Each pack cost $4. She spent a total of $12 on stickers. How many packs did she buy?

Which equation best represents the statement above?

Question 2 options:

12s = 4


4s = 12


4 + s = 12


12 + s = 4

Answers

Given:

Bella bought packs of stickers to give to her friends.

Cost of each pack of stickers = $4

Total amount spent on packs of stickers = $12

To find:

The equation for the given statement.

Solution:

Let s be the number of packs of stickers.

Cost of one pack of stickers = $4

Cost of s packs of stickers = $4s

Total amount spent on packs of stickers is $12. So,

[tex]4s=12[/tex]

Therefore, the correct option is B.

Which expression represents "6 more than the product of 5 and 3" ?

Answers

Answer: (5 × 3) + 6

Step-by-step explanation:

The expression that represents "6 more than the product of 5 and 3" simply means that we've to multiply 5 by 3 and then add 6. This will be:

= (5 × 3) + 6

We can then solve further to get the value.

= (5 × 3) + 6

= 15 + 6

= 21

2 x- y. 8 = 0
X-2 y. 8 = 0
2 x - y - 8 = 0

Answers

Hard to tell the answer choices so here’s what I get. See if if either of these are an answer choice.

2x + y - 8 = 0

Or

-2x - y + 8 = 0

The equation of a line in general form with a slope of - 2 and y-intercept of 8 is -2x- y + 8 = 0

Equation of a line in general form

The equation of a line in slope intercept form can be represented as follows:

y = mx + b

where

m = slopeb = y-intercept

Therefore,

y = -2x + 8

The general form equation of a line is as follows:

Ax + By + C = 0

where

A, B and C are constant

Hence,

-2x- y + 8 = 0

HELP TIME SENSITIVE: Find the missing side for the value of x round to the nearest tenth

Answers

Answer:

9.0, B

Step-by-step explanation:

Remember: SOH CAH TOA

sine is opp/hyp, cos is adj/hyp, and tan is opp/adj

In this case, you want to use tan because the sides you want to work with are the opposite and adjacent sides.

The opposite side is x, and the adjacent side is 12.

tan(x)= opp/adj

tan(37°)= x/12

12(tan(37°))= x

12(0.75))= x

9= x

So, the answer is 9.0, B.

A student worked out the following problem: Solve: 8x + 10 – 6x + 4 = 24 Step 1: 2x + 14 = 24 Step 2: 2x = 38 Step 3: x = 19

A) There is an error in step 1
B) There is an error in step 2
C) There is an error in step 3
D) There is no error

Answers

Answer

b

Step-by-step explanation:

Answer:

B) There is an error in step 2.

Step-by-step explanation:

When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).

After combing your like terms, you now have the equation 2x+14=24.

You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10

This is where the student made the mistake. Instead of subtracting 14, they added 14.

The final step would be to divide by 2 on both sides.

At the end of the problem, you are left with x=5.
