Step-by-step explanation:

my be this could help

Answer:

All I know is that the -3 should be there without the 1/3 because that makes no sense to me. And...

Step-by-step explanation:

3x+8=-4

Subtract 8 from both sides.

3x+8−8=−4−8

3x=−12

Step 2: Divide both sides by 3.

3x=−12

3       3

x=−4

Answer: Tyler's work is incorrect because when subtracting 8 from both sides of the equation, he didn't subtract it from -4. If he subtracted 8 from -4, it would've been 3x=-12.

The correct answer is x = -4

Step-by-step explanation:

you get x = -4 by subtracting 8 from each side of the equation, resulting in 3x = -12

then you divide both sides by 3, leaving you with x = -4

Answer:

$7.50

Step-by-step explanation:

4 1/2 hours total

1st hour = $1.00 ;  3 1/2 hrs remaining

2nd hour = $1.50 ;  2 1/2 hrs remaining

after 2 hours you pay $2 per hour so 2.5 x 2 = $5.00

Answer:

He incorrectly combined terms in step 2

Step-by-step explanation:

In Step 2, you can't combine 30² + 35² into (30 + 35)² so the answer is "He incorrectly combined terms in step 2".

Answer:

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

Notice: we do not have to solve for x, and y. All we really have to do is to subtract the two equations.

(-10x + 3y) - (-4x + 7y) = 9 - 1.

Taking off the parentheses, we get:

-10x + 3y + 4x - 7y = 8.

Simplifying, we get:

-6x - 4y = 8.

So, the answer is 8.

Answer:

39 tickets were given to the employees

Step-by-step explanation:

1. Approach

First, list the given information, then form an equation based on the given information. Finally, solve the equation with simplification and inverse operations.

2.Given

A total of 234 tickets were given away

5 times as many tickets were given away to listeners compared to employees

-Call the number of tickets given away to employees (x)

3. Form an equation

(Tickets_given_to_employees) + (Tickets_given_to_listeners) = (Total_tickets)

Substitute,

x + 5x = 234

Simplify,

6x + 234

Inverse operations,

6x = 234

/6      /6

x = 39

Answer:

there are 3 1/6 pieces

Step-by-step explanation:

since 3 x 1/6=3/6.

another explanation:

(3/6)/(1/6)=(3/6) x (6/1) since you multiply by inverse when dividing fractions. Then, (3/6) x (6/1) = 18/6, which equals 3.

Answer:

It would be a reflection across the x-axis, followed by a composition translation of -6 units x, and 1 unit y.

Step-by-step explanation:

If you were to graph each shape and follow this procedure, you will go from parallelogram ABCD to parallelogram A''B''C''D''.

Given:

Consider the total age of 5 children with age difference 3 years is 50 years.

To find:

The age of the youngest and oldest child.

Solution:

Let the ages of the 5 children are x-6, x-3, x, x+3, x+6.

Sum of their ages is 50 years.

[tex](x-6)+(x-3)+x+(x+3)+(x+6)=50[/tex]

[tex]5x=50[/tex]

[tex]x=\dfrac{50}{5}[/tex]

[tex]x=10[/tex]

The age of the youngest child is

[tex]10-6=4[/tex]

The age of the oldest child is

[tex]10+6=16[/tex]

Therefore, the age of youngest child is 4 years and the age of the oldest child is 16 years.

Answer:

2.9

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

First, put the line into y = mx + b form to find the slope (m)

x + 2y = 8

Subtract x from both sides

2y = -x + 8

Divide each side by 2

y = -1/2x + 4

So, the slope of this line is -1/2

Perpendicular lines have a opposite reciprocal slope, so the slope of a perpendicular line will be 2.

Answer:

1 and 1/3 yard

Step-by-step explanation:

200 divided by 150 is equal to 4 divided by 3

using a fraction calculator i did

4       3            1

-    /   -     =   1  -

1       1              3

Answer:

How many yards to make one dress?  = 1.33

Step-by-step explanation:

This is a ratio problem (fractions) used to solve an unknown.

if 200yds makes 150 dresses then let x (your unknown) be the yds needed  to make 1 dress.

200/150 = x/1

150*x = 200*1

150x = 200

150x/150 = 200/150

x = 200/150  

x = 1.33333
