Please help me with my homework my homework question

Mathematics

Answer:

(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.

Can't read the second question fully.

(A) 0.53

Step-by-step explanation:

Number 1:

If we have the equation 3x + 2 = 5x, our first goal is to get rid of the x term on one side.

To do this we can subtract 3x from both sides. This leaves our equation to 2=2x. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x.  This leaves x=1.

<em>I couldn't read Number 2 fully - I'm sorry :c</em>

<em></em>

Number 3:

Given the equation 3(x+0.2)=2.2, we want to isolate x on one side.

To do this, we first apply the distributive property to the left side.

3x + 0.6 = 2.2

Now subtract 0.6 from both sides:

3x=1.6

And divide both sides by 3.

x=0.5\overline{3}

This rounds to 0.53.

Hope this helped!

Answer:

B

28.78

A

Step-by-step explanation:

Equation

3x + 2 = 5x

The first step is to subtract 3x from both sides.

3x - 3x + 2 = 5x - 3x

2 = 2x

The next step is to divide by two. That's the 2 in front of the two x.

2/2 = 2x/2

1 = x

So the answer must be B

The others are just not done in the right order and give wrong answers.

Problem 3

3(x + 0.2) = 2.2

3x + 0.6 = 2.2

3x + 0.6 - 0.6 = 2.2 - 0.6

3x = 1.6

x = 1.6/3

x = 0.53

Step-by-step explanation:

ALGEBRA 1

Lilly S. asked • 08/16/17

3 girls get volunteer hours.

Katie, Elizabeth, and Siobhan voluenteer at the hospital. In a week, Katie volunteers 3 hours more than Elizabeth does and Siobhan volunteers 1 hour less than Elizabeth. Over 3 weeks, the number of hours Katie volunteers is equal to the sum of Elizabeth's and Siobhan's volunteer hours in 3 weeks.

We know nothing about Elizabeth hours, so that is where you assign the variable.

Elizabeth = X

Katie = X+3

Siobhan = X -1

Assuming this holds true over 3 weeks,

3(x+3) = 3X + 3(x-1)

3x + 9 = 3x + 3x - 3

3x + 9 = 6x - 3

0 = 6x - 3 - 3x - 9

0 = 3x - 12

12 = 3x

x=4

in one week:

Elizabeth volunteers 4 hours

Katie volunteers 7 hours

Siobhan volunteers 3 hours

over three weeks:

Elizabeth volunteers 12 hours

Katie volunteers 21 hours

Siobhan voluteers 9 hours

21 = 12 + 9, so yes it checks.

The side of one square is equal to 3m and its diagonal is equal to the side of a second square. Find the diagonal of the second
navik [9.2K]

Answer:

6m

Step-by-step explanation:

the side of first square = 3 m

area of first square = 3^2= 9 m^2

let the side of second square = x m

since diagonal of first square = x m as per the question

in a square each angle is 90 degree

therefore by applying pythagorus theorem ,

diagonal ^2 = side^2 + side ^2

diagonal^2 = 3^2+3^2=9+9

DIAGONAL= square root of 18

diagonal= 3\sqrt{2} m = side of second square

therefore in second square ,

one angle is 90  degree , therefore by applying pythagorue theorem

diaqonal^2 = side ^2 + side ^2 = (3\sqrt{2})^2 + ( 3\sqrt{2})^2

diagonal ^2 = 18 + 18

diagonal = square root of 36

therefore diagonal of second square is 6m

hope it helps you... please mark me as the brainliest..
