Answer:

x = -10

Step-by-step explanation:

3(x+1) +5 = 2x -2

Distribute the 3 to the x+1

3x+3 +5 = 2x -2

Combine like terms

3x + 8 = 2x -2

Subtract 2x from both sides

x + 8 = -2

Subtract 8 from both sides

x = -10

Hope this helps!

Answer:

x=-10

Step-by-step explanation:

3(x+1)+ 5=2x- 2

Distribute the 3

3(x+1)+ 5=2x- 2 would equal

3x+3+5=2x-2

Combine like terms

3x+3+5=2x-2

3+5=8 So,

3x+8=2x-2

You want to get the numbers with x on one side

Subtract 8 on both sides to get 3x by itself

3x+8-8=2x-2-8

3x=2x-10

Then you have to get the 2x on the other side because you still want x on the other side so you do -2x on both sides

Which gives you

x=-10

That is your answer

David, Stephen and June share £96 in a ratio 2:3:3. How much money does each person get

AveGali [126]

Answer:

David gets £24, Stephen gets £36, and June gets £36.

Step-by-step explanation:

Firstly, add the ratio values together.

2:3:3 ⇒ 2 + 3 + 3 = 8

Next, divide £96 (your total) by 8.

£96 ÷ 8 = £12

Now, we have the number of pounds for 1 value.

Multiply 12 by each ratio value.

12 × 2 : 12 × 3 : 12 × 3

= 24:36:36

Therefore, David gets £24, Stephen gets £36, and June gets £36.

I hope this helped! I would really appreciate it if you would please mark me brainliest! Have a blessed day!

What value for C will make the expression a perfect square trinomial x2-7x+c

Tom [10]

Answer:

The value of c is 12.25

Step-by-step explanation:

we know that

A perfect square trinomial is of the form

$(x-a)^{2}=x^{2}-2ax+a^{2}$

In this problem we have

$x^{2}-7x+c$

equate the equations

$x^{2}-7x+c=x^{2}-2ax+a^{2}$

we have

the following equations

$-7x=-2ax$ -----> equation A

and

$c=a^{2}$ -----> equation B

Solve the equation A

$-7x=-2ax$

$7=2a$

$a=3.5$

Solve the equation B

$c=a^{2}$

$c=3.5^{2}=12.25$

therefore

$(x-3.5)^{2}=x^{2}-7x+12.25$

The value of c is 12.25
