Answers

Answer:

[(7)^2 + 15]/4

[49+15]/4

[64]/4

3. 2x + x + 2x = 10 + x
Please help thank you in advance :)

Answers

Answer:

1. -10

2.x=8

3. x= 2

Step-by-step explanation:

1. x = 3, 2x+x+2x+5

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

= -6 +(-3)+(-6)+5

= -6 -3 -6 +5 Next you have to use BODMAS rule so first addition

= -6 -3 -1

= -9-1

= -10

2. 2(2x+1)+x=x+2x+18

=4x+2+x=3x+18 then collect like terms:

=4x+x+2=3x+18

=5x+2=3x+18

=5x+2-2=3x+18-2

=5x=3x+16

=5x-3x=3x-3x+16

= 2x=16

2x/2=16/2

x=8

3.2x+x+2x=10+x

=6x=10+x

=6x-x=10+x-x

=5x=10

=5x/5=10/5

x=2

I use the expression 3(2w - 10) to determine how many copies I need to make of a worksheet (w). If w = 20, how many worksheet copies do I need to make?

Answers

Answer: The number of copies of worksheet needs to be done = 90

Step-by-step explanation:

The expression used to evaluate the number of copies need to make of the worksheet (denoted as 'w') is given as 3(2w - 10).

If w=20, then the number of copies need to make of worksheet  = 3(2(20)-10)

i.e. the number of copies need to make of worksheet= 3 (40-10)

i.e. the number of copies need to make of worksheet= 3 (30)

i.e. the number of copies need to make of worksheet= 3 x 30

i.e. the number of copies need to make of worksheet= 90

Hence, if w = 20,  then the number of copies of worksheet needs to be done = 90
