Answer:

3 doors if we are excluding her own. 4 if we are not.

4, 5, 6. she does not pass 7, she enters 7.

3, 4, 5, 6. it could be argued she must first pass her own door.

that context changes the answer.

With or without tiles simplify and solve each equation below for x. record your work. a.3x-7=2
AfilCa [17]

Answer:

<u>x=3</u>

Step-by-step explanation:

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

3x-7=2

add 7 both sides of an equation.

3x-7+7=2+7

simplify.

3x=9

divide by 3 both sides of an equation.

3x/3=9/3

simplify.

9/3=3

3*3=9

9/3=3

<u>x=3 and 3=x</u>

Hope this helps!

Thanks!

Solve for X <br><br> PLEASE HELP DUE IN 10 MINS
ziro4ka [17]

Answer:

x = 8

Step-by-step explanation:

The measures of the angles in a triangle add up to equal 180°

That being said we can create an equation to solve for x

( note that this is a right triangle indicated by the square. A right triangle has a right angle which has a measure of 90° )

180 = 90 + 5x + 5 + 5x + 5

now we solve for x using basic algebra

step 1 combine like terms

90 + 5 + 5 = 100

5x + 5x = 10

now we have 180 = 100 + 10x

step 2 subtract 100 from each side

180 - 100 = 80

100 - 100 cancels out

now we have 10x = 80

step 3 divide each side by 10

10x / 10 = x

80 / 10 = 8

we're left with x = 8
