Semenov [28]2 years ago

Answer:

Carrie's allowance is 7.

Step-by-step explanation:

Use the equation to find a.

a+a+8=22

First, combine like terms.

2a+8=22

Subtract 8 from both sides.

2a+8-8=22-8

2a=14

Divide 2 from both sides.

2a/2=14/2

a=7

Hope this helps!

Please help me really quick pleasee<br> answer choices:<br> a)2<br> b)11<br> c)20<br> d)29
mihalych1998 [28]

Answer:

C. x=20^{\circ}

Step-by-step explanation:

Angle 6 and angle with measure 45° are vertical angles (opposite angles whan two lines intersect). By Vertical Angles Theorem, vertical angles are congruent, so

m\angle 6=45^{\circ}

Angle 6 and angle with measure 5x+35^{\circ} are the same side interior angles when two parallel lines are cut by transversal. The same side interior angles add up to 180°, then

m\angle 6+5x+35^{\circ}=180^{\circ}\\ \\45^{\circ}+5x+35^{\circ}=180^{\circ}\\ \\5x=180^{\circ}-45^{\circ}-35^{\circ}\\ \\5x=100^{\circ}\\ \\x=20^{\circ}

Can someone explain to me in words how to do this problem 3x+122=22x-11
inn [45]

When you have this type of problem, you need to combine the like-terms and isolate the variable.

3x + 122 = 22x - 11

Add 11 to both sides to get rid of it

3x + 122 + 11 = 22x - 11 + 11     (-11 + 11=0)

3x + 133 = 22x

Then you would bring the 3x to the other side, so subtract 3x from both sides

3x + 133 = 22x

-3x             -3x

133 = 22x - 3x

133 = 19x

Then divide both sides by 19 to isolate x

133/19 = 19x/19

133/19 = 7, so x = 7

Hope this helps!!
