Angles B and W are supplementary. Angle B has a measure of (4x+16)˚. Angle W has a measure of 68˚.

What is the value of x?

Answers

the answer is 24 . 180-68= 112 then you -16 soo it would be 96. then you divide by 4 soo 96/4 would be 24 .

Answer:

Step-by-step explanation:

first, set angle b+w=180. You do this because both of the angles added together equals 180°.

Second, begin to isolate the variable.    4x+16 +68= 180

                                                                  4x = 96

                                                                  x = 24

Which of expressions illustrates the associative property?

ab + bc

a ( b + c ) = ab + bc

a ( b + c ) = (a + b ) + c

a + b + c = c + b + a

Answers

Answer:

c)   a ( b + c ) = (a + b ) + c

Step-by-step explanation:

The associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.

Adding negative number is just like adding positive numbers. Just add the numbers like normal and put a negative sign in front of it!

Just think of it as 2.8+3.5

Answer:

The answer is A.-49

number 2 is 0.7

Step-by-step explanation:

Scince they are negative, adding is technically making the number lower, so

-16+-33=-49

2. Is 0.7 because if you convert 2 and 8/10 into decimal form it's 2.8

So 2.8 plus -3.5 is 0.7

A rectangle has a length that is unknown but is 12 inches longer than its width, w. The perimeter of the rectangle is 104 inches.
(a) Write an expression for the length of the rectangle in terms of w. Label it on the diagram. (b) Write an equation using the perimeter to find the value of w. Solve it for w.

Answers

Answer:

[tex]2w+2(w+12)=P (104)[/tex] and [tex]w=20[/tex]

Step-by-step explanation:

We know that the following equation represents the problem:

[tex]2w+2(w+12)= P[/tex]

So this means that we can do this:

[tex]4w+24= P[/tex]

We know that [tex]P[/tex] is 104. We need to fix our current equation, giving us:

[tex]4w+24=104[/tex]

We can subtract 24 to give us [tex]w[/tex] as a standalone with a coefficient.

[tex]104-24=80[/tex]

[tex]4w=80[/tex]

Then, simply divide the answer by the coefficient to give us the answer of:

[tex]80/4=20\\[/tex]

[tex]w=20[/tex]

[tex]w[/tex] is 20.

I think the answer is 20
