Answer:

(2x+2)

=98

(x+34)

=82

Step-by-step explanation:

a straight line adds up to 180

(2x+2)+(x+34)=180

x+2+x+34=180

(2x+x)+(2+34)=180(Combine Like Terms)

3x+36=180

Step 2: Subtract 36 from both sides.

3x+36−36=180−36

3x=144

Step 3: Divide both sides by 3.

3x/3=144/3

x=48

Now you have your x just substitute it in

(2x+2)

=98

(x+34)

=82

Which of the following expressions are equivalent to 6.53 - (-4.11) + 7.926.53?

umka21 [38]

Answer:

Choice B and Choise C.

Step-by-step explanation:

Equivalent expressions are those expressions that have the same value but they look different.

Given the following expression provided in the exercise:

$6.53 - (-4.11) + 7.92$

You need to remember the multiplication of signs in order to find the equivalent expressions:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

Then:

- Eliminating the parentheses, you get this equivalent expression:

$6.53 +4.11 + 7.92$

- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:

$-(-6.53)+4.11-(-7.92)$

This is an equivalent expression to $6.53 - (-4.11) + 7.92$

Heyyy ummm... help??

atroni [7]

The statements true for the given function are:

$f(0) = \frac{3}{2}$
$f(4) = \frac{7}{2}$

I tried them all and these two were correct, their solutions are as follows:

= f(x) = 1/2x + 3/2

= f(0) = 1/2 × 0 + 3/2

= f(0) = 0 + 3/2

= f(0) = 3/2

= f(x) = 1/2x + 3/2

= f(4) = 1/2 × 4 + 3/2

= f(4) = 2 + 3/2

= f(4) = 4+3/2

= f(4) = 7/2

So, that's how these two are correct.

A puzzle contains a triangular piece with a base of 3 in. and a height of 4 in. A manufacturer wants to make 80 puzzles. Find th

kari74 [83]

Since the base is 3 inches and the height is 4 inches, as well as the area of a triangle being base*height/2, we get 3*4/2=6 in. for each triangle. Since we need 20 pieces for each puzzle, we multiply 6 by 20 to get 120. In addition, since 80 puzzles are needed, with 20 pieces for each puzzle, we have 120 inches for each puzzle and 120*80 = 9600 square inches of wood used
