son4ous [18]

Answer:

$18

Step-by-step explanation:

Given:

6.4x - 2.1x = 77.4

Where,

x = cost of sheet metal per square foot

How much does sheet metal cost per square foot?

6.4x - 2.1x = 77.4

4.3x = 77.4

Divide both sides by 4.3

x = 77.4 / 4.3

= 18

x = $18

Sheet metal per square foot cost $18

ABC and CBD form a linear pair and have equal measures. Tell if ABC is acute, right, or obtuse

Murrr4er [49]

To form a linear pair means that when added, they equal 180 degrees.
but if they have equal measures....180/2 = 90...then they would both equal 90 degrees.....and 90 degrees is a right angle.
So ABC and CBD are both right angles

Plz, answer! 34 + 2 ⋅ 5 =

8_murik_8 [283]

$3^{4}$ + 2 × 5

To evaluate apply the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

Parentheses

There are none for this steps so go on to the next step

Exponent:

$3^{4}$

so...

81 + 2 × 5

Multiplication:

81 + 2 × 5

2 × 5

so...

81 + 10

No division in this equation so skip this step and go to the next one

Addition:

81 + 10

Hope this helped!
