Answer:

$5x+80=180$
I hope this helps and that you can give a brainliest!

Step-by-step explanation:

This is a straight line which is always 180°.

Here there are 3 angles adding up to the total 180°.

So the initial equation is $3x+80+2x =180$ .

But there are coefficients that share the same variable.
So by simplifying the equation, you end up with:

$5x+80=180$

Manuel made $80 for 5 hours of work.

Virty [35]

Answer:

13 hours

Step-by-step explanation:

Let's first start by finding how much he makes in 1 hours:

$\frac{\$80}{5} =\$16$

Now we can set up two ratios

$\frac{16}{1} = \frac{208}{x}$

Solve by cross multiplying (multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction)

16x=208

Divide both sides by 16 to isolate x

x=13

He would have to work 13 hours to make $208

"Complete the equation " please help ❕❕a 2/3 • a⬜️ = a 5/6

MArishka [77]

A2/3 x ? = a5/6
Divide a2/3 from both sides
? = a5/6 / a2/3
? = a5/6 x a3/2
? = a15/12
? = a1+1/4

Suppose you plan to go out for a picnic during spring break. You plan to bring sandwiches, fruits, and drinks. But you only have

Andreyy89

Answer:

e) z (max) = 24

x₁ = x₂ = 0 x₃ = 4

Step-by-step explanation:

a) The problem requires maximizing the total value from sandwich fruits and drink, therefore the objective function is associated to the sum of the values of each value.

We have three variables xi ( x₁, x₂, x₃ ) the values of sandwich, fruits and drink, and we have to maximize such quantities subject to the constraint of size (the capacity of the basket)

b) z = 6*x₁ + 4*x₂ + 6*x₃ Objective Function

Constraint :

basket capacity 17

9*x₁ + 3*x₂ + 4*x₃ ≤ 17

General constraints:

x₁ ≥ 0 x₂ ≥ 0 x₃ ≥ 0 all integers

e) z (max) = 24

x₁ = x₂ = 0 x₃ = 4

NOTE: Without the information about fractional or decimal feasible solution we decided to use integers solution
