Answer:

A complete angle is one which measures 360∘360∘.

The three angles

6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘

add up to 360∘360∘, as per the question.

6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘

⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘

⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘

⟹2x+3y+z=90∘⟹2x+3y+z=90∘

This is the required relation.

The sides of a rectangle are 3t - 2 and 5t + 7. Write an expression for the perimeter of the rectangle.

natka813 [3]

How does this have anything to do with factoring?
Perimeter of the rectangle would just be 2(3t-2)+2(5t+7)
Simplify that to get 6t-4+10t+14, then 16t+10

Julio and David were in Target and decided to check out the clearance section. They found pencils and erasers that were on sale

Sati [7]

Answer:

Cost of one pencil: $\$0.07$

Cost of one eraser: $\$0.03$

Step-by-step explanation:

Let be "p" the cost in dollars of one pencil and "e" the cost in dollars of one eraser.

Based on the information given in the exercise, you can set up the following system of equations:

$\left \{ {{4p+3e=0.37} \atop {3p+4e=0.33 }} \right.$

You can use the Elimination Method to solve the system of equations.

Multiply the first equation by -3 ad the second one by 4. Then add the equations and solve for "e":

{ $\left \{ {{-12p-9e=-1.11} \atop {12p+16e=1.32}} \right.\\..........................\\7e=0.21\\\\e=0.03$

Substitute the value of "e" into any original equation and solve for "p":

$4p+3(0.03)=0.37\\\\p=\frac{0.28}{4}\\\\p=0.07$
