x = 7

Step-by-step explanation:

( x +16)° = (4x - 5)°

16 + 5 = 4x - x

A store pays $10.56 fora map of Africa and marks the price up by

nignag [31]

Essentially, 50% of $10.56 is $5.28.

This means that all we have to do is add $10.56 to $5.28, making $15.84

Side note: Another way that you can do this is by simply doing 1.5(10.56).

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":

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