Anna saved $30 each month from babysitting for 2.75 years. She spent 75% of her savings on a computer.
How much money did Anna have left?
Answers
Answer:
45.00 is what she has left
Step-by-step explanation:
Anna has $275.5 left after buying computer.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Given that Amount saved by Anna each month = $30
Time period = 2.75 years.
1 year = 12 months
2.75 years = 2.75 years x 12 = 33 months
The Amount saved in 33 months = 33 x 30 = $990
She spent 75% of her savings.
Amount spent = 75% of 990
Amount spent = 75% x 990
Amount spent = $742.5
Amount left = Savings - Amount spent
Amount left = 990- 742.5= $275.5

Peter is given the following equation. What operation should he use to solve for W?
Answers
Answer:
The correct answer is Option 1: multiplication
Step-by-step explanation:
Given equation is:
[tex]20 = \frac{w}{6}[/tex]
Given equation is a linear equation with one variable w. In order to solve the linear equations in one variable, properties of equality are used.
Solving for w means that w has to be isolated on one side of the equation i.e. w should be without a multiple or denominator.
The equation will be multiplied by 6 to remove the denominator in w/6
[tex]20*6 = \frac{w}{6} *6\\w = 120[/tex]
Hence,
The correct answer is Option 1: multiplication

[tex]\displaystyle \frac{a}{-7} - 7 = 5[/tex]
Step 2: Solve for a
Addition Property of Equality: [tex]\displaystyle \frac{a}{-7} - 7 + 7 = 5 + 7[/tex] [Simplify] Add: [tex]\displaystyle \frac{a}{-7}= 12[/tex]Multiplication Property of Equality: [tex]\displaystyle -7 \cdot \frac{a}{-7} = 12 \cdot -7[/tex][Simplify] Multiply: [tex]\displaystyle a = -84[/tex]Step 3: Check
Plug in a into the original equation to verify it's a solution.
Substitute in a: [tex]\displaystyle \frac{-84}{-7} - 7 = 5[/tex][Frac] Divide: [tex]\displaystyle 12 - 7 = 5[/tex]Subtract: [tex]\displaystyle 5 = 5[/tex]Here we see that 5 does indeed equal 5.

Find the value of z in the triangle shown below.
Answers
Answer:
x = 68
Step-by-step explanation:
This is an isosceles triangle meaning that two sides of the triangle are equal in length while one side is not. Because we know that two of the side lengths are equal, we know that their corresponding angles are equal. In this instance, they both will have angles measuring 56°. We know that the sum of the angles of a triangle is equal to 180°. Use this information to set up an equation and solve for x.
x + 56 + 56 = 180
x + 112 = 180
x = 68
