Stephen purchased a guitar, which was originally priced at $80 but discounted at 25%. He also had to pay 5% sales tax. What amount did Stephen pay to purchase the guitar?
Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.

There were some pizzas in the library. 13 pizzas were eaten by zombies. There are now 20 pizzas in the library. Which equation can be used to find p, the number of pizzas that were in the library?
Answer:
p - 13 = 20
Step-by-step explanation:
p - 13 = 20
add 13 on both sides
p = 33
there were 33 pizzas in the library.
Answer:
p=13+20? or addition
Step-by-step explanation:its inverse operation i think that's what its called so use addition
\begin{aligned} &-x+4y=-9 \\\\ &y=-2x +6 \end{aligned} −x+4y=−9 y=−2x+6 Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
Answer:
NO
Step-by-step explanation:
Given the system of equation
-x+4y = -9,... 1
y = -2x+6.... 2
To find the solution to the equation
Substitute equation 2 into 1
-x+4(-2x+6) = -9
-x-8x+24 = -9
-9x= -9-24
-9x = -33
x = 33/9
Find y
y = -2x+6
y = -2(33/9)+6
y = -66/9 + 6
y = -66+54/9
y = -12/9
y = -4/3
Hence (2,3) is not the solution to the system of equation
He math team does practice drills that each last hour. In February the team did practice drills for a total of 24 hours. How many practice drills did the math team do in feburary
Answer: 24 drills
Step-by-step explanation:

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
Answer:
We can make the paint amount equal by making sure the parameters have the same unit
Step-by-step explanation:
Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
To solve the above question, we have the conversion rate:
We can make the paint amount equal by making sure the parameters have the same unit
Hence:
1 gallon (gal) = 3.785411784 kilogram (kg).
Billy had 5 gallons of paint.
1 gallon (gal) = 3.785411784 kilogram (kg).
5 gallons of paint = x
Cross Multiply
x = 5 × 3.785411784 kg
18.92705892 kilograms of paint
Approximately 18.93 Kilograms of paint
Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint

Please help!!!! Maths!!!!!
Answer:
x= 2 or x= -3
Step-by-step explanation:
Bring the equations together using a common denominator (x-5) (x+7)
x-29/(x-5) (x+7)= 1
Multiply both sides by (x-5) (x+7)
x- 29= (x-5) (x+7)
x- 29= (x-5) (x+7)= x^2 + 2x - 35
-x^2 - x + 6 = 0
-(x-2)(x+3)= 0
Multiply both sides by -1
(x-2)(x+3)= 0
Split it into two equations
x-2= 0 or x+3= 0
x= 2 or x= -3
Find the height of a triangle whose base is 5 inches and area is 12 square inches.
Answer:
Therefore, Height = 4.8 inches.
Step-by-step explanation:
Given : A triangle whose base is 5 inches and area is 12 square inches.
To find : Find the height of a triangle.
Solution : we have given
Triangle base = 5 inches.
Area = 12 square in.
We need to find height of the triangle.
Area = * base * height .
Plugging the values .
12 = * 5 * height .
On multiplying both sides by 2
24 = 5 * height .
On dividing both sides by 5.
Height = 4.8 inches.
Therefore, Height = 4.8 inches.
