The correct answer is the last choice, the scenario about the paint brushes.
In this scenario x stands for the number of packs of five paintbrushes, and y stands for the number of packs of three paint brushes. This is shown in the first equation.
x plus y will give us 60 total packs of paint brushes which is shown in the second equation.
Answer:
van=18
bus=59
Step-by-step explanation:
Let v=van & b=bus
1v+6b=372
1v=372-6b
4v+12b=780
Lets divide by 4
1v+3b=195
then
1v=195-3b
substitute in first expression
372-6b=195-3b
simplify
177=3b
b=59
then substitute
1v=195-3(59)
1V=18
Answer:
5 times
Step-by-step explanation:
Given the multiplication problem :
5 * 1 /3 = (5*1) / 3 = 5/3
The number of times 1/3 will. Have to be added to itself to obtain 5/3.
To do this :
5/ 3 ÷ 1/3
5/3 * 3/1
= (5*3) / (3*1)
= 15 / 3
= 5
Hence, 1/3 will have to be added 5 times to itself
The slope is (9-7)(4-(-2)) = 2/6 = 1/3;

The correct anwer for the last question is b).
Answer:
-20x^4y + 40x^3y^2.
Step-by-step explanation:
-5x^3y(4x-8y)
= -5x^3y * 4x + -5x^3y * -8y
= -20x^4y + 40x^3y^2
