Answer:
60(a+b) means that you would have to distribute
While 60a+ 60b is already in it's simplest form
Answer:
1246153597650
Step-by-step explanation:
3x + y = 18
2x - y = 12
we must make both equations have only one variable
we first add the equations top to bottom, and get
5x = 30
we then divide by 5, and get x = 6
now we sub 6 in for x, and solve for y
3x + y = 18 y = 18 - 3x
y = 18 -18
y = 0
the first number is 6, the second number is 0
Is your test online or on paper? how would you show work. i’ll comment the answer on this
The answer to this question would be: 750ft
In this question, you are given the rectangle perimeter (2,000 ft) and the ratio of rectangle length:width (3:1). The equation of this question should be:
3*rectangle width = 1 *rectangle length
rectangle width = 1/3 rectangle length
rectangle perimeter = 2,000ft
Then using the rectangle formula, you will be able to find the length. It would be:
rectangle perimeter = 2* (length+width)
2,000ft /2 = 1/3 length + length
1 1/3 length= 1,000ft
length = 1,000ft /4 *3= 750ft
