2,000, 200 and 20 are similar except for the number of zeros.
You can remove a zero from each to equal the number of zeros in the divisor. So 80,000 ÷ 2,000 is equivalent to 80 ÷ 2 = 40 you just remove the 3 zeros
80,000 ÷ 200 is equivalent to 800 ÷ 2 = 400 you just keep removing 0s like for instance this time it was 2 lastly 80,000 ÷ 20 only allows us to remove 1 zero 8,000 ÷ 2 = 4,000. The smaller the divisor the greater the quotient when dividing the same number like for instance in this example 80,000
We have that
y=-2x+3
y=(1/3)x-4

the solution of the system is the point (3,-3)
Answer:30
5x+130=6x+100
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+130=6x+100
Step 1: Subtract 6x from both sides.
5x+130−6x=6x+100−6x
−x+130=100
Step 2: Subtract 130 from both sides.
−x+130−130=100−130
−x=−30
Step 3: Divide both sides by -1.
−x
−1
=
−30
−1
x=30
