To find a percentage, you the decimal point in the percent two places to the right 16% = 0.16. Then multiply.
0.16 • 400 = 64
16% of 400 = 64
Step 1: It tells you that x = 4, so replace x with 4 in the equation. 4 + 3y = 16
Step 2: Use the substitution method to subtract 4 from both sides. (4-4) + 3y = (16 - 4) ——> 3y = 12
Step 3: You must now get the variable y alone, so divide 3 to both sides. 3y/3 = 12/3 ——> y = 4
The answer is (4,4)
Answer:
37,500
Step-by-step explanation:
0.2x+0.1(x−0.2x)=105000.2x+0.1(x−0.2x)=10500
0.3x−150x=105000.3x−150x=10500
15x−x50=1050015x−x50=10500
x=10500∗5014=1500∗25=37500
I think the answer is -5k - 10
