None of the choices you provided are correct. Did you type in the question wrong?
Answer:
800,000,000
Step-by-step explanation:
Subtract the known numbers from the sum to find the missing number:
800,903,402 - 900,000 -2 -3,000 -400 = 800,000,000
The answer is is 12.
You can calculate this by multiplying the whole number (in this case, 48) with the percentage (in this case, 25%.)
You would multiply them like this:
48 times 0.25
You put the 0. In the front of the 25 because this is a fraction and a percent.
Hope that helps!!!
3x+5<-22
Subtract 5 from both sides
3x < -27
Divide 3 on both sides
Final Answer: x < -9
