Answer:
32/243
Step-by-step explanation:
do 2 to the 5th and put it above 3 to the 5th
Okay so for this one, we have to isolate our X.Lets start by moving the negative 5 on the other side of the equal sign. Remember to not mix a number that is with an X with a normal number (in this case it would be the -3x and the -5). So in putting our -5 on the other sign it becomes positive. Here’s what we have: x^2-3x=5. x^2 is the same thing as 2x.So now you have to minus 3x off of your 2x. This gives us -1x, but can just be put as -x. So now we have -x=5. You’re answer could either be 5 or -5 if you decided to divide it by -1 seeing as your -x is technically -1.
Answer:
112.34
Step-by-step explanation:
The 2nd digit after the decimal point is in the hundredths position.
• If the digit following is ≥ 5 then round up
• If the digit following is < 5 then leave digit as it is
here the digit following the 3 in the hundredths position is 9 so round up
112.3398 ≈ 112.34 ( to the nearest hundredth )
1 yard = 3 feet
2/3 of a yard would be 2 feet
4.5 yards = 13.5 feet
13.5-2 = 11.5 feet
11.5 feet = 3.83 yards
therefore at least 11.5 feet or 3.83 yards must be purchased
