Which best describes the solution to 4 – 7? Because –4 + (–7) is an equivalent expression, the answer is –11. Because 4 + (–7) i
s an equivalent expression, the answer is –3. Because 4 + (–7) is an equivalent expression, the answer is –11. Because –4 + (–7) is an equivalent expression, the answer is –3.
The answer to your question would be: Because 4 + (-7) is an equivalent expression, your answer is -3. The reason for this can be described using integers. So lets say you have $4. You owe your brother $7. Since you don't have enough to pay him, you can pay him all your money, but you still have to pay him $3 more. This means technically your balance is $-3, cause if he needs the money, the second you get it he will ask for it. Sorry if this isn't too great of an example, not sure what else I could think of. Pretty much remember when subtracting a number, you can add the negative of the number, because that is the same thing. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine). Thanks, it really helps! :D
To solve this, we have to find the volume of the cylinder first. The formula to be used is
Given:V= ?r= 6cmh= 10cm Solution: V= (3.14)(6cm) x 10cmV= (3.14)() x 10cmV= () x 10cmV= 1130.4cm^3 Finding the volume of the cylinder, we can now solve what the weight of the oil is. Using the formula of density, Density = mass/volume, we can derive a formula to get the weight. Given:Density = 0.857 gm/cm^3Volume = 1130.4 cm^3 Solution:weight = density x volumew= (0.857 gm/cm^3) (1130.4cm^3)w= 968.7528 gm The weight of the oil is 968.75 gm.
