Answer:
more the letter x is often used in algebra to mean a value that is not yet known is is calld a variable or sometimes an unknown. in x+2=7,x is a variable but we can work out its value if we try
Answer: choice C) -15x^4y
-----------------------------------------
Explanation:
The coefficients are -3 and 5. They are the numbers to the left of the variable terms
Multiply the coefficients to get -3*5 = -15. So -15 is the coefficient in the answer
Multiply the x terms to get x^3 times x = x^(3+1) = x^4. Notice the exponents are being added
Do the same for the y terms as well: y^2 times y^(-1) = y^(2+(-1)) = y^(2-1) = y^1 = y
So we have a final coefficient of -15, the x terms simplify to x^4 and the y terms simplify to just y
Put this all together and we end up with -15x^4y which is what choice C is showing
Answer: D
Step-by-step explanation: I said D because it's bigger than every other thing
Answer : If you mean this: 1/(3TR) = UV
Then the answer is : 1 = 3TRUV
Answer:
5 x 9 = 45
Step-by-step explanation:
A good way to estimate this would be rounding to the nearest whole number.
First we'll look at 4.73. If we're rounding to the nearest whole number, then that means we'll look at the digit one place to the right of 4. The digit to the right of 4 is 7. 7 is greater than 5 so we round up. We get 5. If we do the same for the other number we see that it also gets rounded up to 9. So our new equation is: 5 x 9. That is a simple multiplication equation and when we multiply we get 45.
Hope this helped!
