Answer: 12

Step-by-step explanation:

Following PEMDAS, I’ll solve the multiplication first and then add or subtract the values from left to right.

1-2+5-2+5x2

1-2+5-2+10

-1+5-2+10

4-2+10

Answer:

Step-by-step explanation:

You need to use the order of operations, PEMDAS. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

First, multiplication on 5x2 so now it is 1-2+5-2+10.

Next, is addition and subtraction. When it says left to right you are starting with the part of the equation closest to the left, so 1-2=-1. Then add five to get 4. Subtract 2 to get 2. Finally, add 10 to get 12.

Hope you get an A! <3

1/7f- 5 1/2= 9/14. what is f?

Alex777 [14]

To solve this equation, we have to isolate the variable f, or get it alone on one side of the equation.

1/7f - 5 1/2 = 9/14

To do this, we need to add 5 1/2 to both sides of the equation to 1) cancel out the - 5 1/2 on the left side of the equation, and 2) maintain equality both sides of the equation.

1/7f - 5 1/2 + 5 1/2 = 9/14 + 5 1/2

1/7f = 6 2/14

Next, we have to divide both sides by 1/7, to get rid of the coefficient of f on the left side of the equation.

1/7f ÷ 1/7 = 6 2/14 ÷ 1/7

f = 43

Therefore, the the value of f is 43.

Which shows the following expression after the negative exponents have been eliminated? xy^-6/x^-4 y^2, x=/0 y=/0

makvit [3.9K]

The expression would be $\frac{x^5}{y^8}$ after the negative exponents have been removed.

A negative exponent basically tells us to "flip" the side of the fraction it's on. This means that y⁻⁶ on the numerator would go to the denominator, and that x⁻⁴ on the denominator would go to the numerator. This gives us:

$\frac{x\times x^4}{y^2\times y^6}=\frac{x^5}{y^8}$
