Answer:
15
Step-by-step explanation:
5x4=20
5x-1=-5
20-5=15
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.

Answer:
2/3r + p
Step-by-step explanation:
2/3r + 4/3p - 1/3p
combine like terms, terms with like coefficients can be combined, terms that do not have like coefficients cannot be combined
coefficient- the variable that a number is multiplied by
2/3r + <u>4/3p</u> <u> - 1/3p</u>
combine
2/3r + 3/3p
or
2/3r + p
Answer:

Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the measure of a side of the square )
Here s = x + 2 and A = 7, thus
(x + 2)² = 7 ← expand left side using FOIL
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
