Answer:
Step-by-step explanation:
it will always be true as long as it is adittion the r is the unknown number just add 15 plus what equals 25
Let's solve for f.
y=f−1x
Step 1: Flip the equation.
f−x=y
Step 2: Add x to both sides.
f−x+x=y+x
f=x+y
Answer:
f=x+y
Answer:
n = 1
Step-by-step explanation:
Add 20 to both sides, obtaining
n = 4 - 3n
Next, add 3n to both sides:
4n = 4
Finally, solve for n by dividing both sides by 4:
n = 1
5(7x - 15) + 2x ≥ 13x - 3 <em>multiplied both sides by 2 to clear the denominator</em>
35x - 75 + 2x ≥ 13 x - 3 <em>distributed 5 into 7x-15</em>
37x - 75 ≥ 13x - 3 <em>added like terms (35x and 2x)</em>
24x - 75 ≥ -3 <em>subtracted 13x from both sides</em>
24x ≥ 72 <em>added 75 to both sides</em>
x ≥ 3 <em>divided both sides by 24</em>
Answer: x ≥ 3 Notation: [3, ∞)
