A proportion is an equation stating that 2 ratios are equal. One example of using them is in baking. An example of one would be:
Answer:
n=4
Step-by-step explanation:
step 1: Simplify both sides of the equation.
4n−1=6n+8−8n+15
4n+−1=6n+8+−8n+15
4n−1=(6n+−8n)+(8+15)(Combine Like Terms)
4n−1=−2n+23
4n−1=−2n+23
Step 2: Add 2n to both sides.
4n−1+2n=−2n+23+2n
6n−1=23
Step 3: Add 1 to both sides.
6n−1+1=23+1
6n=24
Step 4: Divide both sides by 6.
6n/6=24/6
Answer:
(a, a+b).
Step-by-step explanation:
Midpoint = [(a+2b + a-2b)/2 ], [b-a + 3a+b]/2
= (2a/2, (2a+2b)/2
= (a, a+b).
<span>9x − 2 = 4(x + 3)
Use PEMDAS
9x - 2 = 4(x + 3)
9x - 2 = 4x + 12
add 2 to both sides
9x = 4x + 14
subtract 4x from both sides
5x = 14
divide both sides by 5
x = 14/5
x = 2 4/5
Hope this helps!
