To check if x = 9 is the solution, we need to replace every x with 9 and simplify
(3+x)/4 = 3
(3+9)/4 = 3
12/4 = 3
3 = 3
We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.
Answer:
Here is your answer.
Step-by-step explanation:
Sum: -10
Expression:
X = 2
m = -5
(multiplying X and M)
XM = -10 (X times M = -10) (-10 = negative 10)
Hello there!
If DEF = 18, we then use the sin method, or the law of sin.
18 divide by sin90 would be F = sin45 .
We therefore end up with 12.72 but rounded would be 12.7 as 2 is lower than 5, so, it just rounds back down to 7.
Your answer: 12.7
20% because:
rate of Increase = ( final - initial ) / initial * 100
rate of increase = ( 12 - 10 ) / 10 * 100
rate of Increase = 2 / 10 * 100
rate of Increase = 20
