-26n -22= n - 90
-26 times a number: -26n
minus 22: -22
equal: =
90 less than a number: n - 90
Solving the Equation:
Move n to the left side of the equal sign (which becomes -n) in order to combine like terms:
-26n-n-22= -90
Move -22 to the right side of the equal sign which becomes +22
-26n-n=-90+22
solve both sides; -26n-n= -27n and -90+ 22= -78
-27n=-78
n= 2.888888
Answer:
A) x = 15
Step-by-step explanation:
4x - 30 = 2x
subtract 2x from each side of the equation:
2x - 30 = 0
add 30 to each side:
2x = 30
x = 15
4 thousands equals 40 hundreds.
The first one will flash at every 30 sec and the second one at 20 sec. The second one will go like 1- 4- 8 and then to 12. By the time the second one will reach first at 6 and then on 12. So, after every 1 minute they will flash together.
Answer:
x < -3/2
Step-by-step explanation:
12x + 7 < -11
Subtract 7 to both sides
12x < -11 -7
= 12x < -18
Solve for x.
x < -18/12
= x < -3/2
