-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:
0.625 years = 7.5 months
Step-by-step explanation:
Simple interest formula = rxtxp divided by 100
R x T x P / 100 = 30
Substitute all the values we know
3.2 x T x 1500/100 = 30
Simplify and rearrange =
3.2 x T x 1500 = 3000
3.2 x T = 2
T = 2/3.2
T = 0.625
Answer:
122
Step-by-step explanation:
the real answer is 121.53846153846153, but you wanted to round to nearest percent
B. 3
Here’s why
t1 = 3072, r = -1/2
t11 = 3072 (-1/2)^10 = 3
