Answer:
m = 3, n = -2.
Step-by-step explanation:
Substitute n = 3m - 11 in the second equation:
2m + 3(3m - 11) = 0
2m + 9m - 33 = 0
11m = 33
m = 3.
Substitute for m in n = 3m-11:
n = 3(3) - 11
n = -2.
In order to write in scientific notation you have to write an expression with a whole number times 10 to a certain exponent. In this case the nearest whole number would be 7.65 and you have to move the decimal place twice to the left to get the desired number. Thus, the exponent would be a negative number. The final answer is : 7.65 x 10^-2.
23 hundredths = 0.23
9.041 + 0.23 = 9.271
Answer:
Step-by-step explanation:
First you want to do what is in the paratheses which is 3*2 which equals 6
Next do the multiplication and division left to rightwhich is 6*2 which equals 12 and 2*4 which equals 8
Last do your addition and subtraction left to right
12+12-8=16
