Answer:
1,123.30
Step-by-step explanation:
first of all, you are decreasing 1015 by 6 percent so it will be
1015 * 0.93 because you are decreasing it from the percentage
then, you are increasing it by 19 percent so you mulitply what you got on the previous calculation and multiply it by 1.19
943.95 * 1.19
and answer will be 1,123.30
16 1/4 should be your answer.
m=24=+(-9,1,3
3
Step-by-step explanation:
Substitute n=3,\pm 1n=3,±1 into 3m-9n=243m−9n=24
Solve for mm in 3m-(-9,1,3)=243m−(−9,1,3)=24
