Assume
if |a|=b
a=b and -a=b
so
9|9-8x|=2x+3
divide both sides by 9
|9-8x|=2/9x+1/3
assume
9-8x=2/9x+1/3 and
-9+8x=2/9x+1/3
9-8x=2/9x+1/3
times 9 both sides
81-72x=2x+3
add 72x both sides
81=74x+3
minus 3
78=74x
divide both sides by 74
39/37=x
other one
-9+8x=2/9x+1/3
multiply both sides by 9
-81+72x=2x+3
minus 2x both sides
-81+70x=3
add 81 to both sides
70x=84
divide boh sides by 70
x=6/5
x=39/37 and 6/5
check
9|9-8(39/37)|=2(39/37)+3
2646/37=189/37
false
9|9-8(6/5)|=2(6/5)+3
351/5=27/5
false
no soltion evidently, weird
Answer:
4.5
Step-by-step explanation:
if we take -1 and put it in L.H.S it becomes 8+1=9 and then when u put x2 which is x×2 to L.H.S it becomes 9÷2 =4.5
Im assuming the rest of your question is: how much was collected for children? if thats the case your answer will be this;
1000×4=4000 (adult total in admission)
5050-4000=1050 (children total in admission)
1050÷1.50=700 (kids went to the fair.)
We are required to find the total hours David and Xavier works in a week
The total hours David and Xavier works in a week is 70 hours
let
number of hours Xavier works = 32 hours
number of hours David works = (6 + 32) hours
= 38 hours
<em>Total number of hours David and Xavier works in a week = number of hours Xavier works + number of hours David works</em>
= 32 hours + 38 hours
= 70 hours
Therefore, the total hours David and Xavier works in a week is 70 hours
