Answer:
79
Step-by-step explanation:
equation:
18x - 8 + 11x = 20x +19
Add like terms:
29x - 8 = 20x + 19
add 8 to both sides:
29x = 20x + 27
subtract 20x from btoh side:
9x = 27
Divide both sides by 9:
x = 3
substitute x into the equation for SU
SU = 20(3) + 19
Solve:
SU = 79
Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)
