Step-by-step explanation:
(2x-18)+(4x)=180 bc its a straight line
simplify
6x-18=180
-18 -18
6x=162
divide
x=27
Answer:
35 times
Step-by-step explanation:
Since the ratio of goals to misses are 6:5
Your ratio would be
5/6 = 42/x
Let's cross multiply
42×5 is 210
divide 210 by 6 and you'll get 35
She missed 35 times.
We will express the work done relative to time thus,
person a = 1/4
person b = 1/6
Since two of them will work together and then add the two.
total work = person a + person b
= 1/4+1/6
=(3+2)/12
=5/12 hours
in hours
1/t=5/12 hours
total time = 2.4 hours or 2 hours and 24 mins.
The total time that person a and person b when working together will make the work done in 2.4 hours.
No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5. Since the class must wash a whole number of cars, they need to wash at least 38 cars.
