Answer:
Step-by-step explanation:
5x + 1 = 4y + 7
5x - 4y = 7 - 1
-4y = -5x + 6
-4y/-4 = -5x/-4 + 6/-4
y = 5/4x - 6/4
y = 5/4x - 3/2
So to make an equation you will have to do $10.50x=147,and then all you have to do is divide 147 by 10.50 to get the number of hours worked. OR 14 hours
Step-by-step explanation:
3/5 of a kilometre
=3/5×1000 meters
=3000/5 meters
=600 meters
Answer:
460/11, rounded to 41.8
Step-by-step explanation:
Let's say that our number is x. The first part states that we decrease 3/4 of a number by 18. Therefore, we find (3/4) of x and subtract that by 18, or (3/4)x-18. That is then equal to increasing (1/5) of x by 5, or (1/5)x+5. Our equation is then (3/4)x-18=(1/5)x + 5.
Adding 18 to both sides, we get (3/4)x = (1/5)x + 23.
Multiplying both sides by 5 and 4 (or 20 as a whole) to remove the denominators, we get that 15x=4x + 460. Subtracting both sides by 4x, we get that 11x=460, and dividing both sides by 11, our answer is rounded to 41.8 (or just 460/11)
