Answer:
Step-by-step explanation: 20x+15(160-x)=2625
20x+2400-15x=2625
5x=225
x=45
160-x=115
rate of first mechanic= $45/hr
rate of second mechanic=$115/hr
To find the correct fraction, multiply 6 by 3.
This gives you 18. Therefore the fraction is 18/3
Hope this helps!
Well there similar because your adding 10 more or 10× since from ones to the tens is 10×
51/2x-7=62
- Multiply both sides by 2x-7
×(2x-7) = 62(2x-7)
2. Switch sides
62(2x-7) = 51
3. Divide each side by 62
=
4. Simplify
2x-7 = 51/62
5. Add 7 on both sides
2x-7+7 = (51/62)+7
6. Simplify
2x = 485/62
7. Divide both sides by 2
2x/2= 485/62/2
x= 485/124
Answer:
7880
Step-by-step explanation:
If A is S then S is A so using Trin's method...you can find 18x*760+y
