4x+6+3=17
4x+9(add the 6 and 3)=17
4x=8(subtract 9 from each side 4x+9-9=17-9)
x=2(divide each side by 4, 4x/4=8/4)
2 is the final answer.
You can check your work...
4(2)+6+3=17
8+6+3=17
14+3=17
17=17
So this is correct!!! Hope this helps you.
Answer:
J = 32
E = 0
Step-by-step explanation:
E is the number of hours for the Escobar family
J is the number of hours for the Johnson family
E + J = 32
E * 20 + J * 30 = 960
Multiply the first equation by -20 so we can use elimination
-20 E -20 J = -640
Add this to the second equation
E * 20 + J * 30 = 960
-20 E -20 J = -640
---------------------------------
10 J = 320
Divide by 10
J = 32
Now find E
E + J = 32
E + 32 = 32
E = 0
To determine this easily, figure out what two numbers will make a product ending with "2", (4 & 3, 8 & 9)
Since the square root of 625 is 25, it is obviously less than 25.
I used 18 and 19, and they are the correct answer.

Answer:
2/3, 5/7, 16/12
From least to greatest!
Smallest = 2/3, Second = 5/7, Largest = 16/12
Hope this helped :-)
