1) Let's evaluate that expression
3x+5
2) Since the value of x has been given, then let's plug that into the expression
3x+5
3(5) +5
15 +5
20
3) The answer is 20
Answer:
boys = 705
girls = 783
Step-by-step explanation:
We are to find the number of boys and girls in the school
the answer can be determined using simultaneous equation
x = boys
y = girls
y - x = 78 equation 1
y + x = 1488 equation 2
subtract equation 1 from 2
2x = 1410
x = 1410/2 = 705
Substitute for x in equation 1
y - 705 = 78
y = 705 + 78 = 783
1. -3
2. 28
3. 88
4. -5
5. -28
First, you would start on the orgin (0,0), and move up 1. You should now be at (1,0) make a point here
Next, you will move down 2. You should now be at (-1,0)
Finally, you move right 3.
You should now be at (-1,3)
Make a point
Hope this helps!
