Answer:
140
Step-by-step explanation:
70% 200
---------- * ---------- = 70*2 = 140
100% 1
you cross out the 2 zeros from the 100% so it will be one then croos out the 2 zeros from 200 and you will have 70 * 2 and you will get 140
X=10.5
8/6=14/x
Cross multiply
8x=84
Divide 8 to both sides
X=10.5
1.y= 3x+ 19
2. y= 4x+10
3. y= 7x+-5
