Step-by-step explanation:
D) 39 kg
Answer:
Ans= (-9,-5)
Step-by-step explanation:
- 10x + 3y = 5.....equation (1)
x = y - 4.....equn(2)
put equation2 in equation 1
- 10(y-4)+3y=5
open the bracket
-10y + 40 +3y =5
-40 -40
-10y+3y= -35
-7y=35
divide by -7
y= -5
put y in equation 2
x=y-4
x=-5-4
x= -9
solution= -9,-5
Answer:
For question 4 the answer would be B.
For question 6 the answer would be D.
Step-by-step explanation:
<span>-49 + -2x + 12x = 101 + -12x + 12x Combine like terms: -2x + 12x = 10x -49 + 10x ... 101 + 49 = 150 10x = 150 Divide each side by '10'. x = 15 Simplifying x = 15 </span><span>
