Answer:
1.4*40=56cm, DVD’s he has
1.4*3=4.2cm
56+4.2=60.2cm, whoops too much. So instead 1.4*2= 2.8cm, 56+2.8=58.8cm Is Your Answer.
Answer:
Step-by-step explanation:
6x + 3y = 3 simplify by dividing both sides by 3 2x + y = 1
3x - y = 4 the 1st equation has a positive y, the 2nd has a negative y. Use elimination
to reduce them down to a single variable equation:
2x + y = 1
3x - y = 4
________
5x = 5 solve
X = 1 substitute back in to one of the original equations to find y
3x - y = 4
3(1) - y = 4
- y = 1
y = -1 (1,-1)
-7t+3>-46
Subtract 3 on both sides to cancel it out.
-7t+3>-46
-3 -3
-7t>-49
Now divide -7 on both sides.
-7t>-49
/-7 /-7
t>7
This means the answer, or t, can be anything above 7.
