Below are the answers:
1. <span>3x = - 12y + 15
3x + 12y = 15 reduces to x + 4y = 5
this matches the other equation, therefore, they are on the same line and have INFINITE SOLUTIONS
2. </span><span>y = 6x + 2
-6x + y = 2
6x - y = -2
3y - 18x = 12
-18x + 3y = 12
18x - 3y = -12 reduces to 6x - y = -4
The equations do not match, therefore, there is NO SOLUTION
3. </span><span>x - 4y = 12
5x - 20y = 60 reduces to x - 4y = 12
same equation, same line, INFINITE SOLUTIONS
4. </span><span>y - 6x = -3
-6x + y = -3
6x - y = 3
4y - 24x = -16
-24x + 4y = -16
24x - 4y = 16 reduces to 6x - y = 4
NO SOLUTIONS</span>
33°≤ t ≤ 35°
Step-by-step explanation:
The body temperature of a bee is given as 35°
When it sleeps, it drops by 2°
The sleeping temperature is therefore : 35°-2°=33°
The rage of body temperature is : 33°-35°
If t is body temperature then the rage in body temperature is;
33°≤ t ≤ 35°

Answer:
30 fl oz
Step-by-step explanation:
1 c = 8 fl oz
5c = 40 fl oz
40 fl oz - 10 fl oz = 30 fl oz
-7 ÷ 2 1/2
Okay, so first, put the -7 over one and make 2 1/2 an improper fraction. so now:
-7/1 ÷ 5/2
Then, take the reciprocal of 5/2 and multiply it by -7/1
-7/1 × 5/2
Which would be -35/2
