Answer:
A
Step-by-step explanation:
The simpler way to calculate this question is just to calculate A and B
A - 4 x (7+2) = 4 x 9 = 36
B - (4 x 7) + 2 = 28 + 2 = 30
A = 36
=> Thus, our answer is A

Answer:
3 pants and 5 shirts
Step-by-step explanation:
x+y=8
28x+12y=144
-12x-12y=-96
16x=48
x=3
Answer:
Inconsistent
Step-by-step explanation:
We are given the equations;
0.3y=0.6x+0.3
1.2x+0.6=0.6y
Assuming we are required to determine whether the system of equations are consistent or inconsistent
We are going to use substitution
Making y the subject;
Equation 1: 0.3y=0.6x+0.3
Dividing both sides by 0.3
y = 2x + 1
Equation 2: 1.2x+0.6=0.6y
Dividing both sides by 0.6
y = 2x + 1
This means both equations are similar and we can't get a solution.
Therefore, the system of equations is inconsistent.
Answer:
-1 < y < 7
Step-by-step explanation:
< and not ≤
because the end points are not included
hello! your answer would be b: +4 degrees celsius and -2 degrees celsius because the starting temperature was 70 degrees, then heated up four degrees, and then cooled back down 6 degrees.
