E - English homework, M - Math homework;
M + E ≤ 2 hours
M = 2 E
2 E + E ≤ 2 hours
3 E ≤ 2 hours = 120 minutes
E ≤ 120 : 3
E ≤ 40 minutes
Answer:
The student will be able to finish his English homework in less or equal to 40 minutes.
Answer:
x = 10/3
Step-by-step explanation:
1.Arrange both equations so that the constant is isolated
3x - 2y = 14
6x + y = 18
2. Multiply both sides of first equation by a value that will cancel out a variable when added to the second equation
(-2) 3x - 2y = 14 (-2)
-6x + 4y = -28
3. Add both equations together
-6x + 4y = -28
<u>+ 6x + y = 18</u>
0x + 5y = -10
4. Simplify
5y = -10
y = -2
5. Substitute y-value into one of the original equations to solve for x
3x = 2y + 14
3x = 2(-2) + 14
3x = -4 + 14
3x = 10
x = 10/3

Recall that
. So if
, we can multiply both sides of the equation by
to get





Answer:4 is the answer
Step-by-step explanation:
Answer:
No inequality given but in my view answer is:
x ≥ 16
Step-by-step explanation:
Given that:
Total time = 6 hours
Remaining Time = 6 - 2 hours = 4 hours (40*6 =240 mins)
Time required for 1 centerpiece = 15 mins
We have to find inequality for x:
Number of centerpieces she makes = x
In 240 mins : 240/15 centerpieces can be made
= 16 centerpieces
If she works with the same speed or more efficiently the suitable inequality would be:
x ≥ 16
I hope it will help you!
