Step-by-step explanation:
The denominator cannot be zero, so x cannot be 6.
Answer:a) 15,315
b) 1005
Step-by-step explanation: shown in the attachment
Step-by-step explanation:
Given that,
a + 2b = 17
Also,
2a + b = 4
By adding the above expressions we get,
a + 2b + 2a + b = 17 + 4
3a + 3b = 21.
3 (a + b) = 21
a + b = 21/3
a + b = 7 Let us take 'b' = 10
a + 10 = 7
a = 7 - 10
a = -3
Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions
a + 2b = 17
-3 + (2 × 10) = 17
-3 + 20 = 17
17 = 17
2a + b = 4
(2 × -3) + 10 = 4
-6 + 10 = 4
4 = 4
Therefore, a = -3 and b = 10 [(-3,10)] is the solution.
We can use the distance = rate times time formula.
This formula states that if you travel at a constant rate for a certain amount of time, you will know the distance that you traveled.
We know the rate is 3 mph and she hiked for 6 hours.
distance = 3 * 6
distance = 18
So, she traveled 18 miles.
Answer:
Step-by-step explanation:
1 package contains 16 slices. A dozen packages is 12 packages. Therefore, a dozen packages will contain 16×12 slices which is 192 slices.
