Answer:
The answers for the exercise shown in the figure attached above, are shown
Step-by-step explanation:
-The Compound inequality for the solution 1 is:
-2(x+1)≥-4 or 4x-7≥5
x≥1
x≥3
-The Compound inequality for the solution 2 is:
-6≤2x-8≤-2
1≤x≤3
-The Compound inequality for the solution 3 is:
3x-4≥5 or -5x+17≤12
x≥3
x<1
Answer:
Answer:
x + 2y = 2
x - 2y = -2
2x = 0
x = 0
0 + 2y = 2
2y = 2
y = 1
(0, 1)
Step-by-step explanation:
consistent and independent
Hey there!
Answer:
x = 195
Explanation:
So here is your equation:
90 = -105 + x
First, you simplify both sides of the equation:
90 = x - 105
Then, you will have to turn it around:
x - 105 = 90
So after you do that, you will have to Add the 105 to both sides:
x - 105 + 105 = 90 + 105
x = 195
So 195 is your answer.
Hope this helps! :D
Answer:
6.16 hours
Step-by-step explanation:
Let the number of hours that washed the car together = T
Number of hours Matthew washed = m = 14 hours
Number of hours Arianna washed = a = 11 hours
The formula to calculate how many they wash the cars together is given as
1/a + 1/m = 1/T
1/14 + 1/11 = 1/T
Lowest Common Denominator = 154
Hence:
(11 + 14)/154 = 1/T
25/154 = 1/T
Cross Multiply
154 × 1 = 25 × T
T = 154/25
T = 6.16 hours
Therefore, it will take Matthew and Arianna 6.16 hours to wash the cars together
