He must've left you. My sincere apologies.
Hey!
--------------------------------
Solution #1:
x - 12 = 4
x + (-12) = 4
x + (-12) + 12 = 4 + 12
x = 16 ✔
--------------------------------
Solution #2:
x - 1/2 = 4
x + (-1/2) = 4
x + (-1/2) + 1/2 = 4 + 1/2
x = 4 1/2 ✔
--------------------------------
Solution #3:
x - 1.2 = 4
x + (-1.2) = 4
x + (-1.2) + 1.2 = 4 + 1.2
x = 5.2 ✔
--------------------------------
Hope This Helped! Good Luck!
Answer:
also got 136 its right
Step-by-step explanation:
Answer: 15,000 meters
Step-by-step explanation:
When measuring the difference in elevations between a body that is above sea level and one that is below, you simply take the distances of the bodies above and below sea level and add it up.
From sea level to Mount Ojos is 6,900 meters. Atacama trench is 8,100 meters below. From the peak of Mount Ojos to sea level is 6,900 meters. Then add the distance from sea level to Atacama to find the difference in elevations.
= 6,900 + 8,100
= 15,000 meters
Part A)
From equation (1) the value of y comes out to be:
y = 4x - 15
Using this value, in equation 2, we get:
5x + 3(4x-15) = 40
5x + 12x - 45 = 40
17x = 85
x = 5
y = 4x - 15
⇒
y = 4(4) - 15
y = 20 - 15
y = 5
Therefore, the solution set to the given equations is (4, 5)
Part B)
The graph of the lines intersect at one point, so they have a unique solution.(First option is correct)
