X-1.5=5.25
X=5.25+1.5
X=6.75
The initial elevation of the plane is 6.75 miles
Hope it helps!
Answer: 
Explanation:
Place the decimal point between the first two digits to get 4.14
Now ask yourself: How many places must we move the decimal point to go from 4.14 back to 4,140,000,000?
The answer is 9 places to the right.
This means we'll have 9 as the exponent over the 10
Answer:
no solution
Step-by-step explanation:
Suppose the system equations are:
y = (-1/4)x + 2 (1)
3y = (-3/4)x – 6 (2)
If we multiply equation (1) by 3:
3y = (-3/4)x + 6 (1)
3y = (-3/4)x – 6 (2)
then subtract it from equation (2):
0y = 0x – 12
0 = -12
This is not possible, therefore, the system equation has no solution
The answer is C because 2, 5, 23, and 29 are prime numbers (you can also look up a chart and highlighted numbers are prime). prime numbers is a whole number greater than 1 and cannot be formed when multiplying two smaller numbers that are whole. it must involve itself in a multiplication equation.
We can express an equation to find the fraction of the catering order that is sandwiches or salads by summing up the fractions of the sandwiches and the salads, in this case, the fraction of the sandwiches is 5/12 and the fraction of the salads is 2/12, then the equation looks like this:
c = 5/12 + 2/12, option B is the correct answer
