Answer:
x = -3
y = 9
Step-by-step explanation:
Add two equations up
4x + 5y - 9x - 5y = 33 - 18 add or subtract like terms
-5x = 15 divide both sides by -5
x = -3 we can use this information to find the value of y
4x + 5y = 33 replace x with -3
4 * (-3) + 5y = 33
-12 + 5y = 33 add 12 to both sides
5y = 45 divide both sides by 5
y = 9
Answer:
8.66
Step-by-step explanation:
If it helps, volume is LENGTH x WIDTH x HEIGHT, and for a triangular prism, each side is the same. :)
The function best models the linear relationship is y=12,000x+40,000.
Answer:
x=-7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x−4=3+8x
7x+−4=3+8x
7x−4=8x+3
Step 2: Subtract 8x from both sides.
7x−4−8x=8x+3−8x
−x−4=3
Step 3: Add 4 to both sides.
−x−4+4=3+4
−x=7
Step 4: Divide both sides by -1.
−x/−1=7/−1
x=−7
Answer:
in this for 8 times 7 is 56 and 42 is for 6 times 7
Step-by-step explanation:
there are 7 days as one week so every 8 days would be 1 week and an extra day while six days is almost a week so every 6 days times 7 is 42 while 8 times 7 is 56 than subtract how much of the total number eight days is faster and that 56 for 8 days and 42 for six 56-42=14
