Answer:
Step-by-step explanation:
7x - 6 = 12 - 2x
9x - 6 = 12
9x = 18
x = 2
7(2) - 6 = 14 - 6 = 8 AB
12 - 2(2) = 12 - 4 = 8 BC
8 + 8 = 16 AC
Answer:
5 times
11.50
plz give brainiest
Step-by-step explanation:
50+2x=100
-50 -50(subtract 50 from both sides)
2x=50 (divide both sides by 2)
x=25
Answer:
8(x+4)x(x-7)
Step-by-step explanation:
hope this helps!
7x - y= -5. Standard form is when it is written with x and y on the same side, but x is not negative or a fraction. To find the slope and y intercept, you must change the first two equations to slope intercept. You get y=7x-5 for the first one and y=11/3x+5 for the seccond equation. Take the 5 as your y intercept and the 7 as your slope and you get y=7x+5. Now you need to change it into standard form. When all is said and done, your final answer should be 7x - y = -5.
