Answer:
x=10/c
Step-by-step explanation:
3(cx-7)=9
(cx-7)=3
cx=10
x=10/c
4x+ 3 = 3(2x-5) ;x=2; x^{2} = 4
Answer:
x=18
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(1
/2
)x−7 = (1
/3
)x−4 (Distribute)
Step 2: Subtract 1/3x from both sides.
(1
/6)
x−7=−4
Step 3: Add 7 to both sides.
(1
/6
)x=3
Step 4: Multiply both sides by 6.
x=18
42 is the answer
Explanation:
50% of 80 is half of 80 which is 40
Then you would add 40 with 5% of 40
What you would do then is 5% times 40 then you would change the 5% into a decimal which is 0.05 and multiply it by 40 , which would get u 2
Then you would add the price with tax
40+2 = 42
Answer:
-2(2x-4) = -4x+8 or 2(2x-4) ≠ 4x ; -4x+8 ≠ 4x
Step-by-step explanation:
Did you accidentally write =4x after your expression? If so, then let me explain why my answer is correct. I used distributive property of multiplication, so I multiplied -2 with 2x to get -4x, and -2 multiplied with -4 to get 8. So my final answer was -4x+8. If you did not accidentally put -4x, then my answer would be, 2(2x-4) ≠ 4x or -4x+8 ≠ 4x. Hope this helped.
