it looks good!
Step-by-step explanation:
The perimeter is 76 but i don’t remember how to find the area
Use cymath it gives you the math answers but the answer is x=74
Answer:
x = 30
Step-by-step explanation:
10% fat = 0.1x
x = the solution, what we want to find
120 grams of 20% fat = 0.2 * 120
What we want is mixture of 18%
So....
0.1x + 0.2 * 120 = 0.18 (x + 120)
Solve:
0.1x + 24 = 0.18 (x +120)
0.1x + 24 = 0.18x + 21.6
24 = 0.08x + 21.6
x = 30
Answer:
-1
Step-by-step explanation:
Given the equation :
2(3x – 1) > 4x – 6
Open the bracket :
6x - 2 > 4x - 6
Collect like terms
6x - 4x > - 6 + 2
2x > - 4
Divide both sides by 2
2x /2 > - 4/2
x > - 2
Since x > - 2
-10, - 5, - 3 are all < - 2
Hence, the only option greater than - 2 is - 1
