Answer:
x = 5
Step-by-step explanation:
5(x + 10) + 2x = 13 + 3(5x - 1)
5x + 50 + 2x = 13 + 15x - 3
7x + 50 = 10 + 15x
50 - 10 = 15x - 7x
40 = 8x
40/8 = x
5 = x
10:40
This ratio is 10/40. Divide both by 10. You will get 1/4. 1/4 is 1:4.
So, we have one answer
1/4
5:20
This ratio 5/20. Divide both by 5. You'll get 1/4. 1/4 is 1:4
1:4
1:4 is the ratio we had before.
3:12
This ratio is 3/12. Divide both by 3. You'll get 1/4. 1/4 is 1:4
1:4
8:33
This ratio can not be reduced further.
So, the solution is 8:33 which has a different ratio from all the other ones
Answer:
The answer is D. A regular octagon has only four lines of symmetry.
Step-by-step explanation:
10x+5=8x-15
Combine like terms
10x-8x and 5-(-15)
2x=20
Divide 2 both side
Giving x=10
Answer:
659.1
Step-by-step explanation:
6.591 * 100
=> 659.1 (We can just move the decimal point 2 places to the left because this is multiplication)
This is the same pattern used in all of the questions,
Pattern - Multiplying by powers of 10, which results in shifting of decimal places
