Answer:
x = 15
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
3+6x + 5x+12 = 180
Combine like terms
11x+15 = 180
Subtract 15 from each side
11x+15-15 =180-15
11x = 165
Divide by 11
11x/11 =165/11
x =15
Answer:
546 manogoes
Step-by-step explanation:
Sadie has mangos and watermelons in a ratio of 91:11.
We need to find the number of mangoes if she has 66 watermelons.
It means that,
11x = 66
x = 6
So,
Mangoes = 91x
= 91(6)
= 546
Hence, there are 546 mangoes.
Answer:
3,800 = 38 * 100
Step-by-step explanation:
3.8 * 100
= 380
38 * 100
= 3,800
There is no missing exponent or factor, it's just 3.8 needs to be multiplied by 10.
19.95 + 3.98x = 63.73
3.98x = 63.73 - 19.95
3.98x = 43.78
x = 43.78/3.98
x = 11
