Answer: the 4th boy is 11
Step-by-step explanation:
Let's denote the age of the boys as: x₁, x₂, x₃, x₄.
Then,
Multiply both parts of the equation by denoting by 3:
x₁+x₂+x₃=15(3)
x₁+x₂+x₃=45
Hence,
Multiply both parts of the equation by denoting by 4:
45+x₄=14(4)
45+x₄=56
45+x₄-45=56-45
x₄=11
6 3/8
Multiply the whole number with the denominator
6*8= 48. Add 3 ( numerator) with 48.
48+3= 51
51/8
Answer: 51/8
Answer:
54
Step-by-step explanation:
12+(8)4-6
12+48-6
60-6

So find factors of 5
1 and 5
both factors must be both negative or both positive to be positive 5
adds to negative 4
to do that, they both must be negative
-5 times -1=5
-5+-1=-6
doesn't work
the only way it would work is if it is what multipies to -5 and adds to -4 which then the numbers would be -5 and 1
