Answer:
A's age = 6x = 6 × 5 = 30 years.
B's age = 5x = 5 × 5 = 25 years
Step-by-step explanation:
here's the solution : -
let their ages be 6x and 5x
and we know sum of their ages = 55
So, 6x + 5x = 55
=》11x = 55
=》x = 55 ÷ 11
=》x = 5
A's age = 6x = 6 × 5 = 30 years.
B's age = 5x = 5 × 5 = 25 years
Answer:
Step-by-step explanation:
we need the equation to be like y=mx+b so we have to simplify our equation
2y=2x+6
divide everything by 2
so it’s y=x+3 and that’s ur answer
Answer:D.51

Answer:
y = (1/4)x + 0
or
y = (1/4)x
the (1/4) is supposed to be a fraction of 1 in the numerator and 4 in the denominator
Step-by-step explanation:
The given operation involves just swapping the two rows, so carrying out
on the matrix gives
![\left[\begin{array}{cc|c}5&5&5\\1&-\dfrac23&5\end{array}\right]\to\left[\begin{array}{cc|c}1&-\dfrac23&5\\5&5&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D5%265%265%5C%5C1%26-%5Cdfrac23%265%5Cend%7Barray%7D%5Cright%5D%5Cto%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%26-%5Cdfrac23%265%5C%5C5%265%265%5Cend%7Barray%7D%5Cright%5D)
