Answer:
yes
Step-by-step explanation:
Answer:
Length BC = 26
Step-by-step explanation:
Perimetre = 94
; Perimetre = 2(2x + 3) + 2(3x - 1)
; 94 = 4x + 6 + 6x - 2
; 94 - 4 = 10x
; 90 = 10x
;Therefore the value of x = 9....Hence the length of BC
BC = 3(9) - 1
; BC = 26
Answer:
2/5m - 1/5
Step-by-step explanation:
distribute the 2 to every term in ()
2(1/5m-2/5) = 2/5m - 4/5
now you have 2/5m -4/5 +3/5
combine like terms variables with variables, non- variables with non-variables. -4/5 + 3/5 = 1/5
2/5m - 1/5

Here we need to set a system of two linear equations in two variables. So:
- <em>The sum of digits in a two digit number formed by two digits from 1 to 9 is 8:</em>
Let be those digits, then:
- <em>If 9 is added to a number then both the digits become equal. find the number:</em>
<em />
<em /><em />
<em />
But from eq 1:
Substituting y into the expression 1:
The x-value will be found by hit and trial, so:
We have to reject this solution because digits are different.
We have to reject this solution because digits are different.
<em>Then this is a two digit number formed by two equal digits. </em>
Finally, the number is:
44
