Question 1:
(x*3)+18/8=9 is the equation
(x*3)+18=72 multiply by 8
(x*3)=54 Subtract 18
x=18 Divide by 3
The two digit number is 18
Question 2:
x*4=43 Divide by 4
x=10.75 10 3/4
10 3/4+3 3/4 Solve

Answer:
4
Step-by-step explanation:
Since the base angles are the same, the side have to be the same
ML = MN
4x = x+3
Subtract x from each side
4x-x = x+3-x
3x= 3
Divide by 3
3x/3 = 3/3
x = 1
We want the length of MN
MN = x+3 = 1+3 = 4
There are many expressions equivalent, it just needs the answer to also equal 2.
2×1
3-1
4÷2
1+1
so on
Divide the long leg by the square root of 3 to find the short leg. Double that figure to find the hypotenuse.
