Answer: Larry thought of the number 14
Step-by-step explanation:
Let the number be represented by x
Such that when added with 1 becomes x+1
Multiplied by 2 becomes 2(x+1)
divided by 3 gives 2(x+1)/3
Upon subtraction with 4, we have
2(x+1)/3 -4=6 as the equation
Solving
2(x+1)/3 -4=6
2(x+1)/3=6+4
2(x+1)/3=10
2(x+1)=3x10
2(x+1)=30
2x+2=30
2x=30-2
2x=28
x=28/2
x=14

Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55
Answer:
9
Step-by-step explanation:
Since drainage is to be included in the possible combinations, we can therefore determined the number from the remaining 6 options which can be in combination with drainage
(6 2) = 15 pairs.
Now there are restrictions placed, where we have no pairing of damp roofing with bricklaying or plastering. This removes two pairs, so we are left with 13pairs.
Another restrictions is that students choosing Joinery must also choose Flooring. This gives the three options: joinery, flooring and drained with no pairing with the remaining four pairs this removing another four pair.
So we are left with 9 pairs in total.
