Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.
Answer:
j = 2z + 1

twice zacks age or two times zacks age.
jennifer's age is two times zacks age plus one or
j = 2z + 1
You would set it up as .2 x 26, which would be 5.2

Answer:
Barett Sold 88 Tickets
Step-by-step explanation:
To Start off we are told that the Total of tickets sold between Amelia (A) and Barrett (B) was 137.
Total = 137
Since Barett Sold 10 less than twice as many tickets as Amelia, we can make the following equation, where Barett is B and Amelia is A.
A + B = 137
A + (2A-10) =137 (Barett equalls 10 less than twice Amelia)
Now we can solve the equation for A
A + (2A-10) =137
3A - 10 = 137 (Combine Like Terms)
3A = 147 (add 10 on both sides)
A = 49 (divide by 3 on both sides)
Now that we have the amount of tickets that Amelia sold we can plug it in for B to find out how many tickets Barett Sold
(2A-10) = B
(2*49) - 10 = B
(2A-10) = B
98 - 10 = B
88 = B
