Answer:
36cm
Step-by-step explanation:
The scale is 3 to 1, so the poster size is 3 times larger than the actual thing.
adult ticket = 10
child ticket = 4
Step-by-step explanation:
for example…
- adult ticket = x
- child ticket = y
so that we get a system of equations
9x + 5y = 110…Equation 1
x + y = 14…Equation 2
solve the system of equations, this time I will use the Elimination and Substitution method
9x + 5y = 110
x + y = 14 (multiplied by 5)
↓↓↓↓↓↓↓
9x + 5y = 110
5x + 5y = 70
___________ _
4x = 40
<u>x = 10</u>
to find value of y subtitute x to one of Equation. for example from second Equation…
x + y = 14
10 + y = 14
y = 14 - 10
<u>y = 4</u>
∴ So, the number of each ticket was she bought is <u>10 adult ticket</u> and <u>4 child </u><u>ticket.</u>
Answer:
Y = (x + 3)(x - 4)(x + 1)^2
Y = (x^2 - x - 12)(x^2 + 2x + 1)
Y = x^4 + 2x^3 + x^2 - x^3 - 2x^2 - x - 12x^2 - 24x - 12
Y = x^4 + x^3 - 13x^2 - 25x - 12
Answer:
2(5)+5=15
Step-by-step explanation:
1. you have the equation 2b+c
2. then you add the numbers for c and b
3. so b=5 and c=5
4. once you add it into the problem then you get 2(5)+5 make sure you remember to times 2 x 5
5. then you do PEMDAS
6. you do multiply so 2x5 is 10
7. then do 10+5 and you get 15 as your answer.
