Answer:
X = 2
Step-by-step explanation:
First we'll need to simplify this equation:
Add 9x on both sides:
13x - 21 = 5
Add 21 on both sides:
13x = 26
Divide 26/13
26/13 = 2
X=2
(You can check this yourself by plugging x into the equation)
Answer:
The admission cost of each adult is $11.5 and that of each children is $6.5.
Step-by-step explanation:
Let the admission cost for children to the museum is $x.
So, the admission cost for adults to the museum is $(x + 5) {As per given condition}
Now, given that admission to the museum for Barbara and Jeff Johnson and their five children cost fifty-five dollars and fifty cents.
Hence, 2(x + 5) + 5x = 55.5
⇒ 7x = 45.5
⇒ x = $6.5
So, $(x + 5) = $11.5
Therefore, the admission cost of each adult is $11.5 and that of each children is $6.5. (Answer)
Width is 3 cm and length is 12 cm
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x. Then the length = 4x. Find the dimensions if perimeter = 30 cm
Perimeter of the rectangle = 2 (length + breadth)
30 = 2(x + 4x)
30 = 10x
⇒ x = 30/10 = 3
⇒ 4x = 12
