Since the dimension of the scale model is fourth of dimensions of the room, divide by 4 the given dimensions.
new dimensions:
= 18 ft / 4 = 9/2 ft
= 16 ft / 4 = 4 ft
The area is calculated by multiplying the dimensions,
Area = (9/2 ft)(4 ft) = 18 ft²
Therefore, the area of the scale model is equal to 18 ft².
Answer: Jiří is 5 years old.
Step by step:
Let x denote Jiří's age in years. Then Pamela's age is 3x. Their sum is x + 3x = 20. So we solve for x:
x + 3x = 20
4x = 20
x = 5
Jiří's age is 5 years
Answer:
-43
Step-by-step explanation:
first we need to do 9x witch would be 9x3 so 9x3 is 27 now its down to -16 - 27 and that is -43
To isolate the variable multiply both sides by 5.
-3 = x/5
-3*5 = x/5 * 5
-15 = x
