Answer:
Option 2:
The variable a should be multiplied by Two-thirds only and then added to 10.
Step-by-step explanation:
Let the age be a
The sum of 10 and two-thirds of that tree’s age:
10 + ⅔a
is equal to 50:
10 + ⅔a = 50
⅔a = 40
a = 60
Answer:
41 purple marbles
Step-by-step explanation:
x= amount of purple marbles
3x+x=164
4x=164
x=164/4=41
Causation conclusion can only be made when the experiement is preformed. Due to the potential confounding variables in observational studies which include random samples.
2/8000 = 16/x....2 oz to 8000 flowers = 16 oz to x flowers
cross multiply
(2)(x) = (8000)(16)
2x = 128,000
x = 128,000/2
x = 64,000 flowers are needed
Answer: The perimeter is doubled
Step-by-step explanation:
When you double the length and width you have 2l as length and 2w as width. The new perimeter is 2(2l)+2(2w)=2(2l+2w). This means that when you double both sides, the perimeter is doubled.
