Answer:
Step-by-step explanation:
We have three people
jamal = x (since im guessing hes the youngest)
wesley= x+1
John= x+2
the formula you would use is x+x+1+x+2=108
when you simplify that you get 3X+3=108
you subtract the 3 from 108 which leaves you with 3X=105
divide that by 3 which makes x=35
so
jamal is 35
wesley is 36
john is 37
Answer:
B) Associative Property of Multiplication
Step-by-step explanation:
The associative property states you can change where the parentheses (grouping terms) are in a multiplication statement, and you'll get the same product.
More generally:
(a * b) * c = a * (b * c)
Answer:
Step-by-step explanation:
y ∝ x^2
Introducing the proportionality constant, we have
y = kx^2
Given : y= 18 when x = 3
substitute the given values in order to get the constant
i.e 18 = k x 3^2
18 = 9k
k = 2
therefore the formula connecting x and y
⇒ y = 2x^2
To find y if x is 4, just substitute x = 4 into the formula connecting x and y
i.e y = 2 x 4^2
= 2 x 16
= 32
Answer:
12.50
Step-by-step explanation:
Each yogurt is $1.25. 1.25 x 4 = 5. so 1.25 x 10 = 12.50.
