First, move all terms containing a to the left, all other terms to the right.
Add '2b' to each side of the equation.4a + -2b + 2b = 16 + 2b
Combine like terms: -2b + 2b = 04a + 0 = 16 + 2b4a = 16 + 2b
Divide each side by '4'.a = 4 + 0.5b
Answer
= 4 + 0.5b

Answer:
5 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (6, 4)
d = 
= 
= 
= 
= 5
Answer:
5
Step-by-step explanation:
You can express this as a system of equations:
x in this instance will be her present age.
x + 8 = 2x + 3
simply solve for x after this by subtracting three and x from both sides, and you’ll find that x is 5.
Answer: 120
Step-by-step explanation:
3 x 108 = 324
3 x 102 = 204
so 324 - 204 = 120
3 are expected to have the condition.
The expected value is the found by multiplying the probability by the number in the sample:
(1/200)×600
= (1/200)×(600/1)
= (1×600)/(200×1)
= 600/200 = 3
