When You Evaluate the expression you the Answer D) 54
Answer:
$1000
Step-by-step explanation:
We can form an equation for Clayton's account: C = 500 + 10x
We can form an equation for Clayton's account: J = 400 +12x
(where x is the number of days)
When the two accounts will contain the same amount, it means: C = J
<=> 500 + 10x = 400 +12x
<=> x =50
After 50 days, there accounts will be balance. Then, we substitue x into any of the 2 equation to find out the amount: 500 + 10(50) = $1000
Answer:
4
Step-by-step explanation:
Answer:
r≈12.89
Step-by-step explanation:
Using the formula
C=2πr
Solving for r
r=C
2π=81
2·π≈12.89155
Answer:
no
Step-by-step explanation:
first simplify or solve the original expression ( 3(x + 11/2)-3 )
1. Parenthesis go first so do the 11/2 = 5.5 (x+5.5)
2. Distribute the 3 to the parenthesis (3x + 16.5)
3. subtract 3 from the expression (3x + 13.5)
Compare new equation with 3x + 11/2. Are they the same? (3x+13.5 vs. 3x + 11/2)
They are not the same thing.
