Set both angles equal to each other because they are vertical angles.
3x-3 = 2x + 13
3x-2x=13+3
1x =16
x=16
Answer:
$283
Step-by-step explanation:
Let,
x - for $2 notes
x + 16 - for $5 notes
EQUATION:
(x) + (x + 16) = 74
2x = 74 - 16
2x = 58
x = 29
SUBSTITUTE
x = 29 pieces of $2 notes
x + 16 = 29 + 16 = 45 pieces of $5 notes
TOTAL VALUE IS:
(29 x $2) + (45 x $5) = $283
The answer of this expression is - 4 1/6
Answer:
10 hamburgers
Step-by-step explanation:
$2.00 x 10 = $20.00
$20.00 + $5.00 = $25.00
Because Z is directly proportional to X and inversely proportional to Y, therefore

where k = constant.
When X = 15 and Y = 9, Z = 5. Therefore
k(15/9) = 5
k = 5*(9/15) = 3
That is,

When X = 23, and Y = 14, obtain
Z = (3*23)/14 = 4.9286
Answer: Z = 4.929 (nearest thousandth)
