-9-x/6=2=-1/6*x=11:-1/6. X=11÷(-1/6). Therefore, x=-66
Answer:
number of youth admissions sold (x) = 74
number of adult admissions sold (y) = 32
Step-by-step explanation:
Let x = number of youth admissions
Let y = number of adult admissions
Given:
- total number of admissions sold = 106
⇒ x + y = 106
Given:
- cost of youth admission = $12.50
- cost of adult admission = $17.50
- total amount collected = $1485
⇒ 12.5x + 17.5y = 1485
Rewrite x + y = 106 to make y the subject:
⇒ y = 106 - x
Substitute y = 106 - x into 12.5x + 17.5y = 1485 and solve for x:
⇒ 12.5x + 17.5(106 - x) = 1485
⇒ 12.5x + 1855 - 17.5x = 1485
⇒ 5x = 370
⇒ x = 74
Substitute found value of x into y = 106 - x to find y:
⇒ y = 106 - 74
⇒ y = 32
Answer:
$317
Step-by-step explanation:
Formula for compound interest is;
A = P(1 + (r/n))^(nt)
For melanie;
P = $3800
r = 2⅜% = 0.02375
n = 12/4 = 3
t = 16 years
Thus;
A = 3800(1 + (0.02375/3))^(3 × 16))
A ≈ $5548
For Sébastien;
P = $3800
r = 2¾% = 0.0275
n = 12
t = 16
Thus;
A = 3800(1 + (0.0275/12))^(12 × 16))
A ≈ 5865
Difference between Sébastien and Melanie's final amount = $5865 - $5548 = $317

You are given an angle of 38 degrees, which is a supplementary angle to angle 7.
Angle 7 = 180 - 38 = 142 degrees.
Angle 7 and angle 5 are Corresponding angles, which means they are equal.
Angle 5 = angle 7 = 142 degrees.
