Answer:
-5/3
Step-by-step explanation:
5x+3y=6
3y=6-5x
3y=-5x+6
y=-5/3x+6/3
y=-5/3x+2
parallel means same slope,
so the slope must be -5/3

Answer:
10 and 12
Step-by-step explanation:
let the consecutive even integers be n and n + 2 , then
n² - 64 = 3(n + 2) ← distribute parenthesis
n² - 64 = 3n + 6 ( subtract 3n + 6 from both sides )
n² - 3n - 70 = 0 ← in standard form
(n - 10)(n + 7) = 0 ← in factored form
Equate each factor to zero and solve for n
n - 10 = 0 ⇒ n = 10
n + 7 = 0 ⇒ n = - 7
Since n must be a positive even integer then n = 10 and n + 2 = 10 + 2 = 12
The 2 numbers are 10 and 12
Answer:
14 dimes = $$4.50
18 quarters = $1.40
Step-by-step explanation:
Answer:
1. $6000
2. 40.9%
3. 51.6%
4. Misc
Explained :
1. 1800 + 150 + 2450 + 1300 + 300 = 6000
2. 2450/6000 = 0.409 = 40.9%
3. 1800 + 1300 = 3100 ; 3100/6000 = 0.516 = 51.6%
4. 300/6000 = 0.005 = 5%
