Let's use the variable "r" to represent the investment rate of the stocks:
2r(500) + r(800) = 45
1000r + 800r = 45
1800r = 45
r = 0.025
2r = 0.05
The $500 is invested at 5%
Answer:
Step-by-step explanation:
Slope of line through (-9,6) and (-6,-9) = (-9 - 6)/(-6 - (-9)) = (-15)/(3) = -5
point-slope equation for line of slope -5 that passes through (-9,6):
y-6 = -5(x+9)
Answer:
1 1/8 or 9/8
Step-by-step explanation:
Set up a proportion. The proportion will be teaspoons of chili powder over pound of vegetables.
The first proportion will be..
x is 3/4 and y is 1/2. Across from that proportion make another one
x is "n" because you're trying to figure out how much chili powder you need. y is 1 3/4.
Multiply 3/4 and 1 3/4, which is 9/16. Then, divide 9/16 and 1/2, which is 9/8. Simplify it to 1 1/8, and Maxwell will need 1 1/8 teaspoons of chili powder.
Hope this wasn't too confusing :)
Multiplication, hope I could help!
