Answer:
lol you've asked like 10 probability questions in 20 minutes i wonder what chapter you're studying
Step-by-step explanation:
Answer:
(5, 4 )
Step-by-step explanation:
Given the 2 equations
3x - y = 11 → (1)
- 2x - 4y = - 26 → (2)
Multiplying (1) by - 4 and adding to (2) will eliminate the y- term
- 12x + 4y = - 44 → (3)
Add (2) and (3) term by term to eliminate y
- 14x + 0 = - 70
- 14x = - 70 ( divide both sides by - 14 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
3(5) - y = 11
15 - y = 11 ( subtract 15 from both sides )
- y = - 4 ( multiply both sides by - 1 )
y = 4
solution is (5, 4 )
Volume of large prism: 8 x 4 x 2 1/4 = 72 cubic inches
volume of small prism: 1/4 ^3 = 0.15625 cubic inches
72 / 0.15625 = 4,608 cubes
seven ones and 6 hundredths
I hope this helps you
