Answer:
45.75
Step-by-step explanation:
183/4=45.75.
Answer:
Step-by-step explanation:
m = 4 ; (1,-2)
y - y₁ = m (x - x₁)
y - [-2] = 4 (x - 1)
y + 2 = 4x - 4
y = 4x - 4 - 2
y = 4x - 6
2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.
Answer: If you take 4 times 6 you get 24, so take 3*6 to get an 18-foot shadow. 4:3=24:18. I hope this helps. I'm not sure what your choices are, though.
