Ok for this problem, there are 2 equations representing hall A and hall B
hall A: y=76x+862 where x=number of dinners and y=total cost
hall B: y=75x+894 for the same variables
To find where the 2 meet, simply substitute one equation into the other, creating: 76x+862=75x+894
Solving this, we find that x=32, so at 32 guests, the cost would be the same
For part 2, put the answer for part 1 into either equation from the start, so y=76(32)+862, or y=3294
And we already found that x=32, which represents the # of guests
The answer is
3x-4y=-24
y=mx+b
-4y=-3x-24
y=(3/4)x+(-24/-4)
y=(3/4)x+6
slope m=3/4
y =6
Answer:
x=70 angle b = 70 and angle c=72
Step-by-step explanation:
all triangles add up to 180 so the equation is 2x+40=180
3/5 as a decimal would be .6, so .7 would be the bigger portion.
Answer:
9/14
Step-by-step explanation:
81/126=9x9/9x14=9/14
