Answer:
10x +6y - 14
Step-by-step explanation:
3x - 2y = 13x + 4y = 14
3x = 13x + 6y = 14
-10x = 6y = 14
10x + 6y - 14
Answer:
18 Non Foreign Stamps
Step-by-step explanation:
Given data
Total stamps= 150
Foreign Stamps= 88% of the total stamps
Hence the number of foreign stamps is
=88/100*150
=0.88*150
=132 Foreign Stamps
The number of stamps that is Non Foreign Stamps is
=150-132
=18 Non Foreign Stamps
The equation that can be used to represent the number of albums at which the profit would be equal for the two methods of selling her album is -0.03x² + 4x + 6000 = 0
<h3>How to solve equations in the form of no quadratic</h3><h3 />
- x = the number of albums sold
- y = the profit in dollars,
Method 1, y = -0.05x² + 12x - 8000
Method 2, y = -0.02x² + 8x - 2000
-0.05x²2 + 12x - 8000 = -0.02x²2 + 8x - 2000
- 0.05x² + 0.02x² + 12x - 8x - 8000 + 2000 = 0
-0.03x² + 4x - 6000 = 0
where,
a = -0.03
b = 4
c = -600

Total no. of sandwiches = 480
No. of tuna sandwiches = 3/8*480 = 180 sandwiches
No. of beef sandwiches= 35% of 480
= 35/100*480 = 168 sandwiches
Remaining no. of sandwiches = 480-(168+180) = 132 sandwiches
Let no. of ham sandwiches be 5x
Let no. of cheese sandwiches be 6x
5x + 6x = 132
11x = 132
x = 132/11 = 12
No. of cheese sandwiches = 6x = 12*6 = 72 sandwiches
No. of ham sandwiches = 5x = 5*12 = 60 sandwiches
Answer:
115,200 feet³
Step-by-step explanation:
