Answer:Price of laptop A = $1220
Step-by-step explanation:
Sum of the price: A + B = 2185
Sum of the price: A + C = 2571
B : C = 5 : 7
B = 5/7 × C
So, replace the B:
A + 5/7 C = 2185
A + C = 2571
Eliminate by subtracting the first from the second: 2/7 C = 386
C = 1351
So, A = 2571 - 1351 = 1220
The answer is -43, you have to substitute in this question, the question would look like 4(-4)-3^3. Hopes this helps
The price before discount is: 40.11 : 80%= 50.1375
The tax before sales is 1.91 : 80%= 2.3875
And the original price of the sweater is 50.1375+ 2.3875= 52.525
The original price is $52.525
Answer:
x = -3
Step-by-step explanation:
5(x-2)+3x-4 = -38
=> 5x-10+3x-4 = -38
=> 5x+3x-10-4 = -38
=> 8x-14 = -38
=> 8x = -38+14
=> 8x = -24
=> x = -24/8
=> x = -3
