Answer:
1.06 × 5(r-4) = 45.05
Step-by-step explanation:
Let r represents the regular price of each T-shirt,
After getting $ 4 off in regular price,
New price of each T-shirt = r - 4,
Thus, new price of 5 T-shirts = 5 × price of each T-shirt
= 5(r - 4)
Since, there is 6% sales tax,
Then, the final price after discount = 5(r - 4) + 6% of (5(r-4))
= 5(r-4) + 0.06(5(r-4))
= 1.06 × 5(r-4)
According to the question,
1.06 × 5(r-4) = 45.05
Which is the required equation.
Answer:
the answer should be 
or 11^5
Explanation:
Since there are five 11 in the equation, the answer should be or 11^5
You shouldn't write 161051 as the answer because it is NOT a exponent.
No solution of the system of equations y = -2x + 5 and -5y = 10x + 20 ⇒ 2nd answer
Step-by-step explanation:
Let us revise the types of solutions of a system of linear equations
- One solution
- No solution when the coefficients of x and y in the two equations are equal and the numerical terms are different
- Infinitely many solutions when the coefficients of x , y and the numerical terms are equal in the two equations
∵ y = -2x + 5
- Add 2x to both sides
∴ 2x + y = 5 ⇒ (1)
∵ -5y = 10x + 20
- Subtract 10x from both sides
∴ -10x - 5y = 20
- Divide both sides by -5
∴ 2x + y = -4 ⇒ (2)
∵ The coefficient of x in equation (1) is 2
∵ The coefficient of x in equation (2) is 2
∴ The coefficients of x in the two equations are equal
∵ The coefficient of y in equation (1) is 1
∵ The coefficient of y in equation (2) is 1
∴ The coefficients of y in the two equations are equal
∵ The numerical term in equation (1) is 5
∵ The numerical term in equation (2) is -4
∴ The numerical terms are different
From the 2nd rule above
∴ No solution of the system of equations
No solution of the system of equations y = -2x + 5 and -5y = 10x + 20
