Answer:
25% discount
Step-by-step explanation:
48*2=96
However, instead one pair is 50% off. So, one pair will be $48 and another will be $24. So, if you purchase two pairs, you only have to pay$72. 72/96=.75. This means you are paying for 75% of the original price, meaning you got 25% off discount.
Answer:
x = 36 and y = 28
Step-by-step explanation:
Let she sells x shakes and y doublescoop cones
One day they sold 8 more shakes than scoops, and made $156.
ATQ,
2x+3y = 156 ..(1)
Also,
x = y+8 ..(2)
Put the value of x from (1) to equation (2)
2(y+8)+3y = 156
2y+16+3y = 156
5y = 156 - 16
5y = 140
y = 28
Put the value of y in equation (2)
x = 28+8
x = 36
<em>Hence, they will sell 36 shakes and 28 doublescoop cones.</em>
Answer: I think it's because you can't have two of the same numbers in the domain. For example the (5, -3) and the (5,2)
Step-by-step explanation:
The value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2
<h3>System of equation</h3>
For a system of equation to have no solution, the expression on both sides must be different.
Given the system of equation
6x-5y=3 and
3x+ay=1
For the equations to have no solution, the a1/a2= b1/b2
Substitute
6/3 = -5/a
Cross multiply
2 = -5/a
a= -5/2
Hence the value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2
