If she would have waited a day she would have saved D) $64.43 more. This is because the original sale price comes to $322.15 and then we find the answer by taking this number and multiplying it by the additional sale and get $64.43.
Answer:
x=5
y=7
Step-by-step explanation:
y = x+2 so plug that in the next equation as y
so it be --> 5x+(-4)(x+2)= -3 now use distributive property
(-4 times x)+(-4 times 2)= -4x+-8 replug that back in
5x-4x+-8 = -3 subtract your x
1x = x so ---> x+-8 = -3 now to get rid of -8 we have to add 8 to it
x= -3 but whatever you do to one side u do to the other so u have to add 8 to -3---> so it be x=5
now take that x=5 and plug it in to your first eqaiuton to get y
y=5+2 ---> y =7
Answer:
D.) x = 7
Step-by-step explanation:
4x - 9x + 3 = -32
The first thing we do is combine like terms which means to add or subtract or multiply or divide any numbers that are known. Here in this equation we have 4x and - 9x
4x - 9x + 3 = -32
- 5x + 3 = - 32
Now what we do is subtract the common numeral from the side where the x value is.
- 5x + 3 = - 32
- 3. - 3
- 5x = - 35
Lastly, we divide here we take the value next to x and divide both numbers, here we will divide by - 5.
- 5x = - 35
- 5x / - 5 = x
- 35 / - 5 = 7
Now we take are two solutions and create are final solution.
x = 7
