I would guess 61 in my school we only do things like this x4 - 5 x times four minus five so I don’t know if that’s right but that would be my guess if that isn’t right it would be 62 times 2
Y = 3x + 3
y = x - 1
As you can see, both equations are set to equal y. This means the right sides of each equation are equal, since y is isolated in both equations. So to solve this particular system of equations for x, set the right sides of both equations equal to each other. After you've done that, you can proceed to solve the equation algebraically for the variable, x.
3x + 3 = x - 1
2x + 3 = -1
2x = -4
x = -2
Negative two is the x-value. To find the y-value, substitute -2 for x into either equation and solve algebraically for y.
y = x - 1
y = -2 - 1
y = -3
The final step is to check all work by plugging both x- and y-values back into both equations.
y = 3x + 3
-3 = 3(-2) + 3
-3 = -6 + 3
-3 = -3 -- This is true
y = x - 1
-3 = -2 - 1
-3 = -3 -- This is true.
Answer:
(-2, -3)
10% of $560 is $56
So 5% is $28
1% of $560 is $5.60
So now half $5.60 is $2.80
$2.80 is 0.05%
Now add
$28 + $2.80 = $30.80
Total is $30.80
Answer:
The employee discount is 30% off. Here's the process to find this answer:
Calculate the difference between the original price and the discounted price. We're trying to find the percentage of the discount, not the percentage 38.50 is of 55.
55 - 38.5 = 16.5
Multiply the difference by 100 as part of the percentage formula. (is over of is equal to the percentage over one hundred)
16.5 * 100 = 1,650
Divide your result by 55 as the final part of the percentage formula.
1,650 / 55 = 30
