Basically, the equation would look like this:
.50 + 200% = x
What I did was find the percent number, so after figuring out what it was it looked more like this:
.50 + 1.00 = 1.50
The answer is, the customer pays $1.50

The 7 is not a variable because variables are letters. The number seven is a coefficient because they are numbers used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients

Answer:
Tables 3 and 5
Step-by-step explanation:
The unit rate in each case can be found by dividing the first y-value by the first x-value.
Table 1: 4/3 ≈ 1.333
Table 2: 4/5 = 0.800
Table 3: 18/31 ≈ 0.581
Table 4: 11/18 ≈ 0.611
Table 5: 7/12 ≈ 0.583
The equation has a "unit rate" of 3/5 = 0.600. The tables with lower rates are ...
Table 3 and Table 5
Find the value of x and y
Answer:
Answer: x = 33, y = 81..........
You can see that the two lateral and vertical sides of the quadrilateral are congruent respectively, meaning that ∠3x = ∠(2x+33).
You also know that 3x + y = 180° since they're supplementary.
To solve for x, just solve the equation I wrote above:
3x = (2x+33) (subtract 2x from both sides, and that automatically gives you
x = 33 the value)
To solve for y, plug it into the second equation I provided:
3(33) + y = 180
99 + y = 180
y = 81
∴ x = 33, y = 81
Vanessa bought a laptop at a 20% discount. The original price of the laptop was $275.00. How much money did Vanessa save?
Answer:
$55.00
Step-by-step explanation:
20% of 275 is 55. Meaning she saved 55 dollars.
Answer:
Vanessa saved $55, and she only had to pay $220.
Step-by-step explanation:
First we need to convert 20% into a decimal, 0.20.
Now we need to multiply 275 and 0.20.
275 × 0.20 = 55
275 - 55 = 220
