Answer:
6x^2-23x+20
Step-by-step explanation:
i think the expanded form of that equation is equal to it.
(3x-4)(2x-5)
3x(2x-5)-4(2x-5)
6x^2-15x-8x+20
6x^2-23x+20
I hope this helps and sorry if it's wrong
Answer:
220
Step-by-step explanation:
40 x 8 = 320, and 10 squared is 100. 320 - 100 = 220.
Let's make variables for two angles first. One angle will be x, and the other will be y.
Since they're supplementary, we know x + y = 180
We also know x = y - 32, since it's 32 degrees less than it's supplement.
Input the value of x into the first equation and...
y - 32 + y = 180
2y - 32 = 180
Add 32 to both sides:
2y = 212
Divide both sides by 2:
y = 106
We can solve for x in two ways.
One, we can subtract 32 from 106 since x is 32 degrees less.
Or, we could also just subtract 106 from 180 since we know the angles are supplementary.
x = 74
74 degrees and 106 degrees. The equation is y - 32 + y = 180, or x + y = 180
Answer:
$62.10
Step-by-step explanation:
To calculate how much the employee's discount actually was, we just multiply the original price by the discount
Plug the prices in --> 138 x 45/100
Simplify 45/100 --> 9/20
138/1 x 9/20 = 1242/20
1242/20 = 62.1
62.1 = $62.10
and thus, the discount is $62.10
Answer:
(32.50 x 2) - 49.13 - (74.25 x 2)
Step-by-step explanation:
49.13 (32.50 + 32.50) - 49.13
$67.00 - $49.13
-17.87
$74.25 x 2 = $148.5
148.5 - 17.87 = 130.63
