vredina [299]

Answer:

$11500

Step-by-step explanation:

Given

Tax amount=$1437.50

Tax percentaege=12.5%

So, we have to find the price of motorcycle whose 12.5% is 1437.50

Mathematically writing,

Let

x be the price of motorcycle without tax

then, the equation will be written as:

x*0.125=1437.50

x= 1437.50/0.125

x=11500

So the price of motorcycle without tax was $11500..

2x+6 - х -4

2x - x = - 4 - 6

x=-10

20x - 8 = 18x +6

20x - 18x = 6 +8

2x = 14

How do you simplify this and write as a polynomial in standar form? (x-9)3x-7)+(3x^2-5x+2)

nasty-shy [4]

Answer:

Standard form of $(x-9)(3x-7) + (3x^{2} - 5x+2)$ $=6x^{2} - 39x + 65$

Step-by-step explanation:

Here, the given expression is $(x-9)(3x-7) + (3x^{2} - 5x+2)$

Now, simplifying the above expression in parts, we get

$(x-9)(3x-7) = 3x^{2} - 7x -27x + 63 = 3x^{2} - 34x + 63$

hence, combining both parts:

$(x-9)(3x-7) + (3x^{2} - 5x+2)$ $=(3x^{2} -34x +63) + (3x^{2} - 5x+2)$

= $6x^{2} - 39x + 65$

The above expression is of the STANDARD FORM: $ax^{2} +bx + c$

Hence, the standard form of $(x-9)(3x-7) + (3x^{2} - 5x+2)$ $=6x^{2} - 39x + 65$

What is the value of y

Reil [10]

All angles in a triangle add up to 180
So 79+37=116
180-116=64
Y=64
