Answer: -48x-16

Step-by-step explanation:

-8-8(6x+1)

So we are going to let the first -8 stand still for a moment and focus on the "-8(6x+1) part. We will solve this using distributive property.

-8 x 6x = -48x

and

-8 x 1 = -8

This is our new problem -8 -48x -8 .

Lets do like terms. Our like terms are (-8) and (-8). And we know -8 -8 = -16.

Now we'll add that to our (-48x) . I hope you can understand this!

Karin's mom runs a dairy farm. Last year Betty the cow gave 375 litres less than twice the amount the amount from Bessie the cow
Oduvanchick [21]

Answer:

The volume of milk each cow produce are:

Betty = 851 litres

Bessie = 613 litres

Step-by-step explanation:

Let the volumes of milk from each of them be:

Betty = X litres

Bessie = Y litres

We are given the following information:

X = 2Y - 375 . . . . . . (1)     <em>(Betty the cow gave 375 litres less than twice the amount the amount from Bessie the cow)</em>

X + Y = 1464 . . . . . . (2)    <em>(Together Betty and Bessie produced 1464 litres of milk)</em>

Next, we will replace the value of 'X' in equation (2) with equation (1) as follows:

X = 2Y - 375 . . . . . . (1)  ;   X + Y = 1464 . . . . . . (2)

Therefore, equation (2) becomes:

(2Y - 375) + Y = 1464

2Y + Y - 375 = 1464

3Y - 375 = 1464

3Y = 1464 + 375 = 1,839 (divide both sides by 3)

∴ Y = 1839 ÷ 3 = 613 litres

Finally, from equation 2, we have X + Y = 1464 ; since Y = 613, solving for X:

X + Y = 1464

X + 613 = 1464

X = 1464 - 613 = 851 litres

Therefore:

Betty (X) = 851 litres

Bessie (Y) = 613 litres

Consider the diagram and the derivation below. Given: In △ABC, AD ⊥ BC Derive a formula for the area of △ABC using angle C. It i
Sedbober [7]

Answer:

A=\frac{1}{2}a*b*sin(C)

Step-by-step explanation:

First consider the diagram:

Now, we know that

Sin(C)=\frac{AD}{AC} \\ Sin(C) =\frac{h}{b} \\h=bsin(C)

Now, the area of the triangle ABC is given by,

A=\frac{1}{2}*BC*AD\\\\A=\frac{1}{2}*a*h\\\\A=\frac{1}{2}*a*c*sin(C)\\\\A=\frac{1}{2}a*b*sin(C)

Solve the formula for the perimeter of a rectangle, with width w and length I,
Komok [63]

Answer:

( P -2w) /2 = l

Step-by-step explanation:

P= 2W + 2l

Subtract 2W from each side

P= 2W -2W + 2l

P -2W = 2l

Divide by 2

( P -2w) /2 = l
