You want to do l*w*h=v then if you have two answers add them together and you should get the answer.

By the way I'm 11 and in sixth grade going on to 12 and going to be in seventh grade next year

What is the answer for -5(3x-9)=2(x-63)-33?

Sladkaya [172]

It would be: -5(3x-9) = 2(x-63)-33
-15x + 45 = 2x - 126 - 33
-15x - 2x = -204
17x = 204
x = 204/17
x = 12

In short, Your Answer would be 12

Hope this helps!

A line passes through (0, –7) and has a slope of -2/3. What is the equation of the line in slope-intercept form

babunello [35]

Answer:

the required equation is y = ( -2/3 )x -7

Step-by-step explanation:

Given :- 

the line passes through the point ( 0 , -7 )

)and slope of the line is ( -2/3 )

• To form an equation when one point and it's slope is given ,

• To form an equation when one point and it's slope is given , we use ;

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variables

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet !

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet ! and m is slope of the tangent !!

y1 = -7

x1 = 0

So, putting all the values in the equation we get ,

$(y - ( - 7)) = \frac{( -2 )}{3} (x - 0) \\ \\ y + 7 = \frac{ - 2}{3} x \\ \\ 3y + 21 = - 2x \\ \\ 3y = - 2x - 21$

$3y = - 21 - 2x \\ \\ y = \frac{ - 2}{3} x - \frac{21}{3 } \\ \\ y = \frac{ - 2}{3} x - 7$

• Slope intercept form of the equation

• Slope intercept form of the equation y = mx + c

• Slope intercept form of the equation y = mx + c Where , m is slope of the line

• Slope intercept form of the equation y = mx + c Where , m is slope of the line and c is y intercept !!

[ also , we can directly put the value of c = -7 and m = ( -2/3 ) from given ]

Hence , here m = (-2/3 ) and c = -7

So, the required equation is y = ( -2/3 )x -7

Write the sentence as an equation. 373 plus the product of 169 and u is t Type a slash ( / ) if you want to use a division sign.

Masja [62]

373 + (169 * u ) = t

The equation above is your answer.

Just remember "product" means the answer to a division problem and "is" usually means that you should insert an equals sign.
