How to solve X - 1v+ 4 + 7y - 3

1 answer:

3 0

The first step to solving this is to remember our mathematical rules. They state that when the term has a coefficient of -1,, the number doesn't have to be written but the sign needs to remain. This will change the expression to the following:
x - v + 4 + 7y - 3
Now subtract the numbers 4 and 3 from each other.
x - v + 1 + 7y
Since this expression cannot be simplified any further,, the correct answer to your question would be x - v + 1 + 7y.
Let me know if you have any further questions.

A triangle has two angles with measures of 90 and 20 degrees joined by a side with a length of 12 centimeters.

vichka [17]

Answer: C

Step-by-step explanation:

We know that A and D will not be the correct answers. For A, it's only one 90 angles, but the questions said that has two angles. For D, it's two angles : 90 and 12, but in the question, 12 is the length, not the angle.

The correct answer is C.

If you are looking for the height of a pyramid and the volume is 18,069,333.33333 and the length and width are both 440 what is

makkiz [27]

Answer:

h=123,200

Step-by-step explanation:

First you must in the formula for the pyramid, which is

$v=\frac{wlh}{3}$

and as far as the question has gave us

V=18069333.33333

LW=440

1.) Plug those numbers into the the equation, which should be:

$(18,069,333.33333)= \frac{(440)h}{3}$

2.) Then isolate the "h" by dividing both sides by $\frac{440}{3}$ , or multiplying its reciprocal, which is $\frac{3}{440}$

$(\frac{3}{440}) 18,069,333.33333=\frac{440h}{3} (\frac{3}{440} )$

3.) Simplify or round the numbers if you need to.

$h= 123,200$
