Mathematics

Answer:

Step-by-step explanation:

3(n+4)=1/2(6n+4)

We simplify the equation to the form, which is simple to understand

3(n+4)=1/2(6n+4)

Simplifying:

3*(n+4)=0.5*(6n+4)

Reorder the terms in parentheses

+(+3n+12)=0.5*(6n+4)

Remove unnecessary parentheses

+3n+12=0.5+*(+6n+4+)

Reorder the terms in parentheses

+3n+12=+(+3n+2)

Remove unnecessary parentheses

+3n+12=+3n+2

We move all terms containing n to the left and all other terms to the right.

+3n-3n=+2-12

We simplify left and right side of the equation.

n=-10

0=-10

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

PLZ HELP ME ASAP<br> algebra 2 word problem
Ostrovityanka [42]

Give each month a number:

January = 0

February = 1

March = 2

April = 3

Now set X to 3 in the equation ad solve for t.

t = -30cos(x/6) +60

t = -30cos(3/6) +60

t = 33.672 degrees. ( Round as necessary)

You would need to change the +60 to a new starting point based on what the rise in temperature is due to global warming.

Regular quadrilateral pyramid with base edge b=55 mm and lateral edge l = 7cm. Find the sum of all edges
egoroff_w [7]

Answer:

50cm or 500mm

Step-by-step explanation:

There are 4 base edges and 4 lateral edges, therefore, multiply the number for both edges by 4 and add.

Considering the fact that we were given two units of measurement, millimeters and centimeters, but we know that there are 10mm (millimeters) in a cm (centimeter) , we can just divide 55 by 10 to get 5.5.

¦

Therefore;

5.5 x 4 = 22

7 x 4 = 28

28 + 22 = 50cm

The diagram can be drawn in order to assist in answering the question.

1 - 3x = 3x + 1 solve for x
lakkis [162]

Answer: x = 0

Step-by-step explanation:

1 - 3x = 3x + 1

then add 3x on both sides

1 = 6x + 1

then subtract 1 on both sides

0 = 6x

then divide by 6 on both sides

0 = x

so x = 0
