solve the systems of equations for
y=x+16
y=5x-12

Answers

Answer 1

Answer:

(7, 23).

Step-by-step explanation:

y=x+16

y=5x-12

Subtract the equations

0 = x - 5x + 16 - (-12)

-4x + 28 = 0

4x = -28

x = 7

plug x = 7 in first equation:

y = 7 + 16 = 23.

The formula is:

V=Bh or V= l x w x h

I will use the l x w x h

So we know what the values are for each unit, so we would plug them in:

L x W x H = 10 x 2.3 x 4.5

Multiply the values which gets you 103.5


So the answer is 103.5 units cubed.

The answer is 103.5 cm.

To find volume: length x width x height

10 x 2.3 x 4.5 = 103.5

There are 20 students in the drama club. Next year, 5
students will leave the drama club and some students
will join. If d is the number of students who will join the
drama club, write an expression to represent the total
number of students in the drama club next year.

Answers

Answer:

27

Step-by-step explanation:

Let d = number Of drama club members

let y = number of yearbook club members

now you can write two equations, one for the total number of students, and one for the difference between them.

d + y =64

d - y = 10

 

to solve for d, add these two lines together (so as to remove the y’s)

2d + 0y = 74

d = 37

now substitute back into one of the formulas

d+y=64

37+y=64

subtract 37 from each side,

y = 27

Solve for x.
Need help, please

Answers

Given:

The figure of a triangle with mid segment.

To find:

The value of x.

Solution:

According to triangle mid-segment theorem, the mid-segment of a triangle is parallel to the base and the length of the mid-segment is half of the base.

Using the triangle mid-segment theorem, we get

[tex]AB=\dfrac{1}{2}EG[/tex]

[tex]x+14=\dfrac{1}{2}(17+x)[/tex]

[tex]2(x+14)=17+x[/tex]

[tex]2(x)+2(14)=17+x[/tex]

On further simplification, we get

[tex]2x+28=17+x[/tex]

[tex]2x-x=17-28[/tex]

[tex]x=-11[/tex]

Therefore, the value of x is -11.
