Answer:

Step-by-step explanation:

- Since y = -1, we will substitute the y variable in the equation for -1.

-1 = -5/2x + 4

- Take away 4 from both sides in order to find out what x equals so we can substitute it.

5 = -5/2x

- turn it into a positive by multiplying each side by -1.

-1(-5 = -5/2x) =

5 = 5/2x

- Divide each side by 5.

1 = 1/2x

- Multiple both sides by 2.

2 = x

- Substitute the variables.

x = 2

y = -1

-1 = -5/2(2) + 4

What is the solution of the system? Use elimination.

denis-greek [22]

Eliminate y's
multiply second equaiton by 4
4x+4y=-4

add to first equation

3x-4y=-24
4x+4y=-4 +
7x+0y=-28

7x=-28
divide both sides by 7
x=-4
sub back

x+y=-1
-4+y=-1
add 4 to both sides
y=3

(x,y)
(-4,3)
D is answer

If measure of angle T= (2x + 85), measure of angle V= (5x + 29), and

netineya [11]

Answers:

Angle T = 79 degrees

Angle V = 14 degrees

=========================================================

Work Shown:

T + V = 93

(2x+85) + (5x+29) = 93

7x+114 = 93

7x = 93-114

7x = -21

x = -21/7

x = -3

This x value is used to find each angle mentioned.

Angle T = 2x+85 = 2(-3)+85 = -6+85 = 79 degrees
Angle V = 5x+29 = 5(-3)+29 = -15+29 = 14 degrees

As a check, T+V = 79+14 = 93 which confirms our answers.

Answer:

<h2>Option B:</h2><h2> $\frac{1}{5}$ </h2>

Step-by-step explanation:

Given,

Number of numbers of each side of the cube

= 4, 5, 6, 7, 8 and 9

= 6 numbers

Number of sides of cube having the number 5

= 1

Therefore, 

Probability of getting a side of the cube of no. 5 is

$= \frac{no. \: of \: favourable \: outcomes}{total \: no. \: of \: possible \: outcomes}$

$= \frac{1}{6} (ans) \: (option \: B)$
