Justify each step x/3-7=11 x/3=18 x=6

Schach [20]

This is the steps for equation solving for the value of x,

x/3-7 = 11

now 7 goes to the other side of equation by changing the sign from - to +,

x/3 = 11 + 7

x/3 = 18

now when we multiply both sides of equation with 3 or 3 goes to the other side of equation and multiply with 18 leaving x alone here for finding the value of x,

and we get, x = 54

at the end of equation we get x = 54, if the equation was in the form 3x - 7 = 11, then we will get x = 6

Homework I have to turn in on Monday please help

nasty-shy [4]

Answer:

If you're trynna simplify these are the answers:

4.) -116

5.) -13

Step-by-step explanation:

4.) −4((5)(4)+9)

=(−4)((5)(4)+9)

=(−4)((5)(4))+(−4)(9)

=−80−36

=−116

5.) 9+84−(6)(4)

=9+2−(6)(4)

=11−(6)(4)

=11-24

= -13

Solve ABC <br>c=10, B=35°, C=65%

NISA [10]

Answer:

Part 1) The measure of angle A is $A=80\°$

Part 2) The length side of a is equal to $a=10.9\ units$

Part 3) The length side of b is equal to $b=6.3\ units$

Step-by-step explanation:

step 1

Find the measure of angle A

we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

so

$A+B+C=180\°$

substitute the given values

$A+35\°+65\°=180\°$

$A+100\°=180\°$

$A=180\°-100\°=80\°$

step 2

Find the length of side a

Applying the law of sines

$\frac{a}{sin(A)}=\frac{c}{sin(C)}$

substitute the given values

$\frac{a}{sin(80\°)}=\frac{10}{sin(65\°)}$

$a=\frac{10}{sin(65\°)}(sin(80\°))$

$a=10.9\ units$

step 3

Find the length of side b

Applying the law of sines

$\frac{b}{sin(B)}=\frac{c}{sin(C)}$

substitute the given values

$\frac{b}{sin(35\°)}=\frac{10}{sin(65\°)}$

$b=\frac{10}{sin(65\°)}(sin(35\°))$

$b=6.3\ units$

For which of the following inequalities is x≥4 a solution.<br> x+3≥1<br> 3x≥1<br> x-3≥1

pychu [463]

Answer:

x - 3 ≥ 1

Step-by-step explanation:

Solving each of the inequalities

x + 3 ≥ 1 ( subtract 3 from both sides )

x ≥ - 2

3x ≥ 1 ( divide each inequality by 3 )

x ≥ $\frac{1}{3}$

x - 3 ≥ 1 ( add 3 to both sides )

x ≥ 4 ← required solution
