6x+3=45

6x+3-3=45-3

6x= 42

Divide by 6 for 6x and 42

6x/6= 42/6

x= 7

Check answer by using substitution method

6x+3= 45

6(7)+3= 45

42+3= 45

45= 45

The answer is x= 7

Answer:

6x +3 =45 (Being alternate angle)

Or, 6x= 45 - 3

or,6x = 42

or,x=42÷6

hence,x =7

From the diagram below, if side DF is 4 cm., side CB would be ______.

kondaur [170]

The measure of CB from the given figure is 8cm

<h3>What is a triangle?</h3>

A triangle is 2 dimensional shape with 3 sides and angles. The types of triangle that we have are;

Equilateral triangle
Scalene triangle
Isosceles

The given triangle is a scalene triangle since none of the sides are equal

From the figure shown, we can see that the measure of DF is equivalent to CE and EB

Since CB = CE + EB

Given the following parameter

DF = 4cm

CE = EB = DF = 4cm

Substitute

CB = 4cm + 4cm

CB = 8cm

Hence the measure of CB from the given figure is 8cm

Help ? I need steps on how to do this

Furkat [3]

Answer :- 

the quotient is ( 4x² - 5x + 7 )

Step-by-step explanation:

[ Refer to the attachment for steps ]

We have to eliminate the highest degree coefficient in each step.

And as in division of normal numbers we subtract the things here we do the same ,

but while subtracting we have to take care about the signs !

The negative sign changes the negative sign into positive sign and positive sign into negative sign.

Whereas , a positive sign don't changes the sign.

I need help plz.

viva [34]

Answer:

slope = $\frac{1}{2}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line

m = $\frac{6-0}{4+8}$ = $\frac{6}{12}$ = $\frac{1}{2}$
