-3-3x=-4(2x+7) solbe

Answer:

x = -5

Step-by-step explanation:

-3 - 3x = -4( 2x + 7 )

Distributive property

-4 * 2x - 4 * 7

-3 - 3x = -8x - 28

Add 3 on both sides

-3 + 3 - 3x = -8x - 28 + 3

-3x = -8x - 25

Add 8x on both sides

-3x + 8x = -8x + 8x - 25

5x = -25

Divide by 5 on both sides to isolate the variable

5x/5 = -25/5

x = -5

Hope this helped!

Answer:

x = -5

Step-by-step explanation:

Rearrange terms

-3−3=−4(2+7)

−3−3=−4(2+7)

Distribute

−3−3=−4(2+7)

−3-3=−8−28

Add 3 to both sides of the equation

−3−3=−8−28

−3−3+3=−8−28+3

Simplify

Add the numbers:

−3−3+3=−8−28+3

−3=−8−28+3

Add the numbers:

−3=−8−28+3

−3=−8−25

Add 8 to both sides of the equation

−3=−8−25

−3+8=−8−25+8

Simplify

Combine like terms

−3+8=−8−25+8

5=−8−25+8

Combine like terms

5=−8−25+8

5=−25

Divide both sides of the equation by the same term

5=−25

5x/5 = -25/5

Simplify

Cancel terms that are in both the numerator and denominator

5x/5 = --25/5

x= -25/5

Divide the numbers

x= -25/5

x = -5

4. Can two lines be parallel and perpendicular? Explain.
lidiya [134]

Answer: No

Step-by-step explanation: First, we need to understand that parallel lines are coplanar lines that do not intersect. On the other hand, perpendicular lines are lines that intersect at a right angle.

However, lines can't be both parallel and perpendicular because they either intersect each other at a right angle or never intersect.

So no, two lines can't be both parallel and perpendicular.

A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost?
Aleks04 [339]
Set up an algebraic equation: b=cost of ball
1.10=1+b+b
1.10=1+2b
subtract 1 from both sides
.10=2b
divide by 2 on both sides
ball=5 cents
