Solve for x: 3|2x − 2| + 6 = 18. x = 3, x = −3
x = 3, x = −1
x = 1, x = −1
x = −3, x = 1

Answers

Answer 1
Answer:

Answer:

Option 2 - x = 3, x = −1

Step-by-step explanation:

Given : Expression 3|2x-2|+6= 18

To find : Solve the expression ?

Solution :

The expression gives an absolute function which means |a|=-a,a

Expression 3|2x-2|+6= 18

1) Taking3(2x-2)+6= 18

Solving,

6x-6+6= 18

6x= 18

x=(18)/(6)

x=3

2) Taking3(-(2x-2))+6= 18

Solving,

3(-2x+2)+6= 18

-6x+6+6= 18

-6x+12=18

-6x=6

x=-(6)/(6)

x=-1

Therefore, The solution of  3|2x-2|+6= 18is x=3,-1.

So, Option 2 is correct.
Answer 2
Answer: The answer is x=3, x= -1

Name the corresponding part if RST WXY.

∠ S =

Answers

Answer: ∠S = ∠X.

Step-by-step explanation:

Since we have given that

∠RST and ∠WXY

WE need to find the corresponding part of ∠S.

As we have given RST and WXY,

Corresponding part means a pair of matching sides or angles that are in the same side in two different shapes.

So,According to question,

Corresponding angle to ∠S is ∠X.

Hence, ∠S = ∠X.

The corresponding part is <X

In a collection of 1050 flowers, 3/10 of them are red , 2/5 of them arewhite and the rest are yellow. Find the no. of red, white and yellow flowers​

Answers

Answer:

315 red flowers

420 white flowers

315 yellow flowers​

Step-by-step explanation:

1050 flowers

3/10 of them are red=> 3/10 *1050=3*105=315 red flowers

2/5, (or 4/10),  are white =>4/10 * 1050=4*105=420 white flowers

=> 1050-(315+420)=1050-735=315 yellow flowers​

A bus and a car leave from the same city traveling in opposite directions. The bus leaves 2 hours before the car does. The bus travels at a steady speed of 50 mph while the car travels at 70 mph. After how many hours will the bus and car be 800 miles apart?If h represents the number of hours the bus travels, then which of the following expressions represents the number of miles the car travels?
70(h + 2)
70(h - 2)
70h

Answers

Answer:

After 7.8 hours (7 hours 48 min.) will the bus and car be 800 miles apart

70(h-2) expression represents the number of miles the car travels.

Step-by-step explanation:

If h represents the number of hours the bus travels.

In the question it is said that the bus leaves 2 hours before the car does

Therefore car travels (Time) = ( h-2 )

car's speed = 70 mph,

Distance = speed × time = 70(h-2)

70(h - 2) expression represents the number of miles the car travels.

If we want to find the number of hours will the bus and car be 800 miles apart we can solve it as :

50h + 70(h-2) = 800

50h + 70h - 140 = 800

120h = 800 + 140

120h = 940

h = 940 ÷ 120 = 7.833... = 7.8 hours (7 hours and 48 min.)

Ans. After the bus left the city, after 7.8 hours the car and the bus will be 800 miles apart.
the answer is b 70(h-2)
