- 3(x - 7) + 2 = 20 I need help to solve it​

Answers

Answer 1
the answer is
X=1

-3(x-7)+2=20
-3x + 21 + 2 = 20
-3x + 23 = 20
-23. -23
-3x=-3
Divide by -3
X=1
Answer 2

Answer:

x=1

Step-by-step explanation:

First you will distribute it

U basically multiply the 3 by the X and the 7 here

-3 x (x = -3x And the 7 becomes a 21

Then you add the 2

21 + 2 = 23

Then you add the -3

-3x + 23 =20

Then using the equation above you subtract 23 from both sides

(-3 + 23) - 23 = 20 - 23

Then you simplify it

-3x = -3

Then you divide them using the same term

  -3

÷ -3

Then you simplfy it and you get

x=1

Step-by-step explanation:

Use sine

Sine 73 = x / 38

Sine of 73 is 0.956

Which means

0.956 = x / 38

Multiply 38 on both sides

36.328 = x

Answer:

b = 12.6

Step-by-step explanation:

36 + b*2 = 196

Subtract 36 from both sides

36 + b*2 = 196

-36             -36

b*2 = 160

Find the square root of both

Car A travels 20 mph faster than Car B. In the same time that Car A travels 208 mi, Car B travels 156 mi. Find their speeds. The speed of Car A is and the speed of Car B ​

Answers

Step-by-step explanation:

Assuming the speed of car B to be x and the speed of car A to be x+20

156 = 208

x. x+20

156(x+20)= 208x

156x+3120=208x

3120=208x-156x

3120=52x

x=60

The speed of car A is (x)= 60

The speed of car B is(x+20)= 80

Answer:

[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]

Step-by-step explanation:

Answers

the answer is 33.3% , hope this helps :)

Answer:

A. 33.3%

Step-by-step explanation:

On a dice, we have the numbers 1, 2, 3, 4, 5, and 6. The question is asking for the probability of anything greater than 4. This means we're trying to find the probability of rolling a 5 or a 6 since those are the only numbers greater than 4 on a dice. We can write this as a fraction.

There are six numbers total, so that will be the bottom of our fraction. We have two numbers that are greater than 4. This means we will write our fraction like so:

[tex]\frac{2}{6}[/tex]

Next, we can simplify the fraction by 2, leaving us with 1 over 3, like this:

[tex]\frac{2}{6} = \frac{1}{3}[/tex]

Finally, just divide the 1 by 3 to get 0.333, or 33.3% when you move the decimal two places to the right. Hope this helps!
