Solve for x. 3(2x-3) +42-2=0

Mathematics
1 answer:
baherus [9]3 years ago
6 0

Answer:

x = -31/6 or -5.16

Step-by-step explanation:

3(2x-3) + 49 -2 = 0

Distribute 3 through the parenthesis

3 (2x-3) + 49 - 2 = 0

6x - 9 + 42 - 2 = 0

Calculate the sum or difference

6x - 9 + 42 - 2 = 0

6x + 31 = 0

Move constant to the right side and change its sign

6x + 31 = 0

6x = -31

Divide both sides of the equation by 6

6x = -31

x = -31/6 or -5.16

Solutions 

We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × <span>(Side A + Side B). 
</span>
We have the side lengths 7.7 mm and 17.2 mm. 

Solve 

2 × <span>(Side A + Side B) 
2 </span>× <span>( Side A (7.7) + Side B (17.2) )  
</span>= (7.7 x 2) + (17.2 x 2) 
= 49.6

<span>The perimeter is 49.6 mm².  </span>

mr henderson mixed 3.732g of chemical A, 13.902 of chemical B and 5.208g of Chemical C to make 3 does of medicine, About how muc
Dafna11 [192]

Answer:

22.8 grams

Step-by-step explanation:

To find total amount of medicine, we have to add all the 3 quantities of Chemical A, Chemical B, and Chemical C.

Before we do that, we have to round up each quantity to the nearest tenths.

Nearest tenths means we can take "1 digit" after the decimal point. For that we use rounding rules.

If the 2nd digit to the right of decimal is 5 or greater, we round up the 1st digit to the next whole number. If the 2nd digit is less than 5, we keep the 1st digit same.

So, using that we round up each of the three numbers as shown:

3.732 becomes 3.7 (since 3 is less than 5, we keep the 7)

13.902 becomes 13.9 (since 0 is less than 5, we keep 9)

5.208 becomes 5.2 (since 0 is less than 5, we keep 2)

Now we add:

3.7 + 13.9 + 5.2 = 22.8 grams
