What is the solution of the linear equation -12+3b - 1 = -5 - b

Answers

Answer 1

Answer:

Answer:

The solution of the given linear equation is 2.

Step-by-step explanation:

$-12+3b - 1 = -5 - b$

Step 1 :Take all the like terms on same side

$-12+5 - 1 = - b- 3b$

Step 2 :

$-8=-4b$

Step 3 :

$b=(-8)/(-4)=2$

The solution of the given linear equation is 2.

Answer 2

Answer:
$- 12 + 3b - 1 = - 5 - b \n \n - 13 + 3b = - 5 - b \n \n - 8 = - 4b \n \n b = 2$

First, add both sides by 5 and then subtract both sides by 3b

If i buy 4 cans of soup for $6.00 which proportion can be used to find the cost of 13 cans

Answers

Final answer:

The cost of 13 cans of soup, given that 4 cans cost $6.00, can be determined using a proportion. The proportion is set up as 4 cans / $6.00 = 13 cans / x, which Solving for x indicates that the cost for 13 cans of soup is $19.50.

Explanation:

The question is asking for the cost of 13 cans of soup, given that 4 cans cost $6.00. This can be solved using a proportion. A proportion is set up as an equivalent fraction equation, where the ratio of the number of cans to the cost is equal in both situations. Here, the proportion is 4 cans / $6.00 = 13 cans / x, where x is the cost we are trying to find for 13 cans of soup.

To solve for x, we would use cross-multiply. This gives us 4x = 78, where we then divide both sides by 4 to get x = $19.50. So, the cost of 13 cans of soup is $19.50.

How many inches are in 5 1/2 yards

Answers

How many inches are in 5 $(1)/(2) yards?$
There are 3 feet in a yard
There are 12 inches in a foot
$5 (1)/(2) = (11)/(2)$
You must multiply $(11)/(2)$ yards by feet
$(11)/(2)$ × $(3)/(1)$ = $(33)/(2)$
You must multiply $(33)/(2)$ by inches per foot
$(33)/(2)$ × $(12)/(1)$ = $(396)/(2)$
You must divide the numerator(top) by the denominator(bottom) to simplify
396÷2=198
There are 198 inches in $5 (1)/(2) yards$
