Solve each equation check your solution 2(3b-1)=40

vitfil [10]

Answer:

b=7

Step-by-step explanation:

2(3b-1)= 40

divide both sides by 2

3b-1 = 20

then add 1 to each side

3b = 21

then divide both sides by 3

b = 7

then check 2(3*7-1) = 40

8 * 5/7 equalfind the product write the product in its simplest form 8 * 5/7

Naily [24]

The product of 8 and 5/7 is 5.7

Step-by-step explanation:

The given product is $8 \times 5/7$ .

In the product, two terms are given :

The first term 8 is a whole number.
The second term 5/7 is a fraction.

1) So, to find the product of the first term and the second term, one method is to simplify the fraction into decimal number and then perform multiplication operation.

2) Either you can multiply the two terms in the first step and then the division operation is performed at the final step.

First method :

Step 1 : Convert the fraction into decimal

⇒ 5/7 = 0.71

Step 2 : Multiply the result with the other term.

⇒ 8 × 0.71

⇒ 5.68 (approximately 5.7)

Second method :

Step 1 : Multiply both the terms

⇒ 8 ×(5/7) = 40/7

Step 2 : divide 40 by 7

⇒ 40÷ 7 = 5.7

Therefore, the product of 8 and 5/7 is 5.7

Carlos is tiling a kitchen cluster that is 12 feed by 3 feed. The counter has a rectangular hole 3 feet by 2 feet cut in ir for

Taya2010 [7]

Answer:

The area of the counter that Carlos will wall tile is $30 ft^{2}$

Step-by-step explanation:

to solve this, we will calculate the area of the counter and the area of the rectangular hole that Carlos would have to leave out for the sink, and then subtract them to get the area that will be tiled.

Total area of the rectangular counter = length X breadth = $12 \times 3 = 36ft^{2}$

area of the rectangular cut out for the sink = length X breadth = $3 \times 2 = 6 ft^{2}$

Surface area that Carlos is meant to tile = $36ft^{2}- 6 ft^{2} = 30ft^{2}$

Hence,the area of the counter that Carlos will wall tile is $30 ft^{2}$
