Answer:

x = 8

Step-by-step explanation:

10/(3x+1) = 22/(7x-1)   ---->set up proportion

10(7x-1) = 22(3x+1) ----> cross multiply

70x - 10 = 66x + 22  --------> distribute

4x = 32

x = 8

5. Friday morning the Matthews family goes to town to buy groceries. The following three
sergij07 [2.7K]

Answer:

Step-by-step explanation:

Hello!

To compare different prices of several brands of a product the best is to express the price for the same quantities of product.

Since the three options are original in 300g, 450g and 600g, I'll express all prices on a base of 100g of product. You can use simple rule of three for this:

Option 1

300g cost $3.89

100g cost \frac{100*3.89}{300} = $1.296

Option 2

450g cost $ 4.77

100g cost \frac{100*4.77}{450}= $1.06

Option 3

600g cost $ 6.59

100g cost \frac{100*6.59}{600}= 1.098

So:

Option 1: $1.296/ 100g

Option 2: $1.06/100g

Option 3: $1.098/100g

The cheapest option is number 2

I hope this helps!

Find the surface area and round to the nearest hundredths place when necessary.
UNO [17]

Answer:

6 x 14 = 84

84 x 2(since there are two small rectangles) = 168

22 x 6 = 132

132 x 2 = 264

264 x 2(since there are two of the same shape) = 528

22 x 14 = 308

308  x 2(since there are two of the same shape) = 616

Now we add up all the areas:

168 + 528 + 616 = 1312 square cm is your answer.
