Answer:

r<=-2

Step-by-step explanation:

-3(r-5)+7>=28

Distribute

-3r+15+7>=28

Then add like numbers

-3r+22>=28

subtract 22 from both sides

-3r>=6

Divide and when you divide/multiply a negative you flip the inequality sign

r<=-2

r≤−2

Step-by-step explanation:

-3(r-5)+7≥28

simplify

−3r+22≥28

-3r≥6

divide by -3, dividing by a negative switches the sign

r≤−2

A certain pizza parlor has 7<br> different toppings. How many two-<br> topping pizzas are possible?
Nezavi [6.7K]

Answer:

21

Step-by-step explanation:

Ok, so this may be confusing but I’ll explain.

Here is a very simplified diagram:

1-2, 1-3, 1-4, 1-5, 1-6, 1-7

2-3, 2-4, 2-5, 2-6, 2-7

3-4, 3-5, 3-6, 3-7

4-5, 4-6, 4-7

5-6, 5-7

6-7

*Note- I did this in about 30 seconds and on my phone so it is very simplified *

Each number, 1-7, is supposed to represent a different ingredient and they are put together to represent the two-ingredient combinations.

For example: 1-2 could represent pepperoni and sausage, and 1-5 could represent pepperoni and olives. This would mean that the 1 represents pepperoni, 2 represents sausage, and 5 represents olives.

If you count the number of combinations in each row, there are 21 combinations. This is because I made sure there are no repeats (2-3 AND 3-2) and because there wouldn’t be any doubles (1-1 or 2-2)

Brian read 8 1/4 pages of a book in 1/6 hour. At thus rate, what is the total number of pages if the book he will read in 1 hour
Oksana_A [137]
8 1/4 -> 1/6 hour
How many pages -> 1 hour?

You can use the cross multiply method
\frac{8 \ \:\frac{1}{4} \times 1 }{ \frac{1}{6} }


= 49.5 pages

Or you change the hours to minutes.
1/6 hour is 10 min.
[1/6 × 60 = 10 ]
Either way you'll get the same answer.

A shop sells cereal in boxes A, B and C. Box A 500 g for $1.73 Box B 750 g for $2.60 Box C 1.25 kg for $4.35. which box is the b
Hoochie [10]

Answer:

Box C

Step-by-step explanation:

First switch the box that's in kilograms into grams. One kilogram=1000 grams. So box C is 1250 grams.

Next divide the amount in each box by the cost of each box.

Box A 500/173=2.89

Box B 750/260=2.88

Box C 1250/435=2.87

So, since box C has the lowest amount when divided, that box has the best value.

<2 = <6(corresponding angle)

then <6 = 75°

now <6 = <7 (vertically opposite angle)

therefore, <7 = 75°
