Answer:

b=15

How I got it:

32 + (7x4) = 32 + 28 = 60

60 divided by 4 = 15

Checking:

15 - 7 = 8

8 x 4 = 32

32 = 32

You can tell b = 15 is the correct answer.

Jerome will also order t-shirt for the volunteer he will order both adults and child t-shirt . Adults t-shirt are $5 child t-shi

Gala2k [10]

Answer:

$A\geq 200...(1)$

$5A+2.50C\leq 1500...(2)$

Step-by-step explanation:

Let A represent number of adult t-shirts and C represent number of child t-shirts.

We have been given that adults t-shirt are $5 child t-shirt are $2.50, so cost of A adult t-shirts would be $5A$ and cost of C child t-shirts would be $2.50C$ .

We have been given that Jerome need at least 200 adults t-shirt. This means the number of adult t-shirts should be greater than on equal to 200.

We can represent this information in an inequality as:

$A\geq 200...(1)$

We are also told that Jerome will spend no more than $1500 on t-shirt. This means that cost of A adult t-shirts and C child t-shirts should be less than or equal to 1500.

We can represent this information in an inequality as:

$5A+2.50C\leq 1500...(2)$

Therefore, our required system of inequalities would be:

$A\geq 200...(1)$

$5A+2.50C\leq 1500...(2)$

HELP PLEASE!!! Ashton drew a triangle with vertices A (-1,2), B (5,2) and C (5.-1). He then rotated the triangle 180°

Naddika [18.5K]

Answer: The rule is when rotating 90 degrees, it's (-y, x), 180 degrees is (-x, -y), and 360 degrees is (y, -x). Just plug in the numbers accordingly, and you should get the correct answer. It worked for me <3.
