Answer:

7 strips

Step-by-step explanation:

One way we can solve this is through guess and check. Let's start with 4 strips. If Joe's grandma makes 4 strips, she will have 0.75*4 = 3.00 yards of fabric. That's a really low amount of fabric. Let's double that to 8, where Joe's grandma would need 0.75*8 = 6.00 yards of fabric. That's really close! Let's remove one strip. 0.75*7 = 5.25 yards of fabric. Perfect! Joe's grandma can cut exactly 7 strips

Answer:

S_{n}<em> = n² + 4n ; n = 11 </em>

Step-by-step explanation:

S_{n} = \frac{n}{2} [2 a_{1} + (n - 1)d]

~~~~~~~~~

a_{1} = 5

d = 7 - 5 = 2

S_{n} = \frac{n}{2} [ 2(5) + 2(n - 1)] = \frac{n}{2} ( 8 + 2n ) = 4n + n²

S_{n}<em> = n² + 4n</em>

n² + 4n = 165

n² + 4n - 165 = 0

(n + 15)(n - 11) = 0 ( n ≥ 0 ) ⇒ <em>n = 11</em>

A community center sells a total of 305 tickets for a basketball game. An adult ticket costs ​$5. A student ticket costs ​$1. Th
julia-pushkina [17]

Answer: student tickets = 208

Adult tickets = 97

Step-by-step explanation:

x + y = 305

x = 305 - y

5x + y = 693

Substituting

5 (305 - y) + y = 693

1525 - 5y + y = 693

-4y = -832

y = 832 / 4 = 208
