Answer:
Style A shoes sold : <u>152</u>
Style B shoes sold : <u>88</u>
Step-by-step explanation:
Let :
- Style A shoes = x
- Style B shoes = y
Forming equations :
- x = 2y - 24
- 66.95x + 84.95y = 17,652
Substitute the value of x from 1 in 2.
- 66.95 (2y - 24) + 84.95y = 17,652
- 133.90y - 1606.80 + 84.95y = 17,652
- 218.85y = 19258.80
- <u>y = 88</u>
<u />
Finding x :
- x = 2(88) - 24
- x = 176 - 24
- <u>x = 152</u>
<u />
Solution :
- Style A shoes sold : <u>152</u>
- Style B shoes sold : <u>88</u>
(N-2)*180/n
Octagon has 8 sides
(8-2)*180/8
=135
Answer:
It's choice 2.
Step-by-step explanation:
The nth value is 1 more than twice the previous value
- for example, 15 = 2*7 + 1.
Answer:
- B.
.
Step-by-step explanation:
<u>Step 1:</u>
<u>Step 2:</u>
<u>Step 3:</u>
- Factoring

- The first term is,
its coefficient is 1 . - The middle term is, -p its coefficient is -1 .
- The last term, "the constant", is +11
- Step-1 : Multiply the coefficient of the first term by the constant 1 • 11 = 11
- Step-2 : Find two factors of 11 whose sum equals the coefficient of the middle term, which is -1 .
- -11 + -1 = -12
- -1 + -11 = -12
- 1 + 11 = 12
- 11 + 1 = 12
-
- Observation : No two such factors can be found !!
- Conclusion : Trinomial can not be factored
