Solve for x. x - 8 / 2 = -3 A. 2 B. 7 C. –14 D. –9

2 answers:

8 0

For this question, you need to try all of the choices:
For A, we add x=2 and the equation would be 2 - 8 / 2 = -3, the real answer to that is: 2 - 8 / 2 = -3!
That means A is the correct answer and we don't have to try any of the other choices! Hope this helped >.<

Subtract x, giving you -8/2=-3-x. Multiply by 2, giving you -8=-6-2x. Add the 2x and the -8 to both side. This gives you 2x=-6+8. Reduce: 2x=2. Divide by 2, you are left with x=1. Using order of operations, that is the only solution that works, leaving all the multiple choice answers wrong.

Verdich [7]

Answer:

$297.41

Step-by-step explanation:

Given that:

Amount = 9270

Derferred period = 6 months = 0.5 yr

Rate = 17.95% = 0.1795

Amount = 9270(1 + 0.1795)^0.5

Amount = 9270(1.1795)^0.5

Amount = 10067.663

PV = 10067.663

Number of months, n = 48

Monthly amount to be paid :

rp = rate per period = 0.1795/12 = 0.0149583

(rp * PV) / 1 - (1 + rp)^-n

(0.0149583 * 10067.663) / 1 - (1 + 0.0149583)^-48

150.5951234529 / 0.5096723

= 295.47441

Closest option is $297.41

Answer:

$\frac{a(450-8a^2)}{4}$

is the volume in terms of side a

Step-by-step explanation:

Given that you I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per square foot, the material for the roof cost $2 per square foot, and the material for the sides cost $2.50 per square foot; and I spent $450 altogether on material for the shed.

Let a be the side of square and h be the height

Total cost of materials = cost for floor + cost for roof + cost for sides

= area of floor (4) + lateral area (2.50)+roof area (2)

$=4a^2+4ah+4a^2\\=8a^2+4ah = 450$ $h = \frac{450-8a^2}{4a}$
