Answer: I think it goes like this im pretty sure ;)

Distribute

q+12-2q+44>0

Combine like terms

-q+56>0

Subtract 56 from both sides

-q>-56

Multiply both sides by -1 (flip the inequality sign)

q<56

The Final answer: q<56

The coffee merchant plans to mix some fancy $6.50 per pound ground coffee called royal soil with 10 pounds of a lowly $2 per pou

taurus [48]

Answer and explanation:

Given:

Royal soil= $6.50 per pound

Royal peasant = $2 per pound of 10 pounds

Blend total pounds is x+10, price is unknown hence solved below

Using algebra

We find unknown x = number of pounds of royal soil

$6.50(x)+$2(10)=6.50x+20/x+10(x+10)

= 6.50x+20= 6.50x²+85x+200

About how wide is this house?

AURORKA [14]

Answer:

The house is 37.37 feet wide.

Step-by-step explanation:

See the diagram attached to this question.

We know, the formula from properties of triangle that

$\cos A = \frac{b^{2} + c^{2} - a^{2}}{2bc}$

Here we assume that A = 65°, b = 26 feet and c = 40 feet and we have to find a = x feet.

So, using this above formula, we can write

$\cos 65 = \frac{26^{2} + 40^{2} - x^{2}}{2\times 26 \times 40}$

⇒ $26^{2} + 40^{2} - x^{2} = 2 \times 26 \times 40 \cos 65 = 879$

⇒ $x^{2} = 26^{2} + 40^{2} - 879 = 1396.95$

⇒ x = 37.37 feet.

Therefore, the house is 37.37 feet wide. (Answer)
