4x = 5(x+2) -30
4x = 5x + 10 - 30
4x = 5x - 20
-x = -20
x = 20

Below are the supply and demand equations for umbrellas in a certain market. in these equations, p represents price, d represent

timurjin [86]

The value of price (p) at a point of equilibrium is 13.4. Then the correct option is C.

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The equation of the demand (D) and supply (S) is given below.

$\rm D = -\dfrac{4}{3}p +22\\\\S \ = 3p -36$

Where p is price.

At equilibrium, we have

D = S

Then

$\begin{aligned} \dfrac{4}{3}p +22 &= 3p -36\\\\3p + \dfrac{4}{3} p &= 36 + 22\\\\\dfrac{13}{3}p &= 58\\\\p &= 13.38 \approx 13.4 \end{aligned}$

More about the linear system link is given below.

Please help me it would mean a lot

42.5 i think

The whole angle is 127 minus the angle we know (32) this leaves us with 85 for the rest of the angle but we still have to deal with the angle bisector so we divide it by 2 leaving us with 42.5 I'm pretty sure.

A braid was bought to put around a blanket that measures 23 inches by 24 inches. At $0.60 per yard how much was paid for the bra

mojhsa [17]

To do this you need 94 inches of braid.

94 inches = ? yards

1 inch = 0.0277778 yard

94 × 0.0277778 = <span>2.6111132.

Since you can only pay for a full yard you would buy 3 yards which would cost:-

$0.60 </span>× 3 = $1.80.

So for this you would need 3 yards which would cost $1.80.

Hope I helped:P
