$4n-15+3n=90\\
7n=105\\
n=15\\\\
\angle LQK=4\cdot15-15=60-15=45^{\circ}$

3n+(4n-15)=90

3n+4n-15=90

7n=105

n=105/7

n=15

---------------------

Angle LQK is 4n-15

If n=15

Angle LQK = 4(15) - 15

= 60 - 15

= 45

A corner store sells two kinds of baked goods: cakes and pies. A cake costs $10 and a pie costs $7. In one

Ede4ka [16]

I think the answer would be 4 cakes because they would have bought 6 pies for it to cost $42 and then the extra $40 which will be converted to 4 cakes. So the answer is 4. Hope I helped.

Work out the equation of<br> the line that goes through<br> (3, 2) and (-1, 10)

Natali5045456 [20]

Answer:

$The\,\,equation\,\,will\,\,be\,\,2x+y=8$

Step-by-step explanation:

Let, A=(3,2)

B=(-1,10)

So, The equation will be

$\frac{x-x_{1} }{x_{1} -x_{2} } =\frac{y-y_{1} }{y_{1} -y_{2} } \\=>\frac{x-3 }{3-(-1) } =\frac{y-2 }{2-10} \\=>\frac{x-3 }{4} =\frac{y-2 }{-8}\\=>-8x+24=4y-8\\=>8x+4y=32\\=>2x+y=8$
