$25-[2+5y-3(y+2)]=-3(2y-5)-[5(y-1)-3y+3] \\ 25-[2+5y-3y-6]=-6y+15-[5y-5-3y+3] \\ 25-2-5y+3y+6=-6y+15-5y+5+3y-3 \\ -2y+29=-8y+17 \\ 6y+29=17 \\ 6y=-12 \\ y=-2$
Hope this helped :)

9. Find the measure of angle<br> a.<br> a<br> 36°<br> 57°

sammy [17]

A is equal to 87 degrees. You get this answer since all triangle angle measurements must equal 180 when combined. So you add
36+57=93
180-93=87
A=87

forest ranger christ johnson at ranger station a sights a fire in teh direction 32 east of north. ranger rick thorpe at ranger s

RoseWind [281]

Answer: 8.6 from Ranger Christ and 6.8 from Ranger Rick

Step-by-step explanation:

The sides of triangle with A point as Ranger christ, B point as Ranger rick and C point at which two fires intersect.

This can be better understood by using law of sines

$\frac{sin(90-32)}{a}$ = $\frac{sin(90-48)}{b}$ = $\frac{sin(180-58-42)}{10}$

Solving we get

a= 8.6

and b= 6.8

Solve the formula A=10+ry. solve for y

noname [10]

The given formula $A= 10 + ry$

Solve for y means we have to make y alone

$A= 10 + ry$ \\

Add -10 on both sides, we get

$A - 10 = 10 -10 + ry \\A - 10 = 0 + ryA - 10 = ry$

As there is multiplication sign between r and y so to solve for y, divide both side by r

$\frac{A - 10}{r} = y\\\\y = \frac{A - 10}{r}$
