Answer:

Step-by-step explanation:

x^2=3x-2(subtract 3x and add 2) x^2-3x+2=0(group) (x-1)(x-2)=0(find x) x=1;x=2

find y values for x values and check:

1^2=1, pair 1:(1,1); 3(1)-2=3-2=1, same pair

2^2=4, pair 2:(2,4); 3(2)-2=6-2=4, same pair

pairs: (1,1);(2,4)

Solve for m:3m\5+a=b

Shalnov [3]

Step-by-step explanation:

Assuming:

$\frac{3m}{5} + a = b$

subtract a from both sides

$\frac{3m}{5} = b - a$

multiply both sides by 5

$3m = 5(b - a)$

divide both sides by 3

$m = \frac{5(b - a)}{3}$

____________________

if,

$\frac{3m}{5 + a} = b$

multiply both sides by (5+a), then divide both sides by 3

$m = \frac{b(5 + a)}{3}$

PLEASE HELP!

Novosadov [1.4K]

Answer: 25,0.

Step-by-step explanation:

∡B=27° ∡C=82° b=12 a=?

∡A=180°-(27°+82°)=180°-109^°=71°.

$\frac{a}{sinA} =\frac{b}{sinB} \\a=\frac{b*sinA}{sinB}=\frac{12*sin71^0}{sin27^0}=\frac{12*0,9455}{0,454} \approx25,0$
