Mathematics

Answer:

The amount of money A pays is \$51

Step-by-step explanation:

Let

x-----> amount of money A pays

y-----> amount of money B pays

we know that

x+y=85 ------> equation A

\frac{x}{y}=\frac{3}{2}

so

y=\frac{2}{3}x ------> equation B

substitute equation B in equation A and solve for x

x+(\frac{2}{3}x)=85

\frac{5}{3}x=85

x=85*3/5=\$51

8. Solve using any method.<br> 3y – 3 = 3x<br> -3x + 3y = -57
Ksivusya [100]

Answer:

No Solutions.

Step-by-step explanation:

I will solve your system by substitution.

3y−3=3x; −3x+3y=−57

Step: Solve 3y−3=3x for y:

3y−3+3=3x+3 (Add 3 to both sides)

3y=3x+3

(3y/3=3x+3)/3

(Divide both sides by 3)

y=x+1

Step: Substitute x+1 for y in −3x+3y=−57:

−3x+3y=−57

−3x+3(x+1)=−57

3=−57 (Simplify both sides of the equation)

3+(−3)=−57+(−3) (Add -3 to both sides)

0=−60

ryzh [129]

Answer:

<em>x = y = 64° , z = 20°</em>

Step-by-step explanation:

<em>x = y</em> = \frac{180-52}{2} <em>= 64 </em>°

m∠ADC = 52° + x

m∠ADC = 52° + 64° = 116°

<em>z</em> = 180° - 116° - 44° <em>= 20</em> °
