For what value of c does the following system have no solution?<br><br> 1/2x+1/5y=2<br> 5x+2y=c

Minchanka [31]

Answer:

Step-by-step explanation:

$\frac{1}{2}x+\frac{1}{5}y = 2 \mid 5x + 2y = c$

First let's multiply the 1st equation by 10.

$5x + 2y = 20 \mid 5x + 2y = c$

So, we can see that the equations have the same coefficients and that implies they are equal.

So the equation has no solutions for. $c \in R \setminus{20}$

24= g/g +20. g/g is a fraction.

Stells [14]

Answer:

Subtract 20 from both sides.

24−20=9/g

2 Simplify 24-20 to 4

4=9/g

3 Multiply both sides by 9

4×9=g

4 Simplify 4×9 to 36

36=g

5 Switch sides.

Find the value of each variable using sine and cosine. Round your answers to the nearest tenth.

Alisiya [41]

Answer:

x ≈ 9.5 , y ≈ 15.3

Step-by-step explanation:

sin32° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{18}$ ( multiply both sides by 18 )

18 × sin32° = x , then

x ≈ 9.5 ( to the nearest tenth )

cos32° = $\frac{adjacent}{hypotenuse}$ = $\frac{y}{18}$ ( multiply both sides by 18 )

18 × cos32° = y , then

y ≈ 15.3 ( to the nearest tenth )
