Gx = 45 + 9x what is x

1 answer:

4 0

$Gx=45+9x\ \ \ \ \ |subtract\ 9x\ from\ both\ sides\\\\Gx-9x=45\\\\x(G-9)=45\ \ \ \ |divide\ both\ sides\ by\ (G-9)\\\\\boxed{x=\dfrac{45}{G-9}}$

Tanya [424]

Answer:

Obtuse

Step-by-step explanation:

x = missing angle

20+30+x=180

50+x=180

x=130

90<130

Thus, the triangle is obtuse

Answer:

203in²

Step-by-step explanation:

split up the shape into three rectangles

5in × 14in = 70

9in × 7in = 63

5in × 14in = 70

70 + 63 + 70 = 203in²

I need help! Will mark Brainliest for full answer!!!

Fed [463]

Answer:

Part 1) $x=11$

Part 2) $k=57.2$

Part 3) $y=9.2$

Part 4) $x=2.375$

Part 5) $y=3.3$

Part 6) $k=6.7$

Part 7) $k=115.2$

Part 8) $y=1.4$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Part 1) y varies inversely with x. If y = 3 and k (the constant of variation) = 33, what is x?

we have

$y*x=k$

$y=3$

$k=33$

substitute and solve for x

$3*x=33$

Divide by 3 both sides

$x=33/3$

$x=11$

Part 2) y varies inversely with x. When y = 11, x = 5.2. What is the value of k, the constant of inverse variation?

we have

$y*x=k$

$y=11$

$x=5.2$

substitute and solve for k

$11*5.2=k$

$k=57.2$

Part 3) y varies inversely with x, and k (the constant of variation) = 72. What is the value of y when x = 7.8?

we have

$y*x=k$

$x=7.8$

$k=72$

substitute and solve for y

$y*7.8=72$

Divide by 7.8 both sides

$y=72/7.8$

$y=9.2$

Part 4) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

we have

$y*x=k$

$y=8$

$k=19$

substitute and solve for x

$8*x=19$

Divide by 8 both sides

$x=19/8$

$x=2.375$

Part 5) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?

we have

$y*x=k$

$x=7$

$k=23$

substitute and solve for y

$y*7=23$

Divide by 7 both sides

$y=23/7$

$y=3.3$

Part 6) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?

we have

$y*x=k$

$y=6.7$

$x=1$

substitute and solve for k

$6.7*1=k$

$k=6.7$

Part 7) y varies inversely with x. When y = 9.6, x = 12. What is the value of k, the constant of inverse variation?

we have

$y*x=k$

$y=9.6$

$x=12$

substitute and solve for k

$9.6*12=k$

$k=115.2$

Part 8) y varies inversely with x, and k (the constant of variation) = 5.6. What is the value of y when x = 4?

we have

$y*x=k$

$x=4$

$k=5.6$

substitute and solve for y

$y*4=5.6$

Divide by 4 both sides

$y=5.6/4$

$y=1.4$

Melissa collected 14 bottles on Saturday and 9 bottles on sunday for recycling. on monday, she took all the bottles to the recyc

lina2011 [118]

Answer:

Option B is correct that is the amount she is getting per bottle is $0.15

Step-by-step explanation:

We have been given the information that Melisande collected 14 bottles on Saturday and 9 bottles on Sunday

That means she has collected a total of 23 bottles

Let us assume that the amount she is paid for recycling is $b

Since she is left with $3.20 after the amount she gets for bottles we will get the equation below:

23b=3.20

Now, since she has to pay a one-time service fee equation will become

23b -0.25 =3.20

After simplification, we will get

23b=3.20+0.25=3.45

b=3.45/23=.15

b=$0.15

Therefore, The amount she is getting per bottle is $0.15

HOPE THIS HELPS :)
