Solve for x<br><br> (1.) 5/10x-9=8<br><br> (2.) 3/4x-3=1+5/12x

Yakvenalex [24]

Answer:

1). $x=\frac{5}{170}$

2). $x=\frac{1}{12}$

Step-by-step explanation:

(1.) $\frac{5}{10x}-9=8$

adding 9 on both sides we get

$\frac{5}{10x}=9+8$

$\frac{5}{10x}=17$

$5=17 \times 10x$

$x=\frac{5}{170}$

(2.) $\frac{3}{4x}-3=1+\frac{5}{12x}$

$\frac{3}{4x}-\frac{5}{12x}=1+3$

$\frac{9-5}{12x}=4$

$\frac{4}{12x}=4$

$12x=1$

$x=\frac{1}{12}$

You are filling paper cones with popcorn for a party.

Sunny_sXe [5.5K]

Answer:

The amount of popcorn needed to fill the paper cone is $V=1,005\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

In this problem we have

$r=8\ cm$

$h=15\ cm$

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(8)^{2}(15)$

$V=1,005\ cm^{3}$

4x + 5y = 22<br> 7x - 3y = -32

lana66690 [7]

Answer:

x = -2

y = 6

Step-by-step explanation:

i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out

12x + 15y = 66

+ <u>35x - 15y = -160</u>

47x = -94

x = -94/47

x = -2

substitute -2 for 'x' to solve for 'y':

4(-2) + 5y = 22

-8 + 5y = 22

5y = 30

y = 6
