Answer:

\huge{x =  \frac{236164}{9477}  = 24 \frac{8716}{9477}}

Step-by-step explanation:

(81) - 4 \div (729)2 - x =  \frac{9}{4} x

81 -  \frac{4}{729}  \times 2 - x =  \frac{9}{4} x

81 -  \frac{8}{729}  - x =  \frac{9}{4} x

\frac{59041}{729}  - x =  \frac{9}{4} x

236164 - 2916x = 6561x

- 2916x - 6561x =  - 236164

- 9477x =  - 236164

\boxed{\green{x =  \frac{236164}{9477}  = 24 \frac{8716}{9477}}}

△FSB∼△ZDR .
Leya [2.2K]

Answer:  22 units.

Step-by-step explanation:

Here FSB and ZDR are two triangles.

In which, FS = 38 unit, FB = 55 unit, ZD = 15.2 unit and ZR = x unit.

Also, \triangle FSB\sim \triangle ZDR

Thus, By the property of similarity,

\frac{FS}{ZD} = \frac{FB}{ZR}

⇒ \frac{38}{15.2} = \frac{55}{x}

⇒ x = \frac{55\times 15.2}{38}

⇒ x = \frac{836}{38}

⇒ x = 22

Thus, ZR = 22 unit.

A line passes through (1, –5) and (–3, 7).
son4ous [18]
A.  First, find the slope, which  is -0.5, and then insert it into point-slope form, which is y-y1=m(x-x1), or y-1=-0.5(x+5). That's point-slope form.


B.  First, distribute -0.5 to both terms  in the parenthesis, to get y-1=-0.5x-2.5, and lastly add 1 to both sides to get the slope-intercept form of y=-0.5x-1.5

At the market, 2.4 pounds of carrots cost $1.68 and 1.8 pounds of broccoli cost $1.53. How much more does 1 pound of broccoli co
Greeley [361]

For calculating that, you have to find the unit rate first;

2.4 pound carrot = $1.68

1 pound carrot = $1.68/2.4 = $0.7

1.8 pound broccoli = $1.53

1 pound broccoli = $1.53/1.8 = $0.85

So, it would be = $0.85 - $0.7 = $0.15

SO, YOUR ANSWER IS $0.15

Andy cut rope for an activity at outdoor camp. He had 504 centimeters of rope to cut into equal-length pieces. How many of the w
mina [271]

Answer: B, C, E

Step-by-step explanation:

For us to know if the options are correct, we just have to multiply the length the rope was cut into by the number of pieces and check if it equals 504 centimeter.

A. 12 pieces of 42.3 centimeter long rope.

= 12 × 42.3

= 507.6

This is wrong

B. 15 pieces of 33.6 centimeter long rope

= 15 × 33.6

= 504cm

This is correct

C. 16 pieces of 31.5 centimeter long rope

= 16 × 31.5

= 504cm

This is correct

D. 20 pieces of 25 centimeter long rope

= 20 × 25

= 500cm

This is incorrect

E. 35 pieces of 14.4 centimeter long rope

= 35 × 14.4

= 504cm

This is correct

Therefore, the correct option are B, C and E.
