Answer:

x = -4

Step-by-step explanation:

[tex] - 3x = 12[/tex]

Lets divide both the sides by -3.

[tex] = > \frac{ - 3x}{ - 3} = \frac{12}{ - 3} [/tex]

[tex] = > x = - 4[/tex]

x= -4

-3x=12

divide x by -3 and do the same on the other side

12÷(-3)= -4

hence, x= -4

Answer:

10

Step-by-step explanation:

1/12 times 2 would be 1/6 miles per minute, so times that by 6 and it takes 6 minutes to run 1 mile. 60 minutes divided by 6 equals 10 miles per hour. Sorry if thats confusing

Answer:

None of these sound correct but I would say D

Step-by-step explanation:

The polygons are similar.

This is because dividing the corresponding sides forms the same ratio, as shown by the three equations below

35/28 = 1.25

25/20 = 1.25

(15.5)/(12.4) = 1.25

So the larger figure on the right has side lengths that are 1.25 times larger compared to the corresponding sides of the figure on the left.

You'll need to flip the figure on the left so that the side labeled "20" is along the top, and the "28" is along the bottom.

After this flip happens, also note that the angle arc markings match up. The bottom pairs of angles of each figure are shown with a single arc, while the top angles are shown as double arcs. This helps visually show which angles pair up and are congruent to one another.

Because we have similar proportions as discussed earlier, and congruent pairs of angles like this, this shows the two figures are similar quadrilaterals. The one on the right is simply an enlarged scaled up copy of the figure on the left.

Answer:

471.25

Step-by-step explanation:

A volume of a box is equal to length x width x height (abbreviated lwh). The given was: 14 & 1/2 inches long, 5 inches high, and 6 1/2 inches wide. So, all you have to do is multiply the given (I know it sounds too easy, but that's it):

14.5 * 5 * 6.5 = 471.25

So, the volume of the box is 471.25 inches cubed.

I hope that this helped & good luck!

Answer:

36 units²

Step-by-step explanation:

I used the triangles' area to find the area of the quadrilateral. The area of a triangle is 1/2 x base x height. The top triangle is 1/2 x 5 x 10 or 25. The bottom triangle is 1/2 x 2 x 11 or 11. Add 25 + 11 to get the total area.

Answer:

3in= 1/4 ft

Step-by-step explanation:

1 foot equals 12 inches so a quarter of 12 inches is 3. PLEASE MARK BRAINLIEST

Answer:

3 inches = 1/4 of a foot

Step-by-step explanation:

There are 12 inches in one foot, so we can create a quick proportion:

1 foot/12 inches = x feet/ 3 inches

x = 1/4 of a foot

================================================

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (8-6)/(2-5)

m = (2)/(-3)

m = -2/3

As you can see, we subtract the y coordinates together. We also subtract the x values together in the same order. If the order is mixed up, then you'll get the wrong sign for the final answer.

The slope is equal to rise over run. Think of "rise" as "change in y", which explains the difference in y values. The run is equal to the change in x, which is the difference in x values.

[tex]\boxed{\textsf{ The amount shared by Nandi is \textbf{ Rs 500. }.}}[/tex]

[tex]\boxed{\textsf{ The amount shared by Thabo is \textbf{ Rs 1,000. }.}}[/tex]

Step-by-step explanation:

Given that Nandini and Thabo share Rs 1500 in the ratio 1:2 . And we need to find how much each gets . So lets take the given ratio be 1x :2x . Now here we can find the share of both as ,

[tex]\qquad\boxed{\boxed{\sf Share =\dfrac{ Ratio \ number }{Sum \ of\ ratio\ nos. }\times Amount }}[/tex]

Hence here the sum of ratio numbers would be 1+2 = 3 . Here the ratio number of Nandi is 1 and that of Thaboo is 2 . So ,

Share of Nandi :-

[tex]\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Nandi)}= Rs\ 500 }}}[/tex]

[tex]\rule{200}2[/tex]

Share of Thabo :-

[tex]\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Thabo)}= Rs\ 1,000 }}}[/tex]

Answer:

A

Step-by-step explanation:

a) The length of shelf in centimeters is 72 cm

b) The length of shelf in metres is 0.72 m.

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

A shelf measures 720 mm long.

a) As 1 cm = 10 mm

So, the length of shelf in centimeters

= 720 /10

= 72 cm

b) As 1 m = 1000 mm

So, the length of shelf in meters

= 720 /1000

= 0.72 m
