Answer:

x= -1/4

Step-by-step explanation:

The value of x is -1/4 in the given equation 1=4x+2.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 1=4x+2

One equal to four times of x plus two

In the given equation x is the variable and plus is the operator.

1=4x+2

Subtract 2 from both sides to isolate the x term

1-2=4x

-1=4x

Divide both sides by 4

x=-1/4

Hence, the value of x is -1/4 in the given equation 1=4x+2.

Answer:

56in³

Step-by-step explanation:

you can make an imaginary division and create two different prisms. the bigger prism's volume is 4×3×4=48 and the smaller prism's volume is 4×2×1=8. add up the product to get total volume of 56in³ (³ because it is volume and not area)

Answer:

C (3, 1 )

Step-by-step explanation:

To determine if a point lies on the line, substitute the x- coordinate of the point into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line, otherwise not on line.

A (4 , - 3)

y = - 2(4) + 5 = - 8 + 5 = - 3 ← lies on line

B (- 2, 9 )

y = - 2(- 2) + 5 = 4 + 5 = 9 ← lies on line

C (3, 1 )

y = - 2(3) + 5 = - 6 + 5 = - 1 ≠ 1 ← not on line

D (- 1, 7 )

y = - 2(- 1) + 5 = 2 + 5 = 7 ← lies on line

E (2, 1 ) = - 2(2) + 5 = - 4 + 5 = 1 ← lies on line

Thus (3, 1 ) does not lie on the line → C

Answer:

7 runners

Step-by-step explanation:

In order to figure this question out, you need to count them up. Count up all the runners that are plotted from 3 miles on. Anything before that is under 3 miles, so it doesn't count.

After counting them up, you will find that there are 7 runners marked who ran 3 miles or more. So your answer is 7 runners.

Answer:

I think the answer is 120 days

Step-by-step explanation:

After 120 days, population will be 10000 times 3 which is equal to 30000

After another 120 days, population will be 30000 times 3 which is equal to 90000 and 90000 is under 100000

hence after 240 days, the population will still stay under 100000

Answer:

Answer:

where's the question 0.0

Answer:

Step-by-step explanation:

1 meter = 1000 mm

So, 1 mm = [tex]\frac{1}{1000}[/tex] m

To change mm to meter, divide the given mm value by 1000

Ex: 50 mm = 50 ÷ 1000 = 0.05 m

       5 mm = 5 ÷ 1000 = 0.005

Answer:

To convert millimeters to meters, multiply the number of millimeters by 0.001.

To convert meters to millimeters, multiply the number of meters by 1000.

Step-by-step explanation:

1 millimeter is 0.001 meters.

1 meter is 1000 millimeters.

To convert millimeters to meters, multiply the number of millimeters by 0.001.

Example:

This object is 100 millimeters long. How many meters long is it?

100 x 0.001 = 0.1

0.1 meters.

To convert meters to millimeters, multiply the number of meters by 1000.

Example:

This object is 100 meters long. How many millimeters long is it?

100 x 1000 = 100000

100000 millimeters.

Answer:

Option c : 32 degree.

Step-by-step explanation:

2x + 2x + 14 + 6x + 6 = 180 degrees

10x = 160

x = 16

2x = 16 *2 = 32 degrees

Answer:

Step-by-step explanation:

Angles in a triangle add up to 180°

You take 2x+2x+14+6x+6=180°

Collect like term and add 2x+2x+6x+14+4=180°

10x+20=180°

10x=180°-20

10x=160÷10

x=16

16*2=32

16*2+14=46

16*6+6=100

Smallest angle is 32

Answer: There are 72 pond critters  in the aquarium. There are 24 caddis fly larvae, 18 tadpoles, 12 diving beetles and 12 whirligig  beetles in the aquarium.

Step-by-step explanation:

Given :  There are caddis fly  larvae, diving beetles, whirligig beetles, dragonflies and tadpoles in the aquarium

One-twelfth of the pond animals are dragonflies

One-third of the  animals are caddis fly larvae.

One-fourth are tadpoles.

The same number of  diving beetles as whirligig beetles.

Number of dragon flies = 6

Let the total animals are = x, dragon flies are represented by d , caddis fly larvae as c, tadpoles as t , diving beetles as b and whirligig beetles as w.

Now : x = d + c + t+ b + w

[tex]\frac{1}{12}\times x=d[/tex]    (1)

[tex]\frac{1}{3}\times x=c[/tex]    (2)

[tex]\frac{1}{4}\times x=t[/tex]   (3)

[tex]b=w[/tex]      (4)

[tex]d=6[/tex]       (5)

Comparing 1 and 5

[tex]\frac{1}{12}\times x=6////x=72[/tex]

Thus pond critters are 72.

[tex]c=\frac{1}{3}\times 72=24[/tex]

[tex]t=\frac{1}{4}\times 72=18[/tex]  

[tex]d=6[/tex]

Now x = d + c + t+ b + w

72 = 6+24+18+b+b   (as b= w)

2b =24

b = 12

Thus w = 12.
