Can a triangle be formed with side lengths 15, 20, and 24? Explain.

Answers

Answer:

Yes

Step-by-step explanation:

The sum of two numbers is 25 and their difference is 13. Find their product.

Answers

Step-by-step explanation:

x + y = 25

x - y = 13

x.y = ?

x + y = 25

y = 25 - x

x - y = 13

x - 25 + x = 13

2x = 13 + 25

2x = 38

x = 38/2

x = 19

y = 25 - x

y = 25 - 19

y = 6

(x, y) = (19,6)

So, find their product!!

= x.y

= 19 × 6

= 114

PLEASE HELP WILL MARK BRAINLIEST!!!!

Answers

Answer:

y = -5x + 20

Step-by-step explanation:

Lets start with the first given values for x and y

(2,10)

Lets try out the first equation

y = 5x + 4

y = 5(2) + 4

y = 14

This equation wouldn't work because the y value is not 10 when the x value is 2

y = 5x + 20

y = 5(2) + 20

y = 30

This equation doesn't work either

y = -5x + 20

y = -5(2) + 20

y = -10 + 20

y = 10

This would be the correct equation since your y value is 10 when the x value is 2

Answer:

y = -5x + 20

Step-by-step explanation:

(2,10) and (3,5)

Slope = (y-y)/(x-x)

(10-5)/(2-3) = 5/-1 = -5

y-intercept (any point) = y - (slope times x)

y-intercept = 5 - (-5)(3) = 5 + 15 = 20

Answers

Answer:

solve it

Step-by-step explanation:

X+X=25-13

Answer:

114

Step-by-step explanation:

Let x+y=25

Let x-y=13

Let's isolate one variable

x-y=13 can be re-written as x=13+y

Now that we isolated x we can replace it in the other equation

(x)+y=25

(13+y) +y=25

13 +2y=25

-13           -13

2y=12

12/2=6

We know that y=6

Let's replace y with 6 to find x

x+(y)=25

x+6=25

-6        -6

x=19

The goal of this problem was to find the product of x and y so now we have to multiply them

19*6=114

Your answer is 114

Plot two points to represent the temperatures -0.9°F and -1.2° on the number line

Answers

Red = -1.2°

Blue = -0.9 °

Answer Below:

The line represents the range of temperatures, and the points (-0.9°F and -1.2°F) are marked at their appropriate positions on the number line.

 -1.2°F         -0.9°F

   |------------------|------------------|

A number line represents a range of numbers in order.

The numbers increase as we move to the right and decrease as we move to the left.

Now, we have to plot -0.9°F and -1.2°F on a number line:

-0.9°F:

Start at the origin (usually marked with 0), move slightly to the left, and place a point there.

This point represents -0.9°F.

-1.2°F:

Start at the same origin, move further to the left, and place another point there.

This point represents -1.2°F.

So, on the number line, we would have something like this:

 -1.2°F         -0.9°F

   |------------------|------------------|

The line represents the range of temperatures, and the points (-0.9°F and -1.2°F) are marked at their appropriate positions on the number line.

Answers

Answer:

2x+13=1, Given.

2x+1=3, multiplied both sides by 3.

2x=2, subtracted 1 from both sides.

x=1, divided both sides by 2.

NOTE: Your school may use special names for all of those proofs. If so, I don't know what they are. Sorry.

Step-by-step explanation:

For the first non-given statement, everything is over 3. A simple law of fractions is that the top number/s is being divided by the bottom, so all we need to do to reverse it is multiply it all by 3. This includes the other side.

For the second, it begins to get much easier as we've past the hardest step. Subtracting 1 from both sides gets us 2x = 2.

For the third, it is again easier. All that's left is to divide by 2 because that's what x is being multiplied by. After we do that, x turns out to be 1.

If an airplane traveled 414 miles how fast did it travel in 3/4 of an hour?

Answers

Answer:

The issue needs you to calculate Claire's airplane's speed in miles per hour.

Claire's airplane travels at a speed of 552 miles per hour.

Given:

414 miles total distance traveled

Time allotted = 3/4 hour

Total distance traveled / Total time = Speed

= 414 miles per hour

414 4/3 = 414

= (414 4 / 3)

1656 / 3 =

equals 552 miles per hour

As a result, Claire's airplane's speed in miles per hour is 552 miles per hour.

The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of JK : KL : LM is equal to 2:1:2. If JM=30, find JL.

Answers

JKLM forms a line segment.  In this, the ratio of JK : KL : LM is equal to 2:1:2.  We know that JM = 30 cm.

JK = 2x

KL = x

LM = 2x

JM = JKLM = 30 cm

JL (JK + KL) = 2x + x = 3x

So,

JL + LM = JKLM

3x + 2x = 30

5x = 30

x = 30/5

x = 6.

JL = 3x = 3 × 6 = 18 cm.

=》 JL = 18 cm.
