How do you solve this using the elimination method of systems of equations?

Answers

x-2y=14      | *-1
x+3y=9

-x+2y=-14  } +
x+3y=9
---------------
   5y=-14+9
   5y=-5
   y=-5/5
     y=-1

x+ 3*(-1)=9
x-3=9
x=9+3
x=12
Since you want to eliminate in the variable, eliminate x because it can be easily crossed out. To get rid of x simply subtract the two equations. So x-x is canceled and 2y- -3y=5y and 14-9=5 so 5y=5 is 1. Now plug 1 into y and you get x=6.

On a string of red and blue lights, the red lights blink everyb3 seconds, and the blue lights blink every 5 seconds. How many times will they blink at the same time in one minute?

Answers

when will they blink together?
what is the smallest number they both mutiply to
3*5=15
so every 15 seconds
so at 15, 30, 45, 60 seconds
so 4 times if you count the time exactly at 1 minute
Final answer:

The red and blue lights will blink at the same time 4 times in one minute.

Explanation:

To determine how many times the red and blue lights will blink at the same time in one minute, we need to find the time at which both the 3-second cycle of the red light and the 5-second cycle of the blue light coincide. This is equivalent to finding the least common multiple (LCM) of 3 and 5. The LCM of 3 and 5 is 15, which means they will blink at the same time every 15 seconds.

Since there are 60 seconds in a minute, we need to find how many times 15 seconds fit into 60 seconds. 60 ÷ 15 = 4. Therefore, the red and blue lights will blink at the same time 4 times in one minute.

Answer: The red and blue lights will blink at the same time 4 times in one minute.

72 is 48% of what number

Answers

72/1 x 48/100
= 18/1 x 48/25
= 864/25
= 34 14/25

The number for which 72 is 48 percent of is approximately equal to 150.

To find the number that corresponds to 72 being 48% of it,  set up an equation.

Let "x" represent the unknown number.

The equation for "72 is 48% of x" can be written as:

72 = 0.48 × x

To solve for "x," divide both sides of the equation by 0.48:

x = 72 / 0.48

x ≈ 150

Therefore, 72 is 48 percent of approximately 150.

18 out of the 25 students are going on the field trip. What percent of the students are going on the field trip?


can you provide the math to please

Answers

Hello.
To find the percentage of how many students went on the field trip, we simply divide 18 by 25. 
18/25 = 0.72

Convert decimal into fraction.
0.72 = 72%

Thus, 18 out of 25 students = 72% of students who are going on the field trip.

You're welcome.

Can anyone explain this to me?

Answers

Yes, because of the Angle Angle Similarity Property.  Angle U in the larger triangle measures 55 degrees.  Angle X of the smaller triangle is unknown, but in the polygon formed by the smaller triangle inside the larger, X is equal to 125. Since both values of X form a straight line, they must add up to 180.  So subtract 125 from 180 and you get 55.  This would prove that at least one angle is equal, and then if you look at the top angles of the triangle, they both have Angle U, so they must also be equal.  The third choice is correct.

A lab technician is diving a cell that has a diameter of 4.32 x 10^-4 millimeters. Each of the new cells has a diameter measuring exactly one half of the diameter of the original cell . Which is the diameter of the new cell ? A. 2.16 x 5^-2 B. 2.16 x 10-2 C.2.16 x 5-4 D.2.16x 10^-4

Answers

It is very simple you will just multiply it by half
4.32 × 10^-4 /2
=2.16 × 10^-4

The answer is D.
Final answer:

The diameter of the new cell, which is exactly half the diameter of the original cell (4.32 x 10^-4 millimeters), is 2.16 x 10^-4 millimeters.

Explanation:

The lab technician is dividing a cell with an original diameter of 4.32 x 10^-4 millimeters. The new cells' diameter is stated to be exactly one half of the original diameter. Therefore, to find the diameter of the new cell, simply take half of the original cell's diameter. This can be accomplished by dividing the numerical value of the diameter by 2, which would be 4.32/2 = 2.16. The exponent remains the same because the size (magnitude) of cell diameter is only halved, not the order magnitude. So the diameter of the new cell is 2.16 x 10^-4 millimeters.

The heights of four boys measured 152.0 cm, 150.75 cm, 149.5 cm, and 149.25 cm. Bradley is the tallest, Calvin is taller than josh, but shorter than Mark. Josh is the shortest. What is Mark's height

So, Bradley is the tallest! He's 152.0 cm, then. Josh is the shortest, so he's 149.25 cm:
Bradley: 152.0 cm
???: 150.75 cm
???: 149.5 cm
Josh: 149.25 cm
Then, Calvin is taller than Josh, but he's shorter than Mark. There's only 2 spaces available left, so Calvin is 149.5 cm, and now there's only one slot left, and that means Mark is 150.75 cm.

The baker used 3 1/2 cups of pastry flour for every 1 1/2 cups of wheat flour. How many pastry flour is used per cup of west flour?

Answers

3 because there’s 3 1/2 cups for 1 1/2
Final answer:

The baker used 2 1/3 cups of pastry flour per cup of wheat flour.

Explanation:

To find out how many cups of pastry flour are used per cup of wheat flour, we can set up a proportion based on the given information:



3 1/2 cups pastry flour / 1 1/2 cups wheat flour = x cups pastry flour / 1 cup wheat flour



We can solve for x by cross-multiplying:



(3 1/2)(1) = (1 1/2)(x)



7/2 = 3/2x



Now we can solve for x by dividing both sides of the equation by 3/2:



(7/2) ÷ (3/2) = x



7 ÷ 3 = x



x = 2 1/3



Therefore, the baker used 2 1/3 cups of pastry flour per cup of wheat flour.

Find the measure of the numbered angles

Answers

Well...
Some information was cut off but I'll assume that its a parallelogram.
If it's a parallelogram, then angles 1 and 3 are equal and angle 2 and the angle marked as 110 degrees are equal.
Next we know that angles 1 and 2 are supplementary(adds to 180) so angle 1 is 70 degrees.
Because angle 3 is equal to angle 1, angle 3 is also 70 degrees.
