Answer:
4y and 3y
Step-by-step explanation:
4y and 3y are like terms because they have y after the number. Every time when a math problem ask you to combine like terms, it'll be the ones that have the same variables or powers.
What is the value of c in the equation x^15/x^c =x^6
Step-by-step explanation:

1. A green light blinks every 4 seconds and a yellow light blinks every 5 seconds. When will both lights blink at the same time?
:
2. A red light blinks every 12 seconds and a blue light blinks every 9 seconds. When will both lights blink at the same time?
:
3. Explain how to determine when 2 lights blink together.
:
Answer:
1) both lights will blink at the same time every 20 seconds
2)Both lights will blink at the same time every 36 seconds
3) How to determine when 2 lights will blink together is that you must find the least common factor (LCM) of both numbers and when both hit the same number then that is when both lights blink at the same time.
Step-by-step explanation:
For example for number 1 we have 4 and 5 seconds when the lights blink
4: 4, 8, 12, 16, 20...
5: 5, 10, 15, 20...
we see that the LCM factor is 20 and that is when both lights will hit at the same time.

Answer:
x = 9
Step-by-step explanation:
Perimeter of rectangle = 2(l+b) = 42
=> 2(x+3 + x)
=> 2 (2x + 3) = 42
=> 4x + 6 = 42
=> 4x = 42 - 6
=> 4x = 36
=> x = 36/4
=> x = 9
Hope it helps :)
Answer:
Formula = (l + b) x 2= 42 so answer = x=9
Step-by-step explanation:
l =x
b =x+3
( x+x+3) * 2 =42
2x +3 x 2 = 42
2x +3 = 42/2
2x +3 = 21
2x = 21 - 3 =18
x = 18/2
x=9

What is the y=mx+b of the equation 3x−2y=12
Answer:
y=3/2x-6
Step-by-step explanation:
To find the y=mx+b you need to move the y on one side while moving the others on the other side
First, move the 3x to the other side by subtracting by 3x on both sides:
-2y=-3x+12
Divide by -2 on both sides:
y=3/2x-6
Answer:
y=3/2x-6
Step-by-step explanation:
3x-2y=12
isolate the y:
-2y=-3x+12
get rid of the coefficient in front of y by dividing by -2
y=-3/-2x+12/-2
y=3/2x-6

18 people need to buy tickets in order to get the group rate.Which inequality shows the number of people ,p, that need to buy tickets in order to get the group rate?
Answer:
[tex]p \ge 18[/tex]
Step-by-step explanation:
The question has missing details. See comment for missing information
Given
[tex]People = 18[/tex] -- at least
Required
Represent as an inequality
In inequalities:
At least means [tex]\ge[/tex] i.e. greater than or equal to
From the question, the number of people is represented with p.
So, at least 18 people is represented as:

Trapezium ABCE is made from parallelogram ABCD
and isosceles triangle ADE.
A
B
106°
E
D
Work out the size of angle AED.
Answer:
Angle AED=32 degrees
Step-by-step explanation:
angle ADC=angle ABC because parallelogram
then angle ADC=106 degrees
angle EDA is supplementary to angle ADC (ADC+EDA=180 degrees)
then angle EDA=74 degrees
because triangle ADE is isosceles, angle EAD=angle EDA
since the total angles in a triangle =180 degrees,
Angle AED=180-2(74)=32 degrees
Applying the definition of isosceles triangle and parallelogram, the size of angle AED is: 32°.
Facts about Parallelogram and Isosceles TriangleThe opposite angles in a parallelogram have equal angle measures.The two angles that are directly opposite the two equal sides in an isosceles triangle are congruent.Thus:
m∠ABC = m∠ADC = 106° (opposite sides of parallelogram)
m∠ADC = 106°
m∠ADE = 180 - 106 = 74°
m∠AED = 180 - 2(74) (isosceles triangle)
m∠AED = 32°
Thus, applying the definition of isosceles triangle and parallelogram, the size of angle AED is: 32°.

Here,
The graphs show their distances from home over the same 30-minute period as they walked to the park.
From the graph,
It can be concluded that,
Both reach the park at the same time, as the termination point of the curve is the same.
The graph of mia starts after 10 minutes Erick, which implies Mia left her house 10 minutes before Erick left his house. And Erick walked the same distances as Mia during the last 10 minutes as the slope of the last segment of both curves is the same.
