What are the lengths of side AB and side BC?
Answer: AB=20, BC=14
Step-by-step explanation:
set AB together with the side congruent to it (which is DC)
3x-7=x+11
subtract x and add 7 to both sides
2x=18
divide both sides by 2
x=9
plug 9 in for AB.
3(9)-7
27-7=20.
now do the same for BC
Answer:
AB = 20
BC = 14
Step-by-step explanation:
ABCD is a parallelogram
Opposite sides of a parallelogram are equal.
Therefore,
AB = DC
3x - 7 = x + 11
3x - x = 11 + 7
2x = 18
x = 18/2
x = 9
AB = 3x - 7 =3*9 - 7 = 27 - 7 = 20
7y - 7 = 3y + 5
7y - 3y = 7 + 5
4y = 12
y = 12/4
y = 3
BC = 7y - 7 = 7*3 - 7= 21 - 7 = 14

tom rides the bus part of the way to school and then he walks the rest pf the way. he walks five minutes longer than he rides. the whole trip takes 27 minutes. for how many minutes does he walk
Answer:
16 minutes
Step-by-step explanation:
Tom walks for 5 minutes longer than he rides. To figure out the answer, start by subtracting 5:
27 - 5 = 22
Now that you have done this, divide 22 by 2:
22/2 = 11
Now you know that he rode the bus for 11 minutes, and you can add five to the other 11 minutes to know how long he walked:
11 + 5 = 16.
Answer:
Tom walked 16 minutes.
Step-by-step explanation:
If the walk is five minutes longer than the bus ride, we just need to subtract the five minutes, and divide the rest by two. (b) will be the time of the bus ride.
[tex]27=2b+5\\27-5=2b\\22=2b\\22/2=b\\11=b[/tex]
The bus ride would be 11 minutes long, we just add five minutes to that for the time of the walk. (w) will be how long the walk took.
[tex]11+5=w\\16=w[/tex]

what’s the length of E to D
what’s the length of B to E
Given:
In triangle ACD, BE||CD, AB = 20 cm, BC = 5 cm, CD = 18 cm, AE = 26 cm.
To find:
(a) The length of ED.
(b) The length of BE.
Solution:
In triangle ABE and ACD,
BE||CD, so angle ABE and angles ACD are corresponding angles. So, their measure are equal.
[tex]m\angle ABE=m\angle ACD[/tex] (Corresponding angles)
[tex]m\angle BAE=m\angle CAD[/tex] (Common angle)
Now,
[tex]\Delta ABE\sim \Delta ACD[/tex]
Corresponding sides of similar triangles are proportional.
[tex]\dfrac{AB}{AC}=\dfrac{BE}{CD}=\dfrac{AE}{AD}[/tex]
(a)
[tex]\dfrac{AB}{AC}=\dfrac{AE}{AD}[/tex]
[tex]\dfrac{20}{20+5}=\dfrac{26}{AD}[/tex]
[tex]\dfrac{20}{25}=\dfrac{26}{AD}[/tex]
[tex]0.8=\dfrac{26}{AD}[/tex]
Isolate AD.
[tex]0.8AD=26[/tex]
[tex]AD=\dfrac{26}{0.8}[/tex]
[tex]AD=32.5[/tex]
Now,
[tex]AD=AE+ED[/tex]
[tex]32.5=26+ED[/tex]
[tex]32.5-26=ED[/tex]
[tex]6.5=ED[/tex]
Therefore, the length of ED is 6.5.
(b)
[tex]\dfrac{AB}{AC}=\dfrac{BE}{CD}[/tex]
[tex]\dfrac{20}{25}=\dfrac{BE}{18}[/tex]
[tex]0.8=\dfrac{BE}{18}[/tex]
Multiply both sides by 18.
[tex]14.4=BE[/tex]
Therefore, the length of BE is 14.4.
Which statements about the diagram are correct? Check all that apply.
BD = 9 in.
AB = 36 in.
DC = 6 StartRoot 3 EndRoot in.
AC = 12 StartRoot 3 EndRoot in.
BC = 18 StartRoot 3 EndRoot in.
Answer:
(C)DC = 6 StartRoot 3 EndRoot in.
(D)AC = 12 StartRoot 3 EndRoot in.

A linear function includes the points (2, 3) and (6, 8). What is the rate of change of the linear function?
Write the answer as an improper fraction (fraction greater than one) in lowest terms.
Answer:
The rate of change of a linear function = 5/4
Step-by-step explanation:
Given that a linear function includes the points (2, 3) and (6, 8).
So we have the points
(2, 3)(6, 8)We know that the rate of change of a function is also termed as the slope of the function.
In other words, the slope of the linear function gives us the rate of change of the linear function.
Thus,
Determining the rate of change or slope between (2, 3) and (6, 8)
(x₁, y₁) = (2, 3) (x₂, y₂) = (6, 8)Using the formula
Rate of change = Slope = [y₂ - y₁] / [x₂ - x₁]
= [8 - 3 / [6 - 2]
= 5 / 4
Thus, the rate of change of a linear function = 5/4

Express this number in scientific notation.
31 billion
Answer:
3.1 * 10^10
Step-by-step explanation:
we know 1 billion is 1,000,000,000
In scientific notation
1,000,000,000=1 * 10^9
To find the value of 31 Billion
Multiply the value of one billion for 31
so
31 * 1 * 10^9 = 31 * 10^9
= 3.1 * 10^10
Is the following relation a function?
Y = 3x
Answer:
Yes
Step-by-step explanation:
If you subsitute for x, x will only repeat if it has the same y value.
Yes, The given relation is a function.
Here,
The relation is given as; Y = 3x
We have to find the given relation is a function or not.
What is Function?
A relation is said to be function if there is exactly one value for each value of y.
Now,
The given relation is,
Y = 3x
When, we put x = 1 then y = 3
And, when x = 2 then y = 6 and so on.
Clearly, there is exactly one value of x for value of y.
So, The given relation is a function.

Write the equation of the line in slope-intercept form that passes through
the point (-3, 5) and is parallel to y = -2/3 x
Answer:
y= -2/3x+3
Step-by-step explanation:
Parallel lines have the same slope but different y-intercepts.
y=-2/3x is your original equation
Your slope is still -2/3
y=mx+b
y=-2/3x + b
Substitute the points from the coordinates
5 = -2/3(-3) + b
5 = 2 + b
-2 -2
b=3
Your parallel line equation is: y= -2/3x+3

On a number line point x is located at 2 / 3 on a second number line point y is the same distance from zero as point x what has a numerator of 8 what is the in denominator of y
Answer:
12
Step-by-step explanation:
Given that :
Point X on number line 1 from 0= 2/3
Point Y on number line 2 from 0 = same distance as point X on number line
Point Y has a denominator of 8 ; the numerator is thus;°
Let denominator = d ; Fraction becomes 8/d
Thus `
Point X on 1 = point Y
2/3 = 8/ d
2d = 3 * 8
2d = 24
d = 12
