Step-by-step explanation:
∠A and ∠B are vertical => ∠A=∠B
20x+10=30x-10
20x-30x= -10-10
-10x= -20
x= -20 / -10 = 20 / 10 = 2
x=2
Good luck!
Answer:
2
Step-by-step explanation:
Ok remember this because its going to appear alot in geometry. Vertical angles are ALWAYS congruent and congruent means when two things are equal/ are the same.
If angle a and b are vertical angles what does that mean?
they are CONGRUENT!
you know A = 20x+ 10 and B= 30x-10
so you can write it as
20x+10 = 30x-10
because Angle A and B equal each other
then get the variable by itself so subtract -20x on both sides
10 = 10x-10
then add 10 to both sides which is
20 = 10x
and divide 10 on both side and 20 divided by 10 is 2
so 2 =x
which is the same as x =2
Billy is paid $100 for 25 hours of work. What is the rate?

Eliza's backpack weighs 18 and StartFraction 7 over 9 EndFraction pounds with her math book in it. Without her math book, her backpack weighs 14 and StartFraction 7 over 8 EndFraction pounds. How much does Eliza's math book weigh? 3 and StartFraction 11 over 72 EndFraction pounds 3 and StartFraction 65 over 72 EndFraction pounds 4 and StartFraction 11 over 72 EndFraction pounds 4 and StartFraction 65 over 72 EndFraction pounds
Answer:
[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]
Step-by-step explanation:
Given
[tex]Backpack = 18\frac{7}{9}kg[/tex] --- with math book
[tex]Backpack = 14\frac{7}{8}kg[/tex] --- without math book
Required
Determine the weight of her math book
To do this, we simply calculate the difference in the weights given.
Math Book= Backpack(with math book) - Backpack (without math book)
[tex]Math\ Book = 18\frac{7}{9} - 14\frac{7}{8}[/tex]
[tex]Math\ Book = \frac{169}{9} - \frac{119}{8}[/tex]
Take LCM
[tex]Math\ Book = \frac{8 * 169 - 9 * 119}{72}[/tex]
[tex]Math\ Book = \frac{1352 - 1071}{72}[/tex]
[tex]Math\ Book = \frac{281}{72}[/tex]
[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]

One factor of a polynomial p(x) is (x + 7).
What is the numerical value of p(-7)?
Dene-
My Progress
The required value of function p(x) at x = -7, p(-7) is zero.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
As given that one factor of a polynomial p(x) is (x + 7).,
Since factor x, + 7 also represents one of the zeros of a polynomial function p(x).
So, when one put the value x = -7 in the function, the function gives zero in the outcome.
Thus, the required value of function p(x) at x = -7, p(-7) is zero.

3 =2b -3 can someone help me understand this
Answer:
Step-by-step explanation:
Answer: 3=b
Step-by-step explanation:
First get the like terms 3 and (-3) on one side.
You do this by either adding or subracting, it depends on the sign of the number. -3 is negative 3 but you have to add it to make it zero and on the other side you add it and get 6.
Then you divide 6 by 2. 2b by 2 to get the variable alone and 3=b is your answer.

A phone company has two long distance plans. Plan A charges a flat monthly fee of $13 and $0.37 per minute of long distance calls Plan B charges a flat monthly fee of $28 and $0.15 per minute of long distance calls. After how much time on long distance calls to the nearest minute, would the cost of plan A be equal to the cost of plan B?
Answer:
68.18minStep-by-step explanation:
let the cost of plan A be Y1
and the cost of plan B be Y2
let the number of minutes for both plans be x
let us model the cost of plan A
Y1= 13+0.37x-------1
let us model the cost of plan B
Y2= 28+0.15x------2
when Y1=Y2, we can now solve for x which is in minutes
13+0.37x=28+0.15x
collect like terms
13-28=0.15x-0.37x
-15=-0.22x
divide both sides by -0.22
x=-15/-0.22
x=68.18min
