Answer:
Solution :
{x,y} = {0/14261512,4}
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 4
// Plug this in for variable y in equation [1]
[1] 12x - 5•(x +4) = -20
[1] 7x = 0
// Solve equation [1] for the variable x
[1] 7x = 0
[1] x = 0
// By now we know this much :
x = 0
y = x+4
// Use the x value to solve for y
y = (-0/14261512)+4 = 4

Answer:
135 in degree measure.
Step-by-step explanation:
the angle opposite to 35 becomes also 35 by the rule vertically opposite angle. Then The traingle has three points as 100 and 35. Similarly the remaining angle becomes 45 .then 45+ unknown angle is equal to 180 by linear pair law. hence it becomes 135.....

In one basketball game, Zaid made 7 two-point and three-point baskets to score 17 points. Let x represent the number of two-point baskets, and y represent the number of three-point baskets. This situation can be represented by the system x+y=7 and 2x+3y=17 . How many of each type of basket did Zaid make?
Answer:
y =three point score = 3
x = two point score = 4
Step-by-step explanation:
this question can be solved using simultaneous equation
x + y = 7 eqn 1
2x + 3y = 17 eqn 2
Multiply eqn 1 by 2 to derive eqn 3
2x + 2y = 14 eqn 3
Subtract eqn 3 from 2 :
y = 3
Substitute for y in eqn 1
x + 3 = 7
x = 4
You pick a card at random. Without putting the first card back, you pick a second card at random.What is the probability of picking a 7 and then picking a number less than 5?
Simplify your answer and write it as a fraction or whole number.
Answer:
[tex]Probability\ of\ picking\ a\ 7=\frac{1}{10}\\Probability\ of\ picking\ a\ card\ less\ than\ 5=\frac{4}{9}[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\The\ total\ outcomes\ to\ the\ Random\ Experiment\ A\ are\ 1,2,3,4,5,6,7,8,9,10.\\ (We\ don't\ consider\ Ace\ Cards\ or\ Face\ Cards, here.)\\Hence,\\Lets\ consider\ picking\ the\ first\ Card:\\\\Here,\\The\ favorable\ condition\ is\ getting\ a\ 7.\\ No.\ of\ favorable\ elementary\ events=1\\ Total\ no.\ of\ elementary\ events=10\\ We\ know\ that,\\[/tex]
[tex]Probability[of\ an\ Event\ A]=\frac{Favourable\ no.\ of\ elementary\ events\ to\ A}{Total\ no.\ of\ elementary\ events}\\Probability[of\ picking\ a\ 7]=\frac{1}{10}[/tex]
[tex]Now,\\As\ we've\ already\ picked\ a\ card[i.e\ 7],\\The\ total\ outcomes\ to\ the\ Random\ Experiment\ A\ are\ 1,2,3,4,5,6,8,9,10.\\Hence,\\Lets\ consider\ picking\ another\ card\ less\ than\ 5:\\Here,\\The\ favorable\ condition\ is\ picking\ a\ card\ less\ than\ 5.\\Hence,\\The\ favorable\ outcomes\ are\ 1,2,3,4.\\No.\ of\ favorable\ elementary\ events=4\\Total\ no.\ of\ elementary\ events=9\\As\ we\ already\ know\ that,\\[/tex]
[tex]Probability[of\ an\ Event\ A]=\frac{Favourable\ no.\ of\ elementary\ events\ to\ A}{Total\ no.\ of\ elementary\ events}\\Probability[of\ picking\ a\ card\ less\ than\ 5]=\frac{4}{9}[/tex]

If there are 180 students in the girls athletics program, then
how many students participated in soccer?
Answer:
27
Step-by-step explanation:
15: 100 = x : 180
x = (180 x 15) / 100 = 27
Answer:
27
Step-by-step explanation:
Seems like your question(shown/written) is incomplete. Based on the given data.
15% of the total students participated in soccer
15% of 180 students participated in soccer
=> 15/100 x 180
=> 2700/100
=> 27
27 students participated in soccer

The value of Desmond's home is modeled by the function V (x) = 275,000(1.09) ²/³x, where x is the number of years since 2012. By what approximate percentage rate is the value of Desmond's home increasing per year?
Answer:
6%Step-by-step explanation:
Given function
V(x) = 275000(1.09)^(2/3x)Every year the value is changing at the rate:
(1.09)^(2/3) = 1.059 ≈ 1.06The rate of 1.06 is equivalent of 6% increase per year
Jane had $d to buy three beanie babies.(in our problem they all cost the same). If she were to buy all three, she'd spend all her money. Instead, she bought just one. How much money dose Jane have left
Answer:
$4
Step-by-step explanation:
If she have $6 so 6-2=4
If buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b[/tex]= a divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )
Given that:
Total money Jane had = $d3 beanie babies are of same costTheir whole cost is $d (as buying them all makes Jane spend all her money).To find:
The amount she'd save if she buy only one such beanie baby.
Amount that she'd save = Total amount she could've spent - Total price of one beanie baby
As we know, total amount she could've spent = $d
Also, because of 3 beanie babies cosing equal, and total cost being $d,
the cost of each beanie baby is:
$d divided in 3 equal parts = d/3 dollars
Thus, we get:
Amount that she'd save = Total amount she could've spent - Total price of one beanie baby
Amount that she'd save = [tex]d - \dfrac{d}{3} \: \rm dollars[/tex]
We can write d = 3d/3 since dividing and multiplying a number by same non-zero number doesn't affect that number.
We do so, so that that both terms could get in fraction form with same denominator so that numerators could work directly.
[tex]d - \dfrac{d}{3} = \dfrac{3d}{3} - \dfrac{d}{3} = \dfrac{3d - d}{3} = \dfrac{2d}{3}[/tex]
Thus, if buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

-Lil G
Answer:
x=25
Step-by-step explanation:
Hey There!
Those angles are supplements meaning all of them added together will equal 180
so we set up an equation
180 = 3x+2x+80 and solve for x
step 1 combine like terms
3x+2x=5x
now we have
180=5x+80
step 2 subtract 80 from each side
180-80=100
80-80 cancels out
now we have
5x=100
step 3
divide each side by 5
5/5 cancels out
100/5=25
x=25
Therefore the value of x is 25

Margaret and Kevin both have to write an expression that is equivalent to 6 to the power of -4. Part A Who is correct? Part B What is a possible error made by the incorrect student?
Margaret writes 6 x (1/6 to the power of 5)
Kevin writes 1/6 x (6 to the power of 4)
Please help
Answer:
Margret is correct, Kevin is wrong.
Step-by-step explanation:
6^-4 can be written as (1/6)^4
By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4
Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.
