Adam has 3 coins in his pocket and they are all different from each other. Ben has 3 coins in his pocket and they are all the same as each other. Adam has half as much money as Ben.
What are the coins they each have?
Answers
Answer:
The possible coins are:
P = penny = $0.01
N = nickel = $0.05
D = dime = $0.10
Q = quarter = $0.25
H = half dollar = $0.50
We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)
Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X
We know that Adam has half as much money as Ben, this can be written as:
(A + B + C) = 3*X/2
The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.
For example, if X = $0.10
then:
(A + B + C) = $0.10*(3/2) = $0.15
We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.
if x = $0.50 then:
(A + B + C) = (3/2)*$0.50 = $0.75
Here we could have:
A = $0.50
B = $0.25
then: A + B = $0.75
But we still have the coin C.
If we take X = $0.25 then:
(A + B + C) = (3/2)*$0.25 = $0.375
We could round the right part to $0.40
then the coins in the left part would be:
A = $0.25
B = $0.10
C = $0.05
A + B + C = $0.25 + $0.10 + $0.05 = $0.40

A circle has a radius of 7.6 cm.
Work out the area of the circle.
Give your answer correct to 3 significant figures.
Answers
Answer:
181cm²
Step-by-step explanation:
Given
Radius of a circle = 7.6cm
Area of the circle = \pi r²
Substitute
Area of the circle = 3.14(7.6)²
Area of the circle = 3.14(57.76)
Area of the circle = 181.3664cm²
Area of the circle to 3sf is 181cm²

(a) Work out the value of I when x = 5 and y=-7
Answers
Note: Consider the dependent variable is T instead of I, and we need to find the value of T when x=5 and y=-7.
Given:
[tex]T=3x+4y[/tex]
To find:
The value of T when x=5 and y=-7.
Solution:
We have,
[tex]T=3x+4y[/tex]
Putting x=5 and y=-7, we get
[tex]T=3(5)+4(-7)[/tex]
[tex]T=15-28[/tex]
[tex]T=-13[/tex]
Therefore, the value of T is -13 when x=5 and y=-7.

Answers
Answer:
x=2
Step-by-step explanation:
3x+3+10x-25-2x+4=4
11x-18=4
11x=4+18
11x=22
x=22/11
x=2
Answer:
x = 2
Step-by-step explanation:
3(x + 1) + 5(2x –5)–2(x –2)= 4
First, let's distribute the numbers across the parentheses through multiplication.
3x + 3 + 10x - 25 - 2x + 4 = 4
Combine like terms.
11x - 18 = 4
Add 18 to both sides to isolate x.
11x = 22
Divide both sides by 11 to isolate x further.
x = 2
Check by plugging 2 back into the equation.
3(2 + 1) + 5(2(2) - 5) - 2(2 - 2) = 4
3(3) + 5(4 - 5) - 2(0) = 4
9 + 5(-1) - 0 = 4
9 - 5 = 4
4 = 4
Your answer is correct.
Hope this helps!

Use the GCF and the distributive property to find the sum of 22+33
Answers
Answer:
22 + 33 = 55 the GCF of 22 and 33 is 11
Step-by-step explanation:
The sum of 22 and 33 by using distributive property will be; 55.
How to find Greatest common factor?The greatest common factor, as the name implies, is the greatest among all common factors among the quantities given.
We can factorize the quantities in the smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could.
Factors:
22: 1 ,2, 11, 22
33: 1, 3, 11, 33
Both the numbers have a GCF of 11. Then by removing 11 from both numbers you end up with:
22 = 2 x 11
33 = 3 x 11
Now replace the values on the right of the equals sign into the original equation then;
(2 x 11) + ( 3 x 11)
The distributive property allows us to remove the common values and rewrite them;
11(2 + 3)
11(5)
55
The sum of 22 and 33 by using distributive property will be; 55.

A newspaper article reports the results of an election between two candidates. The article says that Smith received 60% of the votes and that Murphy received 15 of the votes. A reader writes in to complain that the article cannot be accurate. What reason might the reader have to say this?
Answers
Step-by-step explanation:
Since, smith receives 60% of the vote this means murphy must receive 40% of the vote. Therefore 15 = 40% of the total vote.
Thus total vote = 37.5, which is kind of absurd. As total vote count must be an integer. Moreover, the report must be consistent with the result, which does not seem in this case.
Solve using the substitution method. 3x +2y= 19 xy= 15
Answers
Answer:
when x = 3 1/3, y = 4.5
or
when x =3 , y = 5
Step-by-step explanation:
Here, we want to solve using substitution
xy = 15
let x = 15/y
Put this into the first equation;
3(15/y) + 2y = 19
45/y + 2y = 19
Multiply through by y
45 + 2y^2 = 19y
2y^2 -19y + 45 = 0
2y^2 - 10y - 9y + 45 = 0
2y(y-5) -9(y-5) = 0
(2y-9)(y-5) = 0
2y-9 = 0
or y-5 = 0
2y = 9 or y = 5
y = 9/2 or y = 5
y = 4.5 or y = 5
Recall;
x = 15/y
x = 15/4.5 or x = 15/5
x = 3 1/3 or x = 3
