You buy 4 balloons and 2 banners for $8. Your friend buys 6 balloons and 1 banner for $8.
Each balloon costs ?$
and each banner costs ?$
Answer:
Each balloon costs $1
Each banner costs $2
Step-by-step explanation:
First of all, let's write down the equation from this problem.
Let "y" be the cost of the ballon, and let "x" be the cost of a banner. Then the following is true from the question...
4y + 2x = 8
6y + x = 8
Now since both of them are equal to 8 both of them are equal to each other, and so we can get the following equation...
4y + 2x = 6y + x
2x - x = 6y - 4y
x = 2y
Now if we substitute 2y instead of x in one of the previous equations we will obtain...
6y + x = 8
6y + 2y = 8
8y = 8
y = 1
From the equation x = 2y we know that...
x = 2y
x = 2(1)
x = 2

Given the function g(x) = -3x + 4, compare and contrast g(-2) and g(4). Choose the statement that is true concerning these two values.
Answer: D
Step-by-step explanation:
Fill in the x's with -2 for the first time to get one answer then go back and fill in 4 for the second answer.
g(-2)= 10
g(4)=-8
Proving g(-2) is greater than g(4).

this year Benny is 12 years old and his mom is 48 years old what percent of his mom's age is Benny's age
Answer:
25%
Step-by-step explanation:
Let's set up a percent proportion:
12/x = 48/100
To solve for x, we would do:
x = (12*100)/48 = 1200/48 = 25
x = 25%
In my opinion, the easiest way to do this would be to look at this and notice that 12 * 4 =48 so that means 12 is 1/4 of 48 and 1/4 = 25%.

30. A mom bought her kids 3 cartons of milk
for $1.25 each and 6 doughnuts. The total
cost was $6.90. Write an equation to
determine the cost of a doughnut.
Answer:
x = (1.25 * 3 - 6.90) divided by 6
Step-by-step explanation:
this will get the price of all the milk, then take it out of the total price, then divide it by 6 because there are 6 donuts, this will give you the price of 1 donut
Answer:
$3.15
Step-by-step explanation:
$1.25x3=$3.75
$6.90-$3.75=$3.15

PLS HELP WILL MARK BRAINLIEST
Answer:
To factor out the following expression you would you would need to remove the (a + 1) term out of the expression, which leads to :
(a+1) (b(a+1) - 5
Step-by-step explanation:
This is the final expression

:
4a2 - b2
Simplify ————————
2a - b
Trying to factor as a Difference of Squares:
2.1 Factoring: 4a2 - b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (2a + b) • (2a - b)
Canceling Out :
2.2 Cancel out (2a - b) which appears on both sides of the fraction line.
Final result :
2a + b

A group of students are going on a trip and the trip costs $36.50 per student which includes $9.50 for lunch, an entrance ticket and a gift coupon. The gift coupon costs $50 for the entrance ticket. The cost of an entrance ticket is
A) $27.00
B) $25.00
C) $18.00
D) $13.50
Answer:
The answer is D) $13.50

So first what you're gonna do it subtract $9.50 from $36.50 which will get you to $27.00.
Then you'll have to figure out what half of $27.00 is.
That will get you to the answer of D) $13.50

If the length of the legs of a right triangle are 5 m and 7 m, what is the length of the hypotenuse?
Answer:
[tex]c = 8.60232526704263[/tex]
[tex]c \approx8.6[/tex]
Step-by-step explanation:
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex]c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
[tex]c = \sqrt{ {5}^{2} + {7}^{2} } [/tex]
[tex]c = \sqrt{25 + 49} [/tex]
[tex]c = \sqrt{74} [/tex]

You are taking a quiz that has 9 multiple-choice questions. If each question has 3 possible answers, how many different ways are there to answer the test?
Answer:
19 683
Step-by-step explanation:
Think of it as s lock..
A normal combination lock usually have 3 scrollwheels with 10 different positions in them.. (0 1 2 3 4 5 6 7 8 9)
The smallest number you can make is 000
and the biggest is 999
therefore there are a total number of 1000 possible combinations. (001, 002, 003 ... 134, 135, 136 ... 876, 877)
I think you get it.
Simply: 10 ^ 3 = 1000
In your question we have 9 "scroll wheels" with 3 "different positions" in them
So we simply do: 3 ^ 9 = 19 683
