Solve. The subject is Quadratic Equations, and you have to solve by factoring. I have already identified that x can equal 6, but cannot equal 3/2
Answer:
x1=3/2 x2=6
Step-by-step explanation:
4x²+18x-36=0
2(2x²+9x-18)=0
81-4*2*(-18)=225
x1=(-9+15)/4=3/2
x2=(-9-15)/4=6

Avocados Price
1 $1.15
2 $2.30
5 $5.75
10 $11.50
How much will 4 avocados cost?
A. $1.15
B. $4.60
C. $3.45
D. $4.45
Step-by-step explanation:
You can choose one of the prices above to find the proportion.
[tex] \frac{2}{4} = \frac{2.30}{y} \\ 2 \times y = 2.30 \times 4 \\ y = 2.30 \times 2 \\ y = 4.60[/tex]

Step-by-step explanation:
All numbers belong to the set of numbers known as the real number system. The real number system consists of
every number you have ever dealt with since you were old enough to count. The numbers in the real number system
are divided into two main groups. One group is called the rational numbers and the other is called the irrational
numbers. The set of irrational numbers consists of all numbers that are not rational. This set of irrational numbers
includes those numbers that cannot be written as the ratio of two integers, non-remediate numbers.
and decimals that do not have a repeating pattern of digits. For example, pi(π),
√
2,−2.345876921... are irrational
numbers.
The set of rational numbers includes natural numbers, whole numbers, integers, numbers that can be expressed as
the ratio of two integers, a decimal number that terminates, and decimal numbers that have a repeating pattern of digits.
The natural numbers are the set of positive integers. For example, 1, 2, 3. . . are all natural numbers. The whole
numbers are the natural numbers and zero. For example, 0, 1, 2, 3. . . are all whole numbers. The integers are
the whole numbers and their opposites. For example, -2, -1, 0, 1, 2. . . are all integers. A rational number is any
number that can be expressed in the form of a
b where b 6= 0. When a rational number is expressed as a decimal, it
decimal will terminate (end) or For example, 1
2
,
√
81,−7.456 545 654 are
all rational numbers.
When you classify numbers remember that they can often belong to more than one set of numbers. If you think of
the number 3, you can call it a natural number, a whole number, an integer and a rational number.
The following table may help you to better understand the real number system.

Alison works at the mall and makes a commission of 10% on each clothing sale. If she sold $925 in clothing yesterday, how much commission did she earn?
Answer:
92.50$
Step-by-step explanation:
Answer:
$92.50
Step-by-step explanation:
$925 * 10%= $92.50
She earned $925, and she gets a 10% commission, so you would do the problem 10% of $925, which is $925 * 10%, which equals $92.50.
Apple and cranberry juice are mixed in a ratio of 5 to 3. What amount of each juice would be needed to make a 64-fluid ounce pitcher of apple-cranberry juice?
Answer:
32
Step-by-step explanation:
64/2=32
Answer:
[tex]\text{Apple juice needed: }40\:\mathrm{oz},\\\text{Cranberry juice needed: }24\:\mathrm{oz}[/tex]
Step-by-step explanation:
Let [tex]a[/tex] be the amount of apple juice needed, in ounces. Let [tex]c[/tex] be the amount of cranberry juice needed, in ounces. We can set up the following system of equations:
[tex]\begin{cases}a=\frac{5}{3}c, \\a+c=64\end{cases}[/tex]
Solving, we get:
[tex]\frac{5}{3}c+c=64,\\\\\frac{8}{3}c=64,\\\\c=\frac{64\cdot 3}{8}=\boxed{24\:\mathrm{oz}}[/tex]
[tex]a=\frac{5}{3}c,\\\\a=\frac{5}{3}(24),\\\\a=\boxed{40\:\mathrm{oz}}[/tex]

Answer: 12?????? i dont know what the question is saying bc ur took a picture of something too close maybe get the whole question?
Step-by-step explanation:
Part A
y varies directly with x, so we know that y = kx for some constant k. Why the letter 'c' isn't used as a constant, instead of k, I'm not entirely sure.
We're told that x = 0.5 and y = 36. Let's use those values to find k
y = kx
36 = k*0.5
36/0.5 = k
72 = k
k = 72
The equation y = kx updates to y = 72x
As a check, plug x = 0.5 in to get,
y = 72x
y = 72*0.5
y = 36
which helps show that we have the correct equation.
Answer: y = 72x===============================================================
Part B
If y = 1/3, then,
y = 72x
1/3 = 72x
72x = 1/3
x = (1/3)*(1/72)
x = (1*1)/(3*72)
x = 1/216
Note how I multiplied both sides by 1/72, which is the same as dividing both sides by 72.
Answer: x = 1/216Solve 7/4x + 5/6=4/3x - 3 for x
Answer:
x=-46/5
Step-by-step explanation:
1. subtract either 5/6 or add 3 for each side.
2. combine terms
3. x=-46/5

How do you multiply a fraction by a whole number?
Multiply the top number of the fraction by the whole number and then place that over the lower number of the fraction. Then you can see if the new fraction can be reduced or rewritten as a proper fraction.
Example:
1/2 x 3 would be (1 x3) / 2 = 3/2 which can be rewritten as 1 1/2
Example: [tex]\frac{2}{5}*10=\frac{2}{5}*\frac{10}{1}=\frac{20}{5}=4[/tex]

Jason has sport cards in his pocket. He has three football cards, one wrestling card and two baseball cards. If Jason reaches into his pocket and selects one card, what is the probability he will get a baseball card? Show your answer in lowest terms.
Answer:
In lowest terms, there is a 1/3 probability of Jason pulling out a baseball card.
Step-by-step explanation:
There are a total of 6 cards. 4/6 of them are football and wrestling which results in 2 baseball cards. So the probability is 2/6 but since the question wants it in lowest terms, you would have to simplfy 2/6. Divide the top by 2 and the bottom by 2 which gets you 1/3.
