8x + 14y =
4 | : 2
-6x - 7y = -10
4x + 7y = 2
-6x - 7y = -10
4x - 6x = 2
- 10
- 2x = - 8
2x = 8
x = 4
8x + 14y = 4
14 y = 4 -
8x
14y = 4 - 8*4
14y = 4 - 32
14y = 28
y = 2
what is the distributive property of the GCF of 36 and 45
Jackie had $135 to spend at the mall. She spent 29% of that money on a dress. Jackie spent $___ on the dress.
So here is a better explanation
?/135 = 29%/100
100? = 135 x 29 = 3915
100?/100 = 3915/100 = 39.15
Jackie spent 39.15$
The sum of 225 can be expressed as 200 + 25. Use the Distributive Property and GCF to rewrite the sum

passes through (-1,4) and m=4
To find the equation of the line passing through the point (-1, 4) with slope 4, we use the point-slope form. Substituting the values into the formula, we find the equation to be y = 4x + 8.
Explanation:In the given question, we have a line that passes through the point (-1, 4) and has a slope of 4.
To find the equation of this line, we can use the point-slope form, which is given by y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.
Substituting the values into the formula, we get y - 4 = 4(x - (-1)). Simplifying further, we have y - 4 = 4x + 4. Rearranging the equation, we find the equation of the line to be y = 4x + 8.

Mr. Rodriguez is packing bags of snacks for his children’s lunchboxes. If he has 20 blueberries and 30 grapes, what is the maximum number of bags of snacks that he can pack so that each bag has the same number of blueberries and grapes?
With equal distribution of blueberries and grapes, Mr. Rodriguez can pack maximum of 10 bags of snacks.
What is ratio?Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Given is that Mr. Rodriguez is packing bags of snacks for his children’s lunchboxes and for that he has 20 blueberries and 30 grapes.
Now, we have -
Number of blueberries = n[b] = 20 blueberries
Number of grapes = n[g] = 30
For equal distribution, there should be a ratio of → n[b]/n[g] = 20/30 = 2/3
Or we can write it as 2 : 3. This means that in each box there should be 2 blueberries and 3 grapes.
The maximum number of bags [x] that Mr. Rodriguez can pack can be calculated as -
2x + 3x = 20 + 30
5x = 50
x = 10
Therefore, with equal distribution of blueberries and grapes, Mr. Rodriguez can pack 10 bags of snacks.

why is iron usually made into alloy for commercial uses?
A iron is too lightweight of a metal
B iron is a scare natural resource
C iron reacts easily with air and water
D iron by itself is to hard
answer fast please
Iron is typically alloyed for commercial uses because it reacts easily with air and water, leading to corrosion. By creating alloys such as steel with added elements like carbon and chromium, iron becomes more robust and rust-resistant, lending itself to a wider range of applications.
The reason iron is usually made into an alloy for commercial uses is that iron reacts easily with air and water, which is option C. Commercial alloys of iron, like steel, are produced by adding elements such as carbon and metals like manganese, chromium, nickel, tungsten, molybdenum, and vanadium. These elements create an alloy that is more resistant to corrosion (rusting), and they can be engineered to have different properties suitable for specific applications. For example, stainless steel contains chromium which helps in forming a protective oxide layer on the surface, thereby protecting the base iron from rusting.
While wrought iron, which is a commercially pure iron containing less than 0.2% carbon, is quite resistant to rust and is malleable and ductile, it has largely been replaced by mild steel. Mild steel, though not as corrosion-resistant as true wrought iron, is more cost-effective and widely available. Therefore, the commercial use of iron predominantly involves its transformation into alloys that benefit from enhanced strength, durability, and corrosion resistance.

What is the APR of a payday loan for $1460 due in 15 days that charges a $90 fee?
Answer:
The answer is 150%
Step-by-step explanation:
Amount of pay day loan = $1460
Also given is that the payday loan for $1460 due in 15 days that charges a $90 fee.
Per day it will charge = [tex]\frac{90}{15}=6[/tex] dollars
For a year it will charge = [tex]365\times6=2190[/tex]
Thus for the due amount of $1460, it will be charged on a rate of =
[tex]\frac{2190}{1460} \times100[/tex] = 150%
Therefore, the APR is 150%.

40 is 160% of what number?
writing this in equation form you have 160% times X = 40
so 160% * x =40
160% as a decimal = 1.60
so 1.60 * x = 40
to find x divide both sides by 1.6
40 /1.6 = 25
the number is 25
