Answer:
To eliminate the x-terms, multiply the second equation by 2.
To eliminate the y-terms, multiply the second equation by 3.
Step-by-step explanation:
The first step of solving by elimination requires that you eliminate either the x-terms or y-terms by making the two terms have the same coefficient, but opposite signs.
So, if you wanted to eliminate the x-terms, you could multiply the second equation so that its x term has the same coefficient as the x-term in the first equation, but with opposite signs. The x-term in the first equation is 4x. The x-term in the second equation is -2x. They already have opposite signs, so we just need the -2x to become -4x. -4x divided by -2x is 2, thus you would multiply the second equation by 2.
If you wanted to eliminate the y-terms, the process is the same. The y-term in the first equation is -9y and the y-term in the second equation is 3y. Again, they already have opposite signs, we just need 3y to become 9y. 9y divided by 3y is 3, thus you would multiply the second equation by 3.
Answer:
to eliminate x, u would multiply second equation by 2
to eliminate y, u would multiply second equation by 3

Heights of American adult women are normally distributed with mean 63.6 inches and standard deviation 2.5 inches. Find the height of an adult woman that corresponds to the 80th percentile.
Answer:
65.7
Step-by-step explanation:
Given ;
Mean, m = 63.6
Standard deviation, s = 2.5
80th percentile = 80 / 100 = 0.8
The Zscore corresponding to the 80th percentile ; Z < P = 0.842 (Z probability calculator)
Zscore = (x - m) / s
0.842 = (x - 63.6) / 2.5
0.842 * 2.5 = x - 63.6
2.105 = x - 63.6
x = 63.6 + 2.105
x = 65.705
Find the volume of the prism.
Answer:
238m^3
Step-by-step explanation:
Volume = lwh (length times width times height)
so do 4 x 7 x 8 1/2
this gets you 238m^3 (because you have to cube your answer with units)
Simplify: (9x^5)(4x^4)

Chicken tenders generally weigh about 4 ounces each. When we purchased them from the store, we paid $4 per pound (16
ounces) for frozen tenders. French Fries are about $2 per pound. On the Chicken Tender Platter, we put 3 tenders, and aboud
4 ounces of french fries. What is the total food cost of the Chicken Tender platter?
Answer:
i need points
Step-by-step explanation:
ndm
Answer: 3.50
Step-by-step explanation:
4 ounces x 3 tenders = 12ounces so 3 dollars. then 4 ounses so 50 cents. so 3.00 + 0.50= 3.50
what is ³/8 of 1 dollar
Answer:
Step-by-step explanation:
A dollar is 100 cents
3/8 = .375
0.375 * 100 = 37.5
Rounded it is 38 cents.

Factor 16a + 72 to identify the equivalent expression
Hey there, thanks for posting your first question!
If you're asked to factor a polynomial, you need to look for the
greatest common factor between the terms that are involved.
The greatest common factor of 16a and 72 is 8 because 8
is the largest number that can divide into both 16 and 72.
The "a" doesn't qualify because it doesn't appear in every term.
So the 8 factors out.
When that happens, we are left with each term divided by that 8
inside a set of parenthses, I'll show you what I mean.
So we have 8(2a + 9).
I divided the 16a by the 8 and 72 by the 8 and if you
distribute it back you will end up with the original polynomial.
So our answer 8(2a + 9).
simplify the problem (2y−6)^2
Answer:
4y^2-24y+36
Step-by-step explanation:
Expand the expression to simplify, which you do by using the FOIL method, then combining like terms.
(a-b)(a-b) = a^2 - 2ab + b^2
(2y-6)^2
= (2y-6)(2y-6)
= 4y^2 - 12y + 36

Answer:
42
Step-by-step explanation:
Answer:

all measures of a triangle add up to 180
the angle opposite of angle b on the triangle is [tex]48[/tex]°
[tex]48+90+C=180[/tex]
[tex]138+C=180[/tex]

Brown Delivery Company delivers its standard crates using a fleet of vans and trucks. A van can hold up to 20 standard
crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard
crates at one time using 12 vehicles, which system of linear equations could be used to determine the number of vans, x,
and the number of trucks, y, needed for this delivery?
x + y = 12
20x + 35y = 270
x + y = 270
20x + 35y = 12
x + y = 12
35x + 20y = 270
x+y = 270
35x + 20y = 12
Answer:
x + y = 12
20x + 35y = 270
Step-by-step explanation:
Let us represent:
The number of vans = x
The number of trucks = y
From the above question, we are told that:
A van can hold up to 20 standard crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard crates at one time using 12 vehicles.
Hence, our system of equations is given as:
x + y = 12..... Equation 1
20 × x + 35 × y = 270
= 20x + 35y = 270...... Equation 2
