Given:15y+7=12-20y prove:y=1/7 (I just need the prove thanks)
Answer:
15y+7=12-20y (add 20y to both sides)
35y+7=12 (minus 7 from both sides)
35y = 5 (divide both sides by 35) (5/35=1/7)
y= 1/7
Answer:
64/7 = 64/7 yes y = 1/7
Step-by-step explanation:
To prove this we simply have to plug in!
15(1/7) + 7 = 12 - 20(1/7) (simplify)
15/7 + 7 = 12 - 20/7 (simplify further)
64/7 = 64/7
So yes y = 1/7
The medians of ADEF are DK, EL, and FJ. They meet at a single point M.
(In other words, M is the centroid of ADEF.)
Suppose ML = 9, MJ=8, and DK = 24.
Find the following lengths.
Note that the figure is not drawn to scale.
Answer:
FJ = 24
DM = 16
EM = 18
Step-by-step explanation:
I remember that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side. Therefore the median is split into two parts where one side is always twice as long as the other. So given that segment ML is 8, the other part of the segment (DM) must be 16 as 16 is 2/3 of 24 and 8 is 1/3 of 24 and 1/3 + 2/3 = 1.
Therefore, since MJ is 8, FM must be twice as long so it is 16. Add them up to get FJ, and 8 + 16 is 24.
Finally for EM, since the longer part of the median is twice the length of the smaller part EM must be 18 since 9 × 2 = 18, and 2/3 of 18 is 27, 9 + 18 = 27.

» Which expression shows 35 + 15 written as a product of two factors?
Answer:
[tex]35 + 15 = 5 * 10[/tex]
The factors are 5 and 10
Step-by-step explanation:
Given
[tex]35 + 15[/tex]
Required
Express as a product of two factors
[tex]35 + 15[/tex]
Start by factorizing the expression:
[tex]5(7 + 3)[/tex]
Add the expression in the bracket
[tex]5(10)[/tex]
Replace bracket with *
[tex]5 * 10[/tex]
Hence:
[tex]35 + 15 = 5 * 10[/tex]
The expression which shows 35 + 15 written as a product of two factors is 5(7 + 3).
What is meant by expression?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.
Let the expression be 35 + 15
Express as a product of two factors
35 + 15
Factorizing the expression we get
5(7 + 3)
simplifying the above expression, we get
5 (10)
Hence:
35 + 15 = 5 × 10
Therefore, the correct answer is option b) 5(7 + 3).
The complete question is:
Which expression shows 35 + 15 written as a product of two factors?
a) 5(6 + 3)
b) 5(7 + 3)
c) 7(5 + 2)
d) 7(5 + 3)

Consider the equation: 3x + 1 – 9 = 3(x + 2) + n.
Give a value of n so that the equation has no solutions.
Explain why you are correct.
answer: n = -14
3x + 1 - 9 = 3(x + 2) + n
<=> 3x - 8 = 3x + 6 + n
<=> 3x - 8 - 3x - 6 = n
<=> n = -14

Which is true about the polynomial –3xy2 + 5x?y?
It is a binomial with degree 3
Explanation:
It has two terms: (−3xy2) and (5x2y) → it is a binomial
The degree of an expression is the largest sum of exponents of variables for any term in the expression.
−3xy2=−3x1y2 has a sum of exponents of variables =3
5x2y=5x2y1 also has a sum of exponents of variables =3
→ the expression has degree 3
A package that is heavier than 11 lb. and 8 oz. will have a label that says "heavy" on it. Gloria packed 6 flower pots to send to her customers. Each of the flower pots weighs 1 lb. and 12 oz. The packing material weighs 5 oz. Will her package be labeled as "heavy"?
Answer:
No, the package will not be labeled "heavy"
Step-by-step explanation:
1) if you multiply 1lb. and 12 oz. by the number of flower pots(I'll be using the variable P), then the expression will be (1lb.P) (12oz.P).
2) then after you get the answer for that, which is 6lb. 72oz. and after that you'll have to add the weight of the packaging, which is 5oz. which the answer is 6lb. 77oz.
3) after, you will then have to get the number of pounds from the ounces if there are more than 16, which there are, so after you get the answer out of that, which is 4 and then you would have 13oz. leftover.
4) you would then have to add your 4lb. to your 6 that you already have, which would be 10lb.
Final) so in the end, you would have 10lb. 13oz.
