Answers

Answer 1

Answer:

A. 3

B. 4.5

Explanation:

A. 2(5x - 3) = 24

10x - 6 = 24

then add six on both sides

U get 10x = 30

divide 10 on both sides

U get x is 3

B. 5(2x + 1) = 50

10x + 5 = 50

minus five on both sides

10x = 45

divide by 10 on both sides

The answer is x = 4.5

Which is true about the polynomial –3xy2 + 5x?y?

Answers

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

» Which expression shows 35 + 15 written as a product of two factors?

Answers

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)

Given:15y+7=12-20y prove:y=1/7 (I just need the prove thanks)

Answers

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

how do i find angle 1 without angle 2 and only the 70?

Answers

Angle 1 is vertical to 60° meaning that angle 1 is equal to 60°.
All triangles’ angles always add to 180 degrees. Since angle 1 is across from the angle measuring 60 degrees, angle 1 will measure 60 degrees. To find angle 2, you can add 70 and 60, which is equal to 130, and subtract 130 from 180. In other words. Angle 1 would measure 60 degrees and angle 2 would measure 50 degrees. To find angle 3 you can add 60+40=100 and subtract that from 180: 180-100=80 degrees. Hope that helped!

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.

Answers

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.
