B. 10
C. 35
D. 40

9514 1404 393

Answer:

  x = 21

  y = 60

Step-by-step explanation:

We assume the marks are angle measures.

The angles of a linear pair are supplementary:

  (3x +5) +(6x -14) = 180

  9x -9 = 180 . . . . simplify

  9x = 189 . . . . . . add 9

  x = 21 . . . . . . . divide by 9

__

At parallel lines, corresponding angles are congruent.

  y +8 = 3x +5 = 3(21) +5 = 68

  y = 60 . . . . . subtract 8

Let n be the unknown number

Answer:

the number is 49

Step-by-step explanation:

first, write an equation based on the words

4 increased by= 4+

three fifths of a number = [tex]3/5 * n[/tex]

is 49: =49

now, put it together: [tex]4 + 3/5*n=49[/tex]

Now, solve

4 + 3/5*n=49

4-4=0   49-4= 45

3/5*n=45

3/5*n / 3/5= n    45/ 3/5= 75

n=75

Step-by-step explanation:

what is the problem here you don't understand ?

you understand the words "equality" and "inequality" ?

this is all about the question, if something is equal to something else or not - meaning of they are the same or at least the same size.

an expression without an equal ("=") or unequal sign ("<", ">", ">=", "<=", "<>" - if you don't understand these symbols, please ask, they are simply basic keyboard symbols for the scientific symbols) is not any form of that - no equality, and no inequality.

so,

1. is NOT

2. is NOT because it has an equality symbol

3. is a quadratic inequality (when doing the multiplication of both bracket terms, there will be an x×x=x² part) - it has a ">" (greater) symbol

4. is a quadratic inequality (there is a x² term as highest power of x included) - it has a "<=" (smaller or equal) symbol

5. is a quadratic inequality (there is a x² term as highest power of x included) - it has a ">" (greater) symbol

x=2

Answer:

79, 81, 83, and 85

Step-by-step explanation:

x = 1st integer

x+2 = 2nd

x+4 = 3rd

x+6 = 4th

328 = sum

x+x+2+x+4+x+6 = 328

328/4 = 82

The 4 integers are the 2 odd integers on either side of 82 and closest to 82

That would be 79, 81, 83, and 85.

79 + 81 + 83 + 85 = 328

120 = 1 x 120, 2 x 60, 3 x 40, 4 x 30, 5 x 24, 6 x 20, 8 x 15, or 10 x 12. Factors of 120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120. Prime factorization: 120 = 2 x 2 x 2 x 3 x 5, which can also be written 120 = 2³ x 3 x 5.

Step-by-step explanation:

1. In a group of cows and chickens, the number of legs was 14 more than twice the number of heads. The number of cows was:

(a) 5, (b) 7, (c) 10, (d) 12, (e) 14

Solution:

Let the number of cows be x and their legs be 4x.

Let the number of chicken be y and their legs be 2x.

Total number of legs = 4x + 2y.

Total number of heads = x + y.

The number of legs was 14 more than twice the number of heads.

Therefore, 2 × (x + y) + 14 = 4x + 2y.

or, 2x + 2y + 14 = 4x + 2y.

or, 2x + 14 = 4x [subtracting 2y from both sides].

or, 14 = 4x – 2x [subtracting 2x from both sides].

or, 14 = 2x.

or, x = 7 [dividing by 2 on both sides].

Therefore, the number of cows = 7.

Answer:

4

Step-by-step explanation:

When you add them the answer is 1.

Now our equation is X plus 4 minus 2 plus X so we will substitute X to our answer which would be

(1) plus 4 -2 plus (1)

1 plus 4 - 2 plus 1

equals to 4

Our answer is 4

Answer and Step-by-step explanation:

To find the third side, we can use the Pythagorean Theorem.

The theorem states that if a triangle is a right triangle, and we already have two sides, we are able to find the third side.

The Pythagorean Theorem Formula is the following:

[tex]A^2+B^2=C^2[/tex]

A is any of the bases

B is the other base (you can make this the height)

C is the hypotenuse (the longest side)

We are given B and C, so lets plug them into our formula and solve for A.

[tex]A^2 + (4\sqrt{3} )^2=8^2[/tex]

Subtract [tex](4\sqrt{3} )^2[/tex] from both sides of the equation.

[tex]A^2=8^2 - (4\sqrt{3} )^2[/tex]

Now take the square root of both sides of the equation.

[tex]A=\sqrt{8^2 - (4\sqrt{3} )^2}[/tex]

Now plug this into your calculator and solve.

We get the answer to be:

4

Answer:

Step-by-step explanation:

The diameter of the equation of a circle in the xy-plane as shown is 26 units.

The standard form for finding the equation of a circle is expressed as:

[tex]x^2 + y^2 +2gx + 2fy +C= 0[/tex]

For us to get the diameter of the circle, we need to get the radius of the circle first calculated as shown:

[tex]r=\sqrt{g^2+f^2-C}[/tex]

Given the equation of the circle expressed as [tex]x^2 + y^2 - 6x + 8y = 144[/tex]

Compare with the general formula:

2gx = -6x

g = -6/2

g = -3

Similarly;

2fy = 8y

2f = 8

f = 4

C = -144

Substitute into the formula for calculating the radius;

[tex]r=\sqrt{(-3}^2+4^2-(-144)\\r=\sqrt{9+16+144}\\r=\sqrt{169}\\r=13units[/tex]

Get the diameter of the circle

d = 2r

d = 2(13)

d = 26 units

Hence the diameter of the equation of a circle in the xy-plane as shown is 26 units.

Because im right

Answer:

G

Step-by-step explanation:

a + b + c = 80

Express a and c in terms of b using the ratios in fractional form, that is

[tex]\frac{a}{b}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )

3a = 2b ( divide both sides by 3 )

a = [tex]\frac{2}{3}[/tex] b

[tex]\frac{b}{c}[/tex] = [tex]\frac{3}{11}[/tex] ( cross- multiply )

3c = 11b ( divide both sides by 3 )

c = [tex]\frac{11}{3}[/tex] b

Substitute the values for a and c into the original equation

[tex]\frac{2}{3}[/tex] b + b + [tex]\frac{11}{3}[/tex] b = 80 ( multiply through by 3 to clear the fractions )

2b + 3b + 11b = 240 , that is

16b = 240 ( divide both sides by 16 )

b = 15 → G

From the figure shown where MN is parallel to PQ:

m<MSR   =  100°

m<STQ   =  80°

By carefully observing the figure shown:

<MSR is vertically opposite to <NST

Vertically opposite angles are equal

m<NST  =  (17x  +  15)

<NST is alternative to <PTS

Alternative angles are equal

Therefore, m<NST  =  m<PTS

m<NST = 17x + 15

m<PTS  =  19x + 5

17x  +  15   =  19x  +  5

19x  -  17x =  15  -  5

2x   =  10

x   =  10/2

x   =  5

m<NST  =  17x + 15

m<NST  =  17(5)  +  15

m<NST  =  100°

Since m<MSR  =  m<NST

m<MSR   =  100°

m<PTS  =  19x + 5

m<PTS  =  19(5)  +  5

m<PTS  =  100°

m<PTS  +  m<STQ  =  180° (Sum of angles on a straight line)

100   +  m<STQ   =  180

m<STQ   =  180 - 100

m<STQ   =  80°

From the figure shown where MN is parallel to PQ:

m<MSR   =  100°

m<STQ   =  80°

False because if 3 is subtracted from 52, then 49 and 27 more would not equal 49 and 24 more. Putting together two larger numbers is not the same as putting together two smaller numbers.

=======================================================

Explanation:

If we break up 52 into 49+3, then we can do the following rearrangement.

52 + 27 = 49 + 24

49 + 3 + 27 = 49 + 24

3 + (49+27) = 49 + 24

Notice that the 49+27 on the left is clearly larger than 49+24 on the right, mainly due to the 27 being larger than 24.

Then adding on 3 more means that the left side gets even larger.

So without having to add either side and simplify fully, we can see that the left side is larger than the right side. There's no way the two sides are the same number.

----------

Perhaps another quick way is to simply look at the units digits.

The 2 and 7 from 52 and 27 add to 2+7 = 9

The 9 and 4 from 49 and 24 add to 9+4 = 13 and we only care about the 3

The mismatch of the 9 and 3 is more evidence that the two sides aren't the same number.

The domain of the function (cd)(x) will be all real values of x except x = 2.

Step-by-step explanation:

The two functions are c(x)=

So, (cd)(x) =

[tex]( \frac{5}{ \times - 2} )( \times + 3) = 5\frac{( \times + 3)}{ \times - 2} [/tex]
