Answer: y = 25

Explanation:

2x+5 = 3x - 33

x = 38

2x+5 + 4y-1 = 180

2(38) + 5 + 4y - 1 = 180

y = 25

Answer:

[tex]y^2-\frac{7}{2}y+3[/tex]

Step-by-step explanation:

Given polynomial is,

6y² - 7y - 2

Fro the zeros of the given polynomial,

6y² - 7y - 2 = 0

6y² - 4y - 3y - 2 = 0

2y(3y - 2) - 1(3y - 2) = 0

(2y - 1)(3y - 2) = 0

(2y - 1) = 0

y = [tex]\frac{1}{2}[/tex]

(3y - 2) = 0

y = [tex]\frac{2}{3}[/tex]

Therefore, zeros of this polynomial are m = [tex]\frac{1}{2}[/tex] and n = [tex]\frac{2}{3}[/tex]

If a polynomial has zeros as [tex]\frac{1}{m}[/tex] and [tex]\frac{1}{n}[/tex] then the zeros will be [tex]\frac{3}{2}[/tex] and 2.

Polynomial will be,

[tex](y-\frac{3}{2})(y-2)[/tex]

= [tex]y(y-2)-\frac{3}{2}(y-2)[/tex]

= [tex]y^2-2y-\frac{3}{2}y+3[/tex]

= [tex]y^2-\frac{7}{2}y+3[/tex]

Answer:

[tex]11\sqrt{797}\pi[/tex]

Step-by-step explanation:

[tex]A=\pi r \sqrt{h^2+r^2}[/tex]

the radius is 22/2 = 11 in

h is 26 in

substitute: [tex]\pi \left(11\right)\sqrt{\left(26^2\right)+\left(11^2\right)}[/tex]

= [tex]11\sqrt{797}\pi[/tex]

Answer:

286π in²

Step-by-step explanation:

The lateral area (A) of the cone is calculated as

A = πrs ( r is the radius and s the slant height )

Here r = 22 ÷ 2 = 11 and s = 26 , then

A = π × 11 × 26 = 286π in²

Answer: 3(x)≥15 →x≥5

Step-by-step explanation:

Set it up with x as the number of days. Then multiply that by 3, so that you get 3(x). This will show that for an x amount of days, you ran 3 miles. then set it to MORE THAN or EQUAL TO 15. Then divide both sides by 3, and you get the above answer.

Answer:

Sara will have a 3,360 interest fee.

Step-by-step explanation:

4% of 1,400 is 56. 56 X 60 = 3,360

Answer:

x = -1

y = 2

Step-by-step explanation:

x + y = 1

y = -x + 1

y = -x + 1  (Multiply this by -1)

y = 3x +5

-y = x - 1

y = 3x +5

0 = 4x + 4

4x = -4

x = -1

x + y = 1

-1 + y = 1

y = 2

Answer:

3 whole 1/3

So to convert mixed to improper, you multiply the denominator with the whole number and then add your answer to THAT to the numerator

Like 3(d) x 3(w)=9

9(ans) + 1(n)= 10

So 10 is your answer and since the denominator always stays the same.it'll remain three and your final answer will be:

10/3

Answer:

A) x > 7

Step-by-step explanation:

Since it's more than, the inequality would be >

Since it's >, that means it's an open circle

So,

x > 7

Answer:  1. Mary Ann has saved $2 more than Carlos

Step-by-step explanation:

He has $26 after 3 hours

she has...

y=6(3)+10

y=18+10

y=28

so

28-26=2

Answer:

D. –x^4 + 6x^3 + 7x^2 – 4x – 4

Step-by-step explanation:

When writing in standard form you have to put the monomials from greatest to least according to their exponent.

[tex]-x^4+6x^3+7x^2-4x-4[/tex]

The first number is [tex]-x^4[/tex] because 4 is the greatest exponent we see, then comes [tex]+6x^3[/tex] which is next because it has the second greatest exponent. And so on and so on.

Answer:

C

Step-by-step explanation:

We are given

The student council earned $1.25 for every cup of hot chocolate it sold

and $0.75 for every cup of apple cider it sold

total number of cup is 375

We can see that first term is 1.25x

and we have

The student council earned $1.25 for every cup of hot chocolate

so, to find total cost of hot chocolate , we multiplied 1.25 with x

that's why

x must be the number of cups of hot chocolate sold

So the answer must be C

Answer:

The answer is D

Hope this helps!!!!

Answer:

105

Step-by-step explanation:

x + 25 + 80 = 180

x + 105 = 180

x = 75

x + y = 180

75 + y = 180

y = 105

Answer:

10ft

Step-by-step explanation:

volume= 502 ft³

or, πr²h= 502ft³

or, h= 502/(π×4²)

or, h= 9.98~10

Answer:

15.9

Step-by-step explanation:

because the x side it's the same as 15 but it's slanted a little bit out so there is a bit more to 15

Answer:

A

Step-by-step explanation:

Answer:

Say that the shape is a parallelogram with equal length sides;

AB = CD

ABD = CDB as the bisecting lines (you have drawn) prove ABD : CDB are both isosceles triangles.

Therefore ABD = ADB

Draw the shape's diagonals as each others' perpendicular bisectors;  

Draw the shape's diagonals bisect both pairs of opposite angles.

If two non congruent angles were given in example 70 degree and 110 degree then say M ∴ = (1/2 )(M∴BAD) = 35  =  (1/2 )(M∴BEF) = 35

and do the same for  1/2(M∴ABC) = 55 = 1/2 (M∴CDA) = 55

Answer:

Amount A = RS 1,000

Step-by-step explanation:

Given:

5% of sum amount is RS 50

Find:

Amount

Computation:

Assume;

Unknown Amount = A

A x 5% = 50

A = 50 / 5%

A = 50 / 0.05

Amount A = RS 1,000

Answer:

5 miles

Step-by-step explanation:

It is a right triangle, with 3 miles down, and 4 miles to the right

the shortest distance would be and southeast line.

Using the Pythagorean theorem, you get:

3^2 + 4^2 = x^2

9 + 16 = x^2

25 = x^2

x = 5

Answer:

R:  (16, 2)

Step-by-step explanation:

Let (x, y) be the point R

(x - 10)/2 = 3       and (y + 12)/2 = 7

x - 10 = 6                     y + 12 = 14

x = 16                           y = 2

R:  (16, 2)

Answer:

The answer is: the domain of the function that show the population-growing per day is

\mleft{

[tex]x \geqslant 0[/tex]

\mright}

Because the domain is the time, in this cases the days.

Answer:

125 and 55

Step-by-step explanation:

The total angle degree of (2x+3) and (x-6) is 180. So, you add both, and set the equation equal to 180 degrees.

2x+3+x-6=180

3x-3=180

3(x-1)=180

x-1=60

x=61

Substitute that for your angles, and you get your answers.
