Answer: 13y - 55

Step-by-step explanation:

Given

7 (3y - 5) - 2 (10 + 4y)

Expand parentheses and apply the distributive property

=7 · 3y - 7 · 5 - 2 · 10 - 2 · 4y

=21 y - 35 - 20 - 8y

Move like terms together

=21y - 8y - 35 - 20

Combine like terms

=13y - 55

Hope this helps!! :)

Please let me know if you have any questions

a. x + 13 = 0

x = -13

x-7= 0

x= 7

b. 2x +3 = 0

2x = -3

x= -3/2 or -1.5

3x -7 = 0

3x = 7

x = 7/3

c. x = 0

or x = 3

these you have to change it into that form first

d. x= 5

or x = 0

e. x= 7

or x = -5

f. x = 1/3 or -5

Answer:

Step-by-step explanation:

(2n³ - 3n⁴ + 7n) - (n³ - 8n⁴ - 7n) = 2n³ - 3n⁴ + 7n - n³ + 8n⁴ + 7n

  {Here -1 is distributed }

                                                  = 2n³ - n³ - 3n⁴ + 8n⁴ + 7n + 7n

                   {Combine like terms}

                                                  = n³ + 5n⁴ + 14n

Answer:

The answer is: n^3 + 5n^4 + 14n

Step-by-step explanation:

Here is your answer . Hope this helps.

Answer:

600 miles in a day.

Step-by-step explanation:

Variable x = number of miles

Company A: 140 + 0.80x

Company B: 80 + 0.90x

Set up an equation:

140 + 0.80x = 80 + 0.90x

Isolate variable x:

60 + 0.80x = 0.90x

60 = 0.10x

600 = x

Check your work:

140 + 0.80(600) = 80 + 0.90(600)

140 + 480 = 80 + 540

620 = 620

Correct!

Answer:

y + 7 = 1/3 (x + 5)

Step-by-step explanation:

The format for writing a point-slope equation is:  y - y1 = m(x - x1).

Step-by-step explanation:

[tex]y - y1 = m(x - x1)[/tex]

where, m = 1/3, x1 = -5 and y1 = -7

[tex]y -( - 7) = \frac{1}{3} (x - ( - 5))[/tex]

[tex]y + 7 = \frac{1}{3} (x + 5)[/tex]

[tex]y = \frac{1}{3} x + \frac{5}{3} + 7[/tex]

[tex]y = \frac{1}{3} x + \frac{26}{3} [/tex]

[tex]y = \frac{1}{3} (x + 26)[/tex]

Answer:

96

Step-by-step explanation:

a= 6 b = - 2

So just subsitute all the a and b into the number they gave

11(6) + 2(3(6)+4(-2)) - 5(-2)

66+ 2(10) +10

66+20+10

96

Just be careful with your positive and negatives

Answer:

4/5

Step-by-step explanation:

What a unique handwriting you have there. Anyways for this types of questions you just have to imagine a right-angled triangle and write down the values and an angle (2A).

First, to find height of the triangle, you can try using Pythagorean theorem, √(5²-3²) and you'll get the value 4.

Remember the formula,

sin a = opposite/hypothenuse.

Substitute the values in,

sin 2A = 4/5

Answer:

Step-by-step explanation:

Factor into primes

32: 2*2*2*2*2

48: 2*2*2*2*3

64: 2*2*2*2*2*2

The highest common factor is 2*2*2*2 = 16

Step-by-step explanation:

Answer:

L,J, and K are collinear

Step-by-step explanation:

Answer:

option D

Step-by-step explanation:

y-intercept=-8

point(0,-8)

m=4

Using point slope form:

y-y1=m(x-x1)

y-(-8)=4(x-0)

y+8=4x

y=4x-8

5^4 /5

Use the exponent rule x^a/x^b = x^a-b

5^4/5 = 5^4-1 = 5^3

Answer as a positive exponent is 5^3

Answer:

<C+83=90 [ sum of complementary angles ]

<C=90-83

<C=7

Now,

<C+83=180 [ sum of supplementary angles ]

<C=180-83

<C=97

Answer:

60π in²

Step-by-step explanation:

Inner Circle:

r = 2 in

Area of inner circle = πr²

        = π* 2 * 2

       = 4π   in²

Middle circle:

r = 6 + 2 = 8 in

Area of middle circle = π * 8 * 8

                                    = 64π in²

Area of shaded region =  area of middle circle -area of inner circle

                                       = 64π - 4π

                                       = 60π in²

Answer:

A = 60pi

Step-by-step explanation:

the radius of the smallest circle is 2 inches so that would give us an area of 4pi. the distance in the shaded part is 6 inches, since we're wanting to find the area of the shaded part, we'll add the radius of the smallest circle, 2 inches, and add it to the length of the shaded circle, 6 inches, to get a radius of 8 inches. plug 8 inches into the formula and youll get 64pi then subtract the 4pi from 64pi and youll get 60pi, which is the area of the shaded part of a circle.

Step-by-step explanation:

If the number is represented by x, then

Answer:

-5

Step-by-step explanation:

5x+23= -2x-12

Add 2x to the other side

7x+23= -12

Subtract 23 from the other side

7x= -35

Divide 7 from the other side

x= -5
