Answer:

Your answer is: [tex]x=\frac{b}{9}[/tex]

or if you are solving for b:  [tex]b=9x[/tex]

Isolate the variable by dividing each side by factors that don't contain the variable.

Hope this helped : )

Yes ofc, but I don’t see anything like a question or a picture of anything.

1285.37

You can use the formula for compound interest:  

P(1+R)^t

P = the principle, the amount of money

(1+R) = the rate, (%) as a decimal plus 1

^t = to the power of the number of years

Substitute the values:

750(1+0.08)^7

750(1.08)^7

1285.37

Step-by-step explanation:

By the root test, the series converges. We have

[tex]\displaystyle\lim_{k\to\infty}\sqrt[k]{\left|(-1)^k\frac{k^3}{3^k}\right|}=\lim_{k\to\infty}\frac{\sqrt[k]{k^3}}3=\frac13\lim_{k\to\infty}k^{\frac3k}=\frac13[/tex]

which is less than 1.

In case it's not clear why [tex]k^{3/k}[/tex] should converge to 1:

[tex]\displaystyle\lim_{k\to\infty}k^{\frac3k}=\lim_{k\to\infty}\exp\left(\ln k^{\frac3k}\right)=\exp\left(\lim_{k\to\infty}\frac{3\ln k}k\right)\to e^0=1[/tex]

Step-by-step explanation:

Answer:

D. 5

Step-by-step explanation:

7 (x + 35) = 280

x + 35 = 280/7

          = 40

x = 40 - 35

  = 5

So it the correct option is D. Sorry I am late!!

Answer:

Sale price of video game with tax = $20.3775

Yes, they both have enough money to purchase the video game.

Step-by-step explanation:

Given that:

Original price of video game = $28.50

Discount on original price = 35%

Sales tax = 10%

Money available with Pat and Henri = $21 each

First of all, let us find out the price as per Pat's method.

Step 1:

Taking 35% of $28.50

[tex]\Rightarrow \dfrac{35}{100}\times \$28.50 = \$9.975[/tex]

Step 2:

Subtract from $28.50 to find the sale price:

$28.50 - $9.975 = $18.525

Step 3:

Take 10% of sale price:

[tex]\$18.525\times \dfrac{10}{100} = \$1.8525[/tex]

Step 4:

Add to sale price to get the final amount to be paid:

$18.525 + $1.8525 = $20.3775

Now, let us use Henri's method:

Step 1:

Find 65% of original price:

[tex]\dfrac{65}{100}\times $28.50 = \$18.525[/tex]

Step 2:

Find 110%:

[tex]\dfrac{110}{100}\times \$18.525 = \bold{\$20.3775}[/tex]

Sale price of video game with tax = $20.3775

Yes, they both have enough money to purchase the video game.

Step-by-step explanation:

Answer:

I think so.

Step-by-step explanation:

If you do the math 2(5-3) exponent 2 - 4 = 4

So if y is 4 you should be correct!

Thb I think you need to know the value of y to solve this question.

Answer:

A. y= 1/4x-5

Step-by-step explanation:

The slope is 1/4 and the y- intercept is -5.

Answer:

I believe the answer would be 240

Step-by-step explanation:

If you divide 60 by 3 you will get 20 which is how much one sweatshirt will cost. Then you multiply 12 by 20 than you should get 240 which might be the answer. I hope that this is helpful and that you get it right.

Answer:

$240

Step-by-step explanation:

3 shirts cost $60

Take 3x4=12

Take $60x4= 240

There you have your answer.

You can also:

60÷3= 20

Each shirt cost $20

Take 12x20= 240

(That is how you will be able to solve the entire table if need be)

Hope this helps!

Answer:

x = 20

Step-by-step explanation:

Exterior angle theorem

Exterior angle = Interior opposite angle 1 + Interior opposite angle 2

(9x + 16)° = 90 + (5x - 14)°

9x + 16 = 90 + 5x - 14

9x - 5x = 90 - 14 - 16

4x = 90 - 30

4x/4 = 60/4

x = 20

Answer:

[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]

Step-by-step explanation:

Coordinates of segment with endpoints J and K are,

J(-4, 9) and K(6, 1)

Midpoint of the segment JK = [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

                                               = [tex](\frac{-4+6}{2},\frac{9+1}{2})[/tex]

                                               = (1, 5)

Slope of JK, [tex](m_1)=\frac{y_2-y_1}{x_2-x_1}[/tex]

                             = [tex]\frac{9-1}{-4-6}[/tex]

                             = [tex]-\frac{4}{5}[/tex]

Let the equation of perpendicular bisector passing through [tex](x_1,y_1)[/tex] and slope [tex]m_2[/tex] is,

[tex]y-y_1=m_2(x - x_1)[/tex]

By the property of perpendicular lines,

[tex]m_1\times m_2=-1[/tex]

[tex]-\frac{4}{5}\times m_2=-1[/tex]

[tex]m_2=\frac{5}{4}[/tex]

Therefore, equation of the line passing through midpoint (1, 5) and slope = [tex]\frac{5}{4}[/tex] will be,

[tex]y-5=\frac{5}{4}(x-1)[/tex]

[tex]y=\frac{5}{4}x-\frac{5}{4}+5[/tex]

[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]

Answer:

  ∠B = 53°

  ∠C = 127°

  ∠D = 127°

Step-by-step explanation:

The trapezoid is isosceles, as indicated by the hash marks on sides AD and BC. This means it is symmetrical about the vertical center-line. Angles on the right will have the same measures as the symmetrical angles on the left.

So, you know immediately that ∠B = ∠A = 53°.

Because AB ║ DC, ∠A and ∠D are supplementary. That is, ...

  ∠D = ∠C = 180° -53°

  ∠D = ∠C = 127°

a. 2(4x + 5y)

(2×4)x + (2×5)y

= 8x + 10y

b. -3(2x + 4y)

(-3×2)x + (-3×4)y

= -6x - 12y
