4 x (3+4) because 4x3=12 and 4x4=16
16+12=28 in which 4x7=28 since 3+4 is 7
So 4 x (3+4) would be the correct answer

write an equation in standard form with integer coefficients for the line with slope 6/11 going through the point (-1,-6)
yKpoI14uk [10]
If the slope is 6/11 then, in y=mx+b form, m will be 6/11.  When you multiply 6/11 and -1 you get -6/11.  To get the y (-6), you have to add -60/11.  So in, y=mx+b form the equation is y=6/11x+(-60/11).  To make it standard form, you add negative 6/11x to both sides and then multiply by 11 to get rid of the fractions. So therefore the equation would be:

-6x + 11y = - 60

Find the 7th term 18,6,2…
Veseljchak [2.6K]

If we look at the series, one third of the current term gives the numerical value of the next term.

If we need to express it algebraically, we can write the following equation.

  • a_{n+1}=\frac{a_{n}}{3}

Therefore, our common multiplier can be found as follows. Because this sequence is a geometric sequence.

  • \frac{a_{n+1}}{a_{n}} =r=\frac{1}{3}

In geometric sequences, any term can be written in terms of the first term. Below is an example.

  • a_{n}=a_{1}.r^{n-1}

Since we know the numerical values of the first term and the common factor of the series, we can easily find the seventh term.

  • a_{7}=a_{1}.r^{7-1}
  • a_{7}=18.(\frac{1}{3} )^6
  • a_{7}=\frac{2}{81}

A banner has a length of 10 feet and an area of 7 square feet. What is the width of the banner?
const2013 [10]

Answer:

the width is 0.7 feet

Step-by-step explanation:

Well we know that area = length * width. We know both the area and length, but not the width. Let's substitute the area and length in this equation, and substitute x for the width.

 

7 = 10 * x, or 7 = 10x

 

Now, solve for the width, or x, by dividing both sides by 10.

 

7(/10) = 10x(/10)

 

7/10 = x

 

Simplify 7/10 = 0.7

So the width of the banner is is 0.7 ft!
