Answer:

6(4)(5) = 120 units³

Step-by-step explanation:

From the options, I deduced that the prism is a rectangular prism. Then, its volume is computed as follows:

Volume = length*width*height

where length, width and height are 6, 4 and 5 length unit, respectively. Therefore, its volume is:

Volume = 6*4*5 = 120 cubic unit

A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.

Alex Ar [27]

Answer:

$B = 4x + 8$

A box = $11

Step-by-step explanation:

Given

$Total = 7x + 13$

Represent the first order with A and the second with B.

So, we have:

$A = 3x + 5$

Solving (a): Find B.

To find B, we make use of:

$A + B = Total$

Make B the subject

$B = Total - A$

Substitute values for Total and A

$B = 7x + 13 - (3x + 5)$

Open bracket

$B = 7x + 13 - 3x - 5$

Collect Like Terms

$B = 7x - 3x + 13 - 5$

$B = 4x + 8$

Solving (b): Cost of a box of light bulb

This means that:

$Total = 90$

Substitute 7x + 13 for Total

$7x + 13 = 90$

Collect Like Terms

$7x = 90 - 13$

$7x = 77$

Make x the subject

$x = \frac{77}{7}$

$x = 11$

If r and s are positive integers, each greater than 1, and if 11(s-1) =13(r-1), what is the least possible value of (r+s)?

Tresset [83]

Answer:

The least value of (r+s) is (12+14)=26

Step-by-step explanation:

Well, first let us solve equation of 11(s-1)=13(r-1), which results in 11s-11=13r-13. Hence, 11s+2=13r. It is stated that r and s both are integers and greater than 1.

To make sure that r and s are integers, the least value of s must be equal to 14 (s=14) then the least value of r becomes 12 (r=12).

Finally, the least value of (r+s) is (12+14)=26.
