Orlov [11]2 years ago
5 0

Answer:

A

Step-by-step explanation:

5 and 7 are both common factors of 35 and 40

Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.

This leaves A and B. Looking at the equation the difference between the two are the + and -

Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer

Whay percent of 25 is 12?
Tcecarenko [31]

Answer:

48% of 25 is 12.

Step-by-step explanation:

To find : what percent of 25 is 12?

Solution : Let x be the percentage of 25 which is 12

So, by the statement

x% of 25 = 12

Now, we have to calculate the value of x

Step 1- Write the expression

\frac{x}{100} \times 25 = 12

Step 2- divide 25 by 100

\frac{x}{4} = 12

Step 3- Cross multiply

x=48

Therefore, 48% of 25 is 12.

What is the value of x so that the ordered pair (x, 1) is a solution to the equation 3x - y = 17 ? A. B.6 C.14 D.20
Alexxx [7]
Its B.6 because when you plug in 1 for y the equation is 3x-1=17 and you have to cancel out y to get 3x=18 by itself because you have to add 1 to the 17 since you canceled it out of the equation then you are left with 3x=18 and you divide both sides by 3 and then 18 divided by 3 is 6 so x=6

Write an equation of the line satisfying the given conditions. Through (1,−5); parallel to 5x=6y+7
evablogger [386]

Answer:

y = 5/6 x - 35/6

Step-by-step explanation:

first convert equation to y = mx + b to get the slope

5x -7 = 6y

5/6 x - 7/6 = y

5/6 is the slope

because the line is parallel, the slope is 5/6

use the point given and simplify

y + 5 = 5/6 (x - 1)

y + 5 = 5/6x - 5/6

y = 5/6x - 5/6 - 30/6

y = 5/6x - 35/6

A right rectangular prism has these dimensions:
DochEvi [55]
Hey there :)

The volume formula of a rectangular prism is
V = height x length x width

Given are:
Length = 1\frac{1}{2} = \frac{3}{2}
Width = \frac{1}{2}
Height = \frac{3}{4}

Lets find the volume:
V = \frac{3}{2} x \frac{1}{2} x \frac{3}{4}
   =  \frac{9}{16} units³

The volume formula of a cube is
V = side³

Given is:
Side = ( \frac{1}{4} )^3  
        = \frac{1}{64} units³

To find how many cubes fit in the rectangular prism, we divide the volumes
Volume of prism divided by volume of cube
\frac{9}{16} ÷ \frac{1}{64}
Since it is a fraction that is involved in division, we find the reciprocal and multiply

= \frac{9}{16}  x  64 
= 36

Your answer will be the 1st option
