PWEASE HELP ME!! I need it ASAP

Mathematics
1 answer:
dem82 [27]3 years ago
5 0

Answer:

V=6/13.5

Step-by-step explanation:

8-8.5(v)=6v+2-v

We move all terms to the left:

8-8.5(v)-(6v+2-v)=0

We add all the numbers together, and all the variables

-8.5v-(5v+2)+8=0

We get rid of parentheses

-8.5v-5v-2+8=0

We add all the numbers together, and all the variables

-13.5v+6=0

We move all terms containing v to the left, all other terms to the right

-13.5v=-6

v=-6/-13.5

v=6/13.5

<em>I hope this helps. </em>

Fran has 7 sheets of paper for a colouring project. If she only uses 1/3 of a sheet of paper per drawing how many drawings can s
Sav [38]
So we can make an equation for this, being 7=1/3x, as that effectively says she can make 3 drawings per page.

Knowing this, we can multiply it by 3 to get x=21 (since if she can draw 3 drawings per page, we can imagine that if each drawing took a page she would need 3 times the pieces of paper), therefore she can make 21 drawings.

40.51x+12.45y=666.64
irga5000 [103]

Answer:

The graph of the equation 40.51x+12.45y=666.64 is attached with the answer where the horizontal axis represents the X axis and the vertical axis represents Y axis.

To plot the graph physically just find two points lying on the line. Mark the points on the graph sheet and then join them. This will give you the line represented by the equation.

To find points on the line assume the value of any one variable, substitute it in the equation, then solve the equation to find the value of other variable. For example : assume y = 1; substitute the value of y in the equation;

⇒ 40.51x + 12.45×1 = 666.64

⇒ 40.51x = 666.64 - 12.45

⇒ 40.51x = 654.19

⇒ x = \frac{654.19}{40.51}

⇒ x ≈ 16.149

Therefore point ( 16.149 , 1 ) lie on the graph of the equation.

***Only two points are required to plot this graph just because it represents a straight line, that we can conclude just by observing the equation. If in an equation the power of x is 1 or 0 and power of y is 1 or 0 then only it will represent a straight line in 2-D plane.***

HELP PLEASE!!! I need help with this question!
AlexFokin [52]

Answer:

\large\boxed{PS=10\sqrt5}

Step-by-step explanation:

ΔPQS, ΔRQP and ΔRPS are similar (AA). Therefore the sides are in proportion:

\dfrac{QR}{RP}=\dfrac{RP}{RS}

We have:

QR=5,\ RS=20

Substitute:

\dfrac{5}{RP}=\dfrc{RP}{20}                <em>cross multiply</em>

RP^2=(5)(20)\\\\RP^2=100\to RP=\sqrt{100}\\\\RP=10

Use the Pythagorean theorem:

PS^2=PR^2+RS^2

Substitute:

PS^2=10^2+20^2\\\\PS^2=100+400\\\\PS^2=500\to PS=\sqrt{500}\\\\PS=\sqrt{100\cdot5}\\\\PS=\sqrt{100}\cdot\sqrt5\\\\PS=10\sqrt5

If x=82902, what is... x*6930+93945*x/7?
olganol [36]

Answer: 1194677035.714285

Step-by-step explanation:

= {(82902 * 6930)+(93945*82902)} / 7

= (574510860 + 7788228390) / 7

= 8362739250 / 7

= 1194677035.714285
