(1)

we are given

$\frac{y}{6} =x$

we can find for y

multiply both sides by 6

$\frac{y}{6}*6 =6*x$

$y=6x$

we can see that y is directly proportional to x

so, option-D........Answer

(2)

y varies inversely with x

so, we can write it as

$y=k\frac{1}{x}$

now, we are given

y=5 when x=2.5

so, we can plug it here

$5=k\frac{1}{2.5}$

and then we can solve for k

$5*2.5=2.5*k\frac{1}{2.5}$

$k=12.5$

now, we can plug back

$y=\frac{12.5}{x}$

we can plug x=20

$y=\frac{12.5}{20}$

$y=0.625$ .............Answer

(3)

we are given

The current, I, in a circuit varies inversely with the resistance, R

so, we can write it as

$I=\frac{k}{R}$

we have R=12 when I=3

so, we can plug it

$3=\frac{k}{12}$

now, we can solve for k

$3*12=12*\frac{k}{12}$

$k=36$

now, we can plug back

$I=\frac{36}{R}$

we can plug R=6

$I=\frac{36}{6}$

$I=6$ ................Answer

Yesterday, the temperature at noon was 43.6 °F. By midnight, the temperature has decreased by 15.3 degrees. What was the tempera

ELEN [110]

Answer:

Temperature at midnight is $-15.9$ °F.

Step-by-step explanation:

Given: The temperature at noon was $43.6$ °F. By midnight, the temperature has decreased by $15.3$ degrees.

To find: The temperature at midnight.

Solution:

The temperature at noon was $43.6$ °F.

Now, by midnight, temperature has decreased by $15.3$ degrees.

So, first we need to convert the temperature in °F.

We know that, $F=\frac{9}{5}C+32$ , where F is temperature in Fahrenheit and C is temperature in Celsius.

So, $F=(\frac{9}{5} \times 15.3)+32$

$\implies F=59.5$

So, by midnight, temperature has decreased $59.5$ °F

Therefore, temperature at midnight is $43.6-59.5=-15.9$ °F

Hence, temperature at midnight is $-15.9$ °F.

One roll of yarn is used to make 1/5 of a blanket. How many rolls would you use in order to make 65 blankets?

vekshin1

325 rolls of yarn. it takes 5 rolls to make one blanket.
so 5 x 65= 325 rolls of yarn

X+2y + z = 4<br> 1. 4y - 3z = 1<br> y + 5z = 6

Feliz [49]

Answer:

The values of x = y = z = 1

Step-by-step explanation:

Given three linear equation as ,

x + 2y + z = 4 .......a

4y - 3z = 1 .......b

y + 5z = 6 ........c

Now solve eq a and b first

4y - 3z = 1 × 5

y + 5z = 6 × 3

Or, 20y - 15z = 5

3 y + 15z = 18

so ,(20y - 15) + (3y +15 ) = 5 +18

or, 23 y = 23

∴ y = 1

Now put this y value in eq c

so , 1 + 5z = 6 ,

Or, 5z = 6-1 =5

∴ z = 1

Again put this y and z value in eq a

so, x + 2(1) + (1) = 4

Or, x = 4 -3

∴ x = 1

Hence from the above solutions , the value of x = y =z = 1 Answer

Answer to -5x-6x<8-8n-n

EastWind [94]

First...
$Simplify\;-5x-6x \ \textgreater \ \mathrm{Add\:similar\:elements:}\:-5x-6x=-11x$

$Simplify\;8-8n-n \ \textgreater \ \mathrm{Add\:similar\:elements:}\:-8n-n=-9n$
$8 - 9n$

$-11x\ \textless \ 8-9n$

$\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)} \ \textgreater \ 11x\ \textgreater \ -8+9n$

$\mathrm{Divide\:both\:sides\:by\:}11 \ \textgreater \ \frac{11x}{11}\ \textgreater \ -\frac{8}{11}+\frac{9n}{11}$

$Simplify \ \textgreater \ x\ \textgreater \ \frac{-8+9n}{11}$

Hope this helps!
