Answer:

C and E

Step-by-step explanation:

Since you can't subtract different variables,you would need to just multiply.So in C, the 3 and 2 make 6,add the g making 6g. 3 and 6 make 18 add the h and no variable cancel each other out.

In E,the negatives in 2 and -3 cancel out making 6g and the 9 times -2 makes -18,add the h.

So they each make 6g-18h

A rectangular field is 50 yards wide and 100 yards long. Patrick walks diagonally across the field. How far does he walk

S_A_V [24]

Answer:

Patrick walk approximately 112 yards.

Step-by-step explanation:

Given:

A rectangular field is 50 yards wide and 100 yards long.

Patrick walks diagonally across the field.

Now, to find the distance he walk.

Length of the field = 100 yards.

Width of the field = 50 yards.

Now, to get the diagonal distance we put formula:

$Diagonal = \sqrt{length^2+width^2}$

$Diagonal = \sqrt{100^2+50^2}$

$Diagonal = \sqrt{10000+2500}$

$Diagonal = \sqrt{12500}$

$Diagonal = 111.80$

Therefore, Patrick walk approximately 112 yards.

Mary and Mike went to the store to buy colored pencils for their science class.mike bought a 12-pack for 1.69,and Mary bought a

sweet-ann [11.9K]

12-pack for 1.69 is a better buy

Solution:

Given that, Mike bought a 12-pack for 1.69 and Mary bought a 24-pack for 3.18

We have to find which is the better buy

First we have to find the unit rate

Unit rate is cost of 1 pack

Mike bought a 12-pack for 1.69

Therefore,

Cost of 12 pack = 1.69

Cost of 1 pack is found by dividing 1.69 by 12

$cost\ of\ 1\ pack = \frac{1.69}{12} = 0.14083$

Thus unit rate of Mike is 0.14083 dollar per pack

Mary bought a 24-pack for 3.18

Cost of 24 pack = 3.18

Cost of 1 pack is found by dividing 3.18 by 24

$cost\ of\ 1\ pack = \frac{3.18}{24} = 0.1325$

Thus unit rate of Mary is 0.1325 dollars

On comparing both the unit rate

$0.14083>0.1325$

Thus unit rate of Mike is larger

Thus, 12-pack for 1.69 is a better buy

If c+1/d=5 , what is the value of 30d/2c+2

klemol [59]

Answer:

$d\in R,\hspace{5}d\neq 0$

Step-by-step explanation:

You can solve for any variable. From the first equation, let's solve for c :

$\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1$

Now, replace the value of c into the other equation:

$\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\$

Using distributive property

$\frac{30d}{10d-2+2} =\frac{30d}{10d} =3$

However, keep in mind that this is true for:

$d\in R,\hspace{5}d\neq 0$
