A recipe for 8 servinfs of pudding clls for 2 cups of milk.How many gallons of milk are needed to make enough pudding for 64 ser

I am Lyosha [343]

In order to solve this, we first need to know what the ratio of servings of pudding to cups of milk is. We can see that 8 servings of pudding requires 2 cups of milk, so the ratio is 8/2, which can be reduced to 4/1. This means that for every 4 servings of pudding, we will be adding 1 cup of milk. So all we need to do to find out how many cups would be needed for 64 servings of pudding, we simply need to divide by 4.

64 / 4 = 16

So for 64 servings of pudding, we will need 16 cups of milk. But that's not what the question wants to know, it wants to know how many gallons of milk it would need.

In order to find that out, we have to know how many cups there are in one gallon. There are 2 cups in one pint, there are 2 pints in a quart, and there are 4 quarts in a gallon, so we just have to multiply those numbers, and we get 4 * 2 * 2 = 8 * 2 = 16

There are 16 cups in one gallon, therefore, 64 servings of pudding will require 1 gallon of milk.
Hope that helped! =)

What is the value of x in the equation

MrRissso [65]

Answer:

x = -3

Step-by-step explanation:

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 1.4 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

0.7x - 1.4 = -3.5

→ First multiply everything by 10 to make everything into a whole number

7x - 14 = -35

→ Plus 14 to both sides to isolate 7x

7x = -21

→ Divide both sides by 7 to isolate 7

x = -3

Teresa is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices: co

Sergio [31]

Let x represent the number of miles driven by both individuals.

Now, since COMPANY A will charge Teresa an initial constant fee of $58 and then an additional 40 cents (or $0.4) for every mile driven, we know that:

- if Teresa drives x miles, she will be charged:

$0.4\times x\text{ dollars}$

Therefore, in total, Teresa will be charged by company A the following:

$(58+0.4x)\text{dollars}$

Also, since COMPANY B will charge Teresa an initial constant fee of $40 and then an additional 69 cents (or $0.69) for every mile driven, we know that:

- if Teresa drives x miles, she will be charged:

$0.69\times x\text{ dollars}$

Therefore, in total, Teresa will be charged by company B the following:

$(40+0.69x)\text{dollars}$

Now, the milieage (x) for which both companies A will charge Teresa no more than company does is obtained by relating the expressions for their separate fees as follows:

$(58+0.4x)\text{dollars }\leq(40+0.69x)\text{dollars}$

Thus, we simply the above and solve for x, as follows:

$58+0.4x\leq40+0.69x$

Collect like terms:

$\begin{gathered} 0.4x-0.69x\leq40-58 \\ \Rightarrow-0.29x\leq-18 \end{gathered}$ $\begin{gathered} \Rightarrow x\ge\frac{-18}{-0.29}\ge62.07 \\ \Rightarrow x\ge62\text{ miles} \end{gathered}$
