A box of cereal states that they are 72 cal in a 3/4 cup serving. What is the calories per cup? How many calories are there in 4

Illusion [34]

Answer:

The answer is simple, you have 72 calories as 3/4 of a cup. So you calculate 1/4 of a cup by dividing 72 by 3. We get 24, now we get a total of 96 calories in one cup. Now we have 96x4 which is 384.

1/4 times the sum of a number and −3.2 is 1.8. What is the number?

joja [24]

Answer:

10.4

Step-by-step explanation:

Let the number be x

Sum of x and -3.2 : x + (-3.2) = x - 3.2

1/4 times the sum of a number and −3.2 = (1/4) * (x - 3.2)

$\dfrac{1}{4}* \left( x - 3.2 \right) = 1.8\\\\\Multiply \ the \ whole \ equation \ by \ 4 \\\\4*\dfrac{1}{4} *(x - 3.2) = 1.8*4\\\\\\x - 3.2 = 7.2\\\\Add \ 3.2 \ to \ both \ sides\\\\\\x = 7.2 + 3.2\\$

x = 10.4
