Answer: there are eight blocks hidden in the cup.
Step-by-step explanation:
seeing that we don’t know how many blox are in the cup The cup would be a variable in this situation.
x + 4 = 12 cubes
to find your answer you would’ve solve for X, a.k.a. the cup.
x + 4 = 12 cubes
first you would do the inverse operation of addition so instead of adding four you subtract four from four, so that it cancels out. Whatever you do to one side you have to do to the other side so you would have to subtract 4 from The previous 12 cubes.
X = 12 - 4
and your final answer would be 8 cubes
x = 8
there are eight blocks/cubes hidden in the cup

1. If kwame eats 3 slices and the family eats 18 slices thats a total of 21 slices. Each pizza is cut into eighths so there has to be 8 slices to each pizza. There are 3 slices left over for a total of 24 when the eaten slices are added to the left over slices. 24 divided by 8 is 3 pizzas.

anyone know inverse operations, cause I am confused, I looked online and it said
Example: 20 + 9 = 29 can be reversed by 29 − 9 = 20 (back to where we started)
And the other way around:
Example: 15 − 3 = 12 can be reversed by 12 + 3 = 15 (back to where we started)
so like when do we do the 2nd way or can we just do either one of them???
Answers
Answer:
For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.
Inverse operations are also very helpful for linear equations.
To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.
Ex:
13 - 2 = 11 (now change plus to minus)
13 + 2 = 11 (not the answer yet)
Now we switch the first number with the answer!
11 + 2 = 13

A _____________ ratio in any proportional relationship.
Answers
Answer:
a proportional relationship is look at the different values that the variables take on when one variable is one value, and then what is the And then take the ratio between them. and you see y to x, or y divided by x-- the ratio of y to x
If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Writing an Equation to Represent a Proportional Relationship. An expression of equality of ratios is called a proportion. The proportion expressing the equality of the ratios A:B and C:D is written A:B = C:D or A:B::C:D. A is to B as C is to D.

[tex]4^{8}[/tex] × 4² = [tex]4^{(8+2)}[/tex]
