What does it mean when two things are opposites?

Answer:

Step-by-step explanation:

For a:

ax = c - by

a = (c - by)/x

For x:

ax = c - by

x = (c - by)/a

For b:

by = c - ax

b = (c - ax)/y

For y:

by = c - ax

y = (c - ax)/b

Answer: 107

Step-by-step explanation:

102.3 can be rounded down to 102 (because the 3 at the end of the number is  less than 5)

4.7 can be rounded up to 5 (because the 7 at the end of the number is greater than 5).

102.3  → estimate = 102

    4.7 →  estimate =   5  

   estimated sum  = 107

Note that estimating the sum is NOT the same as simply adding the numbers and then rounding the sum.

Answer:

x=8.25

Answer:

The expression is (x + 4) yards where x yards represent the initial amount of yards had by tre team

Step-by-step explanation:

In this question, we are told to write an expression which can be used to describe the total yard gained by the team.

Now, before we can write an expression showing the yard gained by the team, we need a variable that will represent the amount of yard they had initially.

Let us represent this by x yard.

By gaining 12 yards in the first play, total amount of yards now become x + 12 yards

Now in the second play, they lost 8 yards and this translates to (x + 12)-8 = (x + 4) yards

Answer:

Answer: 31, hope this helps❤

Step-by-step explanation:

If f(4) = 22, then the value of f(1) is 31.

A sequence in mathematics is a ordered set of objects or numbers which are related with something.

For example, 1, 3, 5, ..... is a sequence of odd numbers.

Given a sequence defined as,

f(n + 1) = f(n) - 3

Given,

f(4) = 22

We know from definition,

f(4) = f(3) - 3

So, f(3) = 22 + 3 = 25

Similarly,

f(2) = 25 + 3 = 28

f(1) = 28 + 3 = 31

Hence the correct option is 31.

Answer:

B(6

Step-by-step explanation:

The number of omelets made by 18 eggs will be 6. The correct option is B.

In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number. The fraction is defined as the division of the whole part into an equal number of parts.

The number of eggs required to make the number of omelets is given in the tables as:-

omelets        eggs

    ?                 18

    3                 9    

    2                 6

    1                  3

The ratio of omelets and egg is calculated as:-

omelets: egg = 3 : 9      

omelets: egg = 1:3

The number of the omelets made by 18 eggs will be calculated as below:-

omelets: egg = 1:3

omelets: 18 = 1:3

omelets = 18 x ( 1 / 3 )

omelets = 6

Therefore, the number of omelets made by 18 eggs will be 6.

Answer:

n = -5

Step-by-step explanation:

Step 1: Write equation

Combine like terms: 2n + 4 = -6

Subtract 4 on both sides: 2n = -10

Divide both sides by 2: n = -5

Answer:

B

Step-by-step explanation:

So we have the equation:

[tex]4xz-4yz=5[/tex]

And we want to find the value of 5/4x in terms of x and y.

From our original equation, let's factor out a 4z from the left. So:

[tex]4z(x-y)=5[/tex]

Now, divide both sides by 4z:

[tex]x-y=\frac{5}{4z}[/tex]

Therefore, the expression that represents 5/4z is x-y.

The correct answer is B.
