Identify the solution set of the given inequality using replacement set.

Which of the following algebraic expressions is not simplified?

Hunter-Best [27]

Answer:

B. $x+2x$

Step-by-step explanation:

we will verify each options

option-A:

we have

$x+1$

we can see that x and 1 are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-B:

we have

$x+2x$

we can see that 2x and x are same type of terms

so, they are like terms

so, we can combine or simplify it

$x+2x=3x$

So, this expression is not in simplest form

this is TRUE

option-C:

we have

$x^2+x$

we can see that x^2 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-D:

we have

$5x^3-x$

we can see that 5x^3 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

Unit Test / 16 of 25

Rzqust [24]

Answer:

30

Step-by-step explanation:

For the minimum free throws, he must put every throw to the basket.

So, let n be the number of throws for Tuesday, in which all the throws are successful.

So, over both the days, total free throws he makes= 15+n.

Total numbers of throws that went in the basket= 6+n.

As he wants at least 80% of his balls to go in the basket.

So, 6+n is greater than or equal to 809% of 15+n, i.e

$6+n\geq \frac{80}{100}\times (15+n)$

$\Rightarrow 30+5n\geq 60+4n$

$\Rightarrow n\geq 30.$

Hence, the minimum number of free throws required on Tuesday to reach his goal is 30.

An Easter basket contains eggs of three different colors. Find the total number of eggs in the basket if 2 7 of all eggs are gre

mrs_skeptik [129]

Answer:

Total number of eggs in basket = 56

Step-by-step explanation:

Let z be the total number of eggs

Green eggs = $\frac{2}{7}$ × z ........1

Blue eggs = $\frac{1}{4}$ × z .......2

Rest of eggs = 26 ........3

The addition of 1, 2 and 3 is equal to z

$\frac{2}{7}$ × z + $\frac{1}{4}$ + 26 = z

$\frac{8z + 7 z}{28}$ + 26 = z ∵GCF for 4 and 7 is 28

$\frac{15z}{28}$ + 26 = z

15z + (26 × 28) = 28z ∵ multiply both sides by 28

15z + 728 = 28z

28z - 15z = 728 .......... rearranging above equation

13z = 728 ⇒ z = $\frac{728}{13}$ ⇒ z = 56

Total number of eggs = z = 56
