Which pair shows equivalent expressions?
213x+2) - 23x+1
O 243x+2) = 5x+4
o 213x+4)=x+2
0 23x+4) = 2£x+8
2.
Given:
The pair of expressions in the options.
To find:
The pair that shows equivalent expressions.
Solution:
We have,
[tex]2\left(\dfrac{2}{5}x+2\right)[/tex]
By using distributive property, we get
[tex]2\left(\dfrac{2}{5}x+2\right)=2\left(\dfrac{2}{5}x\right)+2(2)[/tex]
[tex]2\left(\dfrac{2}{5}x+2\right)=\dfrac{4}{5}x+4[/tex]
So, option A is incorrect and option B is correct.
We have,
[tex]2\left(\dfrac{2}{5}x+4\right)[/tex]
By using distributive property, we get
[tex]2\left(\dfrac{2}{5}x+4\right)=2\left(\dfrac{2}{5}x\right)+2(4)[/tex]
[tex]2\left(\dfrac{2}{5}x+4\right)=\dfrac{4}{5}x+8[/tex]
So, options C and D both are incorrect.
Therefore, the correct option is B.
The correct pair of equivalents expressions is B.
Multiplication of expressions
To solve the question, one must have knowledge about the multiplication of expressions.
When you have an expression being multiplied by a value, you multiply all the terms of the expression by that value, so that:
[tex]a (x + y) = ax + ay[/tex]
Thus, performing this multiplication for all alternatives we have:
a) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 4[/tex]
b) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 4[/tex]
c) [tex]2 (\frac{2}{5}x + 4) = \frac{4}{5}x + 8[/tex]
d) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 8[/tex]
So, the only expression that correctly corresponds to the answer is that of alternative B.

How many ounces of coffee can be bought for $1.11 if 2 pounds of coffee costs $5.92
Answer:
6 Ounces!
Step-by-step explanation:
$ 5.92 you get 2 pounds
1.11 you will get 2*1.11/5.92
= 0.375 pounds
1 pound = 16 ounzes
0.375 pounds = 16*0.375
= 6 ounces
Hope I helped !
The 6 ounces of coffee you can buy for $1.11 if 2 pounds of coffee costs $5.92 the answer is 6 ounces.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
2 pounds of coffee costs $5.92
Let x be the amount of coffee you get in $1.11
The proportion will be equal:
2/x = 5.92/1.11
To get the value of x,
On cross multiplication:
2×1.11 = 5.92x
5.92x = 2.22
x = 2.22/5.92
x = 0.375 pounds
As we know,
1 pound = 16 ounces
0.375 pounds = y ounces
y = 16x0.375
y = 6 ounces
Thus, the 6 ounces of coffee you can buy for $1.11 if 2 pounds of coffee costs $5.92 the answer is 6 ounces.

A shoe store marks up its merchandise by 38%. What was the selling price of a pair of shoes whose wholesale price is $24.50?
Answer:
SP = $33.81
Step-by-step explanation:
Given that,
The wholesale price of a shoe = $24.50
A shoe store marks up its merchandise by 38%.
We need to find the selling price of a pair of shoes. It can be given by :
SP = wholesale price + 38% of wholesale price
[tex]SP=24.5+38\%\times 24.5\\\\=24.5+\dfrac{38}{100}\times 24.5\\\\=\$33.81[/tex]
So, the selling price of a pair of shoes is $33.81.

the perimeter of a parallelogram is 64 meters .The width of the parallelogram is 8 meters less than its length .Find the length and the width of the parallelogram (x-8)
Answer:
The length of the parallelogram is 18 meters
The width of the parallelogram is 16 meters
Step-by-step explanation:
The perimeter of a parallelogram is 68 meters
LEt x be the length of the parallelogram
Width is 2 meters less than its length
Width =x-2
Perimeter of parallelogram = 2(length + width)
Perimeter of parallelogram =
