Hey there!
2x + 3x = 20 + x
5x = 20 + x
20 + x = 5x
SUBTRACT x to BOTH SIDES
5x - x = 20x + x - x
5x - 1x = 20x + 1x - 1x
SIMPLIFY IT!
4x = 20
DIVIDE 4 to BOTH SIDES
4x/4 = 20/4
SIMPLIFY IT!
x = 20/4
x = 5
Therefore, your answer is: x = 5
Good luck on your assignment & enjoy your day!

2 1/2 dozen roses cost $40.50 what is the cost of a single rose
,
Answer:
$1.35
Step-by-step explanation:
=> No. of roses in a dozen = 12
=> No. of roses in half dozen = 12/2 = 6
=> No. of roses in 2 1/2 dozen = 2(12)+6 =30
=> 30 roses costs for $40.50
=> Cost of single rose = 40.5/30 = $1.35
order 130 in, 4 yd in 10 ft from greatest to least
Answer: 4 yd, 130 in, 10ft
Step-by-step explanation:
So first you turn everything into inches
130 inches is already in inches.
4 yards = 12 ft
1ft = 12 in
12 *12 = 144 in
so 4 yards is 144 inches
10 ft = 12*10
12*10 = 120
so 10ft is 120 inches
144 inches is the greatest and 120 inches is the least.
The answer needs to be in the original form.

A geometrical series have a constant ratio. The value of r is 4, while the value of a1 is 0.25 and the value of n is 5.
What is geometrical series?A geometrical series is a series of numbers where the quotient of any two consecutive terms of the series is constant.
The given series is a geometrical series which is given as, 0.25, 1, 4, 16, 64.
Now the value of r is the ratio of any two consecutive terms of the geometrical series therefore, the value of r can be written as,
[tex]r = \dfrac{1}{0.25}=4[/tex]
The a1 of a geometrical series is the first term of the series, therefore, the value of a1 can be written as,
a1 = 0.25
The n is the number of terms in a geometrical series, therefore, the value of n can be written as
n = 5
Hence, the value of r is 4, while the value of a1 is 0.25 and the value of n is 5.

the next model of a sport car will cost 14.9% more than the current model. The current costs $52,000. how much will the price increase in dollars ? what will be the price of the next model
Answer:
what will be the price of the next model= 59,748
Step-by-step explanation:
7748 is 14.9% of 52000
Solution:
What is 14.9% of 52000?
Y is 14.9% of 52000
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 14.9% * 52000
Converting percent to decimal:
p = 14.9%/100 = 0.149
Y = 0.149 * 52000
Y = 7748
To find the price for the next model
7748 + 52000
=> 59,748

An expression has numbers, variables, and mathematical operations. The expression that represents the profit made by the organization is 5x-200.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As it is given that the profit is the difference between the revenue and cost. Therefore, the expression that represents the profit can be written as,
[tex]\rm Profit = Revenue - Cost[/tex]
[tex]= (3x^2+4x-60)-(3x^2-x+200)\\\\= 3x^2+4x-60-3x^2+x-200\\\\=5x-260[/tex]

Answer:
25%
Step-by-step explanation:
Think about it like this: $24 multiplied by how much equals $30?
This in equation form would be [tex]24x=30[/tex]
To solve for x, divide both sides by 24: [tex]x=30/24[/tex] or [tex]x=5/4[/tex]
5/4 in percentage form would be 125%, so the dues increased by 25%
