3-5x=2
or, -5x=-1
or, x= 1/5
The value of x is 1/5 for equation 3 – 5x = 2
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 3 – 5x = 2
Three minus five times of x equal to two
We need to solve for x
3 – 5x = 2
Subtract 3 from both sides
3-3-5x=2-3
-5x=-1
Divide both sides by -5
x=-1/-5
x equal to one by five
x=1/5
Hence, the value of x is 1/5 for equation 3 – 5x = 2

Damarcus and Xavier went to the arcade to play their two favorite games. Damarcus played 4 rounds of game 1 and 6 rounds of game 2 for $18.00. Xavier played 5 rounds of each game for $20. What is the cost of game 1? A. $1.00 B. $2.00 C. $3.00 D. $4.00
Answer:
The correct option is (c).
Step-by-step explanation:
Let x and y denote the cost of game 1 and game 2 respectively.
ATQ,
4x+6y = 18 ....(1)
5x + 5y = 20 ....(2)
Multiply equation (1) by 5 and equation (2) by 4.
20x+30y = 90 ....(3)
20x + 20y = 80 ....(4)
Subtracting equation (3) and (4)
20x+30y - (20x + 20y) = 90-80
20x-20x+30y-20y = 10
10y = 10
y = 1
Put the value of y in equation (1).
4x+6(1) = 18
4x = 18-6
4x = 12
x = 3
Hence, the cost of game 1 is $3.00

During the summer, Breanna works at a coffee shop. She saves 75% of her earnings to buy new school clothes. If Breanna earns $750, what is the best estimate for the amount of money she saves to buy clothes?
Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5
Step-by-step explanation:
Given: Breanna saves 75% of her earnings to buy new school clothes.
Earnings for Breanna = $ 750
The amount of money she saves to buy clothes = 75% of 750
= 0.75 x 750 [75%= 0.75]
= $ 562.5
Hence, the best estimate for the amount of money she saves to buy clothes = $ 562.5

What is the value of x?
Please help
Step-by-step explanation:
[tex]360 = 60 + 4x \\ 360 - 60 = 4x \\ 300 = 4x \\ \frac{300}{4} = \frac{4x}{4} \\ x = 75[/tex]
The total internal angle of the polygon is 360°. Since there are 4 unknown angles but the same, we would just add all those to 60° to equal a full 360°.
If f(x) = 2x²–5x+3, find f(x+1)
Answer:
[tex]2x^{2}[/tex]-x
Step-by-step explanation:
To find (x+1) substitue x+1 into the function.
1. 2(x+1)^2-5(x+1)+3: Substitution
2. 2x^2+4x+2-5x+5+3: First do binominal expansion theorem for 1st one then distrubtive property for the first and second one.
3.Combine like with like
[tex]2x^{2}[/tex] , 4x+(-5x)= -x, 2-5+3=0 so
f(x+1)= [tex]2x^{2}[/tex]-x
