Step-by-step explanation:
6x - 3 + 3x = 60 + 2x
Combine like terms:
6x - 3 + 3x = 60 + 2x
9x - 3 = 60 + 2x
-2x -2x
-----------------------
7x - 3 = 60

Answer:
9
Step-by-step explanation:
to solve this equation you first have to group the like terms
6x-3+3x=60+2x
6x+3x-2x=60+3
7x=63
then you divide both sides by 7 inorder to remain with the variable x on one side
7x/7=63/7
x=9

if 2y-5x+10=0, find.
(i)y, when x=2
(ii)x, when y=5
Answer:
When x = 2, y = 0When y = 5, x = 4Step-by-step explanation:
PART I: Value of y, when x = 2Given information
x = 2
Given expression
2y - 5x + 10 = 0
Substitute values into the expression
2y - 5(2) + 10 = 0
Simplify by multiplication
2y - 10 + 10 = 0
2y = 0
Divide 2 on both sides
2y / 2 = 0 / 2
[tex]\boxed{y=0}[/tex]
-----------------------------------------------------------------
PART II: Value of x, when y = 5Given information
y = 5
Given expression
2y - 5x + 10 = 0
Substitute values into the expression
2(5) - 5x + 10 = 0
Simplify by multiplication
10 - 5x + 10 = 0
20 - 5x = 0
Add 5x on both sides
20 - 5x + 5x = 0 + 5x
20 = 5x
Divide 5 on both sides
20 / 5 = 5x / 5
[tex]\boxed{x=4}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
(i) x = 2
Substituting value in the equation,
2y - 5(2) + 10 = 0
2y - 10 + 10 = 0
2y = 0
y = 0
(ii) y = 5
Substituting value in the equation,
2(5) - 5x + 10 = 0
10 - 5x + 10 = 0
20 - 5x = 0
20 = 5x
5x = 20
x = 20/5
x = 4

If x = 2y then, 5y - x in terms of y is equal to 3y and when y = 2, the value of 5y - x is 6.
To solve 5y - x in terms of y, we need to substitute the value of x in terms of y. Given that x = 2y, we can replace x with 2y in the expression 5y - x:
5y - x = 5y - (2y)
Now we simplify the expression by subtracting 2y from 5y:
5y - (2y) = 3y
Therefore, 5y - x in terms of y is equal to 3y.
To find the value of the expression when y = 2, we substitute y = 2 into the expression:
3y = 3 * 2 = 6
Thus, when y = 2, the value of 5y - x is 6.

The cost to rent a van is $19.50 per day plus $0.25 per mile. If you have $157 to
rent a van, what is the number of miles that you can drive if you want to rent the van
for 2 days and you want to stay below your budget? Let m represent the number of
miles.
Answer:
92 miles
Write an inequality for the total cost of the rental.
Cost of the rental = 19.50+0.25x<=44
where x is the number of miles driven.
Subtract 19.50 from both sides.
0.25x<=44-19.50
0.25x<=24.5
x<=24.5/0.25

16. There are 36 tables set up for the graduation reception. Each table is
8 feet long. The tables will be covered with paper tablecloths that extend
an extra 3 inches over each end (so they can be taped underneath). What
is the total length of paper needed to cover all the tables?
We have that the total length of paper needed to cover all the tables is
[tex]X=288.5ft[/tex]
From the question we are told that:
Number of tables [tex]n=36[/tex]
Length of table[tex]l=8[/tex]
Extension [tex]e=3 inch =>0.25feet[/tex]
Generally, the equation for the Total length tables is mathematically given by
[tex]l_t=n*l\\\\l_t=36*8[/tex]
[tex]l_t=288ft[/tex]
Therefore with an extension of 0.25ft at both end we have the Total length of tablecloths to be
[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]
[tex]X=288.5ft[/tex]
In conclusion
The total length of paper needed to cover all the tables is
[tex]X=288.5ft[/tex]

What is the equation of a line that passes through (4, 3) and has a slope of 2?
Oy= 2x – 11
Oy=2x-1
Oy= 22 – 5
y= 22 - 7
Answer:
[tex]y=2x-5[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
We're given that the slope is 2. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=2x+b[/tex]
Now, to solve for the b, plug in the point (4,3):
[tex]3=2(4)+b\\3=8+b\\3-8=b\\-5=b[/tex]
Therefore, the y-intercept is -5. Plug this back into [tex]y=2x+b[/tex] as b:
[tex]y=2x+(-5)\\y=2x-5[/tex]
I hope this helps!
(x,y) = (4,3)
m = 2
Solution :-We know that
y = 2x + b
3 = 2(4) + b
3 = 8 + b
3 - 8 = b
-5 = b
Now
We need to find the equation
Equation = y = 2x + b
We have
x = x
y = ?
b = -5
y = 2(x) + (-5)
y = 2(x) - 5
y = 2x - 5
Option C is exactly correct.
B is between A and C, BC=38, and AC=42. Find AB

Answer:
AB = 4
Step-by-step explanation:
AB + BC = AC
Substitute the line segments for their given values:
AB + 38 = 42
Subtract both sides by 38:
AB = 42 - 38
AB = 4
Check your work:
4 + 38 = 42
42 = 42
Correct!
