Answer:x=18
Step-by-step explanation:
3(x-5)=x+21
Distribute the 3
3x-15=x+21
Add 15 to each side
3x=x+36
Subtract x from each side
2x=36
Divide each side by 2
x=18

At Best Buy, you buy a 55-inch TV for $499.99. You include the 2-year protection plan for $69.99. Tax in Indiana is 7%. How much tax will you pay? What is your final price?
Answer:
$609.8786
Step-by-step explanation:
Given that :
Cost of TV = $499.99
Protection plan = $69.99
Sales tax = 7%
Sales tax to pay :
Tax % * ( total cost of purchase)
0.07 * (499.99 + 69.99)
0.07 * 569.98
= $39.8986
Total price:
Cost of TV + cost of protection plan + sales tax
499.99 + 69.99 + 39.8986
= $609.8786
Solve the system of linear equations using multiplication. - 3x + 2y 5x - 3y = 17 The solution is
Answer:
Required Answer:-
Given:
5x - 3y = 2
3x - 2y = 4
To Find:
The values of x and y.
Solution:
We have,
→ 5x - 3y = 2 – (i)
→ 3x - 2y = 4 – (ii)
Multiplying equation (i) by 2, we get,
→ 10x - 6y = 4 – (iii)
Multiplying equation (ii) by 3, we get,
→ 9x - 6y = 12 – (iv)
Subtracting (iii) from (iv), we get,
→ -x = 8
→ x = -8
Now, from (i),
→ 5 × (-8) - 3y = 2
→ -40 - 2 = 3y
→ -42 = 3y
→ y = -14
So,
→ (x, y) = (-8, -14)
Answer:
(x, y) = (-8, -14)

Step-by-step explanation:
A carpenter charges $45 for every 50 feet of fence he builds plus a travel charge of $37.50. If the equation, C = 4550F + 37.5 , can be used to determine the total cost, C, of building F feet of fence, how many feet of fence can be built for a cost of $352.50?
Answer:
Step-by-step explanation:
Given the total cost of the building expressed as;
C = 4550F + 37.5
C is the total cost
F is the length of the fence
Given
C = $352.50
Required
The length of the fence F
Substitute into the formula;
C = 4550F + 37.5
$352.50 = 4550F + 37.5
4550F = 352.50 - 36.5
4550F = 316
F = 316/4550
F = 0.0695 feet
hence 0.0695 feet of fence will cost $352.50

(13) The x and y intercept of the line x + y = 1 are 1 and 1 respectively.
(14) The x and y intercept of the line x + 2y = 6 are 6 and 3 respectively.
What is the slope intercept form of an equation ?When any equation is represented in the y = mx +c form, it is called the slope intercept from of the equation.
Here m is slope and c is constant.
(13)
The given equation of line,
x + y = 1
x intercept of the line is at y = 0,
x + 0 = 1
x = 1
y intercept of the line is at x = 0,
0 + y = 1
y = 1
The x and y intercept of the line x + y = 1 are 1 and 1 respectively.
(14)
The given equation of line,
x + 2y = 6
x intercept of the line is at y = 0,
x + 0 = 6
x = 6
y intercept of the line is at x = 0,
0 + 2y = 6
y = 3
The x and y intercept of the line x + 2y = 6 are 6 and 3 respectively.
