the sum of two numbers is 98. if the larger number is divided by the smaller the quotient is 4 with a remander of 13. Find the two numbers
Answer: x = 81, y = 17
Step-by-step explanation:
x + y = 98
x/y = 4/13/y
x/y = 4y + 13/ y
x = 98 - y
(98 - y) / y = (4y+ 13) / y
Therefore
98 - y = 4y + 13
Collect like terms
-4y - y = 13 - 98
-5y = -85
Divide both sides by-5
y = 17
x = 98 - y
x = 98 - 17
x = 81
The two numbers x and y are 81 and 17 respectively.
What are the Quotients?Quotients are the number that is obtained by dividing one number by another number.
Dividend ÷ Divisor = Quotients
Given that the sum of two numbers is 98.
Let x and y be the two numbers
x + y = 98
Thus, the larger number is divided by the smaller quotient is 4 with a remainder of 13.
x/y = 4/13/y
x/y = 4y + 13/ y
x = 98 - y
(98 - y) / y = (4y+ 13) / y
Therefore,
98 - y = 4y + 13
Collect like terms;
-4y - y = 13 - 98
-5y = -85
Divide both sides by-5;
y = 17
x = 98 - y
x = 98 - 17
x = 81
Therefore, the two numbers x and y are 81 and 17 respectively.

Corner Grocery charges $4.80 for 12 sodas. Max's Market charges $5.25 for 15 sodas.
Which store has the best unit price on sodas, and by how much?
Answer:
To do this, just do 12 divided by 4.80 = 2.5 dollars per can at Corner Grocery, and at Max's Market 15 divided by 5.25 = 2.85 per can. So the Corner Grocery has a better unit price by 35 cents.

What is an equation of the line that passes through the point (8,-8) and is perpendicular to the line 4x-3y=18
Answer:
Step-by-step explanation:
4x-3y=18
3y=4x-18
y=4/3x-6
By y=mx+c , Slope of line 4x-3y=18 is 4/3
Since the required line is perpendicular to the line 4x-3y=18 ,
slope of required line * Slope of line 4x-3y=18 = -1
slope of required line = -1/(4/3) = -3/4
Since the required line passes through (8,-8)
By point-slope form,
y-(-8)= -3/4(x-8)
y= -3/4x-2

7x = 28
x = 28/7
x = 4
Answer:
x = 4
Step-by-step explanation:
Step 1: Simplify both sides of the equation
2x +15 = 43 - 5x
2x +15 = 43 + - 5x
2x +15 = - 5x + 43
Step 2: Add 5x to both sides
2x + 15 + 5x= - 5x + 43 + 5x
7x +15 = 43
Step 3: Subtract 15 from both sides.
7x +15 -15 = 43 - 15
7x = 28
Step 4: Divide both sides by 7.
7x/7 = 28/7
