Find two numbers if their sum is 6.1 and their difference is 1.6

Radda [10]

For this case, the first thing we must do is define variables:
x: unknown number (1)
y: unknown number (2)
We now write the equations that model the problem:
their sum is 6.1:
$x + y = 6.1
$
their difference is 1.6:
$x - y = 1.6
$
Solving the system we have:
We add both equations:
$x + x = 6.1 + 1.6

2x = 7.7

x = 7.7 / 2

x = 3.85$
Then, we look for the value of y using any of the equations:
$x - y = 1.6

y = x - 1.6

y = 3.85 - 1.6

y = 2.25$
Answer:
The numbers are:
$x = 3.85

y = 2.25$

Solve the system of equations. y = 6x - 27 y = 4x - 17

NeTakaya

Y=6x-27...........(1)
y=4x-17...........(2)

By comparison
6x-27=4x-17
=> 2x=10 => x=5
Substitute x=5 into (1)
y=6(5)-27=3
Check:
y=4(5)-17=3 as well.

The Markup percentage is mathematically given as

M=42%

<h3>What is Mark up percentage?</h3>

The markup % may be determined by dividing the gross profit of a unit (the difference between its sales price and the amount it cost to create or buy for resale) by the amount that unit originally cost. If a product sells for $12 but only costs the corporation $8 to produce it, the markup percentage for that product is 50%, which can be calculated as (12 - 8) divided by 8.

Generally, the equation for is Total cost price mathematically given as

TCP= Pay+insurance

Therefore

TCP=35.5*1.6

TCP=284/5

Generally, the equation for is Total selling price mathematically given as

TSP=89.99+7.99

TSP=97.98

In conclusion, Mark up percentage is

$M=\frac{SP-CP}{SP}*100\\\\$

$M= \frac {97.98 - (284/5) }{97.98} *100$

M=0.4202898551*100

M=42%

The skate Sports Store offers 4-wheel and 5-wheel inline skates. On display in the store are the left skates for 17 different st

beks73 [17]

There are 6 skates in store with 5 wheels.

<h3>What is Equation?</h3>

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Here, Let the number of 4 wheel skates in display be x

and the number of 5 wheel skates in display be y

Total number of skates = 17

Total number of wheel = 74

Now, according to question

x + y = 17 ................(i)

4x + 5y = 74 ..................(ii)

From equation (i), we get

x = 17 - y ................(iii)

put the value of y in equation (ii), we get

4(17 - y) + 5y = 74

68 - 4y + 5y = 74

y + 68 = 74

y = 6

Put the value of y in equation (iii), we get

x = 17 - 6

x = 11

Thus, there are 6 skates in store with 5 wheels.
