Answer:

Y =-7 and X -3

Solution:

4x-2y=2

2(2x-y)=2⋅1

2x-y=1

and y+4=x

∴y-x=-4

Suppose,

2x-y=1→(1)

and -x+y=-4→(2)

Taking equation (1), we have

2x-y=1

⇒y=2x-1→(3)

Putting y=2x-1 in equation (2), we get

-x+y=-4

-x+(2x-1)=-4

⇒-x+2x-1=-4

⇒x-1=-4

⇒x=-4+1

⇒x=-3

⇒x=-3→(4)

Now, Putting x=-3 in equation (3), we get

y=2x-1

⇒y=2(-3)-1

⇒y=-6-1

⇒y=-7

∴y=-7andx=-3

Dana buys dress shirts from a clothing manufacturer for s dollars each, and then sells the dress shirts in her retail clothing s

nydimaria [60]

Answer:

Consider the complete question is,

Dana buys dress shirts from a clothing manufacturer for s dollars each, and then sells the dress in her retail clothing store at a 35% markup

a. Write the markup as a decimal

b. write an expression for the retail price

c. What is the retail price of a dress shirt that Dana purchased for 32.00

d. How much was added to the original price of the dress shirt?

Reference : brainly.com/question/2202598

Solution :

Here, s represents the price of each dress shirt,

a. Since, markup percentage = 35%,

Thus, the markup in each shirt = 35% of price of each dress shirt

= 35% of s

$=\frac{35s}{100}$

= 0.35s

b. Retail price = original price + markup

= s + 0.35s

= 1.35s

c. if s = 32,

Retail price = 1.35(32) = 43.2

d. The added amount in original price = Retail price - original price

= 43.2 - 32

= 11.2

Answer:

8 cookies left to be baked

Step-by-step explanation:

Len

Len bakes 1/3 of 30 cookies

To find 1/3 of 30, divide 30 by 3 then multiply by 1:

$\implies \frac{30}{3} \times1=10 \times 1=10$

Therefore, Len bakes 10 cookies

Sallesh

Sallesh bakes 2/5 of 30 cookies

To find 2/5 of 30, divide 30 by 5 then multiply by 2:

$\implies \frac{30}{5} \times2=6 \times 2=12$

Therefore, Sallesh bakes 12 cookies

Cookies left to bake

To calculate how many cookies are left to bake, subtract the found number of cookies Len and Sallesh have baked from 30:

30 - 10 - 12 = 8

So there are 8 cookies left to be baked.

the sum of two numbers is 70. the larger number is five less than twice the smaller number . what are the two numbers

earnstyle [38]

X+y=70
x=2y-5
x=larger number
y=smaller number
now plug in the value of x to only have one variable in the equation...
Way to solve for y:
(2y-5)+y=70
3y-5=70
add 5 on both sides...
3y=75
divide by 3 on both sides
y=25
1st way to solve for x:
now plug in y in the original equation...
x+25=70
subtract 25 on both sides...
x=45
2nd way to solve for x:
plug in y for the second equation...
x=25(2)-5
x=50-5
x=45
answer: the two numbers are 45 and 25.
