Finding two numbers

Mathematics
1 answer:
kramer2 years ago
4 0

Answer:

the larger number is 39 and the smaller is 35

Step-by-step explanation:

let the larger number be x and the smaller number be y

the larger number is 4 more than the smaller : x = y+ 4

the sum of the numbers is 74 : x+y = 74

knowing that x= y+4; (y+4)+y = 74

y+4+y=74

collect like terms : y+y=74-4

2y=70

y=70/2 ; y=35

substitute y=35 into (x=y+4)

X=35+4, x=39

WILL GIVE BRAINLIEST! Find the equation of a line that passes through (-5,-2) and the intersection of the lines x+3y=0 and 4x-4y
Verdich [7]

Answer:

y + 2 = -0.069(x-+5)

Step-by-step explanation:

SInce the two lines intersects, we will equate it

Multiply x + 3y = 0 by 4;

4x + 12y = 0

4x-4y-13 = 0,

Subtracts both

12y +4y + 13 = 0

16y = 13

y = 13/16

get x;

x + 3(13/16) = 0

x = -39/16

The point of intersection is (0.8, -2.4) and (-5,-2)

Get the equation;

m = y2-y1/x2-x1

m = -2+2.4/-5-0.8

m = 0.4/-5.8

m = -0.069

Get the equation;

y - y0 = m(x-x0)

y - (-2)= -0.069(x-(-5))

y + 2 = -0.069(x-+5)

A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain p
k0ka [10]

Given,

CP of cosmetics = Rs 360 per dozen

SP of a pair of cosmetics = Rs 80

We need to find the profit percentage.

Solution,

We know that,

1 dozen = 12 items

CP of 1 cosmetic = 360/12 = Rs 30

SP of 1 cosmetic = 80/2 = Rs 40

Profit = SP-CP

= Rs 40 - Rs 30

= Rs 10

Profit percentage is given by :

\%=\dfrac{profit}{CP}\times 100\\\\=\dfrac{10}{30}\times 100\\\\=33.34\%

So, the profit percentage is 33.34%.

(7/22) (44)=2r pls help
patriot [66]

Answer:r=7/7744

move all terms to the left:

(7/22)(44)-(2r)=0

add all the numbers together, and all the variables

-2r+(+7/22)44=0

multiply parentheses

-2r+7/22*44=0

multiply all the terms by the denominator

-2r*22*44+7=0

multiply elements

-1936r*4+7=0

multiply elements

-7744r+7=0

move all terms containing r to the left, all other terms to the right

-7744r=-7

r=-7/-7744
