Y = 5x - 8 y = 4x - 7

Mathematics
1 answer:
stealth61 [152]3 years ago
8 0

ANSWER

(1,-3)

EXPLANATION

The given equations are:

y = 5x - 8

y = 4x - 7

We equate the two equations to get:

5x - 8=4x - 7

Group similar terms:

5x - 4x=-7+8

Simplify bottom sides

x=1

Put x=-15 into the first equation:

y=5(1)-8

y=-3

(1,-3)

The solution is (1,-3)

nevsk [136]

Answer:

look its really simple like if there is written the father age is two times than its son and its is also said sum of their age becomes 25 then

Step-by-step explanation:

solution,

let father and son age be x and y

2x =y ---------------(i)

x+y=25----------------(ii)

now,

putting the value of y in equation two we get,

x+(2x)=25

3x=25

x=25/3

x=8 yrs ( using round off)

again,

2x = y

2×8=y

16=y

therefore, father age is 16 and son age is 8

A two digits number is 21 times the difference and 350% of the product of its digit. Find the quotient of the digit of number​
Juliette [100K]
The number is 63, so the quotient is 2.

Two digit numbers divisible by 21:
21, 42, 63, 84

21: 2-1 = 1 * 3.5 = 3.5
3.5*2*1 = 7 but 7 does not equal 21

42: 4-2 = 2 * 3.5 = 7
3.5*4*2 = 28 does not equal 42

63: 6-3 = 3*3.5 = 13.5
3.5*6*3 = 63 :)

Check:
21(6-3)=21(3)= 63 :)
3.5(6)(3) = 21(3) = 63 :)

63: 6/3 = 2
