The sum of two numbers is 153. The second is 3 more than 5 times the first. What are the two numbers?

Question

Write 7/10 as a decimal.

Find the slope and the y-intercept.
y = –5x + 3

List all the factors of 41.

Answer 1

x + y = 153
y = 3 + 5x
x + 3 + 5x = 153
6x = 150
x = 25

y = 3 + 5(25)
y = 128

7/10 = .7

y = -5x + 3
slope = -5
y-intercept: (0, 3)

41 is prime....no factors (except 1 and 41 of course) =)

Answer 2

Let x and y be the numbers
x+y=153 --- (1)
y=5x+3 --- (2)
using (2), (1) becomes x+5x+3=153
6x+3=153
6x=150
x=25
y=128
Check: 128 = 5(25)+3

2) 7/10 =0.7
3)y= -5x+3
slope = -5
y intercept is 3 (let x=0)
All factors of 41:
1 and no other number.

Answer 3

Question 1
Let numbers be x and y
x + y = 153
5x + 3 = y

x + 5x + 3 = 153
6x = 150
x = 25

25 + y = 153
y = 128

x = 25 , y = 128

Question 2
7 / 10 = 0 . 7

Question 3
y = - 5 x + 3
slope = - 5
y intercept is y = 3

Question 4
41 is a prime number and therefore has no factors other than 41 and 1

Answer 4

X + Y = 153
Y = 5X + 3
X + 5X + 3 = 153
6X = 150, X = 25

Y = 5X + 3, Y = 125 + 3 = 128

X = 25
Y = 128

7/10 as a decimal is 0.7

Slope = 5. Y Intercept = 3

Factors of 41 are 1 and 41

Answer 5

a + b = 153
b = 5a + 3

a + (5a + 3) = 153
6a = 153 - 3
6a = 150
a = 150 : 6
a = 25
b = 5(25) + 3 = 125 + 3 = 128
Solution: (25, 128)
><
7/10 = 0,7
><
For y = 0
-5x + 3 = 0
-5x = -3
x = 3/5
For x = 0
y = -5(0) +3
y = 3
(3/5 and 3)

Factors of 41 = 1 and 41

Answer 6

7/10=0.7
The slope is -5 and y intercept is 3.
41 is a prime number.Hence no factors
Oh my God! i have misssed the first question
Let one number be x
the second no. is 5x+3
therefore,5x+3+x=153
or,6x=153-3
or,6x=150
or,x=150/6=25
therefore the numbers are 25 and(25*5+3 or)128

Answer 7

1) x=25, y=128
2).70
3)m=-7 y int.=3/5 or .60
4)1 and 41

Answer 8

25 and 128 too easy
