Consecutive integers are numbers one after the other on the number one (ie. 1,2,3,4,5 or 203,204,205).
times= multiplication
sum= addition
more than= addition
is= equal sign
x= first integer
x+2= second integer
x+3= third integer
3(x + (x + 2))= 5(x + 3) + 8
add inside parentheses
3(2x + 2)= 5(x + 3) + 8
multiply 3 and 5 by their parentheses
(3*2x) + (3*2)= (5*x) + (5*3) + 8
multiply in parentheses
6x + 6= 5x + 15 + 8
6x + 6= 5x + 23
subtract 5x from both sides
x + 6= 23
subtract 6 from both sides
x= 17 first integer
x + 1= 17 + 1= 18 second integer
x + 2= 17 + 2= 19 third integer
CHECK:
3(x + (x + 2))= 5(x + 3) + 8
3(17 + (17 + 2))= 5(17 + 3) + 8
3(17 + 19)= 5(20) + 8
3(36)= 100 + 8
108= 108
ANSWER: The three consecutive integers are 17, 18 and 19.
Hope this helps! :)
Answer:
(- 2, - 1 ), (2, 1 )
Step-by-step explanation:
Given the 2 equations
x - 2y = 0 → (1)
x² - y² = 3 → (2)
Rearrange (1) expressing x in terms of y by adding 2y to both sides
x = 2y → (3)
Substitute x = 2y into (2)
(2y)² - y² = 3, that is
4y² - y² = 3
3y² = 3 ( divide both sides by 3 )
y² = 1 ( take the square root of both sides )
y = ± 
= ± 1
Substitute these values into (3) for corresponding values of x
y = - 1 ⇒ x = 2(- 1) = - 2 ⇒ (- 2, - 1 )
y = 1 ⇒ x = 2(1) = 2 ⇒ (2, 1 )
Answer:
x > 3
Step-by-step explanation:
-7x < -21
Divide each side by -7, remembering to flip the inequality
-7x/-7 > -21/-7
x > 3
Answer:
The length of the missing side is: x = 15
Thus, option A) is the correct option.
Step-by-step explanation:
Let 'x' be the missing sides.
From the given triangle, it is clear that the segment cuts the sides into proportional ratios such 9 : 12 and x : 20 respectively.
Therefore,
9 : 12 = x : 20
9/12 = x/20
cross multiplication
12 × x = 20 × 9
12x = 180
divide both sides by 12
12x/12 = 180/12
x = 15
Therefore, the length of the missing side is: x = 15
Thus, option A) is the correct option.
