Answer:
x = - 7
Step-by-step explanation:
Given that the terms are in AP , then
a₃ - a₂ = a₂ - a₁ , substitute values
3x + 4 - (2x - 1) = 2x - 1 - (2x + 1) ← distribute and simplify both sides
3x + 4 - 2x + 1 = 2x - 1 - 2x - 1
x + 5 = - 2 ( subtract 5 from both sides )
x = - 7
Answer:
12/12
Step-by-step explanation:
I would say simply perform the division already indicated.
(16 in)/(12 h) = 16/12 in/h = 4/3 in/h
__
Alternatively, divide the given rate by 1. The form 12/12 gives you the same thing as above:
(16 in)/(12 h)/(12/12) = (16/12) in/h = 4/3 in/h
Answer:
It would take 69 days for the sunflower to grow 6 feet. I know this because I found the unit rate by dividing 92 by 8 which equals 11.5. Since it is a proportional relationship all i had to do was times 11.5 by 6 to get the ratio 6 feet per 69 days.
Answer:
x = 4
Step-by-step explanation:
We assume that the given expessions represent the measures of the alternate interior angles, so are equal.
... (4x + 12)° = 7x°
... 12 = 3x . . . . . . . divide by degrees, subtract 4x
... 4 = x . . . . . . . . . divide by 3
_____
Then the angles are 7x° = 28° = (4x+12)°.
The first one is:
y = 5-7=-2
(5, -2)
second one:
4 = x + 3
x =4-3=1
(1,4)
