Answer:
Step-by-step explanation:
87+95+76+88+x/5=85
346+x=85x5
x=425-346
x=79
Answer:
45 and 36
Step-by-step explanation:
For this case we have the following variables:
x: Quantity of orange picks
y: Quantity of green picks
According to the statement, we have the following proportion:
, that is:
If there are 21 picks, then:
So, we have two equations with two unknowns:
----> (1)
----> (2)
From (2):
Substituting x in (1):
Substituting in (2) and clearing x, we have:
So, there are 6 orange picks
Answer:
6 orange picks
Answer:
-4(5x - 9) + 6(2x + 5)
multiplication of:
(-).(-) = +
(-).(+) = -
(+).(-) = -
(+).(+) = +
-4(5x) -4(- 9) + 6(2x + 5)
(-)(+)4(5x) (-)(-)4(9) (+)(+) 6(2x) (+)(+)6( 5)
-20x + 36 + 12x + 30
-20x + 12x + 36 + 30
-8x + 66
Step-by-step explanation:
Q1: y = -3/2x +1
Q2: The graph changes vertically from -1 to 3 (4 units) at the same time it changes horizontally from -4 to 1/2 (4.5 units). The rate of change is 4/4.5 = 8/9 ≈ 0.8889. The closest answer selection is 9/10.
Q3: x=-2
Q4: The graph changes vertically by -4 at the same time it changes horizontally by +1. The slope is 4/-1 = -4. The y-intercept is +1, so the equation is
.. y = -4x +1
Q5: After the same pattern as above,
.. y = 5/2*x +5
