Jj sell tablets at a store. He earns $180 a week plus$15 for ever tablet he sells. Jj earns $315 last week. Write a equation tha
NeTakaya
So Jj earns a flat rate of 180 per week and an extra 15 per tablet he has sold
so what we need to do is subtract his flat rate(180) from his total(315)
 315
-180
____
135 So now we know how much money Jj has earned from selling tablets. But we still need to create an equation and find out how many he has sold.
So we know he get $15 per tablet so 135÷15=9
now we know he has sold 9 tablets
Bu what is our Equation?
well, what were the steps?
TP = total pay
FR= Flat rate
C= Computer profit
PPC= price per computer
#C = number of computers

#C = TP-FR=C C÷PPC=#C
can we simplify this further?
#C = C÷PPC
lets do this:
#C= x
C= y
PPC= z 
So:              (X = Y÷Z)

(6,-3) and (x,-29); slope=-3
Sidana [21]

Answer:

x=44/3

Step-by-step explanation:


slope = (y2-y1)/(x2-x1)

substitute what we know

-3 = (-29--3)/(x-6)

simplify

-3 =(-29+3)/(x-6)

multiply each side by (x-6)

-3(x-6) = (-29+3)/(x-6) * (x-6)

the (x-6)'s on the right cancel

-3(x-6) = (-29+3)

distribute

-3x*-3*-6 = -29+3

-3x+18 = -26

subtract 18 from each side

-3x = -44

divide by -3

x = -44/-3

x=44/3

Which ratio would help find the distance the person is from the flag pole ¨X¨ if the angle is elevation of 30 degrees.
WINSTONCH [101]

Answer:

There are three major trignometric ratios in mathematics and they are:

sine(sin), cosine(cos) and tangent(tan). A popular acronym is used in recalling the formula for each ratio and it is: SOH-CAH-TOA.

Sine(x) = Opp/Hyp

Cosine(x) = Adj/Hyp

Tangent(x) = Opp/Adj

Now, the Hyp is the hypothenus of the triangle and it is the side opposite to angle 90. The opposite and adjacent is kind of relative depending on the angle been considered. For this case, we are considering angle 30 which the opposite side is 60 and the remaining side becomes the adjacent

Step-by-step explanation:

tan 30 = 60/x
