Answer:

468

Step-by-step explanation:

831-x would be the equation to find the amount of peanut butter cookies. You'd plug this into the equation to find the amount of cookies in relation to money meaning your equation is 1.5x+1.65(831-x)=1316.7. You then simplify and solve to find 468

elena55 [62]

Answer:

{ \rm{y =  - 3x + 5}}

Gradient = -3

• Parallel lines have the same gradient, therefore gradient, m is -3

{ \rm{y = mx + c}}

• At point (0, -4)

{ \rm{ - 4 = ( - 3 \times 0) + c}} \\  \\ { \rm{c =  - 4}}

y intercept is -4

{ \boxed{ \boxed{ \mathfrak{answer : }}{ \rm{\:  \: y =  - 3x - 4}}}}

16^5/4•16^1/4/(16^1/2)^2
Kazeer [188]

Answer:

The simplified expression is 16^-1/6

Step-by-step explanation:.

16^5/4•16^1 /4/ (16^1/2)^2

The dot means multiplication. The expression is rewritten as

16^5/4 × 16^1/4 / (16^1/2)^2

Recall the following rules of indices

1) y^a × y^b = y^(a+b)

2) (y^a)^b = y^ab

y^b/ y^a = y^(b-a)

Applying these rules of indices

16^5/4 × 16^1/4= 16^((5/4×1/4) = 16^((5/16)

(16^1/2)^2= 16^ 1/2×2 = 16^1 = 16

Therefore

16^5/4 × 16^1/4 / (16^1/2)^2

= 16^(5/16) /16

=16^(5/6) × 16^-1

= 16^ (5/6)-1

= 16^-1/6)

,The simplified expression is 16^-1/6
