Emma was about to finish grocery shopping when she noticed that cans of soup were on sale. Her total bill for groceries would be
Alinara [238K]

Answer:

3rd option: B(C)= 1.79C +86.03

Step-by-step explanation:

Total bill

= cost of cans(number of cans) +cost of other groceries

Let the cost of other groceries be G, and the cost of cans be X.

Given that number of cans= C,

Total bill= XC +G

If 2 cans were purchased,

2X+G= 89.61 -----(1)

If 5 cans were purchased,

5X +G= 94.98 -----(2)

(2) -(1):

(5X +G) -(2X +G)= 94.98 -89.61

5X +G -2x -G= 5.37

3X= 5.37

X= 5.37 ÷3 <em>(</em><em>÷</em><em>3</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

X= 1.79

Subst. X= 1.79 into (1):

2(1.79) +G= 89.61

3.58 +G= 89.61

G= 89.61 -3.58 <em>(</em><em>-3.58</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

G= 86.03 <em>(</em><em>simplify</em><em>)</em>

Total bill

= XC +G

= 1.79C +86.03

Thus, the function is B(C)= 1.79C +86.03.

The force newton(N),between two particles is inversely propotional to the square of the distance ,d m,between them.When particle
bonufazy [111]

Answer: 1.6\ N

Step-by-step explanation:

Given

The force between the two particles is inversely proportional to the distance between them

\Rightarrow F\propto \dfrac{1}{d^2}

When the distance is 2 m, the force is 10 N. For 5 m distance, it is

\Rightarrow \dfrac{10}{F_o}=\dfrac{5^2}{2^2}\\\\\Rightarrow F_o=10\times \dfrac{2^2}{5^2}\\\\\Rightarrow F_o=1.6\ N

Thus, the force between them is 1.6\ N

Solve for x: 2/7(x-2) = 4x
zheka24 [161]

Answer:

2/7(x-2)=4x

(2×x-2×2)/7 = 4x

(2x-4)/7 = 4x

2x-4×(1) = 4x × 7 ( Cross multiply)

2x-4 = 28

2x = 32

2x÷2 = 32÷2

x=16
