Answer:

a) $\boxed{\boxed{\sf p = 18 }}$

b) $\boxed{\boxed{\sf t = 3 }}$

c) $\boxed{\boxed{\sf p = 6 / by /5 }}$

Explanation -

a) 2/3 p + 10 = r

Value of r = 22 (given)

2/3 p + 10 = 22

2/3 p = 22- 10

2/3 p = 12

p = 12 × 3 /2

p = 6 × 3

p=18

b) (-17) + 5k = t

value of k = 4 (given)

(-17) +5 (4) = t

(-17) + 20 = t

3 = t

c) 0 = 5p - 3b

b= 2 (given)

0 = 5p - 3(2)

0 = 5p - 6

6 = 5p

6/5 = p

Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each. He handed out 2/3 of the cho

Answer:

Rasheed bought 9 packages of chocolates bar.

Step-by-step explanation:

Let C be the number of packages of chocolate bars.

Let T be the number of packages of toffee bars.

Rasheed handed out 2/3 of 2C of the chocolate bars and 3/5 of 2T of the toffee bars.

(1) Rasheed bought 1 fewer package of chocolate bars than toffee bars.

Equation becomes:

$C=T-1$ .....(1)

(2) Rasheed handed out the same number of each kind of candy bar .

Equation becomes:

$\frac{2}{3}\times 2C =\frac{3}{5}\times 2T$

=> $\frac{4C}{3} =\frac{6T}{5}$

=> $20C=18T$

=> $20C-18T=0$

Taking out 2 common, we get

$10C-9T=0$ ......(2)

Substituting $C=T-1$ in (2)

$10(T-1)-9T=0$

=> $10T-10-9T=0$

=> $T-10=0$

T = 10

As $C=T-1$

$C=10-1$

C = 9

Therefore, Rasheed bought 9 packages of chocolates bar.
