Marcy needs to make 5 lb of a cashew/raisin mixture for a party. Her local grocery store sells raisins for $4.50/lb and cashews
Aloiza [94]

Answer:

Pounds of raisins = 1.5 lb

Pounds of cashew = 3.5 lb

Step-by-step explanation:

Let

Pounds of raisins = x

Pounds of cashew = y

x + y = 5 (1)

4.50x + 9.50y = 40 (2)

From (1)

x = 5 - y

Substitute x = 5 - y into

4.50x + 9.50y = 40

4.50(5 - y) + 9.50y = 40

22.50 - 4.50y + 9.50y = 40

- 4.50y + 9.50y = 40 - 22.50

5y = 17.5

y = 17.5 / 5

= 3.5

y = 3.5lb

Substitute y = 3.5 into

x + y = 5

x + 3.5 = 5

x = 5 - 3.5

= 1.5

x = 1.5lb

Pounds of raisins = 1.5 lb

Pounds of cashew = 3.5 lb

Iteru [2.4K]

Answer:

x = 50°

Step-by-step explanation:

sum of all angles of a quadrilateral is 360°

so, the other unknown angle be y

=》y + 40° + 110° + 80° = 360°

=》y + 230° = 360°

=》y = 360° - 230° = 130°

and the unknown angle + x = 180°

( because they for linear pair )

so, x + y = 180°

x + 130° = 180°

x = 180° - 130° = 50°

hence, x = 50°
