kirill [66]3 years ago

6 0

Answer:

Step-by-step explanation:

2p-3q=4

or p=4+3q/2

now putting the value in the second eq we get

3 x(4+3q/2)+2q=9

or 12+9q /2 +2q=9

or 12+9q+4q=18

or 13q=18-12

or q= 6/13

so p will be 4+18/13=70/13 divided by 2 so p=35/13

Gnesinka [82]

Answer:

Step-by-step explanation:

"8 kg of mixed nuts containing 26% peanuts"

weight of peanuts: 26% * 8 kg = 0.26 * 8 kg = 2.08 kg

"5 kg ... that contain 52% peanuts"

Total weight of peanuts: 2.08 kg + 2.6 kg = 4.68 kg

Total weight of mixed nuts: 8 kg + 5 kg

percent of peanuts: (4.68 kg)/(13 kg) * 100% = 36%
