Step-by-step explanation:
La un supermarket sau vandut intro zi 32kg de banane si 86kg de portocale incasanduse 536 lei a doua zi sau vandut 96 kg de banane si 52kg de portocale incasanduse 784 lei cati lei costa un kg de banane dar de portocala
Answers
Answer:
the banana cost per kg is 6 and for orange it is 4
Step-by-step explanation:
The computation is shown below:
Let us assume the banana be x
And, the oranges be y
Now according to the question
There would be two equations
32x + 86y = 536.......(1)
96x + 52y = 784.........(2)
Now multiply by 3 in equation 1
96x + 258y = 1,608
96x + 52y = 784
258y - 52y = 1608 - 784
206y = 824
y = 4
And, the x would be
32x + 86(4) = 536
32x + 344 = 536
x = 6
Hence, the banana cost per kg is 6 and for orange it is 4

Answer:
x = 70°
Step-by-step explanation:
the interior angle which is supplemental to 140° is 40°
the sum of the interior angles of any triangle is 180°

180° = 40° + 2x
subtract 40° from each side of the equation:
2x = 140°
x = 70°

Answers
Answer:
784000J or 784KJ
Step-by-step explanation:
Kinetic energy (KE) can be represented with the formula
KE = 1/2(MV²)
where
M = Mass of object (Kg) =2000kg
V = velocity or speed of object in metre per second (m/s or ms^-1) = 28m/s
therefore
KE = 1/2(mv²) becomes
KE = (1/2) X 2000 X 28 X 28
KE = 784000Joules

Members of a baseball team raised $1479.25 to go to a tournament. They rented a bus for $800.50 and budgeted $45.25 per player for meals. Write and solve an equation which can be used to determine pp, the number of players the team can bring to the tournament.
Answers
Answer:
15 players
Step-by-step explanation:
First, you might want to exclude out how much it cost to rent a bus.
1479.25 - 800.50 = 678.75
After that, the remaining amount of money is how much money is spent altogether for the basketball player's meal, since each player had the same budget for the meal, it made the question easier.
678.75 ÷ 45.25 = 15
