Answer:
79.5 + 5.5x = Y
Step-by-step explanation:
Sumo wrestler gained 5.5 kg per month
After 11 month, he weighed 140 kg.
Let x be his current weight.
Then x + 11(5.5) = 140
x = 140 - 60.5
x = 79.5
If Y is the weight of the wrestler after t months, then the linear equation would be:
79.5 + 5.5t = Y
Hello!
Find the slope using the slope formula:
We can use two points from the table and plug these into the equation. Use the points (5, 10) and (10, 20) to solve:
Simplify:
Answer:
It could be
Step-by-step explanation:
The calculation of sides of a rectangular triangle can be done by applying the Pythagorean theorem (the sum of the squares of the legs is equal to the square of the hypotenuse), both legs must form a right angle, and the value of the hypotenuse must be different from the legs. In the example what you give could be a value of one leg and the other of the hypotenuse.
Time A:
Para obter a média temos que somar todos os pontos e dividir pela quantidade de pontos, ou seja, 20 + 17+ 25+ 25+ 13+
25+ 12+ 25+25 +23= 210/10= 21
A média do time A é 21 pontos.
Time B:
O mesmo procedimento,
25+ 25+ 9+ 10+ 25+
11+25+ 15+10 + 25= 180/10= 18
A média do time B é 18 pontos.
