multiply 300 by 7 and then you should be able to finish the equation
Answer:
For Example: Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.
Step-by-step explanation:
To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:
a2 b
( )2 ( )
(–2)2 (3)
(4)(3)
12
Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.
By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.
Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.
In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:
(–2) – (–4)(4)
–2 – (–16)
–2 + 16
16 – 2

ANSWER
We can divide in to two rectangles as in the attachment.
We then find the area of each rectangle and add together.
The area of the bigger rectangle is
The area of the smaller rectangle i
Hence the area of the figure is

Answer:
150 hombres juegan baloncesto.
Step-by-step explanation:
En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.
Paso 1
Encontramos el número de estudiantes que son mujeres
= 1/3 × 315
= 105 mujeres.
Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:
= 315 - 105 mujeres
= 210 hombres
Paso 2
2/7 de los hombres juegan fútbol y el resto baloncesto.
Esto significa que 2/7 de 210 hombres juegan al fútbol
= 2/7 × 210 hombres
= 60 hombres
Por tanto, 60 hombres juegan al fútbol.
Paso 3
También se nos dice que el resto juega al baloncesto.
El número de hombres que juegan baloncesto se calcula como:
210 - 60
= 150 hombres.
Por tanto, 150 hombres juegan baloncesto.
