Answer:

a=5,b=10,c=15

1)(a+b)-5(c+a)

=(5+10)-5(15+5)

=(15)-5(20)

=15-5(20)

=10(20)

=200

2)(10×15)10(5×2)

=150×10×10

=15000

3)(a-b)+(a+b)

(5-10)+(10+5)

(-5)+15

-5+15

=10

4)(2ab-45)+a

=(2×5×10-45)+5

=(100-45)+5

=55+5

=60

andre [41]

Answer:

The distance from Gary's school to the BART station is 564 yards

Step-by-step explanation:

Let

x ----> the distance from Gary's school to the corner market

y ----> the distance from Gary's school to the BART station

we have

$x=47\ yd$

we know that

To find out the distance from Gary's school to the BART station, multiply the distance from Gary's school to the corner market by 12

so

$y=12x$

substitute the value of x

$y=12(47)=564\ yd$

therefore

The distance from Gary's school to the BART station is 564 yards
