Answer:
126.73
Step-by-step explanation:
5.03+13.7+108
5.03+13.7= 18.73
18.73 +108=
126.73
12/2=6.
6X0.5=3
so the scale drawing is 3 inches long
10/2=5
5X0.5=2.5
so the width of the scale drawing is 2.5 inches
3+3+2.5+2.5=11
Answer:
Step-by-step explanation:
If the equations are true, they can be solved simultaneously.
Consider 2x-10y=-1 as Eq1 and 5x+6y=4 as Eq2
Multiplying Eq1 with 3 and Eq2 with 5 we get,
6x-30y=-3 -- Eq3 and 25x+30y=20 -- Eq4
Adding Eq3 and Eq4,
31x=17 Therefore, x=17/31
Plugin x=17/31 in Eq3,
6(17/31)-30y=-3 --- y=13/62
Plug In values of x and y in 7x-4y we get,
7(17/31)-4(13/62) = 3
So the value of 7x-4y = 3.
Step-by-step explanation:
1kg=1000g
400kg=400*1000
=400000
Therefore 400kg =400000g
Answer:
I want to say 50 cars
Step-by-step explanation:
If i am correct, there are more cars than people overall:
tenants to cars
3:5
so when you have 30 tenants you can multiply the cars by ten because that is what you did on the other side.
