7 spaces total
7 × 1cm = 7cm
6 box cars
6 × 7cm = 42cm
1 engine
1 × 12cm = 12cm
7cm + 42cm + 12 cm = 61cm
The train is 61cm long.
The answer for number 3 is 96.7 if you want the work shown I would recommend you to download the app Socratic and for number six you multiply.75x14 then also multiply.35x7 then add add up the answers which will be 12.95 then you subtract that from 15 the answer is $2.05
d) 10, -3
Hope I helped! ( Smiles )
Answer:
y = x+5
Step-by-step explanation:
First we find the slope
m = (y2-y1)/(x2-x1)
m = (7-3)/(2 - -2)
=(7-3)/(2+2)
= 4/4
= 1
The slope intercept form is
y = mx+b
y = x+b
Substitute a point in
7 = 2+b
Subtract 2 from each side
5 =b
y = x+5
-9-x/6=2=-1/6*x=11:-1/6. X=11÷(-1/6). Therefore, x=-66
