1 mm = 0.1 cm
(a) 5 mm
5 × 0.1 = 0.5
Fraction :- 5/0.5
5 ÷ 0.5 =10
Decimal:- 10
(b) 8 mm
8 × 0.1 = 0.8
Fraction:- 8/0.8
8 ÷ 0.8 = 10
Decimal:- 10
Angie made an error because she used substitution incorrectly in step 3.
<h3>System of equation </h3>
7x + y =−12
7x + 4y = −6
subtract equation(i) from (ii) to eliminate x
Therefore,
3y = 6
y = 6 / 3
y = 2
Therefore,
7x + 2 = -12
subtract 2 from both sides of the equation
7x = -12 - 2
7x = - 14
x = - 14 / 7
x = -2
(-2, 2)
Therefore, Angie use substitution incorrectly in step 3.

55 miles is 290400 feet so you are driving at 290400 feet per hour now there are 60 minutes In an hours so divide
290400/60=4840
4840 feet per minute
there are 60 seconds in a minute so divide again
4840/60=80.67
80.67feet per second rounded
6 kilometers is the greatest,but arranging from greatest to least: 6km, 60m, 600 cm or 6000mm
60 meters = 60 meters * 1km/1000 meters = 0.06 km600 centimeters = 600 cm * 1m/100cm * 1km/1000m = 0.006 km6000 millimeters = 6000mm * 1m/1000mm * 1km/1000m = 0.006km
<span>thus arranging from greatest to least:6km, 60m, 600 cm or 6000mm</span>
