Answer:
x=20
Step-by-step explanation:
3/5x+4=16
3/5x-4=16
3/5x=-4
3/5x=12
3/5x divided by 3/5 because 3/5 is being multiplied by x and you do the oposite
12 divided by 3/5
do kcr or kcf
to get your answer
1m 36 cm= 136 cm
136x80=1520
=£15.20
Answer:
y=5x+7
Step-by-step explanation:
y-y₁=m(x-x₁) will be our starting equation
Now input (-2, -3) and 5 as our slope because a parallel line has the same slope.
y-(-3)=5(x-(-2)) Input
y+3=5(x+2) Simplify
y+3=5x+10 Distribute 5 into the parenthesis
y=5x+7 Subtract 3 from both sides
The planes could be at different altitudes.
Step-by-step explanation:
using Pythagoras a²+b²=c²
13²+16²
169+256=425
square root of 425 is 20.6 which round to 21 miles
