Answer:
6)-3
Step-by-step explanation:
6) y=mx+c
we need to rearrenge it.
c will go the other way
so mx=y-c
and then
move the m as it is multiplying will devide
so x=(y-c)÷m
and then put the values
x=(0.6-1.8)÷0.4
x= -3
7) A=(bh)÷2
same as we have to arrange
it is deviding so will multiply
and
bh=2A
multiplying so devide
b=(2A)÷h
so put values
b=(2(9.8))÷0.84
b=23.3333
two significant figures means 2 numbers after decimal
so
23.33
this is answer
:)
