Step-by-step explanation:
5-55+41=15
50+41=15
91=15
94-15
=79
3r+55-61=7
3r=7+61-55
3r=7+6
3r=13
3r/3=13/3
r=13/3
r+5s-5=20
r+5s=20+5
r+5s=25
Answer:
---- equation 1
---- equation 2
A microscope costs S51 and a dissection kit costs S17
Step-by-step explanation:
Given
Represent microscope with M and Dissection kits with D
Cost:


Required
Represent as an equation:
To do this, we represent the equation in terms of cost and quantity
In terms of cost, we have:
---- equation 1
and
---- equation 2
Substitute 3D for M in equation 1



Divide both sides by 134


Substitute 17 for D in 


Hence:
<em>A microscope costs S51 and a dissection kit costs S17</em>
E. You will use the following....
Y2-Y1 divided by X2-X1
then get 14-5 divided by 4-1
as a result the answer is none of the above
