House , Computers , mobile , bottle , bags etc. are all made up of two or more three dimensional figures.
What are Three dimensional figures ?
Prisms and pyramids, as well as forms with curved surfaces, are examples of three-dimensional figures.
A prism is a three-dimensional object having two congruent parallel bases. Any polygon can be used for the bases, which are also two of the faces. Rectangles make up the rest of the faces.
The shape of a prism's base determines its name.
Everything in surrounding is made of many three dimensional figures

Solve using elimination
Multiply the first equation by 2 and the second by 5 so you can figure out x
10x-6y=-18
10x-25y=20
Subtract the two equations
19y=-28
y=-2
Plug y into the equation and you get x=-3
(-3, -2)
2. C Just model the equation
3. B Again, it's all about turning the word problem into equations
4. D. Use substitution and plug the x into the first equation.
5.
Multiply the whole first equation by 2.
You can see that because 4*2=8
8x+10y=16
Hope this helps.
example
2x+3y=2 is coincident with 4x+6=4 (multilied by 2)
so we have
4x+5y=8
next one was have
8x
we see that 4 times 2=8 so we just double the numbers
5 times 2=10
8 times 2=16
answer is 8x+10y=16
missing numbers are 10 and 16
subsitution meathod
absicalyy since you have x=y+2, then subsitue y+2 for x in the equaiton x+y=6 so
(y+2)+y=6
there fro the answer is D
d=desmond
g=george
d is 3 less than g
d=-3+g
d=g-3
combinded scores equals 187
d+g=187
the equations are
d=g-3 and d+g=187
the answer is B
child tikcet is 2 dollars so number of children times cost per child=cost
c times 2=cost=2c
adult tickets are same but differenc cost
6 times a=6a
so number of adults+number of kids=total number of people
c+a=38
cost of adults+cost of kids=total cost
2c+6a=148
the equations are
c+a=38 and 2c+6a=148
the answer is A
the solution is in the form (x,y)
so solv for x and y
5x-3y=-9
2x-5y=4
multily the first equation by -2 and the second equaiton by 5
-10x+6y=18
10x-25y=20
add them together
-10x+6y=18
10x-25y=20 +
0x-19y=38
-19y=38
divide both sides by -19
y=-2
subsitute
5x-3y=-9
5x-3(-2)=-9
5x+6=-9
subtract 6 from both sides
5x=-15
dvide by 5
x=-3
x=-3
y=-2
solution is
(-3,-2)
