Answer:
Step-by-step explanation:
In this particular case we have the following system of equations:
y
=
−
3
x
+
4
[
E

.
1
]
x
+
4
y
=

.
2
]
Substituting
[

in
[
E
q
.
2
]
:
x
+
4
(

)
=

6
Applying the distributive property on the left side:
x

Simplifying
:

x
=

Solving for
y
:
x
=

Substituting
x
=

in
[

Therefore
, the solutions are
x

and
y
=

For this case, the first thing we must do is define variables.
We have then:
x: number of baseballs
y: total amount
We know that each baseball costs $ m.
We also know that Robert has spent $ b.
Therefore, the expression that models the problem is given by:
Answer:
The following expression represents the total amount Robert will spend after buying x baseballs:
a full revolution of a circle is 18.84 cm
Full revolution is the circumference of the circle
we are given with circumference of the circle 18.84 cm
We need to find the diameter of the circle
Formula for the circumference of the circle is =
Where d is the diameter of circle
we assume the value of pi as 3.14
the circumference of the circle is =
18.84 = 3.14 * d
To isolate 'd' we divide both sides by 3.14
d = 6
the diameter of the circle is 6 cm
