Answer:
of the cake
Step-by-step explanation:
add and
to see the total amount of cake eaten.
a. find the common denominator: 8 x 3 = 24 and 6 x 4 = 24
b. multiply accordingly to get the correct numerator: +
c. add: +
=
subtract found value from total to find left over cake.
a. 24 - 7 = 14
simplify.
a. =
You are left with of the cake.
Answer:
See explanation
Step-by-step explanation:
Given the function f(x) for which
If you want to plot the corresponding points for the inverse of the function f(x), change into
:
switch x and y
and then change into
You get
Now plot these points on the coordinate plane (see attached diagram).
Using a system of equations, it is found that Peter had $48 at first.
<h3>What is a system of equations?</h3>A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
The ratio of peters money to henrys money is 4 : 3, hence:
After Peter spent $12, they had the same amount, hence:
y = x - 12.
Then, replacing in the ratio:
4(x - 12) = 3x
x = 48.
