Answer:
The equations are:
10x + 9y = 122
x + y = 13
Step-by-step explanation:
Given Jose makes 10$ per hour washing cars and 9$ per hour walking dogs.
Also, it is given that he had worked for 13 hours total making 122$.
Let us assume the number of hours he spent on washing cars = 'x'.
Let us assume the number of hours he spent on walking dogs = 'y'.
Since, the total number of hours is 13, we can write:
x + y = 13 . . . eqn(1)
And since he has made 122$ in total, we will have:
10x + 9y = 122 . . .eqn(2)
'10x' represents the total money earned by washing cars and '9y' represents the total hours spent on walking dogs.
Hence, Eqn (1) and Eqn(2) is the answer.
Solving them will give: x = 5 and b = 8.
10 and 15 dear^^ 5(15) + 3(15) =28
Answer:
Option B.
Step-by-step explanation:
we know that
A <u>r</u><u><em>igid transformation</em></u> is a transformation that does not alter the size or shape of a figure.
The translation is a rigid transformation that produce congruent figures
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
therefore
The squares are congruent because translations are rigid transformations that preserve the length of the sides of the square
Answer: 2.5
Step-by-step explanation:
You have the following fraction given in the problem above:
5/2
Where the number on the top is called the numerator and the number on the bottom is called denominator.
To solve this exercise you must divide the numerator 5 by the denominator 2.
Therefore, you obtain the folloowing result:
5/2=2.5
The inequality you require is
The number of bottles left at the end of each day is 48 - 3x. So it is:-
48 - 3x < 10
Solving the inequality to find the last part of question:-
-3x < 10 - 48
-3x < -38
x > 38/3 = 12 2/3
So answer is 13 days.
