22 + 17s < = 80....with s being the number of shirts
Answer:
Oslo
Step-by-step explanation: -12 is below -5. Therefore it is colder the further below on the temperature
The two equations given in the question are
x = y + 10
And
x = 2y + 3
Now let us substitute the value of x in the second equation with that of the first equation. We get
x = 2y + 3
y + 10 = 2y + 3
y - 2y = 3 - 10
- y = - 7
y = 7
Now putting the value of y in the first equation, we get
x = y + 10
= 7 + 10
= 17
So the value of x comes out to be 17 and the value of y comes out to be 7.
What is the value of x in the equation 3x-4y=65 when y=4?
Simple...plug n chug..
3x-4(4)=65
3x-16=65
Now, isolate the variable, x....
3x-16=65
+16 +16
3x=81
Now, divide,
x=27.
Thus, your answer.
