Im from k12
Step-by-step explanation:
Let
x--------> the amount in dollars that Luis make last week
we know that
------> equation that represent the situation
solve for x
Divide by both sides
therefore
the answer is
Answer:
He made $90 last week
Step-by-step explanation:
Since we are told that Louis made 80% of what he made last week and since Louise made $72 this week, to get how much he made this week, we will follow the step below:
let x be the amount he made last week
80% of x = $72
80% × x = $72
= $72
the fraction 80x/100 can be reduced to 4x/5. Hence;
= $72
Multiply both-side of the equation by 5
x 5 = $72 x 5
4x =360
Divide both-side of the equation by 4 to get the value of x
On the left-hand side of the equation 4 will cancel-out 4 while on the right-hand side of the equation 360 will be divided by 4
x = $90
Therefore he made $90 last week
The equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.
The given phrase is "nine less than six times a number is -15."
Let the unknown number be x.
Here, six times a number = 6x
The product is less than 9, that is
6x-9
Nine less than six times a number is -15, so the equation is
6x-9=-15
Now, the solution is
6x=-15+9
6x=-6
x=-6/6
x=-1
Therefore, the equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.

Hello!
6 - 9 × y = -15
When "less than" is used you switch the number before it the number after it. While it seems like it would be 9 -6, its actually 6-9
6 - 9 is -3, you can multiply 3 by 5, to get 15. So your answer would be 5
Hope this helps!
