(4,-1). 4x+3y=13. You do 4(4)+3(-1)=13. hope that helps.
Answer:
6x^2 - 19x + 10 is the answer
Step-by-step explanation:
Lets use the FOIL method to expand,
(2x - 5)(3x -2)
2x * 3x + 2x * -2 + -5 * 3x + -5 * -2
This is the expanded version of the expression above!
here is a better way of explaining it,
(2x - 5) is the first equation now lets split it up
now its 2x and -5!
now you just multiply 2x and -5 to the second equation (3x - 2)
makes sense?
Lets Simplify it,
2x * 3x + 2x * -2 + -5 * 3x + -5 * -2
6x^2 - 4x - 15x + 10
6x^2 - 19x + 10
(tip: DON'T FORGET SAY ^2 because there are 2x's in the (2x*3x) part!)
Now you just simplify!
So as a result the answer is,
6x^2 - 19x + 10
Hope this helps :)
Answer:
There are 320 students at Milton middle school.
Step-by-step explanation:
From the information provided, you can use a rule of three to find the total amount of students at Milton middle school as you know that there are 144 girls and they represent 45% of the students:
144 → 45%
x ← 100%
x=(144*100)/45
x=320
According to this, the answer is that there are 320 students at Milton middle school.
