Answer:
Joelle:155,Anita:270
Step-by-step explanation:
Hello, I think i can help you with this.
Step 1
define
Let
A, Anita's score
J, Joelle’s score
According to the question data
- their combined total score for one game was 425 points.in mathematics terms it is:
A+J=425,equation (1)
- Anita’s score was 40 less than twice Joelle’s: it means that you can take twice joelle's score and subtract 40 to obtain Anita's scor
2J-40=A,equation (2)
,
Step 2
find the values A and J
replace A from equation (2) into equation (1)
A+J=425
(2J-40)+J=425
solve for J
2J-40+J=425
3J=425+40
J=465/3
J=155
Now, put the value of J in equation (1) or equation (2) to find A
A+J=425
A+155=425
A=425-155
A=270
Hence, Joelle:155,Anita:270
Have a good day
It would be the last choice Joelle: 155, Anita: 270

let the numbers be x and y
x + y = 1600 ----*
12%x = 20%y
0.12x = 0.2y
y = <u>0</u><u>.</u><u>1</u><u>2</u><u>x</u>
0.2
y = 0.6x
substitute in * eqn
x + 0.6x = 1600
1.6x = 1600
x = 1000
then,
y = 0.6*1000
y = 600
the numbers are 1000 and 600
Answer:
4x² + 12x + 18
Step-by-step explanation:
This would be the trinomial.
Answer:
dadating din yan❤ hehehe
The First One
The Third One
The Forth One
The others result in a lower number than what they are supposed to be. The 3 correct ones end with the exact number of the equations solution number.
(4-4x)(x-3)
4x-12-(4x^2)+12x
(-4x^2)+16x-12=(pxq)(x)
