Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
Yesterday Hadi earned: $120
Today he will earn: $120*85% = $102
(You times the amount yesterday by 85% because you want to find the 15% less of 100% of the amount he's earned yesterday. Therefore, to find 15% less than yesterday you multiply it by 85% (100% - 15%) )
Tomorrow he will earn: $102*115% = $117.30
(Same thing here, however you are finding 15% more than 100% today. Therefore, you multiply the amount he earned today it by 115% (100% + 15%) )
To find the amount he earns for the three days you must add the amount earned of yesterday, today and tomorrow earned from the working above.
Therefore, Hadi expects to earn:
Yesterday + Today + Tomorrow = 120 + 102 + 117.30 = $339.3
Answer:
A and E
Step-by-step explanation:
When you re-arrange the expression, you still have the same answer.
2y = 3x + 14
(+2y) = (+3x) + (+14)
- rearranged -
(+3x) + (+2y) = (+14)
Please reconfirm with other students and correct me if I'm incorrect.
Edit: I am incorrect, but I don't know what I did wrong-
I think it’s 39 cuz we have to subtract it by 180(supplementary angles) plus the angle is an obtuse angle(meaning more than 0 but less than 90)
I'm not sure about the answer, but this is how I would do it, since 15% and $150 are the same based on the question. do let me know if it's right! :)
