4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5
Answer:
120 degrees.
Step-by-step explanation:
All the angles in a triangle add up to 180. You have two of the angles given:
50 degrees and 70 degrees
To find the third angle of the triangle (BAC), use the expression:
180 - (50 + 70)
180 - 120
60
So, the third angle in the triangle is 60 degrees. Looking at angle DAB, you can see that it forms a straight line with angle BAC. A straight line is 180 degrees. Since we know BAC is 60, and BAC + DAB = 180, by doing 180 - 60, you can see that angle DAB is 120 degrees.
Answer:
9. $2,860 per month
10. $660 per week
11. $94 per day <u><em>(not 100% sure on this one, not sure if its getting techinical with working 5 days a week)</em></u>
Step-by-step explanation:
9. $34,320 divide by number of months in a year (12)
10. $34,320 divide by number of weeks in a year (52)
11. $34,320 divide by number of days in a year (365)
First you convert the percentage into a decimal. 18% to 0.18, then you multiply that decimal to the price of the item being discounted and bam, you have your price.
