Answer:

9 first class tickets and 8 coach tickets

Step-by-step explanation:

c + f = 17......c = 17 - f

270c + 1140f = 12,420

270(17 - f) + 1140f = 12,420

4590 - 270f + 1140f = 12,420

-270f + 1140f = 12,420 - 4590

870f = 7830

f = 7830 / 870

f = 9 <==== 9 first class tickets

c + f = 17

c + 9 = 17

c = 17 - 9

c = 8 <==== 8 coach tickets

Can someone help me with these both
Anna [14]
Hello,
so all you have to do is match the abbreviations to the triangles. The abbreviations stand for what is the SAME in both triangles, denoted by similar markings on equal sides and angles.

Abbreviations:
SSS = Side-Side-Side
SAS = Side-Angle-Side
ASA = Angle-Side-Angle
AAS = Angle-Angle-Side
HL = Hypotenuse-Leg

* Note - the angle side angle must go around the triangle in that order. ASA has the side BETWEEN the congruent angles.. SSA does NOT work.

(9.) ASA
(10.) AAS
(11.) SSS
(12.) No way to tell if congruent. (only 3 angles no side)
(13.) ASA
(14.) SAS
(15.) HL

5y-30=-5y+30 and also can you show the steps :}
KatRina [158]

5y-30=-5y+30

add 30 to both sides

5y = -5y+60

add 5y to both sides

10y = 60

divide both sides by 10

y = 6

<em>hope this helps!</em>

Brad earns $12.75/hr and works 40 hours a week. What is his gross annual income?
professor190 [17]

Answer:

Gross Annual Income:  $26,520

Step-by-step explanation:

Gross annual income is the amount of money made without any taxes or deductions subtracted from the total.  If Brad earns $12.75 per hour and works 40 hours per week, we can first find his weekly income by multiplying the rate by the number of hours per week:

$12.75 x 40 = $510.00

Since Brad earns $510 per week and there are 52 weeks in one year, we can find his gross annual income again by multiply the weekly rate ($510) by the number of weeks in a year (52):

$510 x 52 = $26,520
