Answer:
Step-by-step explanation:
7). Since, ∠4 and ∠5 are the linear pair of angles,
m∠4 + m∠5 = 180° [Supplementary angles]
72° + m∠5 = 180°
m∠5 = 180° - 72°
m∠5 = 108°
8). Since, ∠6 and ∠7 are the vertically opposite angles,
Therefore, ∠6 ≅ ∠7
m∠6 = m∠7
3x + 94 = 9x - 38
9x - 3x = 94 + 38
6x = 132
x = 22
m∠6 = 3(22) + 94 = 160°
m∠7 = 9(22) - 38 = 160°
9). Since, ∠2 and ∠3 are the linear pair of angles, both the angles will be supplementary.
m∠2 + m∠3 = 180°
(13x + 54) + (2x + 36) = 180°
15x + 90 = 180°
15x = 90
x = 6
m∠2 = 13(6) + 54 = 132°
m∠3 = 2(6) + 36 = 48°
Answer:
84°
Step-by-step explanation:
the total angle in a straight line sum up to 180°
Answer:
x=-8 then x times y coulum = x coulum answer same for if y=-9 then times x coulum =y coulum answers if y=x+5 solve for x be making y=0
Step-by-step explanation:
Start by piking the equations you want to use and put them on the lines below the box the take and put that into a table with that if it’s a x then you start with the y coulum and put -2,-1,0,1,2 ok then from their if you know what x is you times it by the y coulum and contiue to do that with all the x integers this is the same for the y integers except it’s switched. If you still don’t understand I suggest asking your teacher for help and be honest with them that you didn’t understand it.
To find this answer, first subtract 1,500 from the amount your class raises (16, 600) so you are just left with the 'leftover' money for students to board.
16600-1500= 15100.
Then, divide 15100 into 367 to find out how many can go.
15100/367= 41.1444. Round down to 41.
41 students can attend, and there will be a bit of leftover money. (if you want to figure out how much is left over, multiply 41 by 367, and then subtract 15100 by the product)
