Answer:

7 buses

Step-by-step explanation:

when doing a problem like this you have to divide the larger group of people by the smaller group

78 divided by 12 = 6.5

if u answered this multiplication problem correctly you would get 6.5 but u cannot put .5 people on a bus lol. so therefore u are not done yet... so u need to round up

here's a poem to help with ur rounding...

Find a place look next door

4 or less let it rest

5 or more raise the score!!!

so in conclusion your answer would be 7!

The common multiple for 1/2 1/4 1/6 1/3 and 1/5 would be 60:

2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60

52.) Five times a number is 45

Rom4ik [11]

52). 5x=45 Divide each side of the equation by 5.

53). -3x = 12 Divide each side by -3.

54). x/4 = 10    Multiply each side by 4 .

55). x/3 = -8    Multiply each side by 3 .

1). x -10 = 12 . Add 10 to each side.

3). x + 8 = 16    Subtract 8 from each side.

5). 5 + x = 6 Subtract 5 from each side.

7). x - 4 = 9    Add 4 to each side.

Thank you for the 5 points. The crust and warm water are delicious.

40 - 2 to the second power•9+17 can you please show me how you got this answer and tell me what it is please I will mark brainie

ollegr [7]

Use orders of operations.
$40 - {2}^{2} \times 9 + 17 \\ 40 - 4 \times 9 + 17 \\ 40 - 36 + 17 \\ 4 + 17 \\ = 21$

Answer:

52°: angles 4, 13, 18
128°: angles 1, 3, 14, 17
44°: angles 5, 12, 15
136°: angles 2, 6, 11, 16
84°: angles 7, 10
96°: angles 8, 9

Step-by-step explanation:

Where a transversal (t or u) crosses parallel lines (m and n), there are four angles formed at each intersection. Corresponding and vertical angles are congruent.

Angles in a linear pair are always supplementary. Of course, the angles interior to a triangle always total 180°. These facts let you find the relationships of all the angles in the figure.

Angle 13 corresponds to the given angle 52°, so has the same measure. Angles 4 and 18 are vertical angles with respect to those, so also have the same measure. Angles 1 and 3, 14 and 17 are supplementary to the ones just named, so all have measure 128°.

In the same way, angles on the other side of the figure can be found from the one marked 44°. Angles 5, 12, and 15 also have that measure; and angles 2, 6, 11, and 16 are supplementary, 136°. Angles 7 and 10 finish the triangle interior so that its sum is 180°. That means they are 180° -52° -44° = 84°. Of course, angles 8 and 9 are the supplement of that value, 96°.

In summary:
