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!

Simplify this expression HELP ASAP

Sergio039 [100]

Answer:

Step-by-step explanation:

Noting the following rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ = $\sqrt{ab}$

Given

( $\sqrt{2}$ + $\sqrt{3}$ )( $\sqrt{5}$ - $\sqrt{7}$ )

Each term in the second factor is multiplied by each term in the first factor

= $\sqrt{2}$ ( $\sqrt{5}$ - $\sqrt{7}$ ) + $\sqrt{3}$ ( $\sqrt{5}$ - $\sqrt{7}$ ) ← distribute parenthesis

= $\sqrt{10}$ - $\sqrt{14}$ + $\sqrt{15}$ - $\sqrt{21}$

System of equations-4× 7y=-8-5× 6y=1

Anton [14]

-4x + 7y = -8 . . . (1)
-5x + 6y = 1 . . . .(2)

(1) x 5 => -20x + 35y = -40 . . . (3)
(2) x 4 => -20x + 24y = 4 . . . . .(4)

(3) - (4) => 11y = -44 => y = -44/11 = -4
From (2), -5x + 6(-4) = 1 => -5x - 24 = 1 => -5x = 1 + 24 = 25 => x = 25/-5 = -5

Therefore, x = -5, y = -4
