The sum of three consecutive multiples of 4 is 444. Find the multiples.<br> PLEASE ANS FAST PLS
SOVA2 [1]

Answer:

144,148,152

Step-by-step explanation:

Here we will have, 4x + 4(x+1) + 4(x+2) = 444

=> x + (x+1) + (x+2) = 111 (dividing both sides by 4)

=>x + x+1 + x+2 =111

=> 3x + 3 = 111

=> 3x = 108

=> x = 36.

So, the three desired numbers 4x, 4(x+1) and 4(x+2) are,

4*36, 4*(36+1) and 4*(36+2)

That means the numbers are, 144, 148 and 152.

1.1888 (8 goes on forever) seconds to travel from the satellite to Earth.

Step-by-step explanation:

It is traveling at 3 x 108 m/s and needs to travel 3.6 x 107 m. 3 x 108=324 and 3.6 x 107=385.2 so 324 m/s for 385.2 m. 385.2/325=1.1888.
