Answer:

3 AND 5

Step-by-step explanation:

LET THE TWO NUMBERS BE X AND Y

THEN

X + Y = 8 …….1

X – Y = 2 …… 2

WE SOLVE SIMULTANOUSLY  

SUBTRACTNG EQATION 2 FROM 1

X – X  + Y – (-Y) = 8 – 2

Y + Y = 6

2Y = 6

DIVIDING EACH TERM BY 2

2Y/2 = 6/2

Y = 3

THEN PUTTING Y = 3 IN EQUATION 1

X + 3 = 8

X = 8 – 3

X = 5

I only need help on number 6 plzzzz help
Gennadij [26K]
That question is asking for the time so your answer will specifically be in hours. And I'm not sure if you divide or you multiply but I'm pretty sure the correct answer is dividing because tomorrow so cancel the miles they will be left with hours. I don't know if that makes sense to you but it kind of makes sense to me somehow.

Lincoln middle school plans to collect more than 2,000 cans of food in a food drive. So far, 668 cans have been collected. WRITE
AURORKA [14]
Let x be the unknown number.

7x + 668 < 2000     => 7x plus 668 is less than 2000

where:
7x => x represents the number of cans to be collected in 7 days
668 is the number of cans already collected.
2000 is the target number of cans.

7x  +  668    <    2000
 <u>       - 668           -668</u>
7x                <   1332
<u>÷7                        ÷7</u>
x                  <    190.30
or
x < 190

To check:

7x + 668 < 2000
7(190) + 668 < 2000
1330 + 668 < 2000
1998 < 2000
