Answer:

7 x (-9)

Step-by-step explanation:

7 x (-9) = -63

-3 x (-5) = 15

-2 x (-1) = 2

6 x 6 = 36

Can you multiply it all out? Yes. Did you need to? No. That was just to prove that the first choice is correct.

All you have to know to answer this is that:

positive * positive = positive; + * + = +

negative * negative = negative; - * - = +

positive * negative (or negative * positive; remember that the order of the numbers you're multiplying does not matter) = negative; + * - = - or - * + = -

Or if you learn better in words:

If two factors have the same sign, the answer is positive.

If two factors have different signs, like if one is positive and the other is negative, then the answer is negative.

Answer:

GH = 4

Step-by-step explanation:

Since G is between F and H then

FG + GH = FH , that is

8 + GH = 12 ( subtract 8 from both sides )

GH = 4

There is a competition in the cinema to win free tickets. You must guess the ages of the four employees. Here are the clues: - W

Answer:

Kirk is 28 years old, Brian is 36 years old, Matt is 18 years old, and the manager is 24 years old.

Step-by-step explanation:

Let $k$ be Kirk's age.

Let $b$ be Brian's age.

Let $m$ be Matt's age.

Let $m_{1}$ be the boss/manager's age.

From the information given, we can set up 4 equations:

$k+b+m+m_{1}=106$

$k=2(m_{1}-10)$

$b=2m_{1}-12$

$m=\frac{1}{2}m_{1}+6$

Rewrite the first equation, substituting $k$ , $b$ , and $m$ in terms of $m_{1}$ to get:

$2(m_{1}-10)+(2m_{1}-12)+(\frac{1}{2}m_{1}+6)+m_{1}=106$

Open up the parentheses using the distributive property (which is $a(b-c)=ab-ac$ ) and combine like terms to get:

$5.5m_{1}-26=106$

Add 26 to both sides to reach:

$5.5m_{1}=132$

Thus, $m_{1}=24$ . Substitute $24$ for $m_{1}$ in the second, third, and fourth original equations to find that $k=28$ , $b=36$ , and $m=18$ . Therefore, Kirk is 28 years old, Brian is 36 years old, Matt is 18 years old, and the manager is 24 years old. To check, you can add up all of the ages to get 106.
