7x=21

divide both sides by 7 to get x by itself

7x/7= 21/7

cross out 7 and 7 , divide by 7

Multiplying positive numbers always comes out positive, no matter how many there are.  So you can forget about the positive ones.

Every two negative numbers in a multiplication produce a positive.
Another way to say that is:  If the number of negative ones is EVEN,
the answer is positive, and if it's ODD, the answer is negative.

That monster product of eight numbers in problem #12 will be negative,
because there are an odd amount of negative factors in it.

E is 3 more than d.<br> f is 5 less than d.<br> Write an expression for e in terms of d
Nataly_w [17]

Answer:

Part A:

We are given that E is 3 more than D. This means that to get the value of E, we will simply add 3 to the value of D

Therefore:

E = D + 3

Part B:

We are given that F is 5 less than D. This means that to get the value of F, we will simply subtract 5 from the value of D

Therefore:

F = D - 5

Part C:

To get the value of E-F, we will simply subtract the equation we obtained from part B from the equation we obtained from part A

Therefore:

E - F = (D+3) - (D-5)

E - F = D + 3 - D + 5

E - F = 8

Hope this helps :)

2/3 + 1/2 in simple form fractions

Try and find the common denominator which is 6 since 2×3 is 6 then once u get ur denominator u have to find the numerator which would be 4/6+3/6 And that would equal 7/6 and if you would u would keep it like that but if u would have to change it into a mixed fraction it would be 1 and 1/6
