What happens when the two addends have opposite signs and the number with the larger magnitude (size) is positive?
zimovet [89]

Answer:

The smaller addend is subtracted from the bigger addend

Step-by-step explanation:

Represent the two numbers with a and b such that a > b

So, the mathematical representation will be

+a + (-b)

Open the bracket

+a -b

<em>This implies that the smaller addend (b) is subtracted from the bigger addend (b)</em>

<em></em>

<em>Take for instance; a = 6 and b = 4</em>

<em>This gives</em>

<em></em>+6 + (-4)<em></em>

<em></em>

<em>Open the bracket</em>

<em></em>= +6 - 4<em></em>

<em></em>= 2<em></em>

find to consecutivephone number such that five times the smaller number plus 3 times the greater number make 59 hint let the num
Scorpion4ik [409]

Answer:

x = 7 is the answer for the smaller number

7 + 1 = 8 is the answer for the larger number

Step-by-step explanation:

LET x and  x+1 be the two numbers here, as your hint suggests.

5x + 3(x+1) = 59

5x + 3x+3 = 59

8x = 59-3

8x = 56

/8      /8

--------------------------

x = 56/8 ---> x = 7

x = 7 is the answer for the smaller number

7 + 1 = 8 is the answer for the larger number

Check:

5 * 7 + 3 * 8 = 59

35 + 24 = 59

59 = 59 CORRECT
