Answer:
628
Step-by-step explanation:
Deposit means money is going into the bank so add 129 onto 499
(b) writing a cheque means money is coming out of the bank so subtract 24 from your previous answer.
628 - 24 = 604
(c) again, this money is coming out so take 151 away from 604
(d) round 604 to the nearest hundred
(it's between 600 and 610 but which is it closest to?)
Answer:
B: Using x and y factor results in an expression of greater value than using x and y as terms.
Step-by-step explanation:
For her first expression, x and y are factors;
xy
For her second expression, x and y are written as terms;
x + y
For x and y are both negative integers, then;
-x * -y = xy ............... 1
-x + (-y) = - x - y
= - (x + y) .............. 2
Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.
Answer:
114 marbles.
Step-by-step explanation:
Let the number of red marbles be r
Let the number of black marbles be b
<u>Given the following data;</u>
Total number of marbles = 120
Translating the word problem into an algebraic equation, we have;
.......equation 1
........equation 2
Substituting the value of "r" into equation 2, we have;
b = 6 marbles.
To find the number of red marbles;
From equation 1;
Substituting the value of "b" into equation 1, we have;
<em>r = 114 marbles.</em>
<em>Therefore, there are 114 red marbles in the bag. </em>
