Mark invests $4200 in two different accounts. The first account paid 3 %, the second account paid 7 % in interest. At the end of

nexus9112 [7]

Answer:

3% interest account = $2,700

7% interest account = $1,500

Step-by-step explanation:

We have to use equation to find the answer. Again, we are using simple interest to find how much is in each account.

We know, Interest = Capital x Interest rate x year

Let,

3% interest account = X

7% interest account = Y

According to the question,

X*0.03*1 + Y*0.07*1 = 186 ................. (i)

Again, X + Y = 4200 .................. (ii)

From equation (Ii), we get,

or X = 4,200 - Y ...................... (iii)

Putting the value of X in equation (i), we can get,

(4,200 - Y)*0.03*1 + Y*0.07*1 = 186

or, 126 - 0.03Y + 0.07Y = 186

or, 0.04Y = 186-126

or, 0.04Y = 60

or, Y = 1,500

Putting Y = 1,500 in equation (iii), we get

X = 4,200 - 1,500

X = 2,700

Therefore, 3% account had $2,700 balance

7% account had $1,500 balance.

Answer:

6.) 13 > c; open; left

7.) -9 < s; open; right

8.) 16 $\geq$ j; closed; left

9.) -16 $\leq$ z; closed; right

10.) 18 < w; open; right

Explanation:

Open (exclusive) whenever the sign is > and <. Closed (inclusive) whenever the sign is $\geq$ and $\leq$ . Goes to the left if the letter has the less than(#>c, c<#) or the less than and equal to(# $\geq$ c, c $\leq$ #) sign points towards it. Goes to the right if the letter has the greater than(#<c, c>#) or the greater than and equal to(# $\leq$ c, c $\geq$ #) sign points towards it. For the first part of the the questions just move all of the numbers to one side and the variables to the other.
