The equations would be
<span>Value: b + c = 19000
Interest: 0.07b + 0.09c = 1590
</span>0.07b + 0.09 (19,000 - b) = 1,590
0.07b + 1,710 - .09b = 1,590
<span>120 = .02b
</span>
B = 6,000
<span>C = 13,000
</span><span>
So the correct answer is </span><span>d. $6000 in bonds; $13,000 in certificates of deposit.

Answer:
7/4
Step-by-step explanation:
To find the reciprocal of 4/7, flip the fraction.
The numerator goes in the denominator and the denominator goes in the numerator
7/4
Just multiply the two, your answer should be 21.06
Let's solve for x.
2x−9y=14
Step 1: Add 9y to both sides.
2x−9y+9y=14+9y
2x=9y+14
Step 2: Divide both sides by 2.
2x
/2
=
9y+14
/2
x=
9
/2
y+7
Answer:
I really hope this help! Some may call it front end rounding while others call is front end estimating, even though they mean the same thing. When rounding a place value, you need to look to the number to the right of it. Example: Most often a teacher may as you round the number 452 to the nearest ten’s. That number will than be 450. But why? Well as we look at the number, we know we need to round to the nearest ten. So in our case it would be 52. Our rule to remember when rounding is 5 and higher we round-up. Since we are looking at the portion of the number 52, we go right of the tens place to find the number 2. Since the number 2 is not 5 or higher, we round down making it 50. Don’t forget to finish the problem by adding the hundreds back to the original number. Your answer for this problem is 450.
