Question 1:
If you know that 3 squares equals 7 circles and the squares are being counted by 3, then continue to count the circle by 3 until you get 25 circles.
Example:
3 Squares : 7 circles
4 squares : 10 circles
5 squares : 13 circles
6 squares : 16 circles
7 squares : 19 circles
8 squares : 22 circles
9 squares : 25 circles Add 9 squares to 3 = 12
You will have 12 squares when continues to count all the way to 25 circles.
Question 2:
Just multiply 14 by 28 and you will get your answer. Which is 3. The missing digit's 3. You can then check by doing 392 ÷ 14 to see if you get 28.
the answer is 1.5 over 24. 1.5/24
X+2,000=stocks
x=bonds
7.2%⇒(.072)(x)=bonds invested
6%⇒(.06)(x+2,000)=stocks invested
Here is the equation:
x(.072)=(.06)(x+2,000) | Since the income from both equal
You then solve each side first (assume you know how to but if not, let me know)
You first multily the parentheses/x variables
⇒.072x = .06x+2,000(.06)
⇒.072x = .06x+120
You then minus .06x from each side
⇒.012x = 120
You then divide each side by .012
.012x÷.012=x
120÷.012=10,000
x=10,000
Now change the original x variables with 10,000
.072($10,000)=$720 bond interest
<u>They are equal so $720×2=$1440</u>
-9x + y = 17
9x + 9y = 19
------------------add
10y = 36
y = 36/10 = 18/5 <==
She read 27 minutes already (90 x .30) and has 63 minutes 1 hour and 3 minutes left (90-27).
