Answer:

4 1/12

Step-by-step explanation:

a = 5/6        b = 3 1/4 = 13/4

To add 5/6 + 13/4, we have to make the denominators the same:

20/24 + 78/24 = 98/24
To make it back to a mixed fraction:

4 2/24
4 1/12

Answer:

4\frac{1}{12}

Step-by-step explanation:

Given the following question:

a+b
a=\frac{5}{6}
b=3\frac{1}{4}
\frac{5}{6} +3\frac{1}{4}

To find the answer we have to convert the mixed number into an improper fraction, find the common denominator, and then add the numerators.

\frac{5}{6} +3\frac{1}{4}
3\frac{1}{4} =4\times3=12+1=\frac{13}{4}
\frac{5}{6} +\frac{13}{4}
\frac{5}{6} \times4=\frac{20}{24}
\frac{13}{4} \times6=\frac{78}{24}
20+78=98
\frac{98}{24} \div2=\frac{49}{12}
\frac{49}{12} =49\div12=4\frac{1}{12}
=4\frac{1}{12}

Hope this helps.

Answer:

(2,-2)

Step-by-step explanation:

y=-4x+6

y=3x-8

plug the y's in for each other to get:

-4x+6=3x-8   <----- solve from there

+8            +8

-4x+14=3x

+4x         +4x

14=7x

/7     /7

x=2

now plug the x in to get y (in any problem)

y=3(2)-8

y=6-8

y=-2

Isabella has twice as much money invested at 4% as she has invested at 3%, and she has $500 more invested at 5% than she has at
adell [148]
Invested at 3% = x
invested at 4% = 2x
invested at 5% = x+500

0.03x + 0.04(2x) + 0.05(x+500) = 2025
0.03x + 0.08x +0.05x +25 = 2025
0.16x = 2000
x= 12,500
4% = 2x = 12,500 * 2 = $25,000
