2/7x-23)+5x = 18 (x-1)

Blizzard [7]

Answer:

x= - 35 over 89

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x−23+5x=18(x−1)

x+−23+5x=(18)(x)+(18)(−1)(Distribute)

x+−23+5x=18x+−18

(

x+5x)+(−23)=18x−18(Combine Like Terms)

x+−23=18x−1837

x−23=18x−18

Step 2: Subtract 18x from both sides.

x−23−18x=18x−18−18x

−89

x−23=−18

Step 3: Add 23 to both sides.

−89

x−23+23=−18+23

−89

x=5

Step 4: Multiply both sides by 7/(-89).

HELP An investor invested a total of $2,800 in two mutual funds. One fund earned 5% profit while the other earned 3% profit. If

Musya8 [376]

Answer:

The amount invested in the mutual fund that earned 5% was $1,000

The amount invested in the mutual fund that earned 3% was $1,800

Step-by-step explanation:

Let

x ----> the amount invested in the mutual fund that earned 5%

y ----> the amount invested in the mutual fund that earned 3%

we know that

$x+y=2,800$ ----> $y=2,800-x$ ----> equation A

$5\%=5/100=0.05$

$3\%=3/100=0.03$

$0.05x+0.03y=104$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$0.05x+0.03(2,800-x)=104$

Solve for x

$0.05x+84-0.03x=104$

$0.05x-0.03x=104-84$

$0.02x=20$

$x=\$1,000$

<em>Find the value of y</em>

$y=2,800-x$

$y=2,800-1,000=\$1,800$

therefore

The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800

I WILL MARK BRAINLIEST WHAT DOES THIS MEAN????

bogdanovich [222]

Answer:

The answers are: 1 and 1.

Step-by-step explanation:

I believe they are how combinations are written. In other words:

$_{n}C_{r}=(\frac{n}{r})=n!/(r!(n-r)!)$ (Ignore the fraction bar, I can't really format it properly).

Anyways, simply find the combination of each:

$(\frac{9}{0})=9!/(0!(9-0)!)=9!/9!=1$

$(\frac{9}{9} )=9!/(9!(9-9)!)=9!/9!(0!)=9!/9!=1$

Note that 0! equals 1.
