Answer:

x = 1 and y = -2

Step-by-step explanation:

Given that,

2x-3y = 8 ..(1)

4x+3y = -2 ..(2)

Add equation (1) and (2),

2x-3y+4x+3y = 8+(-2)

6x = 6

x = 1

Put the value of x in equation (1).

2-3y = 8

2-8 = 3y

-6 = 3y

y = -2

Hence, the value of x is 1 and that of y is -2.

HELP ME PLEASE. Anson borrows some money from a bank at a rate of 10% simple interest for 1 year. Jenny borrows $1000 more then
kondaur [170]
$5000 is the correct answer.

The formula for simple interest is I=prt.  Anson gets 10% interest; 10% = 10/100 = 0.1.  This gives us
I=p(0.1)(1) = 0.1p.

Jenny borrows 1000 more than Anson, so her principal is p+1000.  Her rate is 8%; 8%=8/100 = 0.08.  She invests it for half of a year, or 0.5. Together this gives us:
I=(p+1000)(0.08)(0.5)
= (p+1000)(0.04)
= p*0.04 + 1000*0.04
= 0.04p + 40

Together they earned 740:
0.1p+0.04p+40 = 740

Combine like terms:
0.14p+40 = 740

Subtract 40 from both sides:
0.14p+40-40 = 740-40
0.14p = 700

Divide both sides by 0.14:
0.14p/0.14 = 700/0.14
p = 5000

c. How much longer does Sana spend in the bathroom than Ali ? Mother Showers, washes and dries hair, brushes teeth ¾ hour Father
PilotLPTM [1.2K]

Answer:

Sana takes 10 minutes longer than Ali in bathroom

Step-by-step explanation:

Given:

Ali Showers, brushes teeth 20 minutes

Thus, Ali takes 20 minutes time in bathroom

Sana Takes a bath, brushes teeth ½ hour

1 hour has 60 minutes

1/2 hour has 60/2=30 minutes

Thus, Sana takes 30 minutes time in bathroom.

Time, taken more by sana than Ali = 30 minutes - 20 minutes = 10 minutes

.

Thus, Sana takes 10 minutes longer than Ali in bathroom.

Which expression is equivalent to (16x^8y^-12)^1/2
MAVERICK [17]

Answer:

The equivalent expression is \Rightarrow \dfrac{4x^4}{y^6}

Step-by-step explanation:

Given: (16x^8y^{-12})^{1/2}

We need to simplify the expression. We will distribute radical with each term inside the parentheses.

\Rightarrow (16x^8y^{-12})^{1/2}

Distribute the radical

\Rightarrow 16^{1/2}\cdot x^{8\cdot 1/2\cdot y^{-12\cdot 1/2}

\Rightarrow 4\cdot x^4\cdot y^{-6}

\Rightarrow 4x^4y^{-6}

Now we will simplify the negative exponent.

\Rightarrow \dfrac{4x^4}{y^6}

Hence, The equivalent expression is \Rightarrow \dfrac{4x^4}{y^6}
