Answer:

y=5/6\approx0.83

Step-by-step explanation:

So we have the equation:

5(2y+1)=4y+10

First, let's distribute the left side of our equation:

5(2y)+5(1)=4y+10

Multiply:

10y+5=4y+10

Now, let's isolate the y-variable. Subtract 4y from both sides:

(10y+5)-4y=(4y+10)-4y

The right side cancels. Subtract on the left. So:

6y+5=10

Now, subtract 5 from both sides:

(6y+5)-5=(10)-5

The left side cancels. Subtract on the right:

6y=5

Now, divide both sides by 6. So:

\frac{6y}{6}=\frac{5}{6}

The left will cancel. Therefore:

y=5/6\approx0.83

And we're done!

5(2y+1)=4y+10(multiply 5 to 2y and 1)
10y+5=4y+10(subtract 5 from 5 and 10)
10y=4y+5(subtract 4y from 4y and 10y)
6y=5(divide 6 by 6y and 5)
y=0.83

A(1)=20
Paladinen [302]

Answer:

-14

Step-by-step explanation:

You've got a(1)=20

a(1) means a(n) when n=1

the sequence is telling you to take the previous value of a(n), which is a(n-1) and subtract 17

then:

a(2) = a(1)-17 = 20 - 17 = 3

a(3) = a(2) - 17 = 3-17 = -14

Compute $121_3+2122_3-1200_3-2111_3$. Express your answer in base 3.
vfiekz [6]

Answer:

-221 base 3

Step-by-step explanation:

We are to calculate the value of the numbers in base 3. One of the ways to do that is to first convert each number to base 10. Do the arithmetic, then convert back to base 3.

121 base 3 +2122 base 3 - 1200 base 3 - 2111 base 3

Let's convert to base10

See attachment for details

From the workings,

121 base 3 + 2122 base 3 - 1200 base 3 - 2111 base 3 = -221 base 3

Select the correct answer.<br><br> Which expression is equivalent to sin^2x-sinx-2/sinx-2?
ladessa [460]

Answer:

A

Step-by-step explanation:

We are given:

\displaystyle \frac{\sin^2(x)-\sin(x)-2}{\sin(x)-2}

To make it simpler and more clear, we can let u = sin(x). So:

\displaystyle \frac{u^2-u-2}{u-2}

Now, it becomes obvious that we can factor, which produces:

\displaystyle =\frac{(u-2)(u+1)}{u-2}

Cancel:

=u+1

And substituting back:

=\sin(x)+1

Hence, our answer is A.
