When x+2 = 1/5y is written in standard form, what is the value or B
Ket [755]

Answer:

B=-1

Step-by-step explanation:

Standard form is Ax+By=C.

In this case, Ax is x, By is 1/5y, and C is +2.

To isolate the 2 (the C), subtract x from both sides of the equation:

x+2=1/5y

-x     -x

2=-x+1/5y.

Now, the value of B, the x value, is -1.

Whats 1 4/5 as a percent?
Sunny_sXe [5.5K]
4/5 as a percent would be 80% because 100 divided by 5 is 20 then multiply by 4 which is 80%. Then for the 1 which is a whole equals 5/5 so it would be 100% which you add to the percent of the 4/5 and it would be 180% total.

hjlf

Answer:

a^2-ab+3ab^2-2b^2

Step-by-step explanation:

-2a^2b+a^2-5ab+3ab^2-b^2+2(a^2b+2ab)

Open parenthesis

-2a^2b+a^2-5ab+3ab^2-2b^2+2a^2b+4ab

Add

-2a^2b+2a^2b=0

We have

a^2-5ab+3ab^2-2b^2+4ab

Add

-5ab+4ab=-ab

We have

a^2-ab+3ab^2-2b^2

Does anyone know to do this!
Rina8888 [55]
Answer: (r + 4)(r + 8)
Alright, I would first rearrange the equation by bringing all your terms to one side by adding 12r and 32 to both sides. This will result in the rearranged equation: r^2+12r+32=0
You can then factor the equation into the two binomials: (r + 4)(r + 8).
4 + 8 equals the b term, 12, and 4 x 8 equals the c term, 32.
