Answer:

\huge\boxed{0.5\times10^3=0.5\times1,000=500}

Step-by-step explanation:

(2\times10^5)\div(4\times10^2)=\dfrac{2}{4}\times\dfrac{10^5}{10^2}\\\\\text{use}\ \dfrac{a^n}{a^m}=a^{n-m};\ a\neq0\\\\=0.5\times10^{5-2}=0.5\times10^3=0.5\times1,000=500

Y=300-5x in standard form
Akimi4 [234]
<span>y = 300 - 5x

Standard form:
ax + by = c

</span>y = 300 - 5x
<span>5x + y = 300

Then to find the y-intercept, insert a 0 into the 'x'.
5(0) + y = 300
y = 300
The y-intercept is 300.

To find the x-intercept, insert a 0 into the 'y'.
5x + (0) = 300
5x = 300
x = 60

The x-intercept is 60.</span>

3(r+2)+5(2-r) =-32 can someone tell em the answer to that please
Alex17521 [72]

Answer:

r = 24

Step-by-step explanation:

3(r+2)+5(2−r)=−32

Step 1: Simplify both sides of the equation.

3(r+2)+5(2−r)=−32

(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)

3r+6+10+−5r=−32

(3r+−5r)+(6+10)=−32(Combine Like Terms)

−2r+16=−32

−2r+16=−32

Step 2: Subtract 16 from both sides.

−2r+16−16=−32−16

−2r=−48

Step 3: Divide both sides by -2.

−2r/-2 = -48/-2

r = 24
