G + 48 = 89<br> g = ?<br> Waht does the g mean?

Mashcka [7]

Answer:

g is a variable.

Step-by-step explanation:

In this case, you need to solve for g. The problem states that g + 48 = 89. You need to find out what g is by subtracting 48 from both sides of the equation. This gives you g + 48 - 48 = 89 - 48. Therefore g equals 41.

20 POINTS!! What would be the first step to solve this equation?

Anettt [7]

Answer:

C. Add 13 to both sides of the equation.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:

m - 13 = 24

m - 13 (+13) = 24 (+13)

m = 24 + 13

m = 37

You have two circles, one with radius r and the other with radius R. You wish for the difference in the areas of these two circl

gtnhenbr [62]

Answer:

maximum difference of radii = $(r-R)=\frac{1}{2\pi ^{2}}$

Step-by-step explanation:

We know that area of circle is given by

$A=\pi \times (radius)^{2}$

For circle with radius 'r' we have

$A_{1}=\pi \times (r)^{2}$

For circle with radius 'R' we have

$A_{2}=\pi \times (R)^{2}$

Now according to given condition we have

$A_{1}-A_{2}\leq \frac{5}{\pi }$

$\Rightarrow \pi r^{2}-\pi R^{2}\leq \frac{5}{\pi }\\\\\Rightarrow (r^{2}-R^{2})\leq \frac{5}{\pi ^{2}}\\\\(r+R)(r-R)\leq \frac{5}{\pi ^{2}}\\\\\because (a^{2}-b^{2})=(a+b)(a-b)\\\\(r+R)=10(Given)\\\\\Rightarrow(r-R)\leq \frac{5}{10\pi ^{2}}\\\\\therefore (r-R)\leq\frac{1}{2\pi ^{2}}$

Thus maximum difference of radii = $(r-R)=\frac{1}{2\pi ^{2}}$

What is y<br> 27 y + 5 = -9

vodomira [7]

Answer:

y = $\frac{-14}{27}$

Step-by-step explanation:

27y + 5 = -9 -> subtract -9 and 5

(-9) - 5 = -14

27y = -14 divide 27 and -14

(-14)/27

You are then left with

y = $\frac{-14}{27}$
