Simplify the following expression (30/45g+20)-(8/9g+7)
amid [387]

The answer is: 13-\frac{2}{9}g

The explanation is shown below:

1- You have the following expression given in the exercise:

(\frac{30}{45}g+20)-(\frac{8}{9}g+7)

2- When you multiply signs, you obtain:

\frac{30}{45}g+20-\frac{8}{9}g-7

3. Now, you must add like terms, as following:

-\frac{2}{9}g+13

4. Therefore, you have that the expression simplified is:

13-\frac{2}{9}g

Find the value of x shown below
irakobra [83]

Angles opposite to the equal sides of an isosceles triangle are equal, so the third angle in this triangle is also 61.  Now, you know all the angles in the triangle, you can use the Triangle Sum Theorem, which says that all the angles in a triangle add up to 180.

x + 61 + 61 = 180

x + 122 = 180

x = 58

Hope this helped!

Show work, please someone help me, i'm confused still on this concept.
BigorU [14]
Answer: choice C) -15x^4y

-----------------------------------------

Explanation:

The coefficients are -3 and 5. They are the numbers to the left of the variable terms
Multiply the coefficients to get -3*5 = -15. So -15 is the coefficient in the answer

Multiply the x terms to get x^3 times x = x^(3+1) = x^4. Notice the exponents are being added

Do the same for the y terms as well: y^2 times y^(-1) = y^(2+(-1)) = y^(2-1) = y^1 = y

So we have a final coefficient of -15, the x terms simplify to x^4 and the y terms simplify to just y

Put this all together and we end up with -15x^4y which is what choice C is showing
