7.5× 18.5=138.75 first week
7.5×20=$150 second week
total earnings 138.75+150=$288.75
She did multiply correctly 7.5 ×18.5 but got the wrong figure resulting in in lower pay and she did not multiply the 7.5 × 20 in the seond week. She shouldve added the week one and two wages to get her pay for 2 weeks

Do anyone know how to solve this? need the answer fast.

The value of g^-1(-3) is the value of x that makes g(x) = -3. To find it, we can solve
.. (x +4)/(2x -5) = -3
.. x +4 = -3(2x -5)
.. 7x = 11
.. x = 11/7

The desired value is
.. (3/11)*g^-1(-3)
.. = (3/11)*(11/7)
.. = 3/7

\frac{3}{11} g^{-1}(-3) = \frac{3}{7}

valentina_108 [34]
If Susan had 2$ and got to 12$ we need to find what multiplied by 2 = 12. So, 12/2=6
If 6x2=12 then 11x6=66
66$

Solve for both systems: y+7z=22 and 8y + 7z = 127
7nadin3 [17]
Manipulate the first equation to
y = 22-7z

Then substitute in the second to find z
8(22-7z) + 7z = 127
176-56z+7z = 127
-49z = -49
z = 1

So y = 22-7(1) = 22-7 = 15

y = 15; z = 1
