Answer:
![(A)x= -8](https://tex.z-dn.net/?f=%28A%29x%3D%20-8)
Step-by-step explanation:
One-fourth x + 2 = ![\frac{1}{4}x+2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7Dx%2B2)
![\frac{1}{4}x+2=-\frac{5}{8}x-5](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7Dx%2B2%3D-%5Cfrac%7B5%7D%7B8%7Dx-5)
Next, we Expand the Left hand Side by multiplying each term in the bracket by 1/4
![\frac{1}{4}x+\frac{2}{4}=-\frac{5}{8}x-5](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7Dx%2B%5Cfrac%7B2%7D%7B4%7D%3D-%5Cfrac%7B5%7D%7B8%7Dx-5)
Bringing terms with x to the left Hand Side i.e. collecting like terms
![\frac{1}{4}x+\frac{5}{8}x=-5-2\\\\(\frac{1}{4}+\frac{5}{8})x=-7\\\\\frac{7}{8}x=-7](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7Dx%2B%5Cfrac%7B5%7D%7B8%7Dx%3D-5-2%5C%5C%5C%5C%28%5Cfrac%7B1%7D%7B4%7D%2B%5Cfrac%7B5%7D%7B8%7D%29x%3D-7%5C%5C%5C%5C%5Cfrac%7B7%7D%7B8%7Dx%3D-7)
On Cross multiplying
7x = -7 X 8
![x=-\dfrac{7*8}{7}\\](https://tex.z-dn.net/?f=x%3D-%5Cdfrac%7B7%2A8%7D%7B7%7D%5C%5C)
x=-8

Answer:
$5.08
Step-by-step explanation:
Step one:
given data
We are told that a credit card company applies a 6% fee on all transactions under $10
since the cost of coffee bellow $10 that is $4.80, the 6% fee is applicable
so
=6% of 4.80
=6/100*4.80
=0.06*4.8
=$0.288
Step two:
the total fee will be
=0.288+4.80
= $5.08
Answer:
(-2,3)
Step-by-step explanation:
4x+5y =7
y = 3x+9
Substitute the second equation into the first equation
4x +5(3x+9) = 7
Distribute
4x + 15x + 45 = 7
Combine like terms
19x +45 =7
Subtract 45 from each side
19x +45-45 = 7-45
19x = -38
Divide by 19
19x/19 = -38/19
x = -2
Now we need to find y
y = 3x+9
Putting in x=-2
y = 3(-2) +9
y = -6 +9
y = 3
(-2,3)
