Answer:

Step-by-step explanation:

This is a neat question

f(x) - g(x) = 2x Add g(x) to both sides

f(x) = g(x) + 2x

Now you need the right hand side to have 20 added to g(x).

2x must = 20

2x = 20 Divide by 2

x = 20/2

x = 10

So the answer must be x = 10

Housing costs are what percentage of monthly net income? Use the budget sheet to calculate. Round your answer to the nearest who

GenaCL600 [577]

Net income is 1875
the expenses are listed in the table.
to find the percentage, divide the cost of the expense by the net income:

housing = 430 / 1875 = 0.229 = 22.9%
food = 300 / 1875 = 0.16 = 16%
utilities = 125 / 1875 = 0.066 = 6.6%
transportation = 320 / 1875 = 0.17 = 17%
savings = 500 / 1875 = 0.266 = 26.6 %
other = 200 / 1875 = 0.106 = 10.6%

round the percentages to whole numbers if needed

Solve. M/9 = 8 A m = 1.1 B m = 17 C m = 27 D m = 72

Eddi Din [679]

Answer:

D. m=72

Step-by-step explanation:

M/9=8
To get rid of the 9, you have to multiply both sides by 9
M/9 ×9=8×9
M=8×9
8×9=72
M=72

In ∆ABC the angle bisectors drawn from vertices A and B intersect at point D. Find m∠ADB if: m∠C=γ

mylen [45]

Answer:

∠ADB = γ/2 +90°

Step-by-step explanation:

Here's one way to show the measure of ∠ADB.

∠ADB = 180° - (α + β) . . . . . sum of angles in ΔABD

∠ADB + (2α +β) + γ + (2β +α) = 360° . . . . . sum of angles in DXCY

Substituting for (α + β) in the second equation, we get ...

∠ADB + 3(180° - ∠ADB) + γ = 360°

180° + γ = 2(∠ADB) . . . . . . add 2(∠ADB)-360°

∠ADB = γ/2 + 90° . . . . . . . divide by 2

_____

To find angles CXD and CYD, we observe that these are exterior angles to triangles AXB and AYB, respectively. As such, those angles are equal to the sum of the remote interior angles, taking into account that AY and BX are angle bisectors.
