In the paper airplane shown
Murrr4er [49]

Answer:

∠GHE = 55°

Step-by-step explanation:

ABCD is a quadrilateral (4 sided figure). We know that the sum of the interior angles (4 angles) of a quadrilateral in 360°.

Thus, A + B + C + D = 360

<em>we know b = c = 90 and a = 125, thus we can find D.</em>

<em>125 + 90 + 90 + D = 360</em>

305 + D = 360

D = 360 - 305 = 55°

<u>Note:</u> since Quadrilateral ABCD is congruent to Quadrilateral EFGH, then the measure of D is equal to measure of H (Angle GHE). Thus

∠GHE = 55°

2nd answer choice is correct

Richard’s checking account balance was $57.34 at the beginning of the week. During the week, he recorded the transactions below.
Tomtit [17]

Answer:

US$ 132.45

Step-by-step explanation:

See attachment for the missing table.

Given:

Richard’s checking account balance at the beginning of the week = $57.34

<u>Richard’s account balance at the end of the week from the given table:</u>

Deposits of the week = US$ 163.75

Expenses of the week = Groceries + Credit card bill + Gas

Expenses of the week = 25.37 + 50 + 13.27

Expenses of the week = US$ 88.64

Richard’s account balance at the end of the week = Richard’s checking account balance at the beginning of the week + Deposits of the week - Expenses of the week

Replacing with the real values:

Richard’s account balance at the end of the week = 57.34 + 163.75 - 88.64

                                                                                    =US$ 132.4

Substitute 3x+y=4 5x-y=22
Mrac [35]
Simultaneous Equations

3x + y = 4
5x  - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
