(SAT PREP) Find the value of x.
(I have several, please help!!)
question 1 :- sum of all angles of a triangle is 180°
so, x + 39° + 25° + 15° = 180°
⇒x + 79° = 180°
⇒x = 101°
question 2 : draw the along with AD and make and triangle as shown in figure.
as ABCD is a parallelogram. so, angle FDE = 180° - x
and angle FED = 180° - x [ as FEA + FED = 180° ]
now from ∆DEF,
50° + 180° - x + 180° - x = 180°
⇒230° - 2x = 0
⇒x = 105°
also read : If (A + B) =(A-B) then the angle between the Ả and B.

What is the volume of the sphere with the radius of 9 and round to the hundredths
Answer:
3046.389 units
Step-by-step explanation:
Given data
r=9units
Volume of sphere
V= 4/3πr^3
substitute
V= 4/3*3.142*9^3
V=1.33*3.142*729
V=3046.388 units
Hence the volume is 3046.389 units

Last month Albert earned half of what Betty earned, while Betty earned $5000 more than what Calvin earned. If Donna earned twice what Calvin earned and Albert and Betty together earned $900 more than what Calvin and Donna earned together, how much did each person earn?
Answer:
Calving earning = 4400
Betty earning = 9400
Albert earning = 4700
Donna = 8800
Step-by-step explanation:
Given that :
Calving earning = c
Betty earning = c + 5000
Albert earning = (c + 5000) /2
Donna = 2c
c + 5000 + (c + 5000) /2 = 900 + c + 2c
c + 5000 + 0.5c + 2500 = 900 + 3c
1.5c + 7500 = 900 + 3c
7500 - 900 = 3c - 1.5c
6600 = 1.5c
c = 6600 / 1.5
c = 4400
Calving earning = c = 4400
Betty earning = 4400 + 5000 = 9400
Albert earning = (4400 + 5000) /2 = 4700
Donna = 2(4400) = 8800

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
x=2
