Answer:
145°
Step-by-step explanation:
The angle is 90°+55°=145°
8% or 8 cents per dollar.
To find the answer, just divide the extra 32 cents charged by the 4 dollars spent to find the amount per dollar, and you should get 8, or 8% tax.
Answer:
x = (-1)/23
Step-by-step explanation:
Solve for x:
-3 x - 4 (x - 1) = 5 (2 x + 1) + 6 x
-4 (x - 1) = 4 - 4 x:
4 - 4 x - 3 x = 5 (2 x + 1) + 6 x
Grouping like terms, -3 x - 4 x + 4 = 4 + (-3 x - 4 x):
4 + (-3 x - 4 x) = 5 (2 x + 1) + 6 x
-3 x - 4 x = -7 x:
-7 x + 4 = 5 (2 x + 1) + 6 x
5 (2 x + 1) = 10 x + 5:
4 - 7 x = 10 x + 5 + 6 x
Grouping like terms, 10 x + 6 x + 5 = (10 x + 6 x) + 5:
4 - 7 x = (10 x + 6 x) + 5
10 x + 6 x = 16 x:
4 - 7 x = 16 x + 5
Subtract 16 x from both sides:
4 + (-7 x - 16 x) = (16 x - 16 x) + 5
-7 x - 16 x = -23 x:
-23 x + 4 = (16 x - 16 x) + 5
16 x - 16 x = 0:
4 - 23 x = 5
Subtract 4 from both sides:
(4 - 4) - 23 x = 5 - 4
4 - 4 = 0:
-23 x = 5 - 4
5 - 4 = 1:
-23 x = 1
Divide both sides by -23:
Answer: x = (-1)/23
Answer:
SAS Postulate
Step-by-step explanation:
In EDG & ADC ,
1) AD = ED ( given )
2)angle( EDG ) = angle ( ADC )................ [ Vertical Opposite Angles are equal ]
3) GD = CD ( D is the mid - point of CG )
So triangles EDG & ADC are congruent by SAS postulate....
Answer:
6. -2.5 + 3 = 0.5
Part B. -2.5 + x = y
4. a. Yes
b. No
c. No
d. Yes
1. C. -1/8 points
3. a. -3.7 + 8 = positive number 8 = a. 4/3 = d.
b. -8 - 1/1/3 = negative number -8 = b, c. -5 = b, d.
c. -8 + 8 = 0 -4.9 = b, d. -5.4 = b, d.
d. -4.52 + -4.9 = negative number 3.8 = a, d. 3.86 = a, d.
Step-by-step explanation:
Those are the correct answers.
