Answer:
x = 11, y = 3
Step-by-step explanation:
(13x - 19) and (9x + 25) are corresponding angles and congruent, thus
13x - 19 = 9x + 25 ( subtract 9x from both sides )
4x - 19 = 25 ( add 19 to both sides )
4x = 44 ( divide both sides by 4 )
x = 11
Then
13x - 19 = 13(11) - 19 = 143 - 19 = 124
(17y + 5) and 124 are alternate angles and are supplementary, thus
17y + 5 + 124 = 180, that is
17y + 129 = 180 ( subtract 129 from both sides )
17y = 51 ( divide both sides by 17 )
y = 3
Answer:
x=2
Step-by-step explanation:
p and q are 1 point ahead of the previous main one so the beginning and 1
Answer:
A = $3094.58
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Simple Interest Rate Formula: A = P(1 + r)ⁿ
- A is the final amount
- P is the principal amount
- r is the rate
- n is the time (in years)
Step-by-step explanation:
<u>Step 1: Define variables</u>
A = ?
P = 3020
r = 0.05
t = 6 months = 0.5 years
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute: A = 3020(1 + 0.05)^0.5
- Add: A = 3020(1.05)^0.5
- Evaluate: A = 3020(1.0247)
- Multiply: A = 3094.58
And we have our final answer!
Answer:
50 mph, 62 mph
Step-by-step explanation:
Their total speed is found from ...
speed = distance/time
speed = (364 mi)/(3.25 h) = 112 mi/h
If s is the speed of the slower car, then ...
s + (s+12) = 112 . . . . . their total speed is 112 mph
2s = 100 . . . . . . . . . . simplify, subtract 12
s = 50 . . . . . . . the speed of the slower car
s+12 = 62 . . . . the speed of the faster car
