Answer:
wilma is 22.5 mph
fred is 25.5 mph
Step-by-step explanation:
Time:40 minutes, or 2/3 hours
Speed:
Fred:x+3
Wilma: x
Distance:32 miles
2/3(x+x+3)=32
2/3(2x+3)=32
1 1/3x+2=32
4/3x=30
x=22.5
wilma is 22.5 mph
fred is 22.5+3= 25.5 mph
Answer:
<h2>
3.6° and 86.4°</h2>
Step-by-step explanation:
24x - measure of an angle
x - the measure of a complementary angle
Complementary angles adds to 90°
x + 24x = 90°
25x = 90°
x = 90°÷25
x = 3.6°
24x = 24·3.6° = 86.4°
That would be a unique triangle
6x(3x + 1) = 0
First, distribute the 6x to both 3x and 1
6x(3x) = 18x²
6x(1) = 6x
18x² + 6x = 0
To solve, find a number (x) that, when placed in the value of x, will give 0.
0 will be that answer.
18(0)² = 0
6(0) = 0
0 + 0 = 0
0 should be your answer
