Answer:
b. 50
Step-by-step explanation:
The sum of the interior angles of a quadrilateral is 360°, so the missing angle is ...
360° - 110° -40° -80° = 130°
The angle x° is the supplement to this, so is ...
180° -130° = x° = 50°
The value of x is 50.
A consistent system has at least one solution
<span>ƒ(x) = 1/2x + 4
inverse
x = 1/2 y + 4
2x = y + 8
y = 2x - 8
so inverse f-1(x) = 2x - 8
</span>ƒ -1(4) = 2(4) - 8 = 0
answer
ƒ -1(x) = 2x - 8
ƒ -1(4) = 0
Answer:
D The solution is 35, which represents the number of miles she runs each week.
Step-by-step explanation:
Given that Gisele trains 7 days a week, the total of miles she cycles and runs in a week can be divided by 7, or multiplied by 1/7 to find her daily average. Her total number of miles ran for the week combined with her cycling miles multiplied by 1/7 would average 20 miles daily. Since the run is the same each day, using the equation:
1/7(105 + r) = 20 will give the value of 'r' in the number of miles ran per week
105 + r = 140 (multiply both sides by '7')
r = 35 (subtract '105' from both sides)
