The formula for the trapezoid is
A=a+b
2h
Since the first equation says y= x-4, substitution that for the y value in x + y = 6
x + x - 4 = 6
add up the x’s to get 2x - 4 = 6
add 4 to both sides to get 2x = 10
divide both sides by 2 to get x = 5
the x value is 5
then, to figure out the y value, substitute 5 for the x value in y = 5-4
the y value is 1
final answer: x = 5 and y = 1
hope this helped!!
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)
