Step-by-step explanation:
Answer:
pencils amount = 9 pens amount= 9
Step-by-step explanation:
We start this problem forming two linear equations system.
3*X+7*Y=90
Where X is the amount of pencils and Y is the amount of pens
The second equation is given by the statement, the amount of pencils is equal to the amount of pens, so the second equation is:
X=Y
Merging both equations we have:
3*X+7*X=90
Solving for X we have:
10*X=90
X=9
X=Y=9
Answer:
d = 1.4 t + 30
Step-by-step explanation:
Head start means any advantage achieved or advantage gained in any race or competition.
In the context, the runner is gained a head start of 30 meter from the starting point.
It is also given that the speed with which the runner is running is 5.0 km per hour.
Therefore, the equation that gives the distance covered by the runner from his start line at any time in seconds is given by d = 1.4 t + 30.
Answer:
Step-by-step explanation:
Area of Trapezoid= (a+b)*h/2
Here a nd b are the bases.
a = 7 ft; b = 5 ft; h = 4 ft
= 24 square feet
