Step-by-step explanation:

Let x be the number of running plays
Y be the number of
passing plays
Since the total plays is 110
X + y = 110
And total yard is 378
3x + 7y = 378
Using the first equation
X = 110 – y and substitute to the 2nd equation
3(110 – y) + 7y = 378
And solve for y
Y = 12
Substitute to eqution 1
X = 110 – 12 = 98
Answer:
x=
−1
/2 , y−4

Answer:
<h2>45 in²</h2>
Step-by-step explanation:
Formula:
area of a parallelogram = base × height
==================================
By reading the figure :
base = 15
height = 3
Therefore,
The area of the parallelogram = 15 × 3
= 45
Answer: x = 4
Step-by-step explanation: 6x - 27 + 3x = 4 + 9 - x
or, 10x = 40
or, x = 4 ( hope this helps )
