Answer:
<h2>(4x+z)=13000------1</h2><h2>(4x+z)13000=503000----2</h2>
Step-by-step explanation:
let x be the number of seats in A,
y be the number of seats in B, and
z be the number of lawn seats.
y=3x
the total number of seats is given by
(x+y+z)=13000
put y=3x
(x+3x+z)=13000
(4x+z)=13000------1
also
(4x+z)13000=503000----2
hence the systems of equation is
(4x+z)=13000------1
(4x+z)13000=503000----2
Answer:
13 pounds of grass.
Step-by-step explanation:
You need 20 pounds of grass seed to plant inside the baseball diamond.
The Baseball Diamond is a square of side = 90 ft
The Softball Diamond is a square of side = 60 ft
The ratio of the size of the Baseball Diamond to that of Softball Diamond is:
90: 60 = 3:2
If 3 represents 20 pounds, then 2 represents;
× 20 = 13.33333333 pounds = 13 pounds (rounded to nearest pound)
Answer:
31 feet
Step-by-step explanation:
Find x by using the tangent function. Tangent is the opposite over the adjacent.

The distance rounded was 31 feet.
Ok so the slope of the 2 lines must multiply to -1
first find the given slope of the line
y=mx+b
m=slope
y=4x+1
4=slope
4 times what=-1
-1/4
y=-1/4x+b is form (A)
or
8y=-2x+4b (D)
or
1/4x+y=b
or
x+4y=4b (C)
we see that option B is wrong
amswer is B
Answer: 7.5
