Answer: 156.25
Step-by-step explanation:
Answer:
y = 1
d = 4
Step-by-step explanation:
8y - 2d = 0 ---------------(I)
5y + 4d = 26 1/4
5y + 4d = 105/4 ------------------(II)
(I)*2 16y - 4d = 0
(II) <u>5y + 4d = 105/4</u> {add (I) &(II)}
21y = 105/4

Substitute y =1 in equation (I)
8*1 - 2d = 0
8 - 2d = 0
-2d = -8
d = -8/-2
d = 4
Answer:
Infinite number of solutions
Step-by-step explanation:

For any value of x, both equations are equal to each other because both sides are identical
10*a = 10000000
a = 1000000, one million
5*10*b = 500000000
b = 10000000, ten million
About ten times.
