Answer:
p = -2
Step-by-step explanation:
5p - 10 = + 4(1 + 3p)
first get rid of the bracquetes:
5p - 10 = + 4*1 + 4*3p
5p - 10 = + 4 + 12p
subtract left and right of = sign by 5p
5p -5p - 10 = + 4 + 12p -5p
0 - 10 = + 4 + (12p -5p)
subtract left and right of = sign by 4
-10 -4 = 4 -4 + ( 7p )
re arrange
7p + 0 = -14
divide left and right of = sign by 7
7/7 p = -14/7
p = -2
5/8=0.625
4 and 5/8=4+5/8=4+0.625=4.625
you can just seperate the fractions and add
Answer:
B
Step-by-step explanation:
I'm really not sure how to explain this.
Answer:
Step-by-step explanation:
let us assume x to be as x=0
then substitute x value in above equation
let x= -4
therfore, the solutions of the equation 5x-4y=8 is (0,2) and (-4,1)
75/25 = x/100
x = 300
ANSWER: 300
CHECK ANSWER: 300 x .25 = 75
