Answer:
Let's simplify step-by-step.
0.8x+19−0.7x
=0.8x+19+−0.7x
Combine Like Terms:
=0.8x+19+−0.7x
=(0.8x+−0.7x)+(19)
=0.1x+19
Answer:
=0.1x+19

Answer:
-1 :) you can count the number of spaces, divide by 2, and count to the middle by that ammount ;)
<span>The biggest out of the two possible answers is 0.45. 2/5 in decimal form is 0.4, or in percentage form becomes 40%. However, if 0.45 is changed into a fraction, it becomes 9/20 in its smallest form, which is difficult to compare. If we consider 0.45 as a percentage, however, it obviously becomes 45%, which is bigger than 40% so we can confirm that 0.45 is larger than 2/5.</span>
We will use a system of equation for this one.
P=Peanuts; C=Cashews
P+C=20
This represents the pounds.
10P+9C=191
We can make the first equation equal C.
C=20-P
10P+9(20-P)=191
10P+180-9P
P+180=191
P=11
There are 11 pounds of peanuts, which means there's 9 pounds of cashews.
X^2 - 10x + 36 = 0;
We use the quadratic formula: x = ( - b + or - i
)/ (2a);
We have a = 1; b = -10; c = 36;
Then, x = ( 10 + or -i
)/2 = 5 + or -
)/2 ;
