Percentage of protein is calculated as thus:




Answer:
4 pound
Step-by-step explanation:
From the question :
2 gallons of water = 8 pound bag
Number of pound bag per gallon of water ;
Let the number of pound = x
Using cross multiplication, we'll have :
2 gallons = 8 pounds
1 gallon = x pounds
Cross multiply
2x = 8
x = 8 /2
x = 4
Hence, 1 gallon of water mixes 4 pound bag of concrete.
(x²+4x-12)/(x-2)=0
(x+6)(x-2)/(x-2)=0
x+6=0
x=-6
(-6,0)
X= -1/3 (negative x-intercept)
x=4 (positive x-intercept)
Answer:
The coefficient of q is 7
Step-by-step explanation:
The two expressions are
(23q – 34) and (–16q – r)
and .
(–16q – r)
The sum of the two expressions is
23q - 34 + -16q - r
When we group like terms the expression will be,
=23q - 16q - r - 34
When we simplify the expression will now be
=7q - r - 34
The coefficient of q is the constant behind q in the expression.
The coefficient of q is therefore 7.
