Answer:
1.75=b
Step-by-step explanation:
do the equation:
-2=3/4(5)+b
-2=-3.75+b
+3.75 to both sides
1.75=b
I found that Joe has 28 red pepper plants and 8 green pepper plants.
to find this, I first set up a proportion:
7/2 = (20+x)/x
then you cross multiply giving you:
7x = 40 + 2x
Subtract 2x from both sides:
5x = 40
solve for x:
x = 8 (which is the amount of green pepper plants)
to find how many red pepper plants he has, plug in x for (20 + x) giving you 28 red pepper plants
Hope I helped :)
Answer:
(11a+b+1)
Step-by-step explanation:
(1): "a2" was replaced by "a^2". 2 more similar replacement(s). (((((3•(a2))•b)+5ab)-4ab)+(a•(b2)))+(23a2•b) ((((3a2 • b) + 5ab) - 4ab) + ab2) + 23a2b Pull out like factors :
11a2b + ab2 + ab = ab • (11a + b + 1)
