Answer:
7
Step-by-step explanation:
add 7 to 3x
Then: 4x-3x=1x which gives:
1x=7
7/1=7
Answer:
m= 5/2
Step-by-step explanation:
Points: (0, 2) and (4, 12)
Slope:
m=(y2-y1)/(x2-x1)
m=(12-2)/(4-0)
m=10/4
m= 5/2

Answer:
Option A is correct.
y = 35.4 bushels per acre when rainfall = 7.1 inches
Step-by-step explanation:
An image of the steps to obtain the equation that relates x to y is attached to this answer.
n = number of variables = 9
μₓ = mean of variable x (rainfall in inches)
μᵧ = mean of variable y (yield in bushels per acre)
σₓ = standard deviation of variable x (rainfall in inches)
σᵧ = standard deviation of variable y (yield in bushels per acre)
y = 4.379x + 4.268
when x = 7.1
y = 4.379(7.1) + 4.268 = 35.3589 = 35.4 bushels per acre.
Explanation:
You make the equation. If she can put 12 on each page then you would multiply 12 by p (pages) and have it equal to 152
152=12p
To solve this, you would divide 12 from both sides
152/12=12.666
Therefore, 12.6=pages but since there aren’t 12.6 pages and you need to keep it a whole number you would round up to 13 because if you kept it at twelve pages you would have those pictures left over.
