Step-by-step explanation:Step 1: Simplify both sides of the equation.
8(2x+3x+2)=−4x+148
(8)(2x)+(8)(3x)+(8)(2)=−4x+148(Distribute)
16x+24x+16=−4x+148
(16x+24x)+(16)=−4x+148(Combine Like Terms)
40x+16=−4x+148
40x+16=−4x+148
Step 2: Add 4x to both sides.
40x+16+4x=−4x+148+4x
44x+16=148
Step 3: Subtract 16 from both sides.
44x+16−16=148−16
44x=132
Step 4: Divide both sides by 44.
44x

answer: x=3
We have been given that during one period extreme cold, the average daily temperature decreased degree F each day. We are asked to find number of days it will take for the temperature to decrease by 9 degree F.
First of all we will convert our mixed fraction into improper fraction.
Now we will divide total temperature change (9) by average daily temperature change () to find number of days.
Dividing a number by a fraction is same as multiplying the number by reciprocal of the fraction.
Therefore, it will take 6 days for the temperature to decrease by 9 degree F.
Answer:
slope = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, - 19) and (x₂, y₂ ) = (- 2, - 7)
m = = = - 4
