<span>0.03x+20=0.07x+5 original equation
</span>0.03x+20-0.03x=0.07x+5-0.03x <span>subtract 0.03x from both sides to combine like terms
</span>20=0.04x+5
20-5=0.04x+5-5 subtract 5 from both sides
15 = 0.04x
15/0.04 = 0.04x/0.04 divide both sies by 0.04 to get x alone.

Answer: a. 374.4321
Step-by-step explanation:
Taking the central limit theorem(number of samples is large) into consideration, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/(σ/√n)
Where
x = annual sales per square foot .
µ = mean annual sales per square foot
σ = standard deviation
n = number of samples
From the information given,
µ = $370
σ = $38.54
n = 64
The probability value is 18/100 = 0.18
Looking at the normal distribution table, the z score corresponding to the probability value is - 0.92
Therefore,
- 0.92 = (x - 370)/(38.54/√64)
x - 370 = - 0.9 × 4.8175 = 4.33575
x = 370 + 4.4321 = $374.4321
<span>D No, it is not. A straight angle has a measure greater than 90°, but it is not an obtuse angle.
The sentence should say: </span>An obtuse angle is an angle whose measure is greater than 90° but less than 180°
