Answer:
19/2 or 9.5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−5)(2)=36
8x+−40=36(Distribute)
8x−40=36
Step 2: Add 40 to both sides.
8x−40+40=36+40
8x=76
Step 3: Divide both sides by 8.
8x/8=76/8
x=19/2
C - no solution
you take the second solution and times the entire equation by -1
then simply
and you get 0x + 0y = 20
The probability that a randomly selected chocolate bar will have between 200 and 220 calories is 3.97%
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The zscore is given a:
z = (raw score - mean) / standard deviation
mean = 225, standard deviation o = 10.
a) For x = 200:
z = (200 - 225) / 200 = -0.125
For x = 220:
z = (220 - 225) / 200 = -0.025
P(-0.125 < z < -0.025) = P(z < -0.025) - P(z < -0.125) = 0.4880 - 0.4483 = 3.97%
b) For x = 190:
z = (190 - 225) / 200 = -0.175
P(z < -0.025) = P(z < -0.175) = 0.4286

Answer:
In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved. To translate the point P(x,y) , a units right and b units up, use P'(x+a,y+b) .
