So we know nothing about blank so we can infer that’s our X in this case
So 4/5x=2/5 do inverse multiplication for 4/5 to get rid of it from the left side so you’re left with
X=5/4*2/5 just multiply across and you get 10/20 now simplify
1/2
Step-by-step explanation:
5(r + 9) - 2(1 - r) = 1
5r + 45 - 2 + 2r = 1
7r + 43 = 1
7r = -42
r = -6.
We can use the rule of three to figure out what's 5% of 79:
100/79=5/x
x= (79*5/100)=3.95
Let's add said 5% to 79:
79+3.95=82.95
Identify the OUTLIER among the following data set: 5, 6, 1, 0, 6, 4, 2, 19, 6, 1, and 3.

Answer: 19
Step-by-step explanation: It's not close to any of the other numbers, if you put it on a dot plot you can see it's farther down.
Answer: the perimeter of the shape is 19.1
Step-by-step explanation:
To determine the length of each side of the quadrilateral, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side
For line AD,
AD² = 2² + 4² = 4 + 16 = 20
AD = √20 = 4.47
For line AB,
AB² = 1² + 5² = 1 + 25 = 26
AB = √26 = 5.1
For line BC,
BC² = 2² + 4² = 4 + 16 = 20
BC = √20 = 4.47
For line CD,
CD² = 1² + 5² = 1 + 25 = 26
CD = √26 = 5.1
The perimeter of a plane figure is the distance around the figure. Therefore
Perimeter = AB + AB + BC + CD
Perimeter = 4.47 + 5.1 + 4.47 + 5.1 =
19.1
