Step-by-step explanation:
2x - x + 9 + 3x - 2 = 16
Combine like terms
4x + 7 = 16
Subtract 7 from both sides
4x = 9
Divide both sides by 4
x = 9/4

Fraction ?
percent?
Answer:
Percentage of china's population to world = 19.85 % (Approx.)
Step-by-step explanation:
Given:
Population of China shows in 2014 = 1.39 billion
Find:
Fraction of china's population to world
Percentage of china's population to world
Computation:
Approximately population of world = 7 billion
Fraction of china's population to world = 1.39 / 7
Percentage of china's population to world = [1.39 / 7]100
Percentage of china's population to world = [0.1985]100
Percentage of china's population to world = 19.85 % (Approx.)

110ft²
Area of figure=(10×8)+(1/2×6×8)
=80+24
=112 ft²
=110 ft² (to nearest tenth)
Math help please show work
Answer:
Step-by-step explanation:
To overestimate the area would mean that you completely enclose the circle in squares; an 8 x 8 square to b exact. The area of a square with sides measuring 8 is 64. The overestimation is 64.
To underestimate the area would mean that you only count the squares that are completely inside the circle. That would be a 6 x 6 square (even though the 6th squares are a tiny bit outside the circle). A square with sides of 6 has an area of 36. The underestimation is 36.

Answer:
Step-by-step explanation:
Range is y thing, where as domain is an x thing. The way you state a range (or a domain, for that matter) is to start from the low point on the graph and go up to the high point. Our graph doesn't have a starting point; therefore, the "low" end of the graph comes up from -∞. The high point on the graph maxes out at 3. Therefore, the proper way to state the range (depending upon whether you use set-builder or not) is
R = (-∞, 3] or another way to state this is
R = {y | y ≤ 3} which reads "y such that y is less than or equal to 3".
. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.
Answer: [tex]3^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Monday was [tex]-5^{\circ}C[/tex]
By Tuesday, it becomes [tex]-2^{\circ}C[/tex]
Change in temperature is the difference between the two temperatures.
[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]
Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

A carpenter has two pieces of wood. He wants to find the density of each piece.
The first piece came from a birch tree. The piece of birch wood measures 2 meters by 4 meters by 3 meters and weighs (mass) 16 kilograms.
The second piece came from a cypress tree. The piece of cypress wood measures 3 meters by 5 meters by 2 meters and weighs (mass) 15.3 kilograms.
Which piece of wood has a greater density?
Answer:
The wood from the birch tree has a greater density than the wood that came from the cypress tree.
Step-by-step explanation:
Density formula: mass/volume
2 times 4 times 3=24 meters for the volume
Birch tree: 16/24 is the density
3 times 5 times 2=30 meters for the volume
Cypress tree: 15.3/30 is the density
If we convert the densities of each piece of wood to decimal it will be easier to determine which has a greater density.
So birch tree: 0.6 repeating is the density
Cypress tree: 0.51 is the density
Therefore the wood that came from the birch tree has a greater density than the wood that came from the cypress tree.

The ratio of the number of red balls to yellow balls in a bag is 4:5. There are 270 balls in
the bag. Which statement is TRUE?
Answer:The ratio of the number of red balls to yellow balls in a bag is 4:5 there are 270 balls in the bag
Step-by-step explanation:
As per linear equation, there are 120 red balls and 150 yellow balls in the bag.
What is a linear equation?A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.
Given, the ratio of the number of red balls to yellow balls in a bag is 4:5. There are 270 balls in the bag.
Let, there are 4x red balls in the bag.
Therefore, there are 5x yellow balls in the bag.
Now, (4x + 5x) = 270
⇒ 9x = 270
⇒ x = 270/9
⇒ x = 30
The number of red balls = 4x = 4 × 30 = 120.
The number of yellow balls = 5x = 5 × 30 = 150.

WILL GIVE BRAINLIEST AND THANKS. determine if these are tangent to the circle
Answer:
19 Five is not tangent to the circle.
20 Eight is tangent to the circle.
Step-by-step explanation:
In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.
I don't think the diagram on the left is, but I'll check it.
5^2 + 12^2 =
25 + 144 =
169
square root of 169 is 13
The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5 units long does not make a tangent to the given circle.
The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.
The radius and the distance to the external point form a right angle.
The Pythagorean triple is
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B).
and
If A and B are inclusive events, then P(A or B) = P(A) + P(B) - P(AB).
Si hay 30% de probabilidad de que neve y llueva en día de hoy. Si la probabilidad de
lluvia es 40% y la probabilidad de nieve es de 15%. ¿Cuál es la probabilidad de que caída
nieve o llueva en el día de hoy?
Answer:
P(A or B) = 25%
Step-by-step explanation:
P(A and B) = 30%
P(A) = 40%
P(B) = 15%
Apply given formula:
P(A or B) = P(A) + P(B) - P(AB)
= 40%+15+-30%
