Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5

What is the range of the progress of these projects?
Answer:
Step-by-step explanation:
can u give the answer to the quiz
The range of the project will be equal to 0.82.
What is the range in statistics?When the sample maximum and minimum are subtracted, the range of a set of data is the difference between the largest and smallest values. It uses the same units as the data to express itself.
The given data of the project is,
u 0.87
v 0.31
w 0.08
x 0.05
y 0.19
z 0.5
The range will be calculated as the difference between the maximum value to the minimum value.
Range = 0.84 - 0.05
Range = 0.82
Therefore, the range of the project will be equal to 0.82.

Jada walks up to a tank of water than can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
a. At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
b. How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
c. How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.
Answer:
a. rate to empty the tank = - 2/3 gal/min
b, 7.5 min to empty the tank
c. 4.5 min.
Step-by-step explanation:
I use the formula that the work done = rate of work times the time working = W = rt
The work in this problem is emptying the tank.
a. The rate to empty the tank is -2 gal/3 min or - 2/3 gal/min
b. 5/(2/3) = 15/2 = 7.5 min to empty the tank
c. Since 3 gal. had already drained, 3/(2/3) = 9/2 = 4.5 min.

the question is: find the value of x for each equation below and the numbers is
-x+3=3x-2
1.5x-3=2.25x
-1/3x+2=3x-1
Answer:
1. x=5/4
2. x=-4
3. x= 9/10
Step-by-step explanation:
Let's solve your equation step-by-step.
−x+3=3x−2
Step 1: Subtract 3x from both sides.
−x+3−3x=3x−2−3x
−4x+3=−2
Step 2: Subtract 3 from both sides.
−4x+3−3=−2−3
−4x=−5
Step 3: Divide both sides by -4.
−4x/−4 = −5/ −4
x= 5/4
Answer:
x= 5/4 (5 over 4)
Let's solve your equation step-by-step.
1.5x−3=2.25x
Step 1: Subtract 2.25x from both sides.
1.5x−3−2.25x=2.25x−2.25x
−0.75x−3=0
Step 2: Add 3 to both sides.
−0.75x−3+3=0+3
−0.75x=3
Step 3: Divide both sides by -0.75.
−0.75x/−0.75=3/−0.75
x=−4
Answer:
x=−4
Let's solve your equation step-by-step.
−1/3x+2=3x−1
Step 1: Subtract 3x from both sides.
−1/3x+2−3x=3x−1−3x
−10/3x+2=−1
Step 2: Subtract 2 from both sides.
−10/3x+2−2=−1−2
−10/3x=−3
Step 3: Multiply both sides by 3/(-10).
(3/−10)*(−10/3x)=(3/−10)*(−3)

∠A and ∠B are vertical angles. If m∠A=(5x+5)∘and m∠B=(4x+29)∘, then find the measure of ∠A.
Answer:
∠A = 175∘
Step-by-step explanation:
∠A = ∠B
5x-5= 4x+29
x = 34
∠A= 34*5+5
∠A=170+5=175
5x+5= 4x + 29
-5
5x=4x+24
-4x -4x
x=24
m∠A=5x+5
m∠A=5(24)+5

f(x) = x ^ 2 What is g(x)?
Answer:
A ; g(x) = (1/2 x)^2
Step-by-step explanation:
Here, we want to get g(x)
we have a point on the curve g(x)
The point is represented by (2,1)
What this mean here is that, when x = 2, y = 1
Looking at the first option;
Substitute 1 for y and 2 for x
1 = (1/2 * 2)^2
1 = 1
This means this is our answer
The equation for g(x) is;
g(x) = (1/2 x)^2
Which of the following are not perfect squares? Select all that apply.
16
44
81
6
49
24
Answer and Step-by-step explanation:
44, 6, and 24 do not have perfect squares.
To be a perfect square, they have to be able to have a number that, when it multiplies itself by itself (needs to be a whole number), it turns into the bigger number.
44, 6, and 24 can't do this when being square rooted.
16 turns into 4.
81 turns into 9.
49 turns into 7.
#teamtrees #PAW (Plant And Water)
Answer:
44, 6, and 24
Step-by-step explanation:
4²=16 so it's a perfect square
9²=81 so it's a prefect square
7²=49 so it's a perfect square
44, 6, and 24 all result in decimals so it's not a perfect square.
Triangle Congruency please help!!
Answer:
A
Step-by-step explanation:
the nice thing about triangle is that the smallest angle is always opposite the smallest side, etc. also, we can get the remaining angle because we have 2 angles already and there are always 180 degrees in a triangle.
50+ 63= 113
180-113 =67
so, 50 is the smallest angle and thus the side opposite of it is the smallest. next is side bc because 63 is the next biggest angle measure. lastly, side ac is the largest because it's opposite of the largest angle measure

Find the function h(x) = f(x) + g(x) if f(x) = 4^x + 2 and g(x) = x - 4.
h( x) = 4 x + 1 -2
h( x) = 4 x + x + 6
h( x) = 4 x - 4
h( x) = 4 x + x - 2
Answer:
h( x) = 4^x + x - 2
Step-by-step explanation:
h(x)=f(x)+g(x)=4^x+2+x-4=4^x+x-2
Sally bought 4 chocolate bars and 8 lollipops and paid $8.00. Josh bought 3 chocolate bars and 10 lollipops and paid $7.00.
What is the cost of a lollipop? Enter your answer as a decimal
Answer:
Lollipops cost $0.25
Step-by-step explanation:
4C + 8L = $8.00
3C + 10L = $7.00. We need to cancel out chocolate bars
-12C - 24L = $-24.00 Mulitply by -3
12 C + 40L = $28.00 Muliply by 4 Next simplify
16L = $4.00 Divide both sides by 16
L = $0.25
WE CAN EVEN CHECK OUR WORK
4C + 8(0.25) = $8.00
4C = $6.00
C = 1.5
3(1.5) + 10(.25) = $7.00
4.5 + 2.5 = 7
Jose paid $1.12 for a dozen eggs at Target. How much would Jose have to pay for 18 eggs?
Answer:
56.16
Step-by-step explanation: All you do is just multiply
Answer:
$1.67
Step-by-step explanation:
Given it's $1.12 for 12 eggs, we divide 1.12 by 12 to see how much it cost for 1 egg
1.12/12 = 0.093
so 0.093 cents for 1 egg
0.093x18 eggs = 1.674 = $1.67

How many ways can you put the letters in "Utah" in order?
write the set in builder form. A{2,4,6,8}
Answer:A=2,4,6,8
One way of writing this in set builder notation could be:
A={x|2≤x≤8|x2∈N}
Which can be interpreted as:
The set A is the set of any x such that 2≤x≤8 such that half of x is a natural number ( N ).
There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e. ∈ , | , N ), it becomes much easier to “read as a sentence”.
Here are a few more ways of writing the set A=2,4,6,8 in set builder notation:
A={x|2≤x≤8|x∈2⋅N}
A={x|(x−2)(x−4)(x−6)(x−8)=0}
A={x|x=2p|p∈{1,2,3,4}}
A={x∈N|mod(x,2)=0|x≤8}
