Find the missing value
Answer:
-12
Step-by-step explanation:
Let's replace that blank with x for now ;)
x - (-5) = -7
First, let's change that -(-5) to +5 because subtracting negatives is the same as adding.
x + 5 = -7
Subtract five from each side.
x + 5 = -7
-5 -5
x = -12
So then we change that x back to the blank and fill it in with -12.

Answer:
Question 2. 12% of 650 = 78
Step-by-step explanation:
100% = 1 in decimal form.
This is because finding 100% of something is the same as multiplying it by 1:
E.g. 100% of 10=10, 10x1 = 10
Therefore to find a percentage of something, we simply need to multiply it by the decimal form of that percentage. For example, if we were finding 50% of 10 (half), 50% in decimal form is 0.5, 10x0.5 = 5
The percentage here is 12%, we can find the decimal form by dividing it by 100, 12/100 = 0.12
So, in order to find 12% of 650, we just need to multiply 650 by 0.12:
650x0.12 = 78
12% of 650 = 78

2/5 divided by 5/6 is? Express ur awnser in the simplest form. DIVIDING FRACTIONS! pls help right away and thx :)
2/5 divided by 5/6 equals 12/25.
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, to divide 2/5 by 5/6, we multiply 2/5 by the reciprocal of 5/6.
Reciprocal of 5/6 = 6/5
Now, we can multiply the fractions:
[tex]\frac{2}{5} \times \frac{6}{5}[/tex]
[tex]= \frac{2 \times 6}{5 \times 5}[/tex]
[tex]= \frac{12}{25}[/tex]
Therefore, 2/5 divided by 5/6 equals 12/25.

You need at least $40 to buy some notebooks, but your parents don’t want to give you more than $50. Write an inequality representing the possible amount of money you could get.
m = amount of money you receive
You need at least $40, so that means you need m = 40 or more
So [tex]m \ge 40[/tex] which is the same as saying [tex]40 \le m[/tex]. You flip both sides and also flip the inequality sign as well.
At the same time, your parents won't give you more than $50. So the largest m can get is m = 50. This means [tex]m \le 50[/tex]
-----------------
Combine [tex]40 \le m[/tex] and [tex]m \le 50[/tex] to get the compound inequality [tex]40 \le m \le 50[/tex]
This represents all the possible values of m. We see that m can get as small as m = 40, or as large as m = 50, or anything in between.
------------------
Answer: [tex]40 \le m \le 50[/tex]

Complete Question:
On Monday, Sarah has to meet her friend at the park after school. The distance from her house to school is 2x + 5. The distance from school to the park is x. If the total distance she walks that day is 10x + 9, how far is it from the park back to her house?
Answer:
[tex] = 7x + 4 [/tex]
Step-by-step explanation:
Distance from her house to school = 2x + 5
Distance from school to park = x
Total distance walked that day including distance from the park back to her house = 10x + 9
Distance back to her house = total distance walked - (distance form her house to school + distance from school to park)
= [tex] (10x + 9) - ((2x + 5) + (x)) [/tex]
[tex] = (10x + 9) - (2x + 5 + x) [/tex]
[tex] = (10x + 9) - (3x + 5) [/tex]
[tex] = 10x + 9 - 3x - 5 [/tex]
Combine like terms
[tex] = 10x - 3x + 9 - 5 [/tex]
[tex] = 7x + 4 [/tex]

Two angles form a linear pair. One angle measures
2
x
and the other angle measures
10
x
. Find the measure of the smaller angle.
Answer:
30 degrees
Step-by-step explanation:
a linear pair adds up to 180 degrees. therefore, you can compose the equation 2x+10x=180
12x=180
x=15
the smaller angle is 2x, so 2 times 15 is 30

If a person can walk with an average speed of 5 meters/second, how far will they walk in 8 minutes?
Answer:
2,400
Step-by-step explanation: If a person can walk 5 meters per second and there are 60 seconds in a minute then you would multiply 5 by 60 and get 300. Then you multiply that by 8 and get 2,400.
Answer:
5 meters a second
60 seconds in a minute
5 x 60= 300
8 minutes
300 x 8 = 2400 meters in 8 minutes
Step-by-step explanation:
This is a warmup for your first project. The drug valium is eliminated from the bloodstream through a decay process with a half-life of 36 hours. This means that no matter how much drug is in your body, 36 hours later, half will be left. An initial dose of 20 milligrams of valium is taken at midnight. This is actually a version of the mixing-tank problem with the tank representing the circulatory system. If we don’t know something, give it a name (e.g. flow in = rin). Assume that the volume of blood in a person does not fluctuate much, so we can assume it is a constant.
(a) Define your dependent and independent variable with units. Typical volume units for blood is in terms of Liters.
(b) What is the flow rate in? flow rate out? concentration going in? concentration going out? initial condition?
(c) Write the initial value problem (IVP).
(d) Solve your initial value problem.
(e) Use information given to you to determine all constants in your solution.
(f) What is the amount of valium in your body at noon the next day? How long does it take for the drug to reach 10% of its initial level?
Step-by-step explanation:
a. We have v as the amount of drug(mg) in the blood at time t (hrs)
b. Flow rate in = k litre/he
For a circulatory system we have the flow rate in and flow rate out to be the same
Therefore,
Flow rate out = k litre/hr
concentration of drug going in = 0mg/litre
Concentration of drug going out = v mg/litre
V(0) = 20mg since 20mg was taken at midnight
V(0) = 20
Half life t1/2 = 36 hours
V(36) = v(0)/2
= 20/2
= 10mg
C. [tex]ivp = \frac{dv}{dt}[/tex][tex]= -kv[/tex]
[tex]v(0) = 20mg\\v(36) = 10mg[/tex]
d. solution
[tex]\frac{dv}{dt} = -kt\\ln(v) = ln(c) - kt[/tex]
[tex]\frac{v}{c} = e^{-kt} = v=ce^{-kt}[/tex]
v(0) = 20
[tex]ce^{-k(0)} =20[/tex]
c = 20
so
[tex]v(t) = 20e^{-kt}[/tex]
e.
[tex]t\frac{1}{2}=36hours\\ v(36)= 10[/tex]
[tex]10 = 20e^{-36k}[/tex]
[tex]\frac{1}{2} =e^{-36k}[/tex]
we take log
[tex]k=\frac{ln(2)}{36}[/tex]

Decrease 520 by 15% what Is the answer?
Answer:
442
Step-by-step explanation:
If you want to decrease 520 by 15%, you have to multiply 15% by 520 first, which is 78. Next, you have to minus 78 from 520. Now you get 442!
The number is 442 which is obtained after decreasing 520 by 15% the answer is 442.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Let x be the number that is obtained after decreasing 520 by 15%
= (100 - 15)% of 520
= 85% of 520
= 0.85×520
= 442
Thus, the number is 442 which is obtained after decreasing 520 by 15% the answer is 442.
