3x+2y=2
2x+2y =-7
Answer:
x= 9
y=-12.5
Step-by-step explanation:
3x+2y = 2×2
2x+2y =-7×3
6x+4y =4
- 6×+6y =-21
-2y =25
y=-12,5
2x+2(-12,5)= -7
2x+-25= -7
2x= -7+25
2x/2=18/2
x= 9

What is the absolute value of the integers, 1-41, 1 +51, 1-61?
Hi there!
absolute value= the opposite of that number if only negative:
Step By Step Explanation:
1-41=41-141-1=40
bring a negative sign if not absolute value.
1+51=51+11+51=52
since it’s already in it’s abolute value it won’t change..
1-61=61-161-1=60
bring a negative sign if nessary..
Therefore, the absolute value for the expression 1-41, 1 +51, 1-61 is 40,52, and 60..
The speed of a fish before jumping out of the water can be represented by the equation s = 3h, where h
represents the height, in centimeters, the fish jumps out of the water and s represents the speed of the fish in
meters per second. If the fish is swimming at 15 meters per second before jumping out of the water, how high
can the fish jump?
Answer: The fish can jump 5m high.
Step-by-step explanation:
Given that
s = 3h
where
h = the height(cm) the fish jumps out of the water
and s = speed of the fish(meters per second) then
3 must have seconds as its unit.
Now, If the fish is swimming at 15 meters per second
Then the fish can jump =
s= 3h
15m/s =3h
h= 15m/s/3s
h= 5 meters

To find this, just divide Y by X. For ex, this could look something like 12 divided 4, 15 divided by 5, or 18 divided by 6.
To figure this out too, you can plug in the X and Y components into the equation to see if it checks out.

2. If you depart Los Angeles at 9:55 am and arrive in Denver, Colorado at 1:05 pm, how long was your flight?
Answer:
2 hours 10 minutes
Step-by-step explanation:
LA has a one hour time zone difference than Denver. So if it was 9:55 am when you left LA, that is LA time. So, in Denver it was 10:55 am. If you land in Denver, Colorado at 1:05 pm it is the same as 12:05 pm in LA. So you can just count the hours from 9:55 am to 12: 05 pm.

Answer:
1. x = 4 2. x = 8 3. p = 30
Step-by-step explanation:
1. x + 7 = 11 check: (4) + 7 = 11
- 7 - 7 11 = 11
x = 4
2. x - 12 = -4 check: (8) - 12 = -4
+ 12 + 12 -4 = -4
x = 8
3. multiply p/5 by 5 it cancels each other out and then you do the same thing to the other side. multiply 6 by 5 and you get 30
check: (30)/5 = 6
6 = 6
30 divided by 5 equals 6

The figure shows the dimensions of two city parks, where ARST XYZ and YX YZ.A city
employee wants to order new fences to surround both parks. What is the total length of the fences
required to surround the parks?
R

230 ft.
T
Z
S
350 ft.
Y
The total length of fences needed to surround the parks is
feet.
Answer:
1860
Step-by-step explanation:
The triangles are reflections of each other and since YX=YZ we know that YZ=350
add 350+350+230=930
930×2=1860 - for both parks

The weight of turkeys is normally distributed with a mean of 22 pounds and a standard deviation of 5 pounds. a. Find the probability that a randomly selected turkey weighs between 20 and 26 pounds. Your answer is . Round to 3 decimals and keep '0' before the decimal point. b. Find the probability that a randomly selected turkey weighs below 12 pounds. Your answer is . Round to 3 decimals and keep '0' before the decimal point.
Answer:
a. 0.443
b. 0.023
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The weight of turkeys is normally distributed with a mean of 22 pounds and a standard deviation of 5 pounds.
This means that [tex]\mu = 22, \sigma = 5[/tex]
a. Find the probability that a randomly selected turkey weighs between 20 and 26 pounds.
This is the pvalue of Z when X = 26 subtracted by the pvalue of Z when X = 20. So
X = 26
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{26 - 22}{5}[/tex]
[tex]Z = 0.8[/tex]
[tex]Z = 0.8[/tex] has a pvalue of 0.788
X = 20
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{20 - 22}{5}[/tex]
[tex]Z = -0.4[/tex]
[tex]Z = -0.4[/tex] has a pvalue of 0.345
0.788 - 0.345 = 0.443
The answer is 0.443
b. Find the probability that a randomly selected turkey weighs below 12 pounds.
This is the pvalue of Z when X = 12. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{12 - 22}{5}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a pvalue of 0.023
The answer is 0.023.
