Answer:We are asked to evaluate Marlena's solution in solving the expression below: 2x+5 = -10 -x
The first step is to re-write the expression and transpose same terms in the left side while all numbers are transferred to the right side such as shown below:
Step 0: 2x+5 = -10 -x
Step 1: 2x + x = -10 -5
Step 2: 3x = -15
Step 3: x =-15/3
The answer is x=-5.

Answer:
86 degrees
Step-by-step explanation:
Alrighty, a simple 180-degree triangle, we can see that the two angles add up to 86, so what would make our angle G1 94 since 180-86 = 94, but we are tasked with finding the other side of that angle, let's call it G2, what should we do?
Since this is a flat 180-degree line, we do it again!
180-94 = 86 degrees
And there ya have it
Though, if you need the technical side, it's because a whole of a triangle is 180 degrees
Given that angles F is 58 and E is 28, we add those two up to find angle EGF. How to find EGF you ask? Simple- 180 degrees (Because it's a triangle) minus 86 (Added angles of E and F), that would equal 94.
Now, we are tasked with finding TGF. We do not have TGF but we have EGF. Learning that, we see the line ET, indicating that we have found ourselves a 180-degree line. What do we do with this line? We use it to calculate TGF with EGF
Since EGF is 94, we take the 180 - 94 to equal 86, and that is how you find TGF

A genius society requires an IQ that is in the top 2% of the population in order to join. If an IQ test has a mean of 100 and a standard deviation of 15, which of the following could be used as the minimum qualifying score to join the genius society? 115 130 145 160.
The minimum qualifying score to join the genius society is 130, the correct option is B.
What is the minimum qualifying score?In the top 2%, you have to have an IQ higher than 98% of the population (100% - 2%). This is also known as the 98th percentile.
Given
A genius society requires an IQ that is in the top 2% of the population in order to join.
If an IQ test has a mean of 100 and a standard deviation of 15.
For this problem, you are given the probability and need to determine the raw score.
For the probability, go to the z–table and find the probability that is closest to 0.98. Then look across the row and up the column to determine the z-score.
The closest probability is 0.97982 and that corresponds to a z-score of 2.05.
With a z-score of 2.05, you can use the z formula to compute the raw score.
[tex]\rm z-score=\dfrac{X- mean }{Standard \ deviation}\\\\2.05=\dfrac{x-100}{15}\\\\2.05 \times 15 = x-100\\\\30 +x-100\\\\x=100+30\\\\x = 130[/tex]
Hence, the minimum qualifying score to join the genius society is 130.

If you invest $5,000 at 1.8 percent for 5 years, compounded semi-annually, what is the amount in the account at the end of 5 years?
$5,450
$5,469
$5,470
$5,560
Answer: B: $5,469
Step-by-step explanation:
Here is the formula for compound interest:
CI = P(1 + r/n)^rt, where n is the number of times the interest is compounded in a year. In our case, since there is semi annual compounding, n = 2.
The rest of the formula can be filled out:
CI = 5000(1 + 0.018/2)^(5x2)
CI = 5000(1.009)^10
CI = 5000(
.: CI ≅ $5468.67
Thus the answer is B.

How many ml of a 50% sugar solution must be mixed with 10 ml of a 68% sugar solution to make a 62% solution?
Answer:
well first we need to see the total percent of sugar solution there is.
So first we need to add 50%+68%=118%/200%
so now 62%/100% needs translated to /200%.
We get 124%/200% Now 50%/100%=100%/200% 68%/100%=136%/200%

1. What base ten number does 21603 seven
represent?
2. Express the number 77 ten in base number
The 21603 base seven and 77 base ten are number bases
21603 base seven represents 5442 in base ten77 base ten represents 130 in base sevenHow to rewrite the numbers
1. What base ten number does 21603 seven represent?
This is represented as:
[tex]21603_7[/tex]
To convert to base 10, we have:
[tex]21603_7 = 2 * 7^4 + 1 * 7^3 + 6 * 7^2 + 0 * 7^1 + 3 * 7^0[/tex]
Evaluate the sum and the exponents
[tex]21603_7 = 5442[/tex]
Hence, 21603 base seven represents 5442 in base ten
2. Express the number 77 ten in base number
This is represented as:
[tex]77_{10}[/tex]
To convert to a base number (say base 7), we have:
77/ 7 = 10 R 0
10/7 = 1 R 3
1/7 = 0 R 1
Hence, 77 base ten represents 130 in base seven
