−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 WRONG
- 5x - 25 = 78
- 5x - 25 + 25 = 78 + 25
- 5x = 103
x = - 103/5
x = - 20,6
Answer:
Step-by-step explanation:
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 <== this is where the error was made.
Step 2: −5x = 53
Step 3: = −5x/−5=53/−5
Step 4: x = −53/5
Right steps:
−5x − 25 = 78
Step 1: −5x − 25 + 25 = 78 + 25
Step 2: −5x = 103
Step 3: −5x/−5 = 103/−5
Step 4: x = 103
Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.

Answer:
Write the absolute value equations in the form
x−b
=c (where b is a number and c can be either number or an expression) that have the following solution sets.
Chapter Reference
a
Two solutions: x=2, x=14.
Step-by-step explanation:
The absolute value equations in the form |x-b|=c is 6.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
Two solutions are x=2 and x=14
Now,
To write an absolute value equation that has these solutions, we need to find a common value of b and c that satisfy the property above. One possible way to do this is to find the midpoint and the distance between the two solutions. The midpoint is the average of the two solutions, and the distance is half of their difference. The midpoint will be the value of b, and the distance will be the value of c.
Using this method, we get:
b = (2 + 14) / 2 = 8
c = (14 - 2) / 2 = 6
Therefore, by the given equation the answer will be 6

Use the diagram below, if m∠AEC=41°, find each angle measure
Answer:
[14] 139
[15] 90
[16] 41
[17] 49
[18] 139
[19] 131
Step-by-step explanation:
[14] Since m ∠ CEB is vertical with m ∠ AED = 139
[15] Knowing that m ∠FBD = 90 degree then m ∠ CEF = 90 degree
[16] Since m ∠ DEB is vertical to m ∠ADC Thus answer = 41
Note: vertical angles are angles opposite each other where two lines cross.
[17] Since m ∠ FED = 90 degree and m ∠ DEB = 41 then 90 - 41 = 49
[18] To Find m ∠CEB we have to subtract from m ∠ DEB
180 - 41 = 139
[19] Knowing that m ∠ FED = 90 degree and m ∠DEB = 41
Then m ∠ AEF = 90 +41=131

Ryan has a bag that contains strawberry chews, cherry chews, and watermelon chews. He performs an experiment. Ryan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ryan performs the experiment 37 times. The results are shown below:
A strawberry chew was selected 8 times.
A cherry chew was selected 12 times.
A watermelon chew was selected 17 times.
Based on these results, express the probability that the next chew Ryan removes from the bag will be cherry or watermelon as a decimal to the nearest hundredth.
Answer:
32.43%
Step-by-step explanation:
Since there are a total of 37 tests and cherry was selected 12 times, the probability would be 12/37.
12(100/37)
32.43
The probability that it will be a cherry or watermelon is; P(Cherry or water melon) = (12 + 17)/37 = 0.51
How to find the Probability?
We are told that Ryan performs the experiment a total of 37 times.
From the experiment he got;
Strawberry = 8 times
Cherry = 12 times
Watermelon = 17 times
Thus, probability that it will be a cherry or watermelon is;
P(Cherry or water melon) = (12 + 17)/37 = 0.51

Which scenarios can be represented by a ratio of 4 : 5 ?
There are 8 apples and 10 oranges in a basket. In this scenario, we can see that ratio of apples to oranges is 4:5.
What is the ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
A ratio is a fraction that may compare part to whole or part to part. For example, suppose in a class, the ratio of boys to girls is 4 to 5. It means that the number of boys divided by the number of girls is a fraction that, in its simplest form, equals 4 over 5.
Same as there are 8 apples and 10 oranges in a basket. this is also represented perfectly in terms of ratio.
Therefore, In a basket, there are 10 oranges and 8 apples. We can observe that the ratio of apples to oranges in this situation is 4:5.

A truck drove 208 miles on 5 gallons of gas. How far should it be able to go on a full, 11-gallon tank?
Answer:
457.6
Step-by-step explanation:
if he drove 208 on 5 gallons, 208/5 =41.6 miles per gallon. 41.6*11= 457.6
Answer:
457.6 miles
Step-by-step explanation:
So 208 miles equals 5 gallons so if you add 208 two times you will already have used 10 gallons and that equals 416 miles so far. So now you have to divide 208 by 5 and that equals 41.6 so 416 plus 41.6 equals 457.6 miles

Number 6 is
Step-by-step explanation:
Number 1: He needs 5x3 to get 15 balloons, but since he need more than provided, he needs one more pack.
Number 2: He played 2 rounds, and each round got 4 points, 4x2=8.
Number 4: If she had 8x8=64, and subtracted 10, she has 54.
Number 6: So you should make the fractions improper fractions, (fractions that have a numerator thats more than the denominator) so 2 1/4 = 9/4 and 3 1/4 = 13/4 and then multiply 13 x 9= 117 and then 4x4= 16 so you have 117/16 and then when you simplify it you get: 7 5/16

3. Which two integers are 7 units away from the number 5 on a number line?
A. -2 and 2
B. -2 and 7
C. -7 and 7
D. -2 and 12
Answer:
2B
3D
Step-by-step explanation:
2A is
a/b + -a/-b = a/b + a/b = 2a/b
this is NOT 0/0. you can't add numerator and denominator. when you have the same denominator, you can only add the numerator.
and don't forget : -×- and -/- are both + !
2B
you do not multiply anything. you ADD (but again NOT the denominators) !
and +×- or +/- = - !
overall this this adding a negative number to the same positive number. the result : always 0
2C
cannot be added like that. first you would have to bring both to a common denominator. but then you ADD !
2D
very similar to 2C.
3
5 + 7 = 12
5 - 6 = -2
these are the 2 integers 7 units away from 5.

After 5 years, $40,000 deposited in a savings account with simple interest had earned $26,000 in interest. What was the interest rate?
Answer: The answer is 13% interest rate.
Step-by-step explanation: first divide the interest money by the number of years (or months it doesn't matter) which would get you 5200 then you would divide 5200 by the amount of money deposited into the bank (40,000) which should give you 0.13 or 13%
26,000 / 5 = 5,200
5,200 / 40,000 = 0.13 = 13%
