Equivalent or Not?
Sarah thinks that the following
expressions are equivalent:
2x + 3 = x/2 + 4
Is she correct? If so, prove that these
two expressions are equivalent. If not,
explain what errors she made.
Answer:
equivalentStep-by-step explanation:
2x + 3 = x/2 + 4
2x - x/2 = 4 - 3
3x/2 = 1
x = 1 (2) / 3
x = 2/3
substitute the value of x=2/3 back into the equation:
2(2/3) + 3 = (2/3)/2 + 4
4/3 + 3 = 1/3 + 4

away at college. It simply reads
SEND
MORE
MONEY
The father is slightly upset that this is all his son
wrote but noticed something interesting. If each
letter is replaced with a single and unique digit, it
would make a true addition statement. The father
replies that he would send money if his son could
figure out what digit each letter would represent.
Answer:
S = 9, E = 5, N = 6, D = 7, M = 1, O = 0, R = 8, Y = 2
Step-by-step explanation:
The given letters are;
SEND
MORE
MONEY
If we are to add the first two words to get the third word, then we have;
SEND + MORE = MONEY
Where, the letters are unique digits
The maximum value of M = 1, because, the two words are in thousands and their sum is in tens of thousands, they can make up to only a 10
Therefore, S = 9
O = 0
D + E = 10 + Y
1 + N + R = 10 + E
1 + E = N
∴ 1 + N + R = 10 + E gives;
1 + 1 + E + R = 10 + E
R = 10 + E - (1 + 1 + E) = 8
R = 8
We have;
9 XXX + 108X = 10XXX
From 1 + N + R = 10 + E, we have;
1 + N + 8 = 10 + E
END + RE = NEY
E(1 + E)D + 8E = (1 + E)EY
(1 + E)EY - E(1 + E)D = 8E
10 + Y - D = E
By trial and error, we have;
If Y = 2 and D = 3, we have E = 9 which is not unique
Y = 4 and D = 3, we have E = 11 which is a double digit
Y = 2 and D = 7, we have E = 5
∴ N = 6 which is unique
Trying the combination gives;
S = 9, E = 5, N = 6, D = 7, M = 1, O = 0, R = 8, Y = 2
SEND + MORE = MONEY → 9567 + 1085 = 10652 which is correct.

Answer:
p = 1.2
Step-by-step explanation:
The given equation is :
–4.6p – 6.3p + 3.9 = –9.18
Combining the like terms,
–4.6p – 6.3p = -9.18 - 3.9
−10.9p = −13.08
⇒ [tex]p=\dfrac{-13.08}{-10.9}\\\\p=1.2[/tex]

Round 685,135 to the nearest ten thousand.
Answer:
690,000
Step-by-step explanation:
The 8 is the ten thousands place- 685,135
If the number after the 8, (in this case 5) is 0-4, round to 8. If the number after the 8 is 5-9, round up to 9.
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 77 feet per second. The elevator for the miners descends 1313 feet per second. One day, the equipment elevator begins to descend. After 2929 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 1616 seconds? At that time, which elevator is deeper?
Answer:
The position of the equipment elevator is 315 feet deep.
The position of the elevator of the miners is 208 feet deep.
At that time, the equipment elevator is deeper.
Step-by-step explanation:
Observation: Seems the numbers are doubled. 77 instead of 7; 1313 instead of 13; 2929 instead of 29; and 1616 instead of 16.
Hence, the question is:
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 7 feet per second. The elevator for the miners descends 13 feet per second. One day, the equipment elevator begins to descend. After 29 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 16 seconds? At that time, which elevator is deeper?
Step-by-step explanation:
From the question,
For the equipment elevator
Speed= 7 feet/second
For the elevator of the miners,
Speed= 13 feet/second
To determine the positions of each elevator relative to the surface, we will determine the distance each of the elevator descends.
From the formula
Speed= Distance / Time
Then,
Distance = Speed × Time
From the question,
The equipment elevator begins to descend and after 29 seconds, the elevator for the miners begins to descend. To determine the position of each elevator after another 16 seconds. That is, the equipment elevator descends for a total of (29+16) seconds and the elevator of the miners descends for 16 seconds.
For the equipment elevator
Speed= 7 feet/second
Time = 29 + 16 seconds = 45 seconds
From, Distance = Speed × Time
∴ Distance = 7 feet/second × 45 seconds
Distance = 315 feet
Hence, the position of the equipment elevator is 315 feet deep.
For the elevator of the miners
Speed = 13 feet/second
Time = 16 seconds
Distance = Speed × Time
∴ Distance = 13 feet/second × 16 seconds
Distance = 208 feet
Hence, the position of the elevator of the miners is 208 feet deep.
At that time the equipment elevator is deeper.

Lydia is having a party on Saturday. She decides to write a riddle on her invitations to describe her house number on Cypress Street. Use the clues below to find Lydia's address. My address is a 5−digit number. The tens digit is 6 less than 7. The thousands digit is twice the digit in the tens place. The hundreds digit is the greatest even number that is less than 10. The ones digit is the product of 5 and 1. The ten thousands digit is the difference between the hundreds digit and the ones digit. Lydia's address is Cypress Street.
Answer:
Lydia's address is Cypress Street is: 51823
Step-by-step explanation:
Represent the digit as ABCDE such that:
A = Ones
B = Tens
C = Hundred
D = Thousand
E = Ten Thousand
Analyzing the statements one after the other:
The tens digit is 6 less than 7.
[tex]B = 7 - 6[/tex]
[tex]B = 1[/tex]
The thousands digit is twice the digit in the tens place.
[tex]D = 2B[/tex]
[tex]D = 2 * 1[/tex]
[tex]D = 2[/tex]
The hundreds digit is the greatest even number that is less than 10.
[tex]C = 8[/tex]
The ones digit is the product of 5 and 1.
[tex]A = 5 * 1[/tex]
[tex]A = 5[/tex]
The ten thousands digit is the difference between the hundreds digit and the ones digit.
[tex]E = C - A[/tex]
[tex]E = 8 - 5[/tex]
[tex]E = 3[/tex]
Lydia's address is Cypress Street is: 51823

1. What is the surface area of this rectangular prism?
A. 16 square units
B. 32 square units
C. 48 square units
D. 64 square units
Answer:
I believe it is 64 ( I might be wrong)
Step-by-step explanation:
ok so in the picture, the top of the rectangle has 8 square units so that means that the base also has 8 square units and if you look at the sides they also have 8 square unit so:
8 x 4 = 32
and then in the picture, the face of the rectangle has 16 square units so the other face also has 16 square units so:
16 x 2 = 32 plus the 32 from the sides in 64

Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of the cows: Jo weighs 25 cows and gets an average weight of 1,350 pounds (stdev 50) Val weighs 100 cows and gets an average weight of 1,420 pounds (stdev 50) What is Jo's margin of error, rounded to the nearest whole number? (The formula is 1.96 straight x left parenthesis StdDev right parenthesis divided by square root of straight N)
Answer:
The value is [tex]E =19.6 [/tex]
Step-by-step explanation:
From the question we are told that
The mean of Jo cows is [tex]\= x_1 = 1350[/tex]
The standard deviation of Jo cow is [tex]s_1 = 50[/tex]
The mean of Val cows is [tex]\= x_2 = 1420 [/tex]
The standard deviation of Val cows is [tex]s_2 = 50[/tex]
The sample size for both Val and Jo is n = 25
Let assume that the level of significance is [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
Hence margin of error for Jo is
=> [tex]E = 1.96 * \frac{50}{\sqrt{25} }[/tex]
=> [tex]E =19.6 [/tex]
