Answer:
Both expression equals 5 when substituting 2 for x, because the expressions are equivalent.
Step-by-step explanation:
Given the expressions:
(1/2)x + 4
x + 6 - (1/2)x - 2
Substituting 2 for x in the equation :
(1/2)x + 4
x = 5
(1/2)2 + 4
2/2 + 4
1 + 4
= 5
x + 6 - (1/2)x - 2
Substituting 2 for x
2 + 6 - (1/2)2 - 2
8 - 2/2 - 2
8 - 1 - 2
= 5

15/5 = 3, 21/7 = 3 -- scale factor is 1/3 since he must divide by 3 to get the side lengths for the photo card
B.
Area = width*length, and scale factor is 5. Therefore, the new width is (15*5) and the new length is (21*5), so the new area is 15*5*21*5 = 15*21*5² = 15*21*25 = 315*25 = 7875 in²

Solve the following equation for x.
−13−4x−13x=−14+15x
Answers
Answer:
x=1/32
Step-by-step explanation:
-13-4x-13x=-14+15x
first, combine the like terms.
add -4x and -13x
-13-17x=-14+15x
now, add 13 to both sides
-17x=-1+15x
subtract 15x from both sides
-32x=-1
divide by -32
x=-1/-32
Simplify
x=1/32
Hope this helps!
Answer:
x = 0.84375
Step-by-step explanation:
-13 - 4x - 13x = 14 + 15x
-13 - 17x = 14 + 15x
-13 - 17x + 17x = 14 + 15x + 17x
-13 = 14 + 32x
-13 - 14 = 32x
-27 = 32x
-27 / -32 = 32x / 32
0.84375 = x

The largest Prime number less than 100 is ?
Answers
Answer: 97
Step-by-step explanation: The first 25 prime numbers (all the prime numbers less than 100) are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 (sequence) just if you need all the primes
The largest prime number less than 100 is 97 by using the definition of prime number and examine the prime numbers that are smaller than 100.
To find the largest prime number less than 100, to examine the prime numbers that are smaller than 100.
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
Starting from 99 and moving downwards, check each number for divisibility by smaller numbers.
Any number that has divisors other than 1 and itself is not prime.
99 is not a prime number as it has more than one factors.
99 = 1, 3, 9, 11, 33, 99.
98 is not a prime number as it has more than one factors.
98 = 1, 2, 4, ........, 98.
97 is a prime number as it has more than one factors.
97 = 1, 97.
By doing this process, eventually reach 97, which is the largest prime number less than 100.

You randomly select one card from a 52-card deckFind the probability of selecting the eight of spades or the seven of hearts
Answers
→ Probablity of getting the 8 spades = 1/52
→ Probablity of getting the 7 hearts = 1/52
Both are mutually exclusive event's.So,
⇒ Probablity of getting 7 hearts or 8 spades = Probablity of getting the 7 hearts + Probablity of getting the 8 spades
⇒ Probablity of getting 7 hearts or 8 spades = 1/52 + 1/52
⇒ Probablity of getting 7 hearts or 8 spades = 2/52
⇒ Probablity of getting 7 hearts or 8 spades = 1/26
The probability of selecting the eight of spades or the seven of hearts is 1/26.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of cards = 52
Number of eight of spades in the deck of cards = 1
Number of seven of hearts in the deck of cards = 1
The probability of selecting the eight of spades or the seven of hearts.
= 1/52 + 1/52
= 2/52
= 1/26
Thus,
The probability of selecting the eight of spades or the seven of hearts is 1/26.

Answer:
1). Area = 37 cm²
2). Area = 120 cm²
Step-by-step explanation:
Figures in the picture attached are the examples of composite figures.
1). Area of the composite figure = Area of rectangle A + Area of rectangle B
Since area of rectangle = Length × width
Area of rectangle A = 8 × 2 = 16 cm²
Area of rectangle B = 3 × 7 = 21 cm²
Area of the composite figure = 16 + 21 = 37 cm²
2). Area of the composite figure = Area of C + Area of D
= (3×4) + (9×12)
= 12 + 108
= 120 cm²

Step-by-step explanation:
Given the following probability
P(A) = 0.4 P(B) = 0.6
a) P(A and B) =P(A)P(B) {Independent)
P(A and B) = 0.4×0.6
P(A and B) = 0.24
b) Given P(A | B) = 0.5, this is a conditional probability
If P(A | B) = P(A and B)/P(B)
Since If P(A | B) = 0.5
0.5 = P(A and B)/P(B)
P(A and B) = 0.5(P(B)
P(A and B) = 0.5(0.6)
P(A and B) = 0.3

solve the equation: the booster club of the baseball team bought pizza to sell at a concession stand. the school donated three pies to the sale. each pie was then cut into 8 pieces and sold . there were a total of 64 pieces to sell. how many pies did the booster club purchase
Answers
Answer:
they bought 5 pies
Step-by-step explanation:
.................
Five pies were bought by the booster club of the baseball team.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Three pies were provided for sale by the school. After that, each pie was divided into 8 pieces and sold. 64 pieces in all were available for purchase.
Let "p" be the number of pies the booster club purchased.
The school donated 3 pies, so the booster club purchased a total of p + 3 pies.
Each pie was cut into 8 pieces, so there were a total of (p + 3) × 8 = 64 pieces to sell.
This equation can be simplified to p + 3 = 8, or p = 5.
Therefore, there was a booster club that purchased 5 pies.
