Answer:
see below
Step-by-step explanation:
Let f = number of friends
all but one friend got 6 pieces and 1 friend got 2 for a total of 50 pieces
6(f-1) + 2 = 50
Subtract 2 from each side
6(f-1) +2-2 = 50-2
6(f-1) = 48
Divide by 6
6(f-1)/6 = 48/6
f-1 = 8
Add 1 to each side
f-1+1=8+1
f=9

the product of 5 and a number K is less than 60
Answer:
11
Step-by-step explanation:
The required inequality would be 5k < 60 which represents the product of 5, and the number K is less than 60.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To determine the product of 5 and a number K is less than 60
Here the word "Product" represents multiplication,
So the product of 5 and a number K would be 5×K = 5K
As per the given condition,
So the required inequality would be 5k < 60
Therefore, the required inequality would be 5k < 60 which represents the product of 5, and the number K is less than 60.

given : 2x+8=5x-13; prove x=7
Answer:
True
Step-by-step explanation:
The left side 22 is equal to the right side 22 , which means that the given statement is always true.
Step-by-step explanation:
If we want to prove that x is equal to seven, we should first solve the equation for x so:
2x + 8 = 5x - 13
We should first add 13 on both sides and subtract 2x from both sides:
2x + 8 + 13 - 2x = 5x - 13 + 13 - 2x
21 = 3x
We can then divide both sides by 3 to get:
x = 7

Step-by-step explanation:
School was starting and James had $300 to spend on clothes. He bought a pair of shoes for$62.50, 3 shirts for $17.25 each, and 5 pairs of jeans at $27.75 each. How much change will James get back? *
Answer:
$47
Step-by-step explanation:
Multiply the quantities of each by the prices, then add it all together to find total spent. Subtract total spent from what he has to spend to find the change:
3 shirts x 17.25 = 51.75
5 jeans x 27.75 = 138.75
Total pent : 62.50 + 51.75 + 138.75 = $253.00
Change : 300 - 253 = $47.00
SOLVE QUESTION 3 PART A AND B !! WILL GIVE BRAINLIST ..
Answer:
28π, reasonable
Step-by-step explanation:
A. Circumference is 2πr (or dπ), so we plug in 14 for r
this leaves us with 2π14, in which the 2 and 14 can multiply, so we get 28π
B. if we plug 28π into the calculator, you'll get 87.96, so 85cm is reasonable

if I have a garden that's 10 yards and I want to grow a plant that's 2.5 yards how many of that can I plant
Answer:
4
Step-by-step explanation:
2.5y x 4 = 10y
Hope This Helps
<3
Answer: 4 plants.
Step-by-step explanation:
In the case that these measurements are of length, the plant being 2.5 yards and the total length of the garden area being 10 yards, the most simple way to solve this is to find how many 2.5 yard sections of this garden are in the given plot.
[tex]10/2.5 =4[/tex]
When 10 is divided by 2.5 you receive the answer "4". You can fit 4 plants within the garden. 2.5 x 2 is 5, and 5 x 2 is 10. 2 x 2, therefore, would give you the answer 4.
I hope this explanation helped you understand the question and the answer better.

what is the total cost of $16 if you include 5% GST and 20% tip
Answer:$20
Step-by-step explanation:
16 divided by 10 = 1.6 (10%)
1.6 times 2 = 3.2 (20%)
16 + 3.2 = 19.2
1.6 divided by 2 = 0.8 (5%)
19.2 + 0.8 = 20$

What is percentage of a number?The percentage of a number represents a portion or fraction of the whole number expressed as a fraction of 100. It is often used to describe a proportion or rate out of 100.
To calculate the percentage of a number, you typically multiply the number by the desired percentage as a decimal or fraction. The result represents the portion or fraction of the number expressed as a percentage.
The formula for calculating the percentage of a number is:
Percentage = (Number * Percentage Value) / 100.
Substituting the values into the formula above;
percentage = (9 / 12) * 100
percentage = (3/4) * 100
percentage = 0.75 * 100
Percentage = 75%
