Answer:
$12.50
Step-by-step explanation:
3/8 x 20/1 = 7.5
20 - 7.5 = 12.50
Jeff has $12.50 left after spending 3/8 of his money on lunch.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Jeff had $20.
Jeff spent 3/8 of his money on lunch.
To find the money he left after spending on lunch we get by subtracting three by eight from one.
1 - 3/8
=8-3/8
= 5/8 of his money left.
To find out how much money Jeff has left, we can multiply the remaining fraction by his initial amount of money:
Intitial amount is 20
The money left is 5/8.
Multiply five by eight with twenty.
Money left = (5/8) × $20
Five divided by eight times of twenty.
=100/8
When hundred is divided by eight we get twelve point five.
= $12.50
Therefore, Jeff has $12.50 left after spending 3/8 of his money on lunch.

Did any get the answer for puzzle 3 in Pythagorean Theorem Digital Escape!
The formula relations given by Pythagorean theorem is used to
determine the lengths and area of the given squares and triangles.
Responses:
1. Area of a is H: 25
2. Length of b is I: 5
3. Length of C is A: 7.94
4. Area of d is B: 35.73
Where can the Pythagorean theorem be used to find the lengths and areas of a figure?1. Given;
The area of the side squares are; 9 m² and 16 m²
According to Pythagorean theorem, we have;
Area of square a = 9 m² + 16 m² = 25 m²
Area of a is H: 252. b² = Area of side square a
Therefore;
b = √(25 m²) = 5 m
Length of b is I: 53. Given;
Area of the squares adjacent to the hypotenuse side and a leg are;
144 m² and 81 m² respectively
According to Pythagorean theorem, we have;
C² = 144 m² - 81 m² = 63 m²
C = √(63 m²) = √(9 × 7 m²) = 3·√7 m ≈ 7.94 m
Length of C is A: 7.944. Area of triangle d = [tex]\frac{1}{2}[/tex] × √(81 m²) × 7.94 m ≈ 35.73 m
Area of d is B: 35.73Learn more about Pythagorean theorem here:

find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x
16x + 8
10x + 4
12x + 4
8x + 2
Answer:
12x+4
Step-by-step explanation:
To find the perimeter of any shape you just have to take the sum of all the sides.
In this case you would write:
4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)
Now you just have to simplify the expression which would give you:
12x+4 (after collecting like terms)
So the final answer will be 12x+4

''Create your own word problem where the answer is ⅝. It should be solved using multiplication''
Answer:
Hi, your answer will be 5/8 x 2/8.
Step-by-step explanation:
When multiplying fractions, you are to do both the numerators and denominators. So, if you do 5/8 x 2/8, that would result as 10/16. When you simplify, that would be 10/16 divided by 2, which is 5/8.

Step-by-step explanation:
Nicole is half as old as Donald. The sum of their ages is 72.
How old is Nicole, in years?
Answer:
24 years
Step-by-step explanation:
let Donald's age be x
then Nicole's age would be 1/2 * x = x/2
now, x + x/2 = 72
3x/2 = 72
3x = 72*2
x = 144/3 = 48
Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.
The perimeter of an airplane ticket is 30 centimeters. The area is 50 square centimeters. What are the dimensions of the ticket?
Answer:
The length can be 5 and the width 10.
Step-by-step explanation:
perimeter is equal to 2L + 2W
area is equal to L * W
you get 2 equations:
30 = 2L + 2W
50 = L*W
we'll solve by substitution.
you can use either equation to solve for either variable.
we'll use the second equation to solve for L.
second equation is:
50 = L*W
divide both sides of this equation by W to get:
L = 50/W
we now have a value of L that we can substitute in the first equation which we can then use to solve for W.
the first equation is:
30 = 2L + 2W
replace L with 50/W to get:
30 = 2*(50/W) + 2W
simplify to get:
30 = 100/W + 2W
multiply both sides of this equation by W to get:
30W = 100 + 2W^2
subtract 30W from both sides of this equation to get:
2W^2 - 30W + 100 = 0
factor this equation to get:
(2W - 20) * (W - 5) = 0
solve for W to get:
W = 10 or W = 5
if W = 10, then use the equation of 50 = L*W to get L = 5
if W = 5, then use the equation of 50 = L*W to get L = 10
you have 2 possible solutions.
L = 5 and W = 10 or:
L = 10 and W = 5
both are plausible so we'll test them both out.
when L = 5 and W = 10:
the first equation becomes 2*5 + 2*10 = 10 + 20 = 30
the second equation becomes 5*10 = 50
both equations confirm that the solution of L = 5 and W = 10 is good.
when L = 10 andW = 5:
the first equation becomes 2*10 + 2*5 = 20 + 10 = 30
the second equation becomes 10*5 = 5
both equations confirm that the solution of L = 10 and W = 5 is good.
the ticket can have either:
a length of 5 and a width of 10 or:
a length of 10 and a width of 5.
since the length is usually longer than the width, you are free to choose that the ticket most likely has a length of 10 and a width of 5.
alternatively, you can simply say that the dimensions are 5 by 10 and let the recipient of that information determine which is the length and which is the width.
mathematically, the length can be 10 and the width 5 or the length can be 5 and the width 10.
Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?
GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO
Answer: hope this helps ♡
Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16
