Don bought 3/4 of a pound of jelly beans and ate 5/8 of the jelly beans before he got home. How much candy was left?
Answer:
CAN YOU MARK ME BRAINLIEST ??
The answer is 1/8 candy left!!
Step-by-step explanation:
3/4=6/8 because x2.
6/8-5/8= 1/8
Answer:
1/8 of the jelly beans
Step-by-step explanation:
You need to create a common denominator between the two fractions. Since both 4 and 8 go into 8, that will be the common denominator. To get 4 to 8, you have to multiply by 2, so to even it out you multiply the numerator by 2(3x2) which equals 6. Now the first fraction is 6/8 and the second is still 5/8. If he ate 5/8 of 6/8 jelly beans, you need to subtract. 6/8 minus 5/8 is 1/8

Answer:
21
Step-by-step explanation:
Let the three consecutive integers be;
x , x + 1 and x + 2:
The sum of squares of the two smaller numbers:
The two smaller numbers are x and x+ 1
Sum of their squares:
x² + (x+1)²;
x² + x² + 2x + 1 = 2x² + 2x + 1
It is 45 more than the square of the larger number:
Larger number = x + 2
(x+2)² = x² + 4x + 4
45 more;
x² + 4x + 4 + 45 = x² + 4x + 49
Both are equal:
2x² + 2x + 1 = x² + 4x + 49
2x² - x² + 2x - 4x + 1 - 49 = 0
x² - 2x - 48 = 0
x² - 6x + 8x - 48 = 0
x(x - 6) + 8(x - 6) = 0
(x + 8)(x-6) = 0
x + 8 = 0 or x - 6 = 0
x = -8 or x = 6
We choose x = 6 because it makes the solution true as a positive integer
Sum of the three numbers:
x + x + 1 + x + 2 = 6 + 6 + 1 + 6 + 2 = 21

If you want to got to Gurnee Mills and it's 1 hour from your house but you have to wait an extra hour how many hours did t take you to get to Gurnee Mills?
A.
2 hours
B.
1 hr. 30 min
Answer:
the answer is a i believe
Step-by-step explanation:
The solution is Option A.
The total time it took to travel from the house to Gurnee Mills is given by the equation A = 2 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total time to travel from the house to Gurnee Mills be A
Now , the equation will be
The time it took to travel to Gurnee Mills without waiting = 1 hour
The waiting time before travel = 1 hour
So , the total time to travel from the house to Gurnee Mills A = time it took to travel to Gurnee Mills without waiting + waiting time before travel
Substituting the values in the equation , we get
The total time to travel from the house to Gurnee Mills A = 1 + 1
On simplifying the equation , we get
The total time to travel from the house to Gurnee Mills A = 2 hours
Therefore , the value of A is 2 hours
Hence , the the total time is 2 hours

if xy=5 and x square +y square =25 ,then (x+y)square
Answer:
(x + y)² = 35
Step-by-step explanation:
The expansion of
(x + y)² = x² + 2xy + y²
= x² + y² + 2xy ← substitute given values
= 25 + 2(5)
= 25 + 10
= 35
Answer:
35
Step-by-step explanation:
[tex]xy = 5 \\ \\ {x}^{2} + {y}^{2} = 25 \\ \\ \because \: {(x + y)}^{2} = {x}^{2} + {y}^{2} + 2xy\\ \\ \therefore {(x + y)}^{2} = 25 + 2 \times 5 \\ \\ \therefore {(x + y)}^{2} = 25 + 10 \\ \\ \huge \red{ \boxed{\therefore {(x + y)}^{2} = 35}}[/tex]

#1: what percent of 78 is 16?
#2: what is 79% of 55?
Answer:
1. 487.5%
2. 43.45
Step-by-step explanation:
Remember the formula for a proportion: ((part)/(whole)) = ((percent)/(100))
1.
The part is given, 78, and the whole is given, 16.
Set up a porportion:
78/16 = percent/ 100
Simplify:
39/8 = percent /100
Cross products
39/8 = percent/100
8percent = 3900
Inverse operations
8percent = 3900
/8 /8
percent = 487.5
487.5%
2.
The percent is given, and the whole is given.
Set up a proportion:
part/55 = 79/100
Cross products
part/55 = 79/100
100part = 4345
Inverse operations
100part = 4345
/100 /100
part = 43.45
43.45

Is the calculation for the question: Write an expression for the calculation. Double the number 6 and then subtract 36 divided by 12. Is the answer 6 x 2 - 36 ÷ 12?
Answer:
Yes
Step-by-step explanation:
Yes the answer is 6 x 2 - 36 ÷ 12 and it is correct. Although you could change this arithmetic expression by adding parenthesis to make it easier to read and know which operations come first, like so...
(6 x 2) - (36 ÷ 12)
This would make it easier to see that the 6x2 must be done first and then the 36/12 before doing the subtraction.

6 x (2-8) + 4
Answer:
-32
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
In Solving This You will Need To;
*First You Open The Bracket Which is
6×(2-8)+4
6×2-8+4
*So after this you will multiply the 6 by the 2 which is going to be;
12-8+4
*So after you have multiplied 6 by 2 you can choose to subtract the 8 from the 12 or you can also choose to add the -8+4 either way you choose you're going to arrive at the same answer. So I choose to subtract 8 from the 12 so it's going to be;
4+4
Then you add the four plus 4 so the final answer will be 8
(If I chose to add the -8+4 it would have been -4 so 12-4 would have also given me 8 so any step is acceptable)
