Answer:
Their weights are:
Dorris = 5 lbs
Borris = 7 lbs
Morris = 9 lbs
Step-by-step explanation:
Let the weights of the frogs be:
Dorris = d
Borris = b
Morris = m
given:
d + b = 12 - - - (1)
b + m = 16 - - - (2)
d + m = 14 - - - (3)
from (3)
d + m = 14
m = 14 - d - - - (4)
putting the value of m into equation 2:
b + m = 16
b + (14 - d) = 16
b - d + 14 = 16
b - d = 16 - 14
b - d = 2
b = 2 + d - - - - (5)
putting the value of 'b' in equation 5 into equation (1)
d + b = 12 - - - (1)
where: b = 2 + d - - - (5)
∴ d + (2 + d ) = 12
d + d + 2 = 12
2d = 12 - 2
2d = 10
∴ d = 10 ÷ 2 = 5
d = 5
putting the value of 'd' into eqn (5)
b = 2 + d - - - - (5)
where d = 5
b = 2 + 5 = 7
b = 7 lbs
to find 'm', let us use eqn (3)
d + m = 14 - - - (3)
where d = 5
∴ 5 + m = 14
m = 14 - 5 = 9
m = 9 lbs
Therefore their weights are:
Dorris = 5 lbs
Borris = 7 lbs
Morris = 9 lbs
15 - 3x = 11 - 3x + 4
Answer:
Infinitely Many Solutions!
Steps I used to get the answer :
1. Cancel -3x−3x on both sides.
15=11+4
2. Simplify 11+4 to 15.
15=15
3. Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions!
Done by NeighborhoodDealer.
Answer:
Step-by-step explanation:
Solve for x:
15 - 3x = 11 - 3x + 4
Subtract 4 from both sides
15 - 3x - 4 = 11 - 3x + 4 - 4
11 - 3x = 11 - 3x
This equation has infinite solutions since both sides of the equation are equal.

Evan bought a bag of Skittles, ate 13 of them, then distributed them evenly into 4 bowls. If there are 64 Skittles in each bowl, how many were originally in the bag?
For the problem, find a variable and set up an equation, then solve.
I need this answer quick!
Answer:
There were 269 skittles in the bag originally.
Keywords: multiplication, addition
Step-by-step explanation:
Skittles ate by Evan = 13
No. of bowls = 4
No. of skittles in each bowl = 64
As the skittles are distributed evenly therefore,
Skittles in 4 bowls = 64*4
Skittles in 4 bowls = 256
Total skittles = Skittles in 4 bowls + skittles ate by Evan
Total skittles = 256 + 13
Total skittles = 269
There were 269 skittles in the bag originally.
Three fifths of the students in the cafeteria bought their lunch from the school. The rest brought their lunch from home. 27 of the students bought their lunch. Let t represent the total number of students in the cafeteria.
Answer:
45 students
Step-by-step explanation:
Three fifths of the students in the cafeteria bought their lunch from the school. The rest brought their lunch from home. 27 of the students bought their lunch. Let t represent the total number of students in the cafeteria.
We are to calculate the total number of students in the cafeteria.
Fraction of the students in the cafeteria that bought their lunch from the school = 3/5
Number of the students that bought their lunch = 27 students
The total number of students can be calculated as:
3/5 Of t = 27 students
3/5 × t = 27
Cross Multiply
3t/5 = 27
3t = 27 × 5
t = 27 × 5/3
t = 45 students
Therefore, the total number of students in the cafeteria = 45 students

A surfboard has an original price of $259. It is on sale for 55% off the original price.
Answer:
$116.55
Step-by-step explanation:
If original price= $259
And sale= 55% off original price
Then price after sale=(100%-55%) of $259
Working:
100%-55%=45% or [tex]\frac{45}{100}[/tex]
45% of $259 or [tex]\frac{45}{100}[/tex] x [tex]\frac{259}{1}[/tex]= $116.55

Which expressions are equivalent to − 90 − 60 w?
Answer:
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)
Using distributive property:
A : -30(3+2w) = -90 - 60w : equivalent to -90 - 60w
B : (-9-6w) ⋅ 10 = -90 - 60w : equivalent to -90 - 60w
C : -3(30 - 20w) = -90 + 60w : NOT equivalent to -90 - 60w
D : (6 + 4w)×15 = 90 + 60w : NOT equivalent to -90 - 60w
E : −20(4.5 + 3w) = - 90 - 60w : equivalent to -90 - 60w
SO THAT MEANS
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)

Bryan’s hockey team is purchasing jerseys. The company charges $250 for a one-time set-up fee and$23 for each printed jersey. Which expression represents the total cost of x number of jerseys for the team?
1) 23x
(2) 23x + 250
(3) 23 + 250x
(4) 23(x + 250)
Answer:
(2) 23x + 250
Step-by-step explanation:
We are given that
Company charges for one-time set up=$250
Charge for each printed jersey=$23
x=Number of jerseys for team
We have to find the expression which represents the total cost of x number of jerseys for the team.
Total cost of x jerseys printing=[tex]23\times x[/tex]
Total cost of x jerseys printing[tex]=23x[/tex]
Therefore,
Total cost of x number of jerseys for the team=250+23x
Hence, option (2) is true.
(2) 23x + 250
