Write a story that represents the math problem 2/6 times 3/4
Answers
There is only 3/4 of a pie left. Two families decide to split the pie. There are 6 kids total, and they decide that each kid should get a sixth of what's left of the pie. One family has 2 kids, so how much pie will they get?
So 2/6 of 3/4 is 1/4 or .25
step by step: rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 1/4*t6-(-4)=0
simplify 1/4
((1/4•t) - 6) - -4 =0
subtracting a whole from a fraction. rewrite the whole as a fraction using 4 as the denominator :
6 = 6/1 = 6•4/4
equivalent fraction: the fraction thus generated looks different but has the same value as the whole.
common denominator: the equivalent fraction and the other fraction involved in the calculation share the same denominator.
adding up the two equivalent fractions
add the two equivalent fractions which now have a common denominator.
combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
t - (6•4)/4 = t - 24/4
(t - 24) - -4 = 0
subtracting a whole from a fraction
rewrite the whole as a fraction using 4 as a denominator:
-4 = -4/1 = -4•4 / 4
adding up the two equivalent fractions.
t - 8/4 =0
when a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now, to get rid of the denominator. Tiger multiples both sides of the equation by the denominator.
here's how:
t-8 • 4 = 0 • 4
Now, on the left hand said, the 4 cancels out the denominator while on the right side, zero times anything is still zero.
The equation now takes the shape
t-8=0
solve t-8=0
add 8 to both sides of the equation:
t = 8
that's how you get the answer.

X + 3 +2 > 15
Subtract 2 from both sides
X + 3 > 13
Subtract 3 from both sides ;)
X > 10
Answer:10
Step-by-step explanation:
X + 3 +2 > 15 would be the equation
First we Subtract 2 from both sides,which gives us this.
X + 3 > 13
Then we Subtract 3 from both sides
which gives us an answer of
X > 10
which we can also write as 10
Adrian and Nicky earn weekly allowances doing chores over the summer.
•Adrian’s mom pays him $5 each week.
•Nicky’s dad pays her $20 at the beginning of the summer and $3 each week.
Give at least one difference between the graphs and the equations for these 2 situations.
Answers
Answer:
To start off, we have a two linear functions to deal with here.
The first starts off at (0,0) and goes linearly up $5 per 1 week or $1.4 per day
The second one starts off at (0,20) and goes linearly up $3 per 1 week or $2.333... per day.
So, the first difference is that Nicky's graph starts higher than Adrian's.
And the second Difference is that Nicky's graph has a lower rate of change than Adrians.

a. 80%
b.-20%
c.24%
d.-5%
e. $210
Step-by-step explanation:
Step-by-step explanation:
a) $153 - $85 = $68
68 ÷ 85 = 0.8 × 100 = 80
80% increased.
80% of $85 is $68
b) $340 - $272 = $68
68 ÷ 340 = 0.2 × 100 = 20
20% decreased
20% of $340 is $68
c)78,616 - 63,400 = 15,216
15,216 ÷ 63,400 = 0.24 × 100 = 24
24% increased
24% of 63,400 is 15,216
d)2580 - 2451 = 129
129 ÷ 2580 = 0.05 × 100 = 5
5% decreased
5% of 2580 is 129
e) 75% of $120
75 ÷ 100 = 0.75 × 120 = 90
120 + 90 = 210
she sell it for $210

A group of children go see a movie. Tickets are $8 each and they split a large popcorn. They spend a total of $34.50.
Please please please explain how you got the answer.
Answers
Answer:
Movie tickets cost $5 for children, $8 for adults and $4 for seniors.
The theater earned $1890 in a day. Five times as many adults attended as seniors.
Twice as many children attended as seniors.
Set up and solve a system of equations, to find how many of each type of ticket was sold.
"The theater earned $1890 in a day."
5c + 8a + 4s = 1890
"Five times as many adults attended as seniors."
a = 5s
Twice as many children attended as seniors."
c = 2s
5c + 8a + 4s = 1890
replace c with 2s; replace a with 5s
5(2s) + 8(5s) + 4s = 1890
10s + 40s + 4s = 1890
54s = 1890
s = 1890/54
s = 35 Seniors
then
a = 5(35)
a = 175 adults
and
c = 2(35)
c = 70 children
Step-by-step explanation:
Check solution
70(5) + 175(8) + 35(4) =
350 + 1400 + 140 = 1890; confirms our solutions

[tex]\frac{(x- 3)(x+3)}{(y - 5)(y+5)} * \frac{3y(y - 5)}{2x(x - 3)} + \frac{3 - 1.5y}{y + 5}[/tex]
x - 3 cancels out:
[tex]\frac{(x+3)}{(y - 5)(y+5)} * \frac{3y(y - 5)}{2x} + \frac{3 - 1.5y}{y + 5}[/tex]
y - 5 cancels out
[tex]\frac{x+3}{y+5} * \frac{3y}{2x} + \frac{3 - 1.5y}{y + 5}[/tex]
[tex]\frac{3y(x+3)}{2x(y+5)} + \frac{3 - 1.5y}{y + 5}[/tex]
Take L.C.M

Hence:
[tex]\frac{x^2 - 9}{y^2 - 25} / \frac{2x^2 - 6x}{3y^2 - 15y} + \frac{3 - 1.5y}{y + 5} = \frac{3(3y + 2x)}{2x(y+5)}[/tex] If [tex]x \ne 0 \ \ or\ y \ne 0[/tex]

-2y + 6 = -12 (subtract 6 from both sides to get the y-term alone)
-2y = -18 (divide both sides by -2 to get y alone)

Answer:
32 Inches
Step-by-step explanation:
First, split arrow into triangle and rectangle
----------------------------------------------------------------
Rectangle:
Area=5x4
=20
--------------------------------------------------------------
Triangle:
Area=6x2
=12
-----------------------------------------------------------------
Add both shapes areas together
to find total

Total=32 Inches
The solution is : 26 sq.Inches area needs to be painted for 1 arrow.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
