Treena flew home to visit her family for
Thanksgiving and checked two suitcases.
If their combined weight was 71.5 pounds
and one bag weighed 47,8 pounds, find the
weight of the other bag,
x + y = 71.5
x = 47.8
y = 71.5 - 47.8
71.5 - 47.8 = 23.7
y = 23.7 pounds

Triangle E B C is shown with its exterior angles. Line E C extends through point F. Line C B extends through point A. Line B E extends through point D. Which statements regarding the diagram of ΔEBC are true? Select three options. ∠BEC is an exterior angle. ∠DEC is an exterior angle. ∠ABE and ∠EBC are supplementary angles. ∠BCF and ∠DEC are supplementary angles. ∠BEC is a remote interior angle to exterior ∠BCF.
Answer:
2, 3, 5 are true statements
Step-by-step explanation:
A diagram of the geometry is helpful. Our understanding of your description is shown in the first attachment. The second attachment shows how the various angles relate to each other. An exterior angle and its adjacent interior angle are a linear pair, so are supplementary.

1. BEC is an exterior angle -- False, it is an interior angle
2. DEC is an exterior angle -- True
3. ABE and EBC are supplementary -- True, they are a linear pair
4. BCF and DEC are supplementary -- False, they are unrelated exterior angles

3. correct
4. [tex]a^{8}b^{10}c^{15}[/tex]
Step-by-step explanation:
When dividing a monomial by another monomial, we divide the coefficients and apply the quotient law of exponents, x m ÷ x n = x m – n to the variables. If both the monomials have negative coefficients, the negative signs cancel out and the answer so obtained will be having a positive coefficient only.
For example, the binomial 2x +4 can be multiplied by the monomial 4x so that (2x) (4x) equals 8x2 and 4·4x equals 16x, using the distributive property. Therefore, (2x +4) (4x) equals 8x2 + 16x.Mar 15, 2016
Use the Quotient Property. When we divide monomials with more than one variable, we write one fraction for each variable. Use fraction multiplication. Simplify and use the Quotient Property.
The figure shows 3 semicircles and a right-angled triangle, Find the total area of the shaded parts. (Take a = 3.14)
Answer:
A semicircle is drawn with AC as diameter. If AB = BC = 7 cm, find the area of the shaded region. Take π = 22/7. 25. A circular field has perimeter 660 m.
Using the formula for area of circle and right angled triangle, we find that area of shaded region is 96[tex]cm^2[/tex].
Area of circle = [tex]\pi r^2[/tex]
where, r is the radius of circle.
Area of right angled triangle = [tex]\frac{1}{2} * base *height[/tex]
The area of shaded region is given by =
= area of semicircle with AB as diameter + area of semicircle with BC as diameter + area of triangle ABC - area of semicircle with AC as diameter
Now,
area of semicircle with AB as diameter =
AB = diameter = 12cm
radius = 6 cm
area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 6^2 = 56.52[/tex]
area of semicircle with BC as diameter =
BC = diameter = 16cm
radius = 8 cm
area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 8^2 = 100.48[/tex]
area of semicircle with AC as diameter =
AC = diameter = 20cm
radius = 10 cm
area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 10^2 =157[/tex]
area of triangle ABC =
AB = base = 12cm
BC = perpendicular = 16 cm
area(ABC) = [tex]\frac{1}{2}*12*16 = 96[/tex]
The area of shaded region is given by = 56.52 + 100.48 + 96 - 157 = 96[tex]cm^2[/tex]

Factors = 2 , 10 {2*10 = 20 & 2+10 = 12}
x² +12x + 20 = x² + 2x + 10x + 20 {Split the middle terms using the factors}

There are 9 students in a service club. The club is making gift baskets for children in a hospital. Each club member donated 4 children’s books for the baskets. Each club member also donated an equal number of toys. A total of 63 items were collected for the baskets. Which linear equation can you use to find how many toys each club member donated?
Answer:
9x + 36 = 63
Step-by-step explanation:
Let x represent the number of toys that each club member donated.
There are 9 students in a service club.
If each club member donated 4 children's books for the baskets, it means that the total number of books donated by the club members would be
9 × 4 = 36
If each club member also donated an equal number of toys. It means that the total number of toys donated by the club members would be
9 × x = 9x
A total of 63 items were collected for the baskets. Therefore, the linear equation that you can use to find how many toys each club member donated would be
9x + 36 = 63

F(x)=(x-6)2(x+2)2
Determine number of roots
Answer:
(x - 6)^2 = 0 or (x + 2)^2 = 0
Take the square root of both sides:
x - 6 = 0 or (x + 2)^2 = 0
Add 6 to both sides:
x = 6 or (x + 2)^2 = 0
Take the square root of both sides:
x = 6 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 6 or x = -2
Step-by-step explanation: the answer is x= 6 or = -2

the sum of ages of Jamal and his father is 40 years.After 4 years,the age of the father will be triple the age of his son.Find the age of Kamal and his father
Answer:
The age of Jamal is 8 years.
And the age of his father is 32 years.
Step-by-step explanation:
=> let the age of Jamal be x and his father's age be y
=> so , A.T.Q ,
x+y = 40....i)
Find the value of y from here , that's y = 40-x .....
Now, After 4 years ,
=> 3(x+4) = (y+4)
=> 3x+12 = y+4
=> 3x+8 = y ...ii)
putting the value of y in equation ii)
=> 3x+8 = 40-x
=> 3x+x = 40-8
=> 4x = 32
=> x = 8
now ,
=> y = 40-x
=> y = 40-8
=> 32
Ju long has 6 guppies in his aquarium. This is 24% of the fish in the aquarium. How many fish are in Ju long's aquarium? Use an equation with a variable? Show your work.
Answer: 25
Step-by-step explanation:
Let x be the amount of fish in Ju Long's aquarium.

Janae and Jerome each have m marbles. Gwen has 4(m 2) marbles. John has 8m 4 marbles. If John has more marbles than Janae, Jerome, and Gwen combined, how many marbles might Janae and Jerome each have? Select each possible answer.
Janae and Jerome each have either 3, or 4 or 5 marbles. Option C, D and E are correct.
How do you calculate the value of integer m?Given that the number of marbles has:
Janae = m
Jerome = m
Gwen = 4(m+2)
John = 8m+4
John has more marbles than Janae, Jerome, and Gwen combined, So this can be written as,
[tex]8m+4 \geq m + m + 4(m+2)[/tex]
[tex]8m+4\geq 2m + 4m+8[/tex]
[tex]8m+4 \geq 6m+8[/tex]
[tex]2m\geq 4[/tex]
[tex]m\geq 2[/tex]
It means that the value of m is greater than 2, it can be 3, 4 or 5.
Hence we can conclude that Janae and Jerome each have either 3, or 4 or 5 marbles. Options C, D and E are correct.
