Gina Needs To Pack 130 Pens, 50 Pencils And 20 Erasers Into Identical Gift Bags So That Each Item Is Equally Distributed Among The Gift Bags. (I) Find The Largest Number Of Gift Bags That Can Be Packed. (Ii) Find The Number Of Each Item In A Gift Bag.
Answer:
Step-by-step explanation:
I think the best way is to split up the erasers before you do anything. That would mean there were 20 gift bags in all
If you did that, then each gift bag would contain 2 pencils with 10 left over.
Further 130 pens would divide up into 6 pens in each gift bag with 10 pens left over.

A:-56
B:56
C:-48
D:48
Answer:
Hi there!
Your answer is:
A: -56
Step-by-step explanation:
-14=1/4 X
Solve for x!
Multiply both sides by the inverse of 1/4, which is 4! (1/4*4=1)
-14=1/4x
*4 *4
-56 = 1x
ALSO! Check your work!
-14= 1/4(-56) ??????
-14 = -14 YES
Your answer is A: -56
-14=1/4 X
Multiply both sides with the inverse of one over four (1/4*4=1)
-14=1/4x
*4 *4
-56 = 1x
Find the value of x.
Area of rectangle = 36
▅ х
x + 5
The value of x is 4, which is determined by the quadratic equation.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The rectangle of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that area of the rectangle = 36
Area of rectangle = width of the rectangle × length of the rectangle
Here the width of the rectangle = x
And length of the rectangle = x + 5
The rectangle of a rectangle = x × (x + 5)
36 = x² + 5x
x² + 5x - 36 = 0
x² + 9x - 4x - 36 = 0
(x + 9)(x - 4) = 0
x = -9 and x = 4
Take the value of x = 4 and the negative value is neglected because the dimension can't be negative.
Therefore, the value of x is 4.

Which of the following statements BEST proves that ∠XWY ≌ ∠ZYW?
A.
If two parallel lines are cut by a transversal, then corresponding angles are congruent.
B.
If two parallel lines are cut by a transversal, then complementary angles are congruent.
C.
If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
D.
If two parallel lines are cut by a transversal, then alternate exterior angles are congruent.
Answer: C
Step-by-step explanation:
The pair of angles created on the inner side of the parallel lines intersected by a transversal but on opposing sides of the transversal is known as an alternative interior angle. The correct option is C.
What are Alternate Interior angles?When two parallel lines are intersected by a transversal, the pair of angles created on the inner side of the parallel lines but on opposing sides of the transversal is known as an alternative interior angle. These angles are always equal in measure.
The best statements BEST that proves ∠XWY ≌ ∠ZYW is that If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
Hence, the correct option is C.

if x+y=2, calculate:
P=4x (x-3)+4y(y-3)+8xy
Answer:
Step-by-step explanation:
P = 4x(x - 3) + 4y(y - 3) + 8xy
= 4x² - 12x + 4y² - 12y + 8xy
= (4x² + 8xy + 4y²) - (12x + 12y)
= 4(x² + 2xy + y²) - 12(x + y)
= 4(x + y)² - 12(x + y)
x+y =2 ⇒ P = 4.2² - 12.2 = 16 - 24 = -8
What is the value of d that makes lines e and f parallel?
D=
10
13
85
115
Answer:
d = 13
Step-by-step explanation:
For the lines to be parallel, then
5(2d - 3) and (6d + 11 + 2d) will be corresponding angles and congruent, thus
5(2d - 3) = 6d + 11 + 2d ← distribute left side
10d - 15 = 8d + 11 ( subtract 8d from both sides )
2d - 15 = 11 ( add 15 to both sides )
2d = 26 ( divide both sides by 2 )
d = 13
The value of d that makes lines e and f parallel is 13units.
It is required to find the value of d.
What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
For the lines to be parallel, then
5(2d - 3) and (6d + 11 + 2d) will be corresponding angles and congruent.
According to given question we have,
5(2d - 3) = 6d + 11 + 2d
Distribute left side we get,
10d - 15 = 8d + 11
subtract 8d from both sides we get,
2d - 15 = 11
Add 15 to both sides we get,
2d = 26
Divide both sides by 2 we get,
d = 13units.
Therefore, the value of d that makes lines e and f parallel is 13units.
