y=-4
HEY PLEASE HELP. The student's savings box had accumulated 35 twenty and fifty cent coins in one month, in the total amount of 10.3 euros. Several 20 and several 50 cent coins are in the box.
Answer: 11 and 24
Step-by-step explanation:
Given
There are 35- 50 cents and 20 cents coins
The total of them is 10.3 euros
Suppose no of 50 cents coins is x and 20 cents is y
so we can write
[tex]\Rightarrow 0.5x+0.2y=10.3\quad \ldots(i)[/tex]
Also,
[tex]\Rightarrow x+y=35\quad \ldots(ii)[/tex]
Solving (i) and (ii) we get
[tex]x=11; y=24[/tex]
There are 11 fifty cent and 24 twenty cents coins

choose the best selection for the quadrilateral with vertices at following points
0,0 -2,3 7,0 5,3
Answer:
The quadrilateral has two pairs of opposite parallel sides and (from the graphing of the points) it is slanted from the vertical, therefore, it is a;
B. Parallelogram
Step-by-step explanation:
The coordinates of the vertices of the given quadrilateral are;
(0, 0), (-2, 3), (7, 0), (5, 3)
Arranging the coordinates according to their y-values and labelled gives;
A(-2, 3), B(5, 3), C(0, 0), D(7, 0)
The graph of the points created with Microsoft Word and Microsoft Excel is attached
From the graph, we have;
Segment AB is parallel to segment CD
The length of segment AB = √((5 - (-2))² + (3 - 3)²) = 7
The length of segment CD = √((7 - 0)² + (0 - 0)²) = 7
∴ The length of segment AB = The length of segment CD
The distance between segment AC and segment BD = Length of segment AB at point A = Length of segment CD at point C
∴ Segment AC is parallel to segment BD (The distance between two parallel lines is the same all through)
The quadrilateral is also observed to be slant from the vertical
Therefore the quadrilateral is a parallelogram

Pete found 5/6 of a party sand which in the refrigerator. He took 1/2 of the 5/6 of the sand which to his neighbors. How much of the original sand which did pete take to his neighbors.
Answer:
1/2
Step-by-step explanation:
Pete found 5/6 of a party sand which in the refrigerator. He took 1/2 of the 5/6 of the sand which to his neighbors.
This is calculated as:
1/2 × 5/6
= 5/12
Hence, he took 5/12 of the sand
How much of the original sand which did pete take to his neighbors.
Let the original sand be represented as 1
Hence:
5/6 = 5/12 sand
1 = x
Cross Multiply
5/6x = 1 × 5/12
x = 5/12 ÷ 5/6
x = 5/12 × 6/5
x = 1/2
Therefore, pete took 1/2 of the original sand to his neighbors.

If the cos A= 9/41 , what does the tan A equal?
Answer:
tanA = 40/9
Step-by-step explanation:
Try to construct a right-angled triangle with it's adjacent side=9 and hypotenuse = 41,
By pyth. theorem, we can get the remaining side (opposite side)
= √(41^2 - 9^2)
= 40
tanA = oppside side/ adjacent side
tanA = 40/9

A online video-streaming services charges a one-time membership fee of $20 and a monthly fee of $7.50. How many months of membership will $115 pay for
Answer:
Number of months= 12 months
Step-by-step explanation:
Giving the following information:
One time fee= $20
Monthly fee= $7.5
Total cost= $115
To calculate the number of months, we need to use the following formula:
Number of months= (total cost - one time fee) / monthly fee
Number of months= (115 - 20) / 7.5
Number of months= 12.67
Number of months= 12 months

Answer:
c. infinitely many solution
Answer: C
Step-by-step explanation:
5 + -2x = 4 + -2x + 4 + x
Reorder the terms:
5 + -2x = 4 + 4 + -2x + x
Combine like terms: 4 + 4 = 8
5 + -2x = 8 + -2x + x
Combine like terms: -2x + x = -1x
5 + -2x = 8 + -1x
Solving
5 + -2x = 8 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
5 + -2x + x = 8 + -1x + x
Combine like terms: -2x + x = -1x
5 + -1x = 8 + -1x + x
Combine like terms: -1x + x = 0
5 + -1x = 8 + 0
5 + -1x = 8
Add '-5' to each side of the equation.
5 + -5 + -1x = 8 + -5
Combine like terms: 5 + -5 = 0
0 + -1x = 8 + -5
-1x = 8 + -5
Combine like terms: 8 + -5 = 3
-1x = 3
Divide each side by '-1'.
x = -3
Simplifying
x = -3

The identity [tex]A^2 - B^2 = (A + B) (A - B)[/tex] is true for all values of A and B. Compute the whole number value of [tex]2021^2 -2022^2[/tex]
Answer:
[tex]2021^2 - 2022^2 = -4043[/tex]
Step-by-step explanation:
Given
[tex]A^2 - B^2 = (A + B) (A - B)[/tex]
Required

twice the difference of c and 19
Answer:
2(c - 19)
Step-by-step explanation:
Twice the difference of c and 19
2 (c - 9)
When it says "twice the difference.." it means you will times the difference of c - 19 by 2
Answer:
Difference of c and 19=c-19
Twice of (c-19)=2(C-19).
So, the final answer is 2(c-19).

If triangle BNV ~ triangle BRG, BR=4x+7 and BG= 18 find the value of x
Answer:
x=5
Step-by-step explanation:
The value of [x] would be 4.17.
What is triangle?A triangle is a polygon with three edges and three vertices.
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is triangle BNV is similar triangle BRG,
Since triangle BNV is similar triangle BRG, we can write -
4x + 7 = 18
4x = 25
x = 4.17
Therefore, the value of [x] would be 4.17.
