Madelyn has a total of 15 dimes and quartets in her piggy bank. The total amount of money in her piggie bank is $2.85. Write and solve a system of equations to determine the number of dimes and the number of quarters in madelyn’s piggie bank.
The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Madelyn has a total of 15 dimes and quartets in her piggy bank. The total amount of money in her piggy bank is $2.85.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equations are given as,
0.10x + 0.25y = 2.85 ....1
x + y = 15 ....2
From equations 1 and 2, then we have
0.10(15 - y) + 0.25y = 2.85
1.5 - 0.10y + 0.25y = 2.85
0.15y = 1.35
y = 9
Then the value of the variable 'x' is given as,
x + 9 = 15
x = 6
The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.

3x+-6+2 > = 5x -8......can someone please solve this
Answer:
x ≤ 2
Step-by-step explanation:
If you referencing ">=" as greater than or equal to, follow the solution below:
Solve:
3x - 6 + 2 ≥ 5x - 8
Combine like terms.
3x - 4 ≥ 5x - 8
Subtract 5x from both sides.
-2x - 4 ≥ -8
Add 4 to both sides.
-2x ≥ -4
Divide both sides by -2, while flipping the inequality as well since you're dividing by a negative number.
x ≤ 2
Your answer would be x ≤ 2

Answer:
a. Line A and line C
b. Line B
c. Line A and line C
Step-by-step explanation:
a. Negative slopes slant downwards from your left to the right. Thus, line A and line C are negative slopes.
b. The line with the steepest slope is the line that appears to slant the more, whether downwards to the right or upwards to the right.
Line B appears to slant the more. Therefore line B has the steepest slope
c. The slope value of line A, that is rise/run = 4.
The slope value of line C = 4 also.
Parallel lines have the same slope value. Therefore, line A and C are parallel.

6. 98
Step-by-step explanation:
Number 1:
Remember: Diagonals are congruent (in this case scenario).
Remember: Consecutive angles are supplementary.
☆You are going to subtract 60 from 18p. (You are subtracting it from 180 specifically because the angles are on a straight angle, and a straight angle equals 180 degrees.)
[tex]180 - 60 = 120[/tex]
^Hence your answer^
Number 2:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 154 from 180.
[tex]180 - 154 = 26[/tex]
Number 3:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 35 from 180.
[tex]180 - 35 = 145[/tex]
Number 4:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 85 from 180.
[tex]180 - 85 = 95[/tex]
Number 5:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 51 from 180.
[tex]180 - 51 = 129[/tex]
Number 6:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 82 from 180.
[tex]180 - 82 = 98[/tex]

Find the degree of the polynomial.
Answer:
Degree of the polynomial = 3
Step-by-step explanation:
The given polynomial is [tex]18x^3y^2[/tex]
There are two variables in this polynomial i.e. x and y.
The exponent of x is 3 and that of y is 2.
We need to find the degree of the polynomial.
The degree of the polynomial is defined as the highest degree of any of the term.
In this case, the degree of polynomial is 3 as it has highest power than the power of y.

20 balloons have to be devided between a group A and Group B in the ratio 2:3. How many balloons will each group receive?
Answer:
There are 8 and 12 balloons for groups A and B, respectively.
Step-by-step explanation:
The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:
Group A
[tex]n_{A} = \frac{2}{2+3}\cdot (20)[/tex]
[tex]n_{A} = 8[/tex]
Group B
[tex]n_{B} = \frac{3}{2+3}\cdot (20)[/tex]
[tex]n_{B} = 12[/tex]
There are 8 and 12 balloons for groups A and B, respectively.

Robert needs to know if the triangle shown is a right triangle. Which equation could he use to help? A. 36+ 25= 49B. 25 + 36 = 49 C. 25 2 + 36 2 = 49 2 D. 36 2 –25 2 = 49 2
Answer:
C. 25² + 36² = 49²
Step-by-step explanation:
We use the Pythagoras theorem to determine if the triangle is a right angle triangle. The theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In geometry, hypotenuse is the longest side in a right angle triangle. This means it would have the highest number.
A. 36+ 25= 49
This is wrong because the theorem deal with the sum of the squares of the other two sides.
B. 25 + 36 = 49
This is wrong because the theorem deal with the sum of the squares of the other two sides.
C. 25² + 36² = 49²
This is correct as it matches the theorem.
D. 36² –25² = 49²
This is wrong because the theorem deal with the sum of the squares of the other two sides and not their difference.
