Janice currently has 26 marbles and is collecting 3 per week. Oliver currently has 10 marbles and is collecting 5 per week. how many weeks will it take so that janice and oliver have the same amount of marbles?
For, Janice and Oliver have the same number of marbles, it will take 8 weeks.
Define algebraic equation.A term in an algebraic expression that is referred to as a linear expression is either a constant or a variable raised to the first power. Or, to put it another way, none of the exponents can be higher than 1.
Positive or negative numbers can be used as coefficients in linear equations. It matters what the exponent is. When one variable in the equation is raised to a power greater than 1, the entire equation becomes nonlinear.
Given,
Oliver presently has 10 marbles and is collecting 5 per week, whereas Janice currently has 26 marbles and is adding 3 each week.
Let x be the number of weeks.
This implies,
Algebraic equation,
26 + 3x = 10 + 5x
26 - 10 = 5x - 3x
16 = 2x
x = 16/2
x = 8
So that Janice and Oliver have the same number of marbles, it will take 8 weeks.

Find the sum of all positive integers such that their expression in base 7 digits is the reverse of their expression in base 16 digits. Express your answer in base 10.
The sum of all positive integers such that their expression in base 7 digits is the reverse of their expression in base 16 digits is 58.
What is meant by positive integer?Natural numbers are numbers used in mathematics for counting (as in "there are six coins on the table") and ranking (as in "this is the third largest city in the country"). Cardinal numbers are used for counting, and ordinal numbers are used for ordering. Natural numbers, which have no mathematical features, are sometimes employed as labels.
When the number is a 1 digit number (1 digit number in base 7)- the numerals 0, 1, 2, 3, 4, 5, and 6
When the number is a 2 digit number=a×7+b=b×16+a / subtract (a+b) a×6=15×b / divide by 3 2a=5b indicating an is divisible by 5 meaning a=5 (since if a=0 then b=0 and the phrase ab is not defined because the digit that indicates the highest number in a given number cannot be 0) meaning b=2. So there is just one two-digit number=52 (in base 7)=37. (in base 10).
When the number is three digits, subtract (a+c+7b) 48a=255c+9b / divide by three 16a=85c+3b. c cannot be 0 because this indicates that the expression cba is not defined.
If c=1, 16a=85+3b
There are no answers to that problem. If c>1, this suggests that 16a=85c+3b>=170, implying that a>6. This, however, is not possible! As a result, there is no solution.
As a result, the sum of all positive integers is 58.

What is parallel line class 4?.
Coplanar, straight lines that just don't cross at any point are considered parallel lines in geometry. Parallel planes were also planes that never cross each other in the same three-dimensional space.
What are lines that are parallel and perpendicular?If two lines are in the same plane and never cross, they are said to be parallel. They are equidistant lines, which means that their separation is constant. The symbol || is used to depict parallel lines. For instance, the symbol AB || CD denotes the parallelism of the line segments AB and CD. On the other hand, two straight lines are said to be perpendicular if they cross at a 90° angle.
A description line is what?A line has length but no breadth, making it a one-dimensional object. A line is made up of several points that continue indefinitely in opposing directions.

Answer:
The amount of the ticket will be $531.
Step-by-step explanation:
If the driver is charged $30 for every mile above the speed limit, than :
diff = 52.7 - 35
= 17.7 miles

To pay for a home improvement project that totals $16,000, Genesis is choosing between taking out a simple interest bank loan at 8% for 3 years or paying with a credit card that compounds monthly at an annual rate of 15% for 7 years. Which plan would give Genesis the lowest monthly payment?
A. The monthly credit card payment would be $511.11, which is lower than the monthly payment on the bank loan.
B. The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment.
C. The monthly payment on a bank loan would be $551.11, which is lower than the monthly credit card payment.
D. The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.
The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.
What is simple interest?The simple interest earned can be calculated by using this formula
A = P(1 + rt)
A is the future value.
P is the principal value.
r is the interest rate.
t is the time.
Now Substituting the values into the formula, we have,
A = 16,000[1 + (0.08 × 3)]
A = 16,000[1 + 0.24]
A = 16,000× 1.24
Future value, A = $19,840.
Following that, we will compute the monthly payment over a 36-month period as follows:
Monthly payment = Future value/Time
Monthly payment = 19,840/36
Monthly payment = $551.11
Similarly, we will compute the credit card's compound interest:
A = 16000[1 + (0.15/12)]⁽¹² ˣ ⁷⁾
A = 16000[1 + 0.025]⁸⁴
A = 16000× 1.025⁸⁴
A = 9000 × 3.49258954
Future value, A = $45425.80
Following that, we will compute the monthly payment over an 84-month period as follows;
Monthly payment = Future value/Time
Monthly payment = 45425.80/84
Monthly payment = $540.78.
Thus, the monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.

Make sure you use topic sentences to make a claim and transition words to support the claim, creating clear focus and logical order to your reasoning..
The total dollar amount saved by Mo is y = $90 + $8h. The y-intercept is the amount of money he has already saved, $90. The slope is the rate at which the amount saved would increase, $8.
The total dollar amount saved by Merv is y = $50 + $8.50h. The y-intercept is the amount of money he has already saved, $50. The slope is the rate at which the amount saved would increase, $8.50.
Mo would reach the goal. Because the total amount of money he would have saved is $154.
Who would reach the goal?A linear equation is an equation that has a single variable that is raised to the power of one. When drawn on a graph, a linear equation is a straight line.
The general form of a linear equation is:
y = mx + b
Where:
m = slope b = y-interceptThe equation that would be used to represent the total amount of money saved is:
Equation that represents the amount that should be saved by Mo:
y = $90 + $8h
Substitute h with 8
y = $90 + $8(8)
y = $90 + $64 = $154
The total dollar amount saved by Merv is:
y = $50 + $8.50h
Substitute h with 8
