Using the numbers 1,2,3,4 only once and the operations + or x as many times as you like, write an expression that evaluates to 16. Use this expression and any combination of those symbols as many times as you like to write an expression that evaluates to 816.
Final answer:
To obtain 16 using the numbers 1, 2, 3, and 4 with addition and multiplication, the expression is 4 x (3 + 1). To reach 816, place 8 in the hundreds place by calculating 8 x 100 and add the previously obtained 16.
Explanation:
To create an expression that evaluates to 16 using the numbers 1, 2, 3, 4 each only once and the operations + or x as many times as you like, we can use the following expression:
4 x (3 + 1) = 16
To write an expression that evaluates to 816 using our 16, simply prepend the number 8 to 16, which can be done by using multiplication and addition as follows:
8 x 100 + 4 x (3 + 1) = 800 + 16 = 816
This utilizes the concept that numbers can be broken down into sums of multiples of powers of 10 (place value), which is a fundamental principle in mathematics.

A local hamburger shop sold a combined total of 605 hamburgers and cheeseburgers on Friday. There were 55 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Friday?
The local hamburger shop sold 275 hamburgers on Friday, which was determined by setting up a system of equations to find the individual sales of hamburgers and cheeseburgers based on the given total sales and difference in numbers.
The question asks us to determine how many hamburgers were sold on a specific day, given the total number of hamburgers and cheeseburgers and the difference in their individual sales numbers. Let's denote the number of hamburgers sold as H and the number of cheeseburgers as C. We are told that the total number of burgers sold is 605, so we can write the equation H + C = 605. We also know there were 55 more cheeseburgers sold than hamburgers, giving us the equation C = H + 55. To find the number of hamburgers sold, we need to solve these two equations simultaneously.
Substituting the second equation into the first, we get:
H + (H + 55) = 6052H + 55 = 6052H = 605 - 552H = 550H = 550 / 2H = 275Therefore, the hamburger shop sold 275 hamburgers on Friday.

what are two`fractions whose product is -3/5
To find two fractions whose product is -3/5, we can choose any two fractions that follow the rules of multiplying fractions. For example, the fractions 1/5 and -3/1 or -4/5 and 3/4 both have a product of -3/5.
Explanation:To find two fractions whose product is -3/5, we need to consider the rules of multiplying fractions. When we multiply two fractions, we multiply their numerators to get the new numerator and multiply their denominators to get the new denominator. In this case, we can choose any two fractions that satisfy these rules and have a product of -3/5.
For example, let's consider the fractions 1/5 and -3/1. When we multiply these fractions, we get (1 × -3) / (5 × 1) = -3/5.
Another example is the fractions -4/5 and 3/4. When we multiply these fractions, we get (-4 × 3) / (5 × 4) = -12/20, which can be simplified to -3/5.

Sasha lives 1,493 miles from her grandmother. One year, Sasha's family made 4 round trips to visit her grandmother. How many miles did they travel in all?
Final answer:
Sasha's family traveled a total of 11,944 miles over the course of the year by making 4 round trips to visit her grandmother, with each round trip being 2,986 miles.
Explanation:
The student is asking a mathematics question related to calculating the total distance traveled during multiple round trips. In this problem, Sasha's family traveled 1,493 miles to visit her grandmother, and they made this trip 4 times in a year. To find out how many miles they traveled in all, we need to calculate the distance of one round trip and then multiply by the number of round trips made.
A round trip consists of going to the grandmother's house and then returning back, so that's 1,493 miles each way. Therefore, one round trip would be:
1,493 miles (to grandmother) + 1,493 miles (back) = 2,986 miles.
Since they made 4 round trips, we calculate:
2,986 miles (for one round trip) x 4 (round trips) = 11,944 miles.
Thus, Sasha's family traveled a total of 11,944 miles to visit her grandmother over the course of the year.

Francisco makes $12 per hour doing part time work on Saturdays. He spends $4 on transportation to and from work. The equation y=12x-4 gives his earnings y, after transportation costs, for working x hours. Make a table for values for this situation. Please help.
In the given linear equations, we can use the equation y=12x-4 to create a table of earnings for different numbers of hours Francisco might work, taking into account his transportation costs. For example, if he does not work he loses $4 (-$4); if he works one hour he earns $8; if he works two hours he earns $20; if he works three hours he earns $32.
Explanation:In the equation y=12x-4, 'x' represents the number of hours Francisco works, and 'y' gives his earnings after transportation costs. Let's start creating a table using different values for 'x (hours)'.
For 0 hours (x=0), we substitute x into the equation to get y = 12*0 - 4 = -$4. Since Francisco can't earn negative money, we can consider this as him simply not going to work.For 1 hour (x=1), y = 12*1 - 4 = $8.For 2 hours (x=2), y = 12*2 - 4 = $20.For 3 hours (x=3), y = 12*3 - 4 = $32.So, the table would look something like this:
(0, -$4)(1, $8)(2, $20)(3, $32)This table provides four possible combinations of hours worked (x) and the corresponding earnings (y), taking into account the cost of transportation.

What is the distance between point A (−1, 3) and point B (−7, 3) ?
1 units
3 units
6 units
8 units
Answer:
The distance between point A and the point B is:
6 Units.
Step-by-step explanation:
The Cartesian plane is known as 2 perpendicular number lines between them, one horizontal and one vertical, which are cut at a point called the origin.
And the coordinates are given by the values of X and Y (x, y)
Where X are horizontal values and Y are vertical values.
By placing the point (−1, 3) and the point (−7, 3) we realize that two values of Y are exactly the same on the line.
But the values of X are different from each other, so the units of the distance between them are counted.
-7U - (- 1U) = -6U
But since the distance units cannot be negative then the answer is 6 units of distance.
