A cheeseburger contains 290 calories and a small fries contains 230 calories.
Explanation:Let X be the number of calories in a cheeseburger, and Y be the number of calories in a small fries.
From the given information, we can create two equations:
4X + 5Y = 23103X + 2Y = 1330To solve this system of equations, we can use substitution or elimination. Let's use elimination:
Multiply equation 1 by 3 and equation 2 by 4 to eliminate the X term:12X + 15Y = 693012X + 8Y = 5320Subtract the second equation from the first equation:12X + 15Y - 12X - 8Y = 6930 - 53207Y = 1610Divide both sides by 7:Y = 230Substitute the value of Y into either equation and solve for X:3X + 2(230) = 13303X + 460 = 13303X = 870X = 290Therefore, a cheeseburger contains 290 calories and a small fries contains 230 calories.

No plane contains these points, as we can see on the image, point J does not belong to any of the shown planes.
How many planes contain points J, K, and N?A plane contains a point if the point lies on the plane. For example, here you can see that plane X contains the points K and N.
But, if you look at the image, no plane contains the point J, then there is no plane that contains the 3 points J, K, and N, so the correct option is 0.

Write the word sentence as an equation. Then solve. A number x multiplied by 2/5 is 3/20 .
The given word sentence translates into the algebraic equation 2/5 * x = 3/20. Solving this equation returns x = 3/8 as the solution.
Explanation:The word sentence 'A number x multiplied by 2/5 is 3/20' is translated into an algebraic equation as: 2/5 * x = 3/20. To solve for x, you could do cross multiplication or simply divide both sides of the equation by 2/5, which gives: x = (3/20) / (2/5). Simplifying this equation leads to: x = 3/20 * 5/2 = 15/40 = 3/8. Therefore, the solution to the equation is x = 3/8.

If CDEF ≅ MNPQ, then EF≅ _____
.
PQ.
QM.
MN.
NQ
Final answer:
In the context of congruent polygons, side EF of polygon CDEF is congruent to side PQ of polygon MNPQ due to the corresponding order of sides in congruent figures.
Explanation:
The question refers to congruent figures in geometry, specifically congruent polygons. If polygons are congruent, all corresponding sides and angles are congruent as well. Therefore, if CDEF ≅ MNPQ, then side EF must be congruent to the side of polygon MNPQ that corresponds to EF in the order of letters given. Following the order, side EF corresponds to side PQ.

the expression 12x+15x-11x can be combined because of which property
A. commutative property of addition
B. distributive property
C. additive inverse property
D. multiplicative property
The expression 12x+15x-11x can be combined using the associative property of addition.
Explanation:The expression 12x+15x-11x can be combined by using the associative property of addition.
First, combine the like terms which have the same variable, in this case 'x'. Add the coefficients of the like terms, which are 12, 15, and -11. 12x + 15x - 11x = (12 + 15 - 11)x = 16x.Therefore, the simplified expression is 16x. The associative property of addition allows us to group the terms in any order and still get the same result.
Final answer:
The expression 12x + 15x - 11x can be simplified due to the associative property of addition, enabling terms to be grouped and combined to yield a simplified form of 16x. The correct option is not provided in the choices, but would be the associative property, not listed in the student's options.
Explanation:
The expression 12x + 15x - 11x can be simplified by combining like terms, which is possible because of the associative property of addition. This property allows us to group numbers in an addition expression in any way we choose without changing the result.
Therefore, using the associative property, we can group and combine the terms with 'x' to get (12x + 15x) - 11x, which simplifies to 27x - 11x, and then further to 16x.
The correct answer to the question is Option A: associative property of addition, though it is important to note that this option was not listed in the initial question provided. The commutative property allows us to change the order of the terms without changing the result, but does not directly apply to the combination of like terms.
Nevertheless, both the associative and commutative properties are used when combining like terms in algebra.
Luigi is an urban planner. as an independent contractor, he charges $140 fee plus $ 25 per hour for each contract with the city.
Write a function to represent this scenario where Y represents the total amount her changes for a project and x represents the number of hours worked on a project
x = hours 25 per hour = 25x
y = total
so y = 25x +140
Answer: y = 140+25x
Step-by-step explanation:
Since According to the question, Luigi initally charged $140.
And, per hour he charged an additional amount $25 for each contract with the city.
Here, x represents the number of hours worked on a project.
Thus the additional amount after x hours = 25x
So, the total amount he charged in x hours= 140+ 25x
And, according to the question y represents the above change.
Thus, we get a function for the given situtaion
which is , y= 140+ 25x , where x is number of hours and y is total amount charged.

anonymous 4 years ago A technical writer makes $45,000 per year and has just begun contributing 8% of her salary to her 401(k) plan. If her employer matches 6% of her contributions, how much will have been contributed to the 401(k) plan after 2 years?
Answer:
$7,632 would have been contributed to the 401(k) plan after 2 years.
Step-by-step explanation:
A technical writer makes salary per year = $45,000
She contributing 8% of her salary to her 401(k) plan = 8% of 45,000
0.08 × 45,000 = $3,600
Her employer matches 6% of her contributions = 6% of 3,600
= 0.06 × 3,600 = $216.00
Total contribution for one year = 3,600 + 216.00 = $3,816
After 2 years = 3,816 × 2 = $7,632.00
$7,632 would have been contributed to the 401(k) plan after 2 years.
