Answer:
4 is the correct answer.
Number "4" can each term of the equation be multiplied by to eliminate the fractions before solving.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
To eliminate the fractions in the equation -3/4m -1/2m=2+1/4m, we need to find the least common multiple (LCM) of the denominators of the fractions, which is 4.
We can then multiply each term of the equation by 4 to eliminate the fractions.
So, multiplying both sides of the equation by 4, we get:
-3m - 2m = 8 + m
To simplifying, we have:
-5m = 8 + m
To solve for m, we can isolate the variable on one side of the equation. Adding 5m to both sides, we get:
4m = 8
Finally, dividing both sides by 4, we get:
m = 2

When ringing up a customer, a cashier needs 6 seconds to process payment as well as 1
second to scan each item being purchased. If it takes 20 seconds to ring up a customer,
how many items are being purchased?
Answer:
14 items
Step-by-step explanation:
20 seconds minus the six it takes to process purchase is 14 and if i takes 1 second to scan each item 14 times 1 is 14
Answer:
14
Step-by-step explanation:
to process payment = 6 sec
each item = 1 sec
total = 20 sec
From this information, we can formulate an equation where x = number of items being purchased.

I need help/ explanation. Algebra 2 15 points
Stretch the graph of f(x) vertically by a
factor of 2.
I need to know how to do this.
Answer:
For each point on the curve given, make a new point that has the same x value but double the y value.
Step-by-step explanation:
Pick several points on the graph given. the easiest points to pick would be (-2, 0), (0, 2) and (2, 0). That's the point on the far left, the point on the top of the curve in the middle, and the point on the far right. For each of these points, make a new point that's twice as high but has the same position left/right. For the far left point and the far right point, the new point will be the same as the old point because the height is zero and double zero is still zero. For the point in the middle the new height will be four since the old height was just two. Then draw a nice curve through those points and you will have the answer. It will be a mound that's twice as tall as the current mound but the same width.

Answer:
p = (2k + 1)i + j
q = 25i + (k + 4)j
p . q = 11
Find the dot product of p and q
(2k + 1)(25) + (k + 4) = 11
50k + 25 + k + 4 = 11
51k = -18
k = - 18/51 = –6/17.✅
b) p.q = |p||q|cos∅
p= (2k + 1)i + j = [2(-6/17) + 1)i + j ]= 5/17i + j
|p| = √ (5/17)² + 1²
|p| = √314/ 17 ( The square root doesn't cover the 17) = 1.0424
q = 25i + (k + 4)j = 25i + ( -6/17 + 4)j
q = 25i + 62/17 j
|q| = √ 25² + (62/17)²
= 25.2646
Now applying them to the formula above
We already have p.q = 11 from the question.
11 = (1.0424)(25.2646)Cos∅
11 = 26.3358Cos∅
Cos∅ = 11/26.3358
Cos∅ = 0.4177
∅ = 65.31°.
This should be it.

The acceleration will be 2.1 meters per second. The correct option is A.
What is acceleration?Acceleration of any object is defined as the variation in the speed of the object with the variation of the time. Acceleration is a vector term and to define it we require both the magnitude and the direction. The unit of the acceleration can be m / sec², miles / sec², etc.
Given that a car accelerates along a straight road, which is 15km long. The car reaches a speed of 75 km/h in 10s.
The acceleration will be calculated as below:-
Acceleration = Velocity / Time
Velocity = 75 km / h = 75 x ( 5 / 18 ) = 20.83 m / s
Acceleration = Velocity / Time
Acceleration = 20.83 / 10 = 2.08 or 2.1 m / s²
Therefore, the acceleration will be 2.1 meters per second. The correct option is A.

pasti salahCarson buys eggs and lemons at the store.
He pays a total of $39.62.
He pays $6.74 for the eggs.
He buys 8 bags of lemons that each cost the same amount.
Which equation could be used to determine xx, how much each bag of lemons costs?
Answer:
8x = 39.62 - 6.74
Step-by-step explanation:
Cost of 1 bag of lemons = $ x
Cost of 8 bags of lemons = 8 *x = 8x
Cost of 8 bags of lemons = Total cost - cost of the eggs
8x = 39.62 - 6.74
Answer:
3.
Step-by-step explanation:
[tex]x + y = 39.62 \\ x = 6.74 \\ y = \frac{39.62 - 6.74}{8} [/tex]
Mila needs to order some new supplies for the restaurant where she works . The restaurant needs at least 754 spoons. There are currently 313 spoons. If each set on sale contains 6 spoons, write and solve an inequality which can be used to determine x, the number of sets of spoons mila could buy for the restaurant to have enough spoons
Answer:x>73.5
-
Inequality: 6x + 313> 754
-
Step-by-step explanation:
The number of sets of spoons Mila could buy for the restaurant to have enough spoons:
x ≥ 74
What are inequalities?Inequalities are the comparison of mathematical expressions, whether one quantity is greater or smaller in comparison to another quantity.
We use these symbols to represent inequalities, '>' , '<', '≥', '≤'
Let x be the number of sets of spoons Mila buys. Each set contains 6 spoons, so the total number of spoons Mila will buy is 6x.
The restaurant needs at least 754 spoons, and there are currently 313 spoons, so the total number of spoons needed is:
754 - 313 = 441
we can write the inequality:
6x ≥ 441
To solve for x, we can divide both sides of the inequality by 6:
x ≥ 73.5
x ≥ 74
Therefore, Mila needs to buy at least 74 sets of spoons to ensure that the restaurant has enough spoons.
