Answer: 3+4=7
Step-by-step explanation:
So basically let’s say
A= #1
And So right now we have A+B=7
B= #2
So b=a-1 right? Yeah ok so then what you need to do is find A....
So 7-1=6 and 6÷2 = 3 so
A=3
And Than 3+4=7 so that is your answer
B=4
The two-digit number which meets the criteria that its digits sum to 7 and the tens digit is one more than twice the units digit, is 52.
Explanation:Let's denote the units digit as 'x' and the tens digit as 'y'. We know that the sum of the digits is 7, which gives us the equation x + y = 7. Secondly, we know the tens digit is one more than twice the units digits, so y = 2x + 1. We can solve these two equations simultaneously.
Substituting y from the second equation in the first gives us x + (2x + 1) = 7. Simplifying this results in 3x + 1 = 7. Upon solving we find x = 2. Substituting x = 2 into the first equation we get y = 7 - 2 = 5. Thus, the number is 52.

Which of the following equations represents a line that is parallel to the line represented by 3x + 5y = –3? A. 3x + 5y = 2 B. 6x + 10y = –6 C. –5x + 3y = 2 D. –3x + 5y = –3
The equation that represents a line parallel to 3x + 5y = –3 is A. 3x + 5y = 2, as it only differs in the y-intercept from the original line, therefore having the same slope which ensures it's parallel.
Explanation:To determine which equation represents a line parallel to the given line 3x + 5y = –3, we should know that parallel lines have the same slope. The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Let's first rewrite the given equation in slope-intercept form.
3x + 5y = –3
5y = -3x - 3
y = -3/5x - 3/5
The slope of this line is -3/5. We now look for an equation among the options which has the same slope of -3/5.
A. 3x + 5y = 2 is the correct choice as it only differs in the y-intercept, which makes it parallel to the original.
B. 6x + 10y = –6 is actually equivalent to the original equation when divided by 2, hence it's the same line, not merely parallel.
C. –5x + 3y = 2 has a different slope.
D. –3x + 5y = –3 has a different slope.

Answer:8 ft.
Step-by-step explanation:
Given: right Δ
it's 8 because you know the triangle is a right triangle which means that you can use the Pythagorean Theorem. which would be
x²= 10²- 6²
x²= 100-36
x²=64
x=8
or you can use the Egyptian triangle which is a right triangle that's sides are equal to 3,4,5. This triangle is just double the Egyptian triangle which means everything is times 2. So knowing that and that two sides of this triangle is double two sides of the other triangle, you'll find that the third side is 8, because:
6÷3=2
10÷5=2
so now proving its double you can multiply by four by two since the answer of the previous problems is two

A driver swims 5.875 feet up to the surface of the water.Which number represents the driver position in relation to the surface before swimming to the top. A.-5.9 B. -5 3/4 C.-58 D.-5 7/8 feet
Answer:
-5 7/8 ft (Answer D)
Step-by-step explanation:
Note that 5.875 ft is the same as 5 7/8 ft.
The diver is initially 5 7/8 ft beneath the water surface, so we give that 5 7/8 ft the negative sign:
-5 7/8 ft represents the diver's position in relation to the surface.
The driver's position in relation to the surface before swimming to the top is represented by D. -5 7/8 feet. This is because in this scenario, a negative number signifies underwater depth.
Explanation:In mathematics, the term 'relation' is often used in the context of functions and refers to the way two sets of numbers are interconnected. In your scenario, a negative number is used to signify the driver's position underwater, while a positive number indicates their position above water. Therefore, if the diver swims 5.875 feet up to the surface, this would mean their original position was -5.875 feet. When expressed in decimal form, this would be -5.9, and when expressed in fractions, it would be -5 7/8 feet. Hence, the correct answer would be D. -5 7/8 feet.

Which statements about the system are true? Select two options. y = y equals StartFraction 1 over 3 EndFraction x minus 4.x – 4 3y – x = –7 The system has one solution. The system consists of parallel lines. Both lines have the same slope. Both lines have the same y–intercept. The equations represent the same line.
Answer:
The system consists of parallel lines ⇒ 2nd answer
Both lines have the same slope ⇒ 3rd answer
Step-by-step explanation:
Lets revise the types of the solutions of the system of equations
Case 1:
→ If the two equations have the same coefficients of the two variables
and different numerical terms then the two equations represented
by two parallel lines
Ex: ax + by = c , ax + by = d
Case 2:
→ If the two equations have the same coefficients of the two variables
and same numerical term then the two equations represented
by the same line
Ex: ax + by = c , ax + by = c
Case 3:
→ If the two equations have different coefficients of one of the variables
or the two variables then they represented by two intersected lines
and the system has one solution
Ex: ax + by = c , dx + ey = f
The system of equation is
* y = [tex]\frac{1}{3}[/tex] x - 4
* 3 y - x = -7
Multiply the first equation by 3
∴ 3 y = x - 12
Subtract both sides by x
∴ 3 y - x = - 12 ⇒ (1)
∵ 3 y - x = - 7 ⇒ (2)
The system of equations has same x-coefficient and same y-coefficient
in both equations but the numerical terms are different, then they
represented by two parallel lines as first case above
and parallel lines have the same slope
The system consists of parallel lines
Both lines have the same slope

Two rectangles are similar. The length and width of the first rectangle are 12
and 5, respectively. The length and width of the second rectangle are 14.4 and
6, respectively. The scale factor used to get from the first rectangle to the
second one is
Answer:
scale factor = 1.2
Step-by-step explanation:
To determine the scale factor, calculate the ratio of the length of the second rectangle to the length of the first rectangle. The corresponding ratio of widths should also equal the same ratio.
scale factor = [tex]\frac{14.4}{12}[/tex] = [tex]\frac{6}{5}[/tex] = 1.2
Final answer:
The scale factor used to get from the first rectangle to the second one is 1.2.
Explanation:
The scale factor used to get from the first rectangle to the second one can be found by comparing the dimensions of the two rectangles. The length of the first rectangle is 12 and the length of the second rectangle is 14.4. Dividing the length of the second rectangle by the length of the first rectangle gives us:
Scale factor = length of second rectangle / length of first rectangle = 14.4 / 12 = 1.2
So, the scale factor used to get from the first rectangle to the second one is 1.2.

You have a 10-ml vial of aminophylline labeled 25 mg per ml. How many ml must be injected to administer a dose of 125mg
Answer:
5
Step-by-step explanation:
You do 125/25 to find the number of ml of aminophylline. Answer: 5
To administer a dose of 125 mg of aminophylline, one must inject 5 ml.
The student is asking how many milliliters (ml) must be injected to administer a dose of 125 mg of aminophylline when the vial is labeled 25 mg per ml. To calculate this, we use the formula:
Dose (mg) = Volume (ml) times Concentration (mg/ml)
Since we need to administer 125 mg and we know the concentration is 25 mg/ml, we arrange the formula to solve for volume:
Volume (ml) = Dose (mg) / Concentration (mg/ml)
Volume (ml) = 125 mg / 25 mg/ml = 5 ml

The weight of the books carried in a backpack depends on the number of books in the backpack. Susan’s books weigh from 1 pound to 3.5 pounds each and she carried at most 4 books. Find a reasonable domain and range for the situation. (please, a little help here?)
Final answer:
The domain for Susan's backpack situation is {0, 1, 2, 3, 4}, representing the number of books she can carry, while the range is from 0 to 14 pounds, representing the total weight of the books she might carry.
Explanation:
To find a reasonable domain and range for Susan's backpack situation, we need to consider the lightest and heaviest books she might carry. Since Susan can carry at most 4 books and each book weighs between 1 pound to 3.5 pounds, we can define the possible weights of the books.
For the domain, we consider the number of books Susan could possibly carry. The domain would therefore be: {0, 1, 2, 3, 4}. She could carry no books or up to 4 books.
For the range, we consider the total weight of the backpack based on carrying the lightest to the heaviest books. The minimum weight would be 0 pounds (if she carries no books) and the maximum weight would be 3.5 pounds imes 4 books = 14 pounds. So the range of weights would be from 0 to 14 pounds. However, we must remember that the weight can also be any reasonable value in between, for instance when carrying books of varying weights.
In conclusion, the domain for the number of books would be {0, 1, 2, 3, 4} and the range for the total weight of the books would be any value between 0 to 14 pounds, inclusive.
