Answer: 21
Step-by-step explanation: We can use the method: Keep, Change, Flip.
1. Keep 7.
If you want 7 to become a fraction, you can do it like this: \(\frac{7}{1}\)2. Change division to multiplication.
It's very simple. Just change the sign.3. Flip \(\frac{1}{3}\).
It's like converting it into a improper fraction. \(\frac{1}{3}\) is now \(\frac{3}{1}\).Now we can solve!
\(\frac{7\times3}{1\times1} =21/1\)
Therefore, your answer is 21/1 or just 21.

10.Is 3/4 equivalent to 45/70?
When comparing fractions, you can multiply or divide to find equivalent fractions.
Number 1: If I were to multiply 5 to 45, I would have to do the same to the numerator of the fraction. 45/5 = 9. So we know now that 5 times 9 equals 45. Lets do that to the numerator also. 4 times 9 equals 36 so 4/5 times nine is 32/45.
So yes, this would be equivalent.
Number 2: 7/8 times 4 equals 28/32
Yes, this would be equivalent.
Number 3: 10 times 10 is 100, 1 times ten is NOT 30.
No, this would not be equivalent.
Number 4: 8 times 4 equals 32, 6 times 4 equals 24.
Yes, this would be equivalent.
Number 5: 30/5 equals 6. 70/8 is NOT 6.
No, this would not be equivalent.
Number 6: 24/2 equals 12. 100/3 is not 12.
No, this would not be equivalent.
Number 7: 30/2 is 15. 60/10 is NOT 15.
No, this would not be equivalent.
Number 8: 20/1 equals 20. 100/5 is also 20.
Yes, this would be equivalent.
Number 9: 20/5 equals 4. 30/6 is not 4.
No, this would not be equivalent.
Number 10: 45/3 is 15, 70/4 is NOT 15.
No, this would not be equivalent.

Step-by-step explanation:
what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

A set of numbers represents the range of this function as whole numbers greater than 0.
What is the range or domain of a function?The domain of a function is the set of values that we are allowed to enter into our function. This set consists of the x values for a function like f. (x). The set of values that a function may accept as input is known as its range. The function outputs this list of values once we enter an x value.
The collection of all potential output values that a function might produce is known as its range.
In this instance, the function displays the positive whole integer representing the number of persons entering the performance hall each minute.
The set of whole integers bigger than 0 is hence the range of the function.
The appropriate response is thus A. Whole numbers larger than 0.

3) Find the discounted price, to the nearest cent, for a portable CD player that sells for $59.95 and is on sale for 30% off.
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:
42 dollars
Step-by-step explanation:
$59.95-30% is 41.965. We round this to 42 dollars.
If it sells for 59.95, and it's on sale for 30% off, you can use this equation to find the new, discounted price:
59.95 x 0.70 (the 0.70 resembling 100-30%)
The answer of this equation is 41.965, rounded to 41.97.
Percent of change: about 30% (29.9917% decrease)

What number would you subtract from both sides of the equation to solve for c?
c + 7 = -14
(Only write the number that you would subtract. Do no write the equation.)
To solve for c in the equation c + 7 = -14, you would subtract 7 from both sides of the equation.
A sector of a circle of radius 8cm has an area of 120° at the centre. Find its perimeter
Answer:
Area of the sector = \(24\pi ^{2}\)
The perimeter of the sector of the given circle is 32.75 cm.
The perimeter of a sector is given by the sum of the arc length and the two radii that form the sector. To find the perimeter of this sector, we need to find the length of the arc and the two radii.
The area of the sector is given as 120° at the center. We can use this information to find the length of the arc by using the formula for the area of a sector:
Area of sector = (angle/360) x πr²
where r is the radius of the circle and angle is the central angle of the sector in degrees.
In this case, we have:
120/360 x π x 8² = 33.51 cm² (rounded to two decimal places)
The length of the arc can be found by using the formula:
Arc length = (angle/360) x 2πr
In this case, we have:
(120/360) x 2π x 8 = 16.75 cm (rounded to two decimal places)
The two radii that form the sector have lengths of 8 cm each.
Therefore, the perimeter of the sector is the sum of the arc length and the two radii:
Perimeter = arc length + 2r
= 16.75 + 2(8)
= 32.75 cm (rounded to two decimal places)
Therefore, the perimeter of the sector is approximately 32.75 cm.

b. x(16+36)
C. 4(4x + 9)
d. 2(8x + 18)
e. 2(8x + 36)
Answer:
2(8x + 18) and 4(4x + 9)
Step-by-step explanation:
16 and 36 are both evenly divisible by 2 and 4. Thus, possible equivalents of 16x + 36 are 2(8x + 18) and 4(4x + 9).
Expressions equivalent to 16x + 36 are 4(4x+9) and 2(8x + 18).
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.
Given expression
16x + 36
= 4.4x + 4.9
16x + 36 = 4(4x+9)
= 2.2(4x + 9)
16x + 36 = 2(8x + 18)
Hence, 4(4x+9) and 2(8x + 18) are equivalent to 16x + 36.

Determine whether the statement is always, sometimes, or never true.
The acute interior angles of a right triangle are complementary.
always
sometimes
never
Answer:
The acute interior angles of a right triangle are complementary.
Step-by-step explanation:
that if an acute angle and the obtuse angle is added, its sum is 180 degrees. ⟹ (5θ + 4°) + (θ – 2°) + (3θ + 7°) = 180°. A supplementary angle can be composed of one a cute angle and another obtuse angle. Thanks 0. y = 180 -x. range of x = [1º 89º] then range of y is [91º 179º] so this proves that always the supplementary to acute angle is always obtuse.
I hope this helped have a good rest of your day
Answer:
Always
Step-by-step explanation:
Let's name the acute angles x and y,
We are given that it's a right triangle so one angle is 90 degrees.
Sums of angles in a triangle add up to 180 degrees.
So,
x+y+90=180
x+y=90
The acute angles add up to 90 degrees so they are complementary.
