If -2a > 6, then a < -3. true or false
Answer:
True
Step-by-step explanation:
[tex]-2a>6[/tex]
Multiply both sides by -1 (Flip the signs and symbol):
[tex]\left(-2a\right)\left(-1\right)<6\left(-1\right)[/tex]
[tex]2a<-6[/tex]
Divide both sides by 2:
[tex]\frac{2a}{2}<\frac{-6}{2}[/tex]
[tex]a<-3[/tex]

Hey there!
ANSWER: [tex]\frac{23}{20}[/tex]
EXPLANATION:
To find the answer to your question, you will need to add.
[tex]\frac{3}{4}+\frac{2}{5}[/tex]
First, multiply the denominator.
[tex]5*4=20[/tex]
So the denominator will be 20.
Now move on to the numerator. Multiply 5 by 3.
[tex]5*3=15[/tex]
Now multiply 4 bu 2.
[tex]4*2=8[/tex]
If you want to get the numerator, add what you got after multiply.
[tex]15+8=23[/tex]
The numerator is 23. So now let's complete the fraction.
[tex]\frac{23}{20}[/tex]
This is your answer!

The scale from a map to actual distance is 2.5 cm to 620 mi. The distance on the map between Chicago and Boston is about 3.5 cm. What is the approximate distance, in miles, between Chicago and Boston? Show your work. Please help me
Answer: 868 miles
Step-by-step explanation:
Given: The scale from a map to actual distance is 2.5 cm to 620 miles.
i.e. 1 cm on map = [tex]\dfrac{620}{2.5}\text{ miles}=248 \text{ miles}[/tex]
If the distance on the map between Chicago and Boston is about 3.5 cm.
Then, the actual distance between them = [tex]3.5\times 248 \text{ miles}=868 \text{ miles}[/tex]
Hence, the approximate distance between Chicago and Boston = 868 miles.
NEED HELP PLEASE WITH THIS QUESTION!!
Answer:
It would be D
because you need to multiple 3x3 to get 9 so the answer to your problem is D
Answer:
B
Step-by-step explanation:
So we are trying to find the number that is not between [tex]\frac{\sqrt{16}}{2}[/tex] and 3π on the number line. To do this, lets try to find roughly (exactly if possible) that [tex]\frac{\sqrt{16}}{2}[/tex] and 3π are. Lets start with [tex]\frac{\sqrt{16}}{2}[/tex].
[tex]\frac{\sqrt{16}}{2}=\frac{4}{2}=2[/tex]
So now, by looking at the number line, we can see that the values must be greater than 2. Now lets find 3π. Lets use 3.14 for π (3.14 is actually smaller than the actual value of π):
3(3.14) = 9.42
So we know that the value must be less than 9.42.
We can rewrite answer choice A as 2.08, with is more than 2 and less than 9.42. Therefore, it is between the two numbers on the number line.
While I do not know the exact value of √0.4, I know that it will be less than 1, making it less than 2. Therefore, it is not between the two numbers on the number line, and therefore is our answer.
Lets go through the other two answer choices though.
For C, while 9.37 is close to 9.42, it is still less than 9.42 and greater than 2, and therefore is between the two numbers on the number line.
For D, √9 can be rewritten as 3, which is between the two numbers on the number line.
Even if you did not know that answer choice B, √0.4, was less than 1, you still would have been able to find that B was the correct answer by the process of elimination.
I hope you find my answer helpful.

4(b - 2) = 2(5 - b)
Answer:
3
Step-by-step explanation: cross multiply the solve the equation
Answer:
b=3
Step-by-step explanation:
Use PEMDAS
It says Parentheses first.
4*b, 4*(-2)= 4b, -8
2*5, 2*-b= 10, -2b.
Write the equation out:
4b-8=10-2b
Add 8 to both sides
4b=18-2b
Add 2b on both sides
6b=18
Divide both sides by 6
b=3

Estimate √38 to the tenth's place
I hope this help
Step-by-step explanation:
Square Root of 38 to the nearest tenth, means to calculate the square root of 38 where the answer should only have one number after the decimal point.
Here are step-by-step instructions for how to get the square root of 38 to the nearest tenth:
Step 1: Calculate
We calculate the square root of 38 to be:
√38 = 6.16441400296898
Step 2: Reduce
Reduce the tail of the answer above to two numbers after the decimal point:
6.16
Step 3: Round
Round 6.16 so you only have one digit after the decimal point to get the answer:
6.2
To check that the answer is correct, use your calculator to confirm that 6.22 is about 38.
Answer:

Answer:
23
Step-by-step explanation:
2y=46
y=46/2
y=23
hope this helps!!
Answer:
Y=23
Step-by-step explanation:
If you follow pemdas then you know you have to divide both sides by 2 because its oppisite and when you divide 46 by 2 you get 23 and 2y divided by 2 would be 1y also just known as y and your answer is 23=y
What is the discriminant of the quadratic equation 0 = -x2 + 4x – 2?

O 12
0 24
Answer:
8
Hope this helps!
The discriminant of the given quadratic equation is 8.
What is the discriminant of a quadratic equation?The discriminant determines the type and number of solutions that the equation has.
If the discriminant is positive, the equation has two distinct real solutions. If the discriminant is zero, the equation has one repeated real solution. If the discriminant is negative, the equation has no real solutions.
Given is a quadratic equation -x²+4x-2 = 0, we need to find the discriminant of the quadratic equation,
So,
D = b²-4ac
Here,
a = -1, b = 4 and c = -2
Therefore,
D = 4² - 4(-1)(-2)
D = 16 - 8
D = 8
Hence, the discriminant of the given quadratic equation is 8.

The area of the star shaped surface of this block is 1.2m^2. The thickness of the block is 25cm. What is the volume of the block?
Answer:
volume = 0.30 m³
Step-by-step explanation:
GIVEN:
The area of the star shaped surface of this block is 1.2m^2.
The thickness of the block is 25cm.
FIND:
What is the volume of the block?
SOLUTION:
volume = area x length
where area = 1.2 m²; length = 0.25 m
plugin values into the formula:
volume = 1.2 m² x 0.25 m
= 0.30 m³
therefore, the volume of the star shaped block is 0.30 m³

solve for x:
2x+4=16
Answer:
6
Step-by-step explanation:
2x+4=16
2x=12
x=6
Answer: x = 6
Step-by-step explanation: To solve for x, we must first
isolate the term containing x, which in this problem is 2x.
Since 4 is being added to 2x, we subtract 4
from both sides of the equation to isolate the 2x.
On the left, the +4 and -4 cancels
out and on the right, 16 - 4 is 12.
So we have 2x = 12.
Then just divide both sides by 2 so x = 6.
