The coordinates of the midpoint of GH¯¯¯¯¯¯¯¯are M(−132,−6) and the coordinates of one endpoint are G(−4, 1).
Answer: (-260, -13)
Step-by-step explanation:
To find the midpoint of a line we find the average of x coordinates and the average of the y coordinates.So since two of the endpoint is already given we could find the midpoint by setting and equation up.
[tex]\frac{-x+(-4)}{2} = -132 x= -260[/tex]
The same way for the y coordinates
[tex]\frac{y+(1)}{2} = -6[/tex] y = -13

Ali has x cards.
Belinda has twice as many cards as Ali.
Charlie has 5 more cards than Ali.
They have a total of 33 cards.
(a) Show that 4x + 5 = 33
(b) Work out the number of cards Ali has.
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
If Ali has x cards, then Belinda has 2x cards.
If Ali has x cards, then Charlie has x+5 cards.
2x (Belinda) + x+5 (Charlie) + x (Ali) = 33 (total)
2x + x+5 + x = 33
Now simplify the equation... x+x+5 can be simplified as 2x+5.
2x+5 plus 2x can become 4x+5.
So their total number is 4x+5.
So 4x+5=33.
You want to isolate the variables and numbers.
To remove the 5 from the left side, subtract 5 from both sides.
4x+5-5=4x - 33-5=28
So the equation now is 4x=28
To remove the 4, divide each side by 4.
4x÷4=x - 28÷4=7
So x equals 7, Ali has 7 cards.

What type of number is 37.9?
A. Real
B . Imaginary
C. Complex
Answer:
A. Real number
Step-by-step explanation:
Fact :Real numbers that include decimal points are known as floating point numbers because the decimal floats within the numbers.
The number 37.9 is a real number which is the correct option (A).
What are real numbers?Real numbers are defined as the value of a continuous quantity that can represent a distance along a line a real number in mathematics. Rational and irrational numbers are both real numbers. Rational numbers such as integers (-7, 0, 4), fractions(5/2,7/2, 4.2), and irrational numbers such as √5, π, etc., are all real numbers.
What is a complex number?A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, and b are real numbers and i is an imaginary number.
Given that number is 37.9
Due to the fact that decimal places can move about within real numbers containing decimal points, these numbers are referred to as floating point numbers.
Hence, the number 37.9 is a real number.

3.48 gallons of milk is sold for $10.16. If you want to buy 10.83 gallons of milk, how
much will you have to pay?
Answer:
$31.62
Step-by-step explanation:
Assuming the price is proportional to the volume, your price will be ...
price/(10.83 gal) = ($10.16)/(3.48 gal)
price = $10.16(10.83/3.48) ≈ $31.62
You will have to pay $31.62.
A map is created of Maricopa County with a scale factor of 1 inch = 2.5 miles. The distance between Phoenix and Fountain Hills is 2.92 inches on the map. Determine the actual distance between the two cities.
Answer:
The actual distance between Phoenix and Fountain Hills is 7.3 miles
Step-by-step explanation:
We note that the scale factor gives the ratio of the map reading to the actual distance reading
The scale factor of the map is 1 inch = 2.5 miles
The distance between Phoenix and Fountain Hills = 2.92 inches on the map
Let the actual distance between Phoenix and Fountain Hills = D, we have;
D/(2.92 inches) = 2.5 miles/inch
Therefore;
D = 2.92 inches × 2.5 miles/inch = 7.3 miles
D = 7.3 miles
The actual distance between Phoenix and Fountain Hills = D = 7.3 miles.
If F is the midpoint of DE, DF = 3x+5 and FE = 5x-19 , Find DF
Answer:
41
Step-by-step explanation:
when there is midpoint it bisects the segment(cuts it in equal halfs)
3x+5 = 5x-19
3x + 24 = 5x
24 = 2x
12 = x
3(12) + 5 =
36 + 5
41
Answer:
The value of segment DF is 41 units.
Step-by-step explanation:
If we know that F is the midpoint of DE, we can conclude that DF and FE have the same value. This lets us set up the following equation:
DF = FE, which when we substitute in our given values is:
3x + 5 = 5x - 19
The next step is to solve this equation. We should start by subtracting 3x from both sides of the equation.
5 = 2x - 19
Then, we can add 19 to both sides of the equation.
24 = 2x
Finally, we can divide both sides by 2.
x = 12
Now that we have a value for x, we need to find the length of DF. To do this, we can just plug in our value for x into the given expression for DF and simplify.
DF = 3x + 5 = 3(12) + 5 = 36 + 5 = 41
Therefore, the correct answer is 41.
Hope this helps!

You have $138 in a savings account and save $12 per week. Your friend has $98 in a savings account and saves $17 per week. How many weeks will it take for you and your friend to have the same balance?
Solution
Provided :-
• I have $138
• I save $12 per week
• Friend have $ 98
• He saves $17 per week
Let the number of weeks required to have same balance be x
→ 138 + 12x = 98 + 17x
→ 138 - 98 = 17x - 12x
→ 40 = 5x
→ x = 8
So we need 8 weeks
Answer: 8 weeks
Step-by-step explanation:
Let x = the number of weeks
138+12x=98+17x
40+12x=17x
40=5x
x=8

Simplify the following algebraic expression:
- 2(x - 1) + 3(6x – 7)
Answer:
16x-19
Step-by-step explanation:
Step-by-step explanation:
Hey, there!
While simplifying the algebraic expression you must remember: multiply or take LCM first and then add or or subtract like terms then if there is division then you may cut like terms of numerator and denominator.
Here,
[tex] - 2(x - 1) + 3(6x - 7)[/tex]
Is given.
Multiply (x,-1) by -2 and (6x,-7) by 3.
[tex] (- 2x + 2) + (18x - 21)[/tex]
open brackets.
[tex] = - 2x + 2 + 18x - 21[/tex]
Add and subtract like terms.
[tex] = - 2x + 18x + 2 - 21[/tex]
[tex] = 16x - 19[/tex]
Therefore, the answer is (16x - 19).
Hope it helps.....

Answer:
K = [tex]\frac{4r}{n} -a[/tex] n [tex]\neq 0[/tex]
Step-by-step explanation:
We have our equation [tex]r = \frac{n}{4} (a+K)[/tex] and are looking for K
First we have to switch sides :
[tex]\frac{n}{4} (a+K) = r[/tex]
Since we have a denominator of 4, we multiply both sides by 4 :
[tex]n (a+K) = 4r[/tex]
We then divide both sides by n :
[tex]a+K = \frac{4r}{n} ; n\neq 0[/tex]
Subtract a from both sides :
[tex]K = \frac{4r}{n} -a; n\neq 0[/tex]

Connor is driving on a long road trip. He currently has 9 gallons of gas in his car. Each hour that he drives, his car uses up 2 gallons of gas. How much gas would be in the tank after driving for 3 hours? How much gas would be left after
Answer: 3 gallons
Step-by-step explanation:
From the question, we are informed that Connor is driving on a long road trip and currently has 9 gallons of gas in his car. We are also told that for every hour that he drives, his car uses up 2 gallons of gas.
After driving for 3 hours, his car would have used:
= 3 × 2 gallons
= 6 gallons of gas
Amount of gas left will be:
= 9 gallons - 6 gallons
= 3 gallons
Can anyone help?i been going at this for a while and i still cant figure it out, i dont really understand how to even get the answer id appreciate some help :D
Answer:
A) 44.26
B) 9.43
C) (2.5,3.5)
D) OH
E) 26.26
Step-by-step explanation:
Let’s figure out the lengths first. Three are straight line, so are easy:
HE=9, SE=11, SU=9
The other two, you need to use the distance formula or Pythagorean Theorem. OH=8²+5²=c² = 64+25=c² = 89=c² = √89 = 9.43
OU=3²+5²=c² = 9+25=c² = 34=c² = √34 = 5.83
Now we can start answering the questions.
A) 9+11+9+9.43+5.83=44.26
B) 9.43
C) You already have: (2.5,3.5)
D) OH=9.43. EH=9. OH is longer.
E) HU is 11. OH is 9.43. OU is 5.83. 11+9.43+5.83=26.26
