Answer:
(-2.5, -3.5)
Step-by-step explanation:
In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.
1 + (-6) = -5
-5/2 = -2.5
1 + (-8) = -7
-7/2 = -3.5
pleaseeeeeeee help me

Step-by-step explanation:
i need to know the answer as soon as possible.
0.35p
Because the price also indicates percentage
Answer:
p - 0.35, so C.
It's not A because that's the regular price times the percentage off.
X divided by 11 equals 10 divided by 12 what’s x
Answer:
x/11 = 10/12
x = 10*11/12= 55/6
Step-by-step explanation:
[tex] \huge \pink {\tt { \frac{x}{11} = \frac{10}{12}}} [/tex]
By cross multiplication, we get
12x = 110
or, x = 110/12 = 55/6
Answer: x = 55/6Solve for X: -7

ANSWER THIS QUESTION WITH WORKING PLEASE :>!!!
Step-by-step explanation:
y + 65°= 180° (Being co-interior angle)
y = 180° - 65°
y = 115°
Next we will find of the next co-interior angle which is A and D
(2x - 10)° + (3x + 20)° = 180° ( Same reason)
Now we will keep the like ones together.
2x° + 3x° - 10° + 20° = 180°
5x° + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 170°/5
x = 34°
Now we need to find (2x - 10)° and (3x + 20)°
(2x - 10)°
=(2×34-10)°
=(68-10)°
=58°
(3x + 20)°
=(3×34-20)°
=(102-10)°
=92°
Ally's hair grew from 10 10 \frac{3}{4} 4 3 inches to 13 13 \frac{1}{4} 4 1 inches over 5 months. At what rate did Ally's hair grow per month?
0.5 inches a month.
I believe you subtract 13 1/4 by 10 3/4 = 2 1/2.
Then you divide by 5.
can someone help me with this please
Answer:
I think the answer is E.
Step-by-step explanation:
-3 -4= -7 and that's less than nine.
if x was 3 it would be -7 + 3 = -4 which is still less than nine
if x was -11 it would be -7 -11 = -18 which is also lower than nine
if x was -3 it would be -7 -3 = -10 that's less than nine as well
Answer:
I only
Step-by-step explanation:
I) 3
9 > -3 - 4(3)
9 > -3 - 12
9 > -15
9 is great than -15 so the value of 3 works.
II). -11
9 > -3 - 4(-11)
9 > -3 +44
9 > 41
9 is actually less than 41 so the value of -11 does not work
III). -3
9 > -3 - 4(-3)
9 > -3 + 12
9 > 9
9 is equal to 9, not greater than so the value of 3 does not work

Step-by-step explanation:
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(3-9)^2+(6-2)^2} \\d= \sqrt{(-6)^2+(4)^2} \\d= \sqrt{(36)+(16)} \\d= \sqrt{52} \\d=2 \sqrt{13}[/tex]
How do you solve a problem involving squeeze theorem?
Answer:
Step-by-step explanation:
if two functions are squeezed together at a particular point , then any function trapped between them will get squeezed to that point. the squeeze theorem deals with limit value , rather than function value. the squeeze theorem sometimes called Pinch Theorem.
Review the following equation. Redo the work for the equation. What is the
value of x?
2(x + 1) = x - 4(x-2)
2x 2 = x-4(x-2)
2x2 = x - 4x - 8
2x - 2 =-3x - 8
-6 = -5x
-6/5 = x
What is the answer?:
x= 6/5
x= 5/7
x= 7/5
x= -3/5
HELP!! -5/8 - (-4/3) = x What is x?
Answer:
x = [tex]\frac{17}{24}[/tex]
Step-by-step explanation:
Given
- [tex]\frac{5}{8}[/tex] - (- [tex]\frac{4}{3}[/tex] ) = x
Note that - (- [tex]\frac{4}{3}[/tex] ) = + [tex]\frac{4}{3}[/tex] , thus
- [tex]\frac{5}{8}[/tex] + [tex]\frac{4}{3}[/tex] = x
Multiply through by 24 ( the lcm of 8 and 3 ) to clear the fractions
- 15 + 32 = 24x
17 = 24x ( divide both sides by 24 )
[tex]\frac{17}{24}[/tex] = x
Using a portion of her savings as a down payment, Sarah bought a new car in order to commute to her new job, reducing her savings account to only $2220. From her expendible income of $2440, essential expenses (fixed) are $1010 per month, essential expenses (flexible) are $500 per month, and nonessential expenses are $430 per month. Sarah has decided to reduce her nonessential expenses for 9 months to only $230 per month, in order to build her savings back up to $5820. Then she will return her nonessential expense budget to the original $430 per month. Choose the reason or reasons why Sarah would spend less money every month temporarily in order to have this fund. I. She realizes the importance of having an emergency fund. II. She wants to build up her retirement account. III.She understands that reducing expenses can increase savings. a. I b. II and III c.

Faith lost 2 1/2 pounds in 10 days. If
Faith lost the same amount of pounds each
day, how much weight did Faith lose per
day?
Please help me
Answer:
1/4 pound
Step-by-step explanation:
2 1/2 divided by 10
=
1/4
or
5/2 divided by 10
=
1/4
Answer: 1/4 lbs
Step-by-step explanation:
To find weight lost each day, you have to divide total weight lost 2 1/2 lbs by total number of days 10.
(2 1/2) / 10 = 5/2 * 1/0 = 1/4 lbs lost each day

Answer: x=-7
Step-by-step explanation:
1) The angles of a triangle are equal to 180
2) Add your angles together and set them equal to 180 like this:
x+59+x+51+84=180
3) Combine like terms:
2x+ 194 =180
4) Subtract 195 from both sides:
2x+ 194 =180
- 194 -194
2x = -14
5) Divide by 2 on both sides
2x= -14
/2 /2
x= -7

I need help solving 8g+10=35+3g. Please help!!
Answer:
g = 5
Step-by-step explanation:
Step 1: Write out equation
8g + 10 = 35 + 3g
Step 2: Subtract 3g on both sides
5g + 10 = 35
Step 3: Subtract 10 on both sides
5g = 25
Step 4: Divide both sides by 5
g = 5

C(2.76, 310) means you want to evaluate the expression for g=2.76 and d=310. Put those numbers where the variables are and do the arithmetic.
[tex]C(2.76,310)=\dfrac{2.76\cdot 310}{25}=\dfrac{855.6}{25}=\boxed{34.224}[/tex]
QUESTION 8 A motorboat leaves a harbor and travels at an average speed of 6 mph towards a small island. Two hours later, a cabin cruiser leaves the same harbor at an average speed of 12 mph toward the same island In how many hours after the cabin cruiser leaves the harbor will it be alongside the motorboat?
Answer:
2 hours
Step-by-step explanation:
Distance = rate × time
That is,
d=rt
Let
t = time (hours) cabin cruiser traveled
t + 2 = time (hours) motorboat traveled
motorboat = 6 mph
Cabin cruiser =12 mph
Motorboat distance
d=rt
d = 6(t + 2)
Cabin cruiser distance
d=rt
d = 12(t)
Equates the two distance
6(t + 2) = 12t
Open bracket
6t + 12 = 12t
12 = 12t - 6t
12 = 6t
Divide both sides by 6
t = 12 / 6
= 2
t = 2 hours
The cabin cruiser will be alongside the motorboat in 2 hours
Explain what mistake is made in the following false statement: 3(x+4)(x+7)=(3x+12)(3x+21)
Answer: The 3x+21
Step-by-step explanation:
3(x=4) = (3x+12) The (3x+12) is being multiplied by (x+7) and the 3 should only be distributed to (x+4) which meant the the equation when simplified should have become (3x=12)(x+7).
valuate y = 3x - 5 when x = 6.
Answer:
y= 3x-5

what is the answers to
8x-2-5x+7=
Answer: 3x +5
Step-by-step explanation:
Group the variables first 8x-5x is 3x. Then look at the numbers -2+7 is 5.
You can't combine letters and numbers so it's as far as you can go.
Solve the two-step equation.Analyze the solution shown.
1. –|–x| = 7: given
2. |–x| = –7: multiplication property of equality
3. –x = 7 or –x = –7: definition of absolute value
4. x = –7 or x = 7: multiplication property of equality
5. Check: –|–(–7)| = 7, –7 ≠ 7
–|–7| = 7, 7 = 7
Negative times negative is positive.
Determine the flaws in the solution.
The multiplication property of equality in Step 2 should result in |x| = 7.
The definition of absolute value is applied incorrectly. There is no solution.
The reason in Step 4 should be the addition property of equality.
The multiplication property of equality in Step 4 should result in only x = 7.
In evaluating the solutions, the absolute value should be simplified first to get a positive value.
Answer:n evaluating the solutions, the absolute value should be simplified first to get a positive value.
The definition of absolute value is applied incorrectly. There is no solution.
