D) Art is in a hot -air balloon 230 feet off the ground. The balloon climbs another 230 feet. How high off the ground is the hot-air balloon?
Answer:
C
Step-by-step explanation:
Hope this helps!!!!!!!
Answer:
C
Step-by-step explanation:
24.75+(-24.75)= 0
Though I would have believed A would be correct if not for the fact of how far he walked which would be 4.6 miles
B is similar you can't become the same age as someone if the are older than you
D is just 230+230=460
Wen says the function is continuous, because the number of people is unlimited. Is Wen right or wrong?
Answer Wen is incorrect. The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.

Answer:
I don't know if you have given the full question.
Step-by-step explanation:
but from what you have typed I understood that ( -x ) = - ( x)
positive × positive = positive
negative × negative = positive
positive × negative = negative
so from this we derive -x = -x ( when we open the bracket negative 1 is multiplied to x)
9. A tailor has 23 metres of cloth. She wants to make 7 baju kurung of the same size. She then has 2 metres of cloth left. How many metres of cloth did she use to make each baju kurung?
Answer:
The tailor used 3m per baju kurung.
Step-by-step explanation:
The tailor began with 23m of cloth and at the end had 2m of cloth left. You calculate how many meters of cloth she used all together by subtracting 2 from 23:
23m - 2m = 21m
Then you find out how many meters she used per baju kurung by dividing 21 by 7:
21m / 7m = 3m

To get to the camp in time, tourists had to go with a speed 4km/h. They went with that speed half of the road, but then they drove with a bus and arrived to the camp 2h 20min before the planned time. How many kilometers did tourists drive with the bus, if the speed of the bus was 60km/h?
Answer:
it is solved at jemrare dot com
Step-by-step explanation:
This problem can be solved using distance formula;
s=vt
Here we suppose;
Speed of Tourists=v1=4 km/h
speed of bus=v2=60km/h
Total time to be taken by the tourists to reach the camp without bus=t
Time taken by tourists when bus used=t-2h20min=t-140min
let the total distance is ‘x’ but half is travelled without bus and other half by bus!
for first half distance=s1 =x/2
for second half distance=s2=x/2
Using s=vt formula for first half;

12/x=45
What would x equal
Answer:
=4/15
=0.26
Step-by-step explanation:
Answer:
x = 4/15
Step-by-step explanation:
Step 1: Multiply both sides by x.
[tex]\frac{12}{x} * x = 45 * x[/tex] [tex]12 = 45x[/tex] [tex]45x = 12[/tex]Step 2: Divide both sides by 45.
[tex]\frac{45x}{45} = \frac{12}{45}[/tex] [tex]x = \frac{4}{15}[/tex]Therefore, x = 4/15.

Mahni plans to spend the next 12 weeks saving some of her income. She will save $x a week for the first 6 weeks and then $(2x − 30) a week for the following 6 weeks. If she managed to save $213 in the first six weeks, how much did she save in total over 12 weeks? Explain correctly how to do this to get Brainliest ANSWER
$x=213$
For first six weeks she saved 213$
Now
For next 6weeks

Step-by-step explanation:
If 4x - 9 = 35,
find the value of 6x + 4
Step-by-step explanation:
4x=44
x=11
6x+4= 6*11+4= 70
Answer:
6x+4=70
Step-by-step explanation:
To solve this, first, we need to know what x is. To do this, we need to solve the equation:
4x-9=35
The first step to solving this is to add nine to both sides, since we need to do the inverse of subtraction to get our answer.
4x-9+9=35+9
4x=44
Now, do the inverse of multiplying by four, which is dividing by four, to both sides.
4/4x=44/4
x=11
Now that we know what x is, we can find the value of 6x+4. Simply plug in 11 for x.
6(11)+4
66+4
70
Our answer is 70.
х+ 5y = 16
х+ Зу = 10
x=?
y=?
Answer:
x=1 y=3
Step-by-step explanation:
x+5y=16
x+3y=10
2y=6
y=3
x+15=16
x=1
verify
1+9=10
Answer:
x = 1 , y = 3
Step-by-step explanation:
x + 5y = 16 → (1)
x + 3y = 10 → (2)
Subtract (1) from (2) term by term to eliminate x
0 + 2y = 6
2y = 6 ( divide both sides by 2 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 5(3) = 16
x + 15 = 16 ( subtract 15 from both sides )
x = 1
what are the solutions of x^2-4x+5=0
A. x=2+i/3 or x=2-i/3
B. x=1+i/2 or x=1-i/2
C. x=3+i or x=3-i
D. x=2+i or 2-i
Answer:
Should be D.
Step-by-step explanation:
Because you can't factor the equation you use the quadratic formula. By using it you should get 4 plus or minus the square root of -4 all over 2. Simplified would be 2 plus or minus i

pls helpppppppppppppppp Which value of y makes the equation 12y−3=5 true?
y is equal to 2
y is equal to 1
y is equal to 2 thirds
y=13
Answer:
y = 2/3
Step-by-step explanation:
so 12y-3=5, add the 3 to the 5 to get 12y=8. Then divide the 12y by 12 and the 8 by 12. In so you geet y=2/3
Answer:
y is equal to 2 thirds (y = 2/3)
Step-by-step explanation:
12y − 3 = 5
Substitute the given options to see which one will provide a true statement:
If y = 2:
12y − 3 = 5
12(2) − 3 = 5
24 − 3 = 5
21 = 5 (False statement, so it's not the right answer).
If y = 1:
12(1) − 3 = 5
12− 3 = 5
9 = 5 (False statement).
If y = 2/3:
12(2/3) − 3 = 5
8 - 3 = 5
5 = 5 (True statement).
If y = 13:
12(13) − 3 = 5
156 - 3 = 5
153 = 5 (False statement).
Therefore, the correct answer is: y = 2/3.
Find two numbers if their ratio is 9:11 and their difference is 6 THERE ARE TWO ANSWERS!!
Step-by-step explanation:
x, y are the 2 numbers.
x/y = 9/11
x - y = 6
x = y + 6
now we use that in the first equation
(y + 6)/y = 9/11
y + 6 = 9y/11
11y + 66 = 9y
2y = -66
y = -33
x = y + 6 = -27
but the second equation could also be
y - x = 6
then
x = y - 6
and that in the first equation leads to
(y - 6)/y = 9/11
y - 6 = 9y/11
11y - 66 = 9y
2y = 66
y = 33
x = y - 6 = 27
Find cos O if sinO = sqrt2/2 is in the second quadrant
Answer:
D. [tex]-\frac{\sqrt{2} }{2}[/tex]
Step-by-step explanation:
So, on a regular coordinate plane, coordinates are written (x,y)
well, in trig, coordinates are written (cosθ, sinθ).
if sinθ=[tex]\frac{\sqrt{2} }{2}[/tex] in the second quadrant, then look for the "y-value" that says
if you don't have a unit circle to look at, then it helps to know that the fraction [tex]\frac{\sqrt{2} }{2}[/tex] is ONLY found with ITSELF OR THE NEGATIVE OF ITSELF. it is never paired with another number.
this means that this number will only be seen in the coordinates
[tex](\frac{\sqrt{2} }{2} ,\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})\\(\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})[/tex]
use this knowledge along with knowing the signs in each quadrant:
Q1: (+,+)
Q2: (–,+)
Q3: (–,–)
Q4: (+,–)

6) Identify the graphed linear equation. A) y = 2 5 x - 5 B) y = 1 5 x - 5 C) y = 2 5 x + 5 D) y = 1 5 x + 5
Answer: There is no graph that I can see. I created one showing each line.
Step-by-step explanation: A straight line has the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is zero). The two lines with slope 25 will rise much more quickly than the ones with a slope of 5. You could eliminate two lines based on that alone. With the two remaining lines, look at the y-intercept seen on the graph (the value of y when x=0). The options are 5 and -5. The correct line will be the one with the expected intercept.
