Answer: -443
Step-by-step explanation:
If she is 362 meters below see level it means she is already down which means the he is -362 . Then she descends 71 meters which means it is also -71 because descending is going down.
Add the two numbers to find her elevation
-362 + (-71) = -433

Please help me. -1/2x+3=-x+7
Answer:
x=8
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-1/2*x+3-(-x+7)=0
simplify 1/2
((0 - (1/2• x)) + 3) - (7 - x) = 0
Adding a whole to a fraction
Rewrite the whole as a fraction using 2 as the denominator :
3 3 • 2
3 = — = —————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-x + 3 • 2 6 - x
—————————— = —————
2 2
(6 - x)
——————— - (7 - x) = 0
2
ubtracting a whole from a fraction
Rewrite the whole as a fraction using 2 as the denominator :
7 - x (7 - x) • 2
7 - x = ————— = ———————————
1 2
Adding up the two equivalent fractions
(6-x) - ((7-x) • 2) x - 8
——————————————————— = —————
2 2
x - 8
————— = 0
2
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x-8
——— • 2 = 0 • 2
2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x-8 = 0
Solve : x-8 = 0
Add 8 to both sides of the equation :
x = 8
Hope this helps :)
Answer:
x=8
Step-by-step explanation:
Original equation: -1/2x+3 = -x+7
First, you must isolate the x value to be alone on 1 side. Steps 1 and 2 do this.
1. Subtract 1/2x to both sides.
This results in:
-0.5x + 7 = 3
Because -x - (-1/2x) = -x + 1/2x = -0.5x
2. Subtract 7 from both sides.
This results in:
-0.5x = -4
Because 3 - 7 = 4
Then, you simply get rid of the -0.5 by multiplication. Steps 3 and 4 accomplish this.
3. Multiply the whole equation by -1
-1(-0.5x) = -1(-4) —> 0.5x = 4
We did this to make it easier to see the equation.
4. Divide the whole equation by 2
2(0.5x) = 2(4) —> x = 8
Your answer is x = 8 because 0.5 times 2 is 1 and 2 times 4 is 7, and you can now ignore the 1 because anything times 1 is itself.
So x=8.
Simplify by combining like terms.
1) 4x + 3p + 3p + 6x
10x + 6p
Step-by-step explanation:Hi there !
4x + 3p + 3p + 6x =
= (4x + 6x) + (3p + 3p)
= x(4 + 6) + p(3 + 3)
= x·10 + p·6
= 10x + 6p

Decide whether the given ordered pair is a solution of the system.
x+y=5
X-y= 3
; (4,1)
Is the given ordered pair a solution to the given system?
A. Yes, because (4,1) makes both equations true.
B. No, because (4,1) makes neither equation true.
C. No, because (4,1) only makes the equation x + y = 5 true.
D. No, because (4,1) only makes the equation x-y = 3 true.
Answer:
A. it is true for both equations
Step-by-step explanation:
x = 4 and y = 1
sub these values into the equations
4 + 1 = 5
4 - 1 = 3

Answer:
8x-3
Step-by-step explanation:
The total perimeter is the length of all the sides of the triangle added together, in this case that is 11x+1. In order to get the length of the one side by itself subtract the other two side lengths from the perimeter. (11x+1)-(x+5)=10x-4. (10x-4)-(2x-1)=8x-3.
5000 bricks of size 20cm × 12cm each are required to pave the path running outside a square field. Calculate the area of the path.
Step-by-step explanation:
20x12= 240cm^2 (the size of one brick)
If there are 5000 bricks then you multiply 240cm^2 by 5000
5000x240= 1,200,000cm^2
(it's a huge number so I'm not so sure about this)
160 cm= mm
250 m =. km

Greetings from Brasil...
Note the graph of the function eˣ (or e⁻ˣ). We conclude that for any value of X, the result will be between 0 and +∞.\
So there is no value for X that the result of m.eˣ (or m.e⁻ˣ) is negative.
So you can answer:
For the equation of the statement of the question, with any value of X, we will always obtain a number greater than zero
S = {X | X∈ ℝ}(OBS: we'll never get zero. We can get very close, but never zero)
Angle Measurements
Identify the relationship (complementary, linear pair/supplementary, or vertical) and find the
value of x in the image below.
(3x + 10)
47°
Answer:
X = 11
Complementary angles
Step-by-step explanation:
Complementary angles are when two angles add up to 90 degrees.
3x + 10 + 47 = 90
3x + 10 = 43
3x = 33
x = 11

In 2010, 465 students went to a certain school. In 2014, 372 students went to the same school by what percent did the number of students decrease
Answer:
20% decrease
Step-by-step explanation:
New value =
465 - Percentage decrease =
465 - (20% × 465) =
465 - 20% × 465 =
(1 - 20%) × 465 =
(100% - 20%) × 465 =
80% × 465 =
80 ÷ 100 × 465 =
