Answer:
2x+y=5
Step-by-step explanation:
y=-2x+5
y-(-2x)=5
y+2x=5
2x+y=5
Answer:
Step-by-step explanation:
Given
Two sides of a triangle; 34 and 12
Required
Determine the range of the third side
Represent the third side with X
To determine the range of the third side; two of the following conditions must be satisfied'
Solving 34 + X > 12
<em>Subtract 34 from both sides</em>
Solving 34 + 12 > X
Solving 12+ X > 34
<em>Subtract 12 from both sides</em>
Write out the results
The first inequality will be discarded because it accommodates negative digits;
<em>So, we're left with</em>
and
This can be rewritten as
and
Combine both inequalities;
Hence, the range of the third length is
So its asking you to find the gravity on earth relative to the gravity on mars.
Set up an equation to figure out the difference between the two gravities
x=.38
I don't know what constant of proportionality is in this context but a ball on mars would weigh .38 the amount that it does on earth.
From the first equation we get
y=4x-15
put the value of y in the second equation
3x+2(4x-15)= -8
3x+8x-30= -8
11x=22
x=2
now put x=2 in any one eqn , say in first
4(2)-y=15
8-y=15
-y=7
y=-7
hope you understand!
3844 x 10²
all you need to do is think about the 10th power
