Answer:
Step-by-step explanation:
Isolate x on one side of the equation.
First, do parenthesis.
4(2+3)
Add.
3+2=5
Multiply.
4*5=20
Rewrite the equation problem.
x+20<5x
Secondly, subtract 20 from both sides.
x+20-20<5x-20
Solve.
x<5x-20
Thirdly, subtract 5x from both sides.
x-5x<5x-20-5x
Solve.
5-1=4
-4x<-20
Then, multiply -1 from both sides.
(-4x)(-1)>(-20)(-1)
Solve.
(-4x)(-1)=4x
(-20)(-1)=20
4x>20
Divide by 4 from both sides.
4x/4>20/4
Solve.
20/4=5
x>5
The solutions is 5, therefore, the correct answer is x>5.
Answer:
y=3x +25
Step-by-step explanation:
First calculate the slope:
m = (y1 - y2)/(x1-x2)
m = (49 - 13)/(8-(-4))
m= 36/12 = 3
so we have
y = 3x + b
subtitute a point:
49=3(8) + b
b=25
the equation is y=3x +25
Answer:8 lilies and 12 tulips; total of 20 flowers.
Step-by-step explanation:
8 lilies for $3 each equals $24. 12 tulips for $2 each equals $24. Add that together and the total for the bouquet is $48.
we know that
If V is the midpoint of SU
then
SV=VU
substitute the given values
2x+18=8x-6
solve for x
8x-2x=18+6
6x=24
<h2>x=4</h2>
Find SV
SV=2x+18
SV=2(4)+18
<h2>SV=26 units</h2>
so
<h2>VU=26 units</h2>
and
SU=2SV
SU=2(26)
<h2>SU=52 units</h2>
