This is direct proportion - it takes less time to run 15 miles than 50 miles. Show the comparison:
<span><span>5060</span>=<span>15x</span></span>
<span>50x=60×15</span>
<span>x=<span><span>60×15</span>50</span></span>
<span>x=18</span>minutes
If m∠F=40° then m∠D=40°
m∠F, m∠D and m∠G have to be 180° together in order to form a triangle
So m∠G = 180° - 2×40° = 100°
One line is cutting m∠G in half and we get m∠EGF and m∠EGD
We want to know how much m∠EGF is so...
m∠EGF=100°÷2=50°
Now we have m∠F which we can name m∠EFG and we have m∠EGF
Together with m∠FEG they form a triangle so that means together they have the value of 180°
m∠FEG=180°-40°-50°=90°
And because you have parralel lines m∠FEG=m∠CBE
And m∠ABE=180°-m∠CBE=90°
That is if I understand this correctly
24.95 + 3.95x < = 76.30
3.95x < = 76.30 - 24.95
3.95x < = 51.35
x < = 51.35/3.95
x < = 13....the greatest number is 13
Answer:
5x² - 35x + 50
Step-by-step explanation:
distribute 5 to (x-2) to get:
5x-10
now multiply (5x-10) and (x-5) to get:
5x² - 25x - 10x + 50
combine like terms to get:
5x² - 35x + 50
3x+y=-5
12x+5y=27
Let y =-5-3x
Insert y into equ.2
12x+5(-5-3x)=27
12x-25-15x=27 den rearrange
-3x=2 den x =-2/3
Den put xinto equ 1
3(-2/3)+y=5
-2+y=5(collect like terms)
Y =7
