Use PEMDAS and the distributive property to solve this problem-
3(x+2)-2(x+1)=8
(3 times x and 3 times 2)
3x+6-2(x+1)=8
(-2 times x and -2 times 1)
3x+6-2x-2=8
Combine like terms (3x/-2x and 6/-2)
x+4=8
Subtract 4 from both sides
x=4
Answer and Step-by-step explanation:
We're given an isosceles triangle, because it says the two side are congruent. That means the base pairs are congruent as well, meaning the other angle (not x) is 75.
We know that the sum of a triangle's angles is 180, so if we subtract the known angles, we can find x.
180 - 75 - 75 = x
30 = x
<u>So, x = 30.</u>

Answer:
Step-by-step explanation:
Easiest way would be to substitute points into the given equations and plot your answers.
E.g. if you substitute points into your first equation you get:
If x = 0, y = -4(0) +2 = 2
If x = 1, y = -4(1) +2 = -2
If x = -1, y = -4(-1) +2 = 6
Etc.
Second equation:
If x = 0, y= -(0) -1 = -1
If x = 1, y = -1 -1 = -2
If x = -1, y = -(-1) -1 = 0
Pretty much just plug in values for x into the equations to find y.
Once you have your points, draw a line :)
Where the two lines intercept would be the solution.
Please upload the question and i will work it out, have a lovely day!
We know that
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m
I apply a rule of three to know the time
if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec
to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes
to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours
1.1576518= 1 hour 9 minutes 27.55 sec
the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)
