Answer:
SR = 5
Step-by-step explanation:
We know that the two lines are equal to each other and thus TS + SR = 13
So, we can simply set the two equations of the first line equal to 13:
x + 2 + 2x - 7 = 13
3x - 5 = 13
3x = 18
x = 6
Now we plug in 6 for x in the SR equation:
2 * 6 = 12 - 7 = 5
<u><em>Answer: A. 30. x=30/ 30=x *The answer should be the positive sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
subtract by 15 both sides of an equation.
x+15-15=45-15
simplify.
45-15=30
30+15=45
45-30=15
x=30 and 30=x
Hope this helps!
Thanks!
Have a great day!
The common difference is d = 4 because we add 4 to each term to get the next one.
The starting term is a1 = 3
The nth term of this arithmetic sequence is
an = a1 + d(n-1)
an = 3 + 4(n-1)
an = 3 + 4n-4
an = 4n - 1
Plug in n = 25 to find the 25th term
an = 4n - 1
a25 = 4*25 - 1
a25 = 100 - 1
a25 = 99
So we're summing the series : 3+7+11+15+...+99
We could write out all the terms and add them all up. That's a lot more work than needed though. Luckily we have a handy formula to make things a lot better
The sum of the first n terms is Sn. The formula for Sn is
Sn = n*(a1+an)/2
Plug in n = 25 to get
Sn = n*(a1+an)/2
S25 = 25*(a1+a25)/2
Then plug in a1 = 3 and a25 = 99. Then compute to simplify
S25 = 25*(a1+a25)/2
S25 = 25*(3+99)/2
S25 = 25*(102)/2
S25 = 2550/2
S25 = 1275
The final answer is 1275
Step-by-step explanation:
let width =x
length=x+14
....
perimeter=96=2*(L+W)
96=2*(X+X+14)
96=4x+28
96-28=4x
68=4x
/4
68/4=x
17=x the width
length = 17+14=31m
....
Check
17+17+31+31=96

Answer: The answer is a parallelogram! I hope this helps you!!
Step-by-step explanation: If only one pair of opposite sides is required to be parallel, the shape is a trapezoid. A trapezoid, in which the non-parallel sides are equal in length, is called isosceles.
