First multiply -1 on the top to cancel X
It will give u:
-X+Y=-5
X-2Y=3 which gives u
y=2
Now, plug in the y (one of the equation it doesn’t matter which one) to solve for X
X-2=5
X=7
Answer:
1. d < 10
Step-by-step explanation:
Hi there !
8 > d - 2 | +2
8 + 2 > d - 2 + 2
10 > d
d < 10
Good luck !
Answer:
33
Step-by-step explanation:
We know that PS and QR are the same size since we are working with parallel sides of a parallelogram. We can write an equation and solve for z.
5z + 3 = 6z - 3
~Subtract 3 to both sides
5z = 6z - 6
~Subtract 6z to both sides
-z = -6
~Divide -1 to both sides
z = 6
Now, find the length of QR with what we found for z.
6z - 3
6(6) - 3
36 - 3
33
Best of Luck!
Answer:
n = 98
Step-by-step explanation:
8/11 x (n - 10) = 64
multiply both sides of the equation by 11/8
11/8 x 8/11 x (n-10) = 11/8 x 64
reduce the numbers with greatest common divisor 11
1/8 x 8 (n-10) = 11/8 x 64
n - 10 = 11 x 8
multiply the numbers
n - 10 = 88
so then you add the numbers
n = 88 + 10
n= 98
Answer:
B. 100π
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
The radius is 5
SA = 4 * pi * r^2
SA = 4 * pi * 25
SA = 100 pi
