Answer:
The number of test required is: 55
Explanation:
Using combination formula:
n!/x!(n-x)!
= 11!/2!(9)!
= 55
Answer:
<DAB= 98
Step-by-step explanation:
Remark
I think you are supposed to assume that this is a parallelogram. In that case the two labeled angles are intended to be equal (one of the properties of a parallelogram).
Equation
2x + 36 = 3x - 5 Add 5 to both sides
2x + 36 + 5 = 3x - 5 + 5 Combine
2x + 41 = 3x Subtract 2x from both sides
2x - 2x + 41 = 3x - 2x Combine
41 = x
Answer
<DAB = 2x + 36
<DAB = 2*41 + 36
<DAB = 82 + 36
<DAB = 98
Answer:
y = 3
x = 2
Step-by-step explanation:
-5x + 4y = 2
9x - 4y = 6
Sum both eq.
-5x + 9x = 4x
+4y - 4y = 0
2 + 6 = 8
then:
4x + 0 = 8
4x = 8
x = 8/4
x = 2
from the first eq.
-5x + 4y = 2
-5*2 + 4y = 2
-10 + 4y = 2
4y = 2 + 10
4y = 12
y = 12/4
y = 3
Check:
from the second eq.
9x - 4y = 6
9*2 - 4*3 = 6
18 - 12 = 6
Answer: 15856
Step-by-step explanation: 166786.9963 - 150930.6256
= 15856.3707
= $15856
Answer:
x = 17
Step-by-step explanation:
-2x+8-6=-32
lets isolate the x variable:
-2x=-32-8+6
-2x = -34
x= -34/-2
x= 34/2
x= 17
