Answer:
4(a-2)+a=4a-2 No solution
Step-by-step explanation:
This would never be true. Try plugging in <em>a</em> as 1.
4(1-2)+1 isn't equal to 4(1)-2.
Answer:
38
Step-by-step explanation:
The sum of the measures of the 4 angles is 180°.
m<A + m<B + m<C + m<D = 180
60 + 2x + 3x + 25 = 180
5x + 85 = 180
5x = 95
x = 19
m<B = 2x = 2(19) = 38
Answer: 38
Answer:
0.9964 is the probability that at least one of them meets specifications.
Step-by-step explanation:
We are given the following in the question:
B: Bolts meet the specification
N: Nails meet the specification
P(B) = 96% = 0.96
P(N) = 91% = 0.91
One bolt and one nail are chosen independently.
Thus, we can write
We have to find the probability that at least one of them meets specifications.
0.9964 is the probability that at least one of them meets specifications.
The best way to solve these types of equations is to plug the solution in and see if it checks out.
1/2x+8=10
1/2*-3+8=10
-1.5+8=10
6.5 is not equal to 10
1/2(2*-3-6)=-6
1/2(-6-6)=-6
1/2*(-12)=-6
-6=-6
so d checks out
