Hello!
As you can see, there are 9 total activities. As you can see, 6 of them burn more than 400 calories. This gives us the probability 6/9.
Therefore, our answer is C) 6 out of 9
I hope this helps!
Answer:
B. 2, 4, 5, 7
Step-by-step explanation:
6x<48
Divide by 6 on both sides:
x < 8 (excluding 8)
You can test values greater than 8, and if it yields false, then try different numbers.
Hope this helps!
∠A=66
∠B=x
∠C=?
∠D=117
Ok, lets sovle for ∠C first.
180-117=∠C
63=∠C
Ok, now we can solve for ∠B or x.
66+63+x=180
129+x=180
-129 -129
x=51
Hope this helps! :)
I believe this question should be from an I-Ready test. The answer would be $20.00. Because 70% of 20.00 is 14
We know that x > 2 ( or : x ≠ +/- 2 )
We have to factorize the numerator and the denominator:
x² - x - 6 = x² - 3 x + 2 x - 6 = x ( x - 3 ) + 2 ( x - 3 ) = ( x - 3 ) ( x + 2 )
x ² - 4 = ( x - 2 ) ( x + 2 )
