Answer:
7x² - 40x - 12 = 0
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable. After doing that, then apply the Quadratic Formula to the listed answer choices to see if they give you the exact same x-intercepts, EXCEPT for this one, where you can easily factor this one. It is "process of elimination". Sometimes you have to try it.
Answer:
b = 44
Step-by-step explanation:
b + 90 + 46 = 180 (Supplementary Angles)
b = 180 - 90 - 46
b = 44
Answer:
290 adults and 341 children
Step-by-step explanation:
Doubles are adding the same number together, as with 5+5=10.
With doubles +1, the numbers must be in beside each other in counting order going up or down (ex: 4, 5, 6 and 9, 8, 7). Do the SMALLEST number, double it, then add one. So, 9+8 would be 8+8=16, +1=17. You must know your doubles facts before this strategy is useful.
