Answer:
Dave worked 60 hours.
Step-by-step explanation:
Let's assume that Dave worked a total of 
hours.
Since Kate worked 5 hours less than Dave: 
And Sarah worked 10 more hours than Dave: 
Combined, the three siblings worked 185 hours.
Dave worked 60 hours,
Kate worked 55 hours and Sarah worked 70 hours.
To check:
55 + 60 + 70 = 185 hours

The 2 legs of the triangle could be 12 and 9 (they would fit the Pythagoras theorem).
The first choice fits these reuirements
Answer is (-5, 6), (-5, -6) (4,-6)
Answer:
690
Step-by-step explanation:
Let
hayden have "h"
uri have "u"
and
willow have "w"
Hayden & Uri have 1250. we can write:
h + u = 1250
Hayden & Willow have 830, so we can write:
h + w = 830
Uri has 4 times than Willow, so we can write:
u = 4w
Putting 3rd equation in first, we get:
h + u = 1250
h + 4w = 1250
Now, we take 2nd and 4th equation, which are:
h + w = 830
h + 4w = 1250
Multiplying this first one with -1, gives us:
-1 * [h+w=830] = -h - w = -830
Now we add this up with 4th equation. Shown below:
- h - w = - 830
h + 4w = 1250
----------------------
4w - w = 1250 - 830
3w = 420
w = 420/3
w = 140
We know u = 4w, so u = 4 * 140 = 560
u = 560
Also, we know h + w = 830, so
h + 140 = 830
h = 830 - 140
h = 690
Thus Hayden has 690
Answer: If every quadrilateral has at least two congruent sides, then an obtuse angle is an quadrilateral.
Step-by-step explanation:
A counterexample is basically the opposite of a conditional statement. So the Hypothesis is true but the conclusion is false. An obtuse triangle has different size sides and congruent sides means same size sides. Hope this helps!!!! Let me know if you need further explanation.
