Answer:
A) This is correct. The angles of <em>AEB </em>are the angles of <em>DEC. </em>This means that this is true.
B) This is incorrect. This triangle is NOT an isosceles triangle. The angles of an isosceles triangle are supposed to be about 36° for the top angle, and 72° for the other two angles. (At least this is what I was told)
Hope this helps :)
-wait. .___. they both might be true.
According to G oogle: "All the three angles situated within the isosceles triangle are acute, which signifies that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°, which means we can find out the third angle of a triangle if the two angles of an isosceles triangle are known."
(3x-5)+(x+1)=180
x=46
3(46)-5=133

Answer:
(5,-4) and (-5,6)
Step-by-step explanation:
Given:

Solve it. First, express y in terms of x from the second equation:

Substitute it into the first equation:

Answer:
B. 2.75 mph
Step-by-step explanation:
If it took him 2 hours to walk 5.5 miles, 5.5 ÷ 2 = 2.75, which is what he walked in a single hour, meaning he was walking 2.75 mph
Answer:
The price per one pound of almonds equal $2.20/0.65 lb
0.65 pounds of almonds cost $2.20
Step-by-step explanation:
Verify each case
case 1) The price per one pound of almonds equal $2.20/0.65 lb
<em>The statement is true</em>
To find the price per one pound calculate the unit rate
so
$2.20/0.65 lb=$3.38 per one pound
case 2) 2.2 pounds of almonds cost $0.65
The statement is not True
The correct is 0.65 pounds of almonds cost $2.2
case 3) Each bag of almonds weighs 2.2 pounds
Cannot be determined
In the problem there is no information about how much each bag of almonds weighs
case 4) 0.65 pounds of almonds cost $2.20
The statement is True
The point (0.65,2.20) lie to the line of the the graph
