For a system of equations such as this, add both of the equations together. The d values will cancel each other out, making 2e=-4. This means that e=-2. If you plug this into one of the equations, you will have d + (-2) = 1. Isolate the variable by adding -2 to both sides: d=3. Written in the format described above (d,e), your answer is (3, -2).
The answer would be one because .9998 would round the 9 to a 10 which would round the second 9 and then the third nine to make 1

Answer:
The triangle is not acute because 2² + 4² < 5².
Step-by-step explanation:
21.50 x 25 = 537.50
10.75 x 5 = 53.75
537.50 + 53.75 = 591.25
