Answer:
x ≤ 42 dollars
Step-by-step explanation:
Deon will buy at most 7 pounds, and we know that it costs 6 per pound, so we multiply 7 and 6 to get 42. Deon will not buy over 7 pounds, so that means less than or equal to.
Equilateral triangles have three equal angles, so we right away know that x=60º. Then, we just solve (3(60)-70)º, which is 110º, for the answer.
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.
Two angles adjacent angles that add up to 180 degrees
Answer: -418, 728, 446, -429, 1159, -696
Step-by-step explanation:
1. .
2. .
3. .
4. The sum of 429 and 429 is . We need to subtract this from 429, so .
5. The sum of 510 and 319 is . Subtracting -330, we get .
6. Call the unknown number "". Then , so . (Think about it.)
