Answer:
0.58
Step-by-step explanation:
20.88/36 = 0.58
12 *16 = 192
1/2 *20*10 = 100
192 +100 = 292 square units
Answer:
there are four significant figures
Step-by-step explanation:
zeros to the right of a non zero digit are ambiguous
1. {2x−3y=9
{3x+5y=4
2. {(2x−3y=9)×5
{(3x+5y=4)x3
3. {10x-15y=45
{9x+15y=12
4. (10x-15y=45) + (9x+15y=12)= (19x=57)
5. (19x=57)÷19
6. x=3
7. 2(3)-3y=9
8. 6-3y=9
9. -3y=9-6
10. (-3y=3)÷(-3)
11. y=-1
Answer: x=3 and y=-1
Answer:
30
Step-by-step explanation:
- How much was the decrease from Figure A to Figure B (let x be the decrease): 45x = 27
- Divide each by 45 to cancel out the 45 next to x. It should now look like this: x = 3/5
- To find x, we would normally multiply x by 3/5, but because we don't have x, we just DIVIDE 18 by 3/5: 18 ÷ 3/5 = 30
- So, x = 30
I hope this helps!
