Answer:
X=4
Step-by-step explanation:
The larger one should be 29*1016. Round 1016 down to 1000.
You get 29000 when you do that.
6 * 1020 is roundable to 6*1000 which is 6000
If you round 29000 to 30000 then 29*1016 should be 5 times larger than 6 * 1020
Check it out.
29 * 1016 = 29464
6 * 1020 = 6120
When you divide the smaller into the larger, you get 4.18 which is in the same ball park as 5.
Estimating is a skill you need when you are shopping and when you are writing tests. If you need to know if 4.18 is a good answer when a rounded answer is 5, you know you've done the work properly.
Rounding should permit you to get an answer in your head.
Distribute 3/8 to m and 1 so now the equation should be 1/4m + 3/4m - 3/8m + 3/8
then add 1/4m 3/4 to get m. the equation should now look like m - 3/8m + 3/8
m is 1m but the one is invisible so subtract 3/8 from 1 now the equation should look like 5/8m + 3/8
final answer: 5/8 + 3/8
Answer:
112
Step-by-step explanation:
add both bases the multiply by the height
Interior angles of a triangle, when added, = 180
so < A + < B + < C = 180
41 + 90 + < C = 180
131 + < C = 180
< C = 180 - 131
< C = 49
< C + < D + < E = 180.....because when added they form a line
49 + 32 + < E = 180
81 + < E = 180
< E = 180 - 81
< E = 99 <======
