Answer:
Which expression is equivalent to 8.7u+1.4+3.2u−9.5 ?
By multiplying and division
Answer:
Percentage error is 0.0024 %
Step-by-step explanation:
Initial average distance between Earth and moon = 384467 km
Distance measure by the scientist = 384476 km
Total variation in the distance calculation = 384476 – 384467 = 9 km.
Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.
Percentage error = ( 9 / 384467 ) × 100 = 0.0024 %
X will represent unknown
2x-4<3x
treat the < sign as a = sign
2x-4=3x
subtract 2x form both sides
-4=x
put the < sign back
-4<x
-4 is less than than x or
x is greater than -4
Answer:
Step-by-step explanation:
180/4 is 45 so you could say the farmer plants 135 Acers of corn and only 45 of wheat
3x+y=180
Hope this helped.
