Answer:
Difference between the actual number of counties and Zane's rounded number is:
4
Step-by-step explanation:
There are 254 counties in Texas.
Zane rounds the number of counties to the nearest ten.
According to Zane number of countries in Texas=250
Difference between the actual number of counties and Zane's rounded number= 254-250
=4
Hence, difference between the actual number of counties and Zane's rounded number is:
x = 18
3x-10+25+x+15=180
4x+30=180
4x=180-30
4x=150
x=37.5
1.2
90 in²
First,check the figure I provided .
Area of the figure = area1 + area2 + area3 + area4
= (3×2) + (7×7) + (7×2) + (7×6)÷2
= 6 + 49 + 14 + 21
= 90
