Answer:
2100 ft²
Step-by-step explanation:
1 yard is 3 ft, so 70 yards is (70 yd)×(3 ft/yd) = 210 feet.
The area of the pavement is the product of its length and width:
area = (210 ft)(10 ft) = 2100 ft²
_____
If you keep the units with the numbers as I have done here, you find that the product of (10 ft) and (70 yd) does not have the units of ft². Rather, the units are ft·yd, which is <em>not what the problem is asking for</em>.
Answer:
c
Step-by-step explanation:
i just took the test
First simplify the fractions: 1 1/2 + 3/10
Then add the fractions together: 0.8
Then you have 1.8.
3x+ 4 = 20
First you SUBTRACT 4 from both sides . Since these are inequalities we do reverse PEMDAS (Parentheses , Exponents , Multiply , Divide , Add ,Subtract). Then you will have an equivalent equation of
3x=16
Now we have to isolate X . So we divide 3 by both sides . Which will get 5.3333...
Therefore , The answer will be
The first step in solving the equation is to<u> SUBTRACT </u> from each side . This is an example of the <u>subtraction</u> property of <u>EQUALITY</u>
