The most likely answer is A. A number decreased By 7
38+39+40 = 117.
So the first of the three numbers is 38.
No because 21 ft equals 7 yd
which us bigger than 3 yd
5. 4 rows of circles with 4 columns of circles
6. A Hexagon with 4 circles
To solve a problem like this, we need to start with the innermost parenthesis. Doing that, we get to 4+1, evaluating it giving us 5. This turns our expression into 5 x {3 x [9 - 5]} + 20 ÷ 4 x 2.
Now, the innermost parenthesis is 9-5. Evaluating that gives us 4. Our expression is now 5 x {3 x 4} + 20 ÷ 4 x 2.
Once again, we go to the innermost parenthesis and evaluate whatever is there. This turns our expression into <span>5 x 12 + 20 ÷ 4 x 2.
Now, we can simply use order of operations to compute that the value of the expression is equal to 70. </span>
