The best estimate of the lateral area of the cube with edges that are 2.1 inches long is 4.2
Answer:
9 3/4
Step-by-step explanation:
Strategy: first cancel the fraction part of the mixed number, then subtract the remaining fraction from the integer obtained.
10 1/2 - 3/4 = 10 1/2 - 1/2 - 1/4
= 10 -1/4
= 9 3/4
__
Strategy: turn the subtracted fraction into a whole number by adding 1/4 to both parts of the problem, then subtract the whole number.
10 1/2 - 3/4 = (10 1/2 +1/4) -(3/4 +1/4)
= 10 3/4 -1
= 9 3/4
_____
We assume that you know that 1/2 + 1/4 = 3/4, or 3/4 -1/2 = 1/4. If you need to, you can get there by using the equivalent: 1/2 = 2/4.
Answer: 
<u>Find Common Denominator</u>
2: 2,4,6,8,10
4: 4,8,12,16,20
CD=4
<u>Add</u>
1/4+2/4=3/4
3/4=.75
Answer:
the answer is 21x+5
Step-by-step explanation:
because there are 2 x and if you multiply 7x and 3x it will be 21 than you put the x, so 21x And then add the +5 so it Will be 21x+5
