Answer:
72
Step-by-step explanation:
for the rectangles you use the formula :
a=lw 3x6=18x2=36 + 4x6=24
and for the triangles you use:
a=1/2bh 3x4=12/2 + 3x4=12/2
then you add it all together
36+24+12=72
<span>8.3 ounces + 7.75 ounces = 16.05 ounces</span>
In order to solve equations like these, you need to move all terms involving the variable on one side, and all the numeric constants on the other side.
To do so, we can add/subtract the same quantity to both sides.
For example, we can add 5.2 to both sides to get
Then, we can add all the terms on the left hand side, and we have
Finally, we can divide both sides by -3.14:
In order to check the solution, we have to plug the value we found for x in the initial equation:
which is clearly true.
To find the value of 1 out of all pieces divided, add the ratios.
8+1= 9
Now divide 72 by the total number.
72/9 = 8 (the value of one 1 unit)
Now to find the value of 8 units= 8*8 = 64
Value of 1 unit= 8
Answer:
Word problem 3
Step-by-step explanation:
Word Problem one is a subtraction problem since Felicia is giving away two marbles to Lucas. Word Problem two is a division problem since Felicia is evenly dividing the number of marbles she has into two bags. Word Problem three is a multiplication problem because Ryan has two times as many marbles that Felicia does. Word Problem four is an addition problem because she found two more marbles while she already has eight marbles. Keywords for subtraction word problems are: fewer than, decrease, take away, less than, minus, difference, change, lost reduced, and subtract. Keywords for division word problems are: As much, cut up, groups, equally, sharing, half, how many in each, parts, per percent, quotient, ratio, and separated. Keywords for multiplication word problems are: double, every, factor, increased, multiplied product, times, and tripled.
