Answer:
30
Step-by-step explanation:
2/3 = x/18
2*18 = 3x
36 = 3x
x=12
so there are 12 boys
12+18=30
To begin, Arnold should sort on whether or not it is a screw, nut, bolt.
This might only be # 1 and 3 but you should be able to put together a number line with the information I provided. Some of the #s may look different but that is because I used the Least Common Denominator. Hope this helps!
Screws: Least to greatest (top = least)
4 Screws 4/64” x 3” long
12 Screws 5/64” x 3” long
3 Screws 6/64” x 4” long
6 Screws 11/64” x 4” long
16 Screws 24/64” x 2” long
1 Screw 28/64” x 3” long
1 Screw 32/64” x 3” long
1 Screw 48/64” x 2” long
Hex Bolts: Least to greatest by diameter (top = least)
4 Hex bolts 1.5” x 4” long
4 Hex bolts 1.875” x 4” long
1 Hex bolt 2.25” x 2” long
6 Hex bolts 3.375” x 3” long
4 Hex bolts 3.75” x 3” long
You can first convert the mixed numbers into fractions and then operate them
if for example you have 3 4/3
to convert it you first multiply the whole by the denominator and then you add the nominator. The denominator is the same.
so 3 4/3=13/3
In this question, you're solving for x.
Solve for x:
x + 4.2 = 7
You need to get x by itself, to do so, you would need to subtract 4.2 from both sides:
x = 2.8
Answer:
x = 2.8
