If the machine makes 5 buttons at a time,and each doll gets 5 buttons then one doll is the answer
Answer:
b=1/12 or just 12
Step-by-step explanation:
combine like terms
1/3b +12=16
subtract 12 on both sides
1/3b=4
divided both sides with 1/3
b= 12 or 1/12
hope this helps.. :/
Answer:
![\boxed{ \ - \frac{3}{45} }](https://tex.z-dn.net/?f=%20%20%5Cboxed%7B%20%5C%20-%20%20%5Cfrac%7B3%7D%7B45%7D%20%7D)
Step-by-step explanation:
10 3/9 - 10 2/5
we need to convert mixed fractions to improper fractions
![10 \frac{3}{9} = \frac{10 \times 9 + 3}{9} = \frac{93}{9}](https://tex.z-dn.net/?f=10%20%5Cfrac%7B3%7D%7B9%7D%20%20%3D%20%20%5Cfrac%7B10%20%5Ctimes%209%20%2B%203%7D%7B9%7D%20%20%3D%20%20%5Cfrac%7B93%7D%7B9%7D%20)
![10 \frac{2}{5} = \frac{10 \times 5 + 2}{5} = \frac{52}{5}](https://tex.z-dn.net/?f=10%20%5Cfrac%7B2%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B10%20%5Ctimes%205%20%2B%202%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B52%7D%7B5%7D%20)
Now, we have 93/9 - 52/5
We need to equate the denominators, before subtracting them.
![\frac{93}{9} - \frac{52}{5} = \frac{93 \times 5}{45} - \frac{52 \times 9}{45}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B93%7D%7B9%7D%20%20-%20%20%5Cfrac%7B52%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B93%20%5Ctimes%205%7D%7B45%7D%20%20-%20%20%5Cfrac%7B52%20%5Ctimes%209%7D%7B45%7D%20)
![\frac{465}{45} - \frac{468}{45}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B465%7D%7B45%7D%20%20-%20%20%5Cfrac%7B468%7D%7B45%7D%20)
![\frac{ - 3}{45}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B%20-%203%7D%7B45%7D%20)

The result of 10 3/9- 10 2/5 is - 3/45
Answer:
√30
Step-by-step explanation:
We can find the value of x by using Euclidean theorem
x^2 = 3 × 10
if x^ = 30 then x = √30
Answer:
C. x=3 and y=−6
Step-by-step explanation:
Step: Solvex−2y=15for x:
x−2y=15
x−2y+2y=15+2y(Add 2y to both sides)
x=2y+15
Step: Substitute2y+15forxin2x+4y=−18:
2x+4y=−18
2(2y+15)+4y=−18
8y+30=−18(Simplify both sides of the equation)
8y+30+−30=−18+−30(Add -30 to both sides)
8y=−48
8y8=−488(Divide both sides by 8)
y=−6
Step: Substitute−6foryinx=2y+15:
x=2y+15
x=(2)(−6)+15
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=−6
