She began with 20.

SOLVE FOR X. pls i need help
Lyrx [107]
X=8
Set up proportions would give you: 10/3x+1 = 22/7x-1
With that in mind, cross multiply, which would give you: 10(7x-1) = 22(3x+1).
Turns into: 70x -10 = 66x+22. Then just solve for x

Two lions, Fluffy and Fireball, met at the zoo. Fluffy's tail is 1\dfrac{1}{3}1 3 1 ​ 1, start fraction, 1, divided by, 3, end f
maks197457 [2]

Answer: Fluffy's tail  is \dfrac1{12} m longer than Fireball's tail.

Step-by-step explanation:

Length of Fluffy's tail = 1\dfrac13 m =\dfrac43 m

Length of Fireball's tail = 1\dfrac14 m =\dfrac54 m

Difference = Length of Fluffy's tail - Length of Fireball's tail

=\dfrac43-\dfrac54=\dfrac{4\times4-5\times3}{3\times4}\\\\=\dfrac{16-15}{12}\\\\=\dfrac1{12}

Hence, Fluffy's tail  is \dfrac1{12} m longer than Fireball's tail.

Fill in the blanks<br>864+2006=--------+864<br><br>5351 +(574+799)= 574+(5351+_____)​
Mama L [17]

Answer:

2006

799

Step-by-step explanation:

Given the expression:

The right hand side of the sun must be equal to the left hand side ;

Therefore ;

864+2006=--------+864

The sum of 864 and 2006 must be equal to the right hand side sum ; hence

864+2006= 2006 +864

Similarly, the left hand side and right havd side must also be equal here ;

5351 + 574 + 799 = 574 + 5351 + 799

Hence, the missing value is 799
