7x+5=2x-35 <br> What is the answer
Mnenie [13.5K]
7x + 5 = 2x - 35


=> 7x - 2x = - 35 - 5


=> x( 7 - 2 ) = - ( 35 + 5 )


=> x( 5 ) = - ( 40 )


=> x × 5 = - 40


= >x = \frac{ - \cancel{40} \: \: \: ^{8} }{ \cancel{5}} \\ \\ \\ = > x = 5

x = 5



Therefore the value of x in the given equation 5

Which statement and reasoning is true for finding the common denominator for the fraction 1/4 and 1/8?
Ne4ueva [31]

Answer:

A I can use 8 because 4*2 =8

C I can use 16 because 4*4 = 16 and 2*16 = 16

D I can use 24 because 6*4 =24 and 3*8 =24

Step-by-step explanation:

1/4  and 1/8

The multiples of 4

4,8,12,16,20,24

The multiples of 8

8,16,24,32

The first multiple that 4 and 8 have in common is 8  so that is the least common denominator

But 16 and 24  are also multiples  so they are also common denominators of 4 and 8.  ( They are not the least common multiple)
