First, you will want to get the denominators of both fractions to be the same, the easiest way to do this is by multiplying the denominators, so 5 x 7 = 35
next you need to do the same for the numerators, so 2 x 7 = 14 and 2 x 5 = 10
now you have the equation 14/35 + 10/35
next, you add the numerators. so, 14 + 10 = 24
therefor, 2/5 + 2/7 =24/35
so your answer is 24/35
Answer:
1.6
Step-by-step explanation:
7 and three tenths = 7 + 3/10 = 7.3
5 and seven tenths = 5 + 7/10 = 5.7
7.3-5.7 = 1.6 or can be written as 1 and six tenths, or 1 and three fifths.
Three equations are:
2x+1=6x+3
8x+6=2x+3
8x+4=2x+1
<u>Step-by-step explanation:</u>
Using the digits 0-9, no more than one time each, place a digit in a box to create an equation with a solution x= -1/2 . We need to Create three equations. Formula is below. __ x+ __=__ x+ __ . Let's find out:
2x+1=6x+3
Let's verify this :
⇒ 
⇒ 
⇒ 
8x+6=2x+3
Let's verify this :
⇒ 
⇒ 
⇒ 
8x+4=2x+1
Let's verify this :
⇒ 
⇒ 
⇒ 
Since x = 3, plus 3 into x and you should get f(3) = 6(3) which is equal to the answer 18.
