2. Solve. All changes The sum of two numbers is 70 and their difference is 30. Find the two numbers using the process of substitution. Letr = the first number and y= the second number. Write an equation showing the sum of the numbers: a Write an equation showing the difference of the numbers: d a. I ty=I - y b. 70.x - 30y = 40 C. 70x + 30y = 100 d. I-y=30 e. I+y= 70 3 Salve PREVIOUS 1-10 of 10 ENEO REVIE

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
