1 answer:
Andrei [34K]3 years ago
3 0

Answer:

4. 61

5. approximately 43

6. 120

Step-by-step explanation:

4. 80 + 39 = 119

   180 - 119 = 61

5. 7x - 10 = 90

        +10   +10

        7x = 100

divide by 7

x = 14.3

3 times 14.3 = 42.9

6. 70 + 50 = 120

   180 - 120 = 60

   180 - 60 = 120

Simplify the expression by combining like terms: x + 7x
Aneli [31]

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.
