Answer:
Where's the question or picture?
Step-by-step explanation:
In order to solve for x in the equation <span>7x + 15 = 38, you must first subtract 15 from both sides.
</span><span>7x + 15 = 38
</span><span>7x + 15 - 15 = 38 - 15
7x = 23
Then you must divide so there is only 1x = a number. This can be done by dividing both sides by 7.
7x = 23
7x / 7 = 23 / 7
x ≈ </span>3.286
So the solution for x in the equation 7x + 15 = 38 is x ≈ 3.286.
Hope this helps!
Answer:
56 cards
Step-by-step explanation:
If 5 baseball cards multiplied by 8 is 40, then you multiply the 7 football cards by 8 as well.
7x8=56
Evaluate the given function in x=-4.
This is, replace the x in the function for -4 and find the value of g(-4).

The value of g(-4) is 32.
So multiplying two rationals is the same as multiplying two such as fraction as when you multiplying two rational numbers produces another rational number.
