The equation is two different types and a number and in the question you have to multiple
Answer: -19x
Step-by-step explanation: In this problem, we're asked to simplify the expression.
The two parts of this expression, -8x and 11x are called terms. The numbers in front of the variables are called coefficients.
Because the variables, x and x are identical, the terms get a special name and they're called like terms.
To subtract like terms, we simply subtract their coefficients and add the variable on to the difference of the two numbers.
Since -8 (-11) is -19, -8x - 11x simplifies to -19x.
Answer:
one solution
Step-by-step explanation:
4x + 13 = 3x + 15
subtract 3x from both sides:
x + 13 = 15
subtract 13 from both sides:
x = 2

<u>Answer:</u>
There is only 1 peak in this distribution.
<u>Step-by-step explanation:</u>
In the distribution of exam scores (graded from 0 100) for 86 students 38 students got an A, 28 students got a B, and 20 students got a C.
a) Since, 38 > 28 > 20 , there is only 1 peak for this distribution.
