3x-25=2x-10 add 25 on both sides
3x=2x+15 then subtract 2x on both sides
<span>X=15 </span>
Plug in x to "3x-25" which would equal 20
<span>M< L = 20 so, 180-20= 160 </span>
<span>M=160

Example -
4x2<span> + 6x + 5</span>
This polynomial has three terms. The first one is 4x2, the second is 6x, and the third is 5
The exponent of the first term is 2
The exponent of the second term is 1 because 6x = 6x1
The exponent of the third term is 0 because 5 = 5x0
What? 5x0<span> = 5?</span>
Well, anything with an exponent of 0 is always equal to 1
So, 5x0<span> = 5 × x</span>0<span> = 5 × 1 = 5</span>
Since the highest exponent is 2, the degree of 4x2<span> + 6x + 5 is 2</span>
Answer:
5:7
Step-by-step explanation:
There are 10 boys and 4 girls taking dance lessons
Therefore, the total number of students taking dance lessons is;
10 + 4 = 14
Now, ratio of boys to the number of students taking dance lessons will be:
Number or boys taking dance lessons : Total number of students taking dance lessons
this will give;
10 : 14
= 10 / 14
dividing the numerator and denominator by 2 to reduce to the lowest term
5 / 7
or 5:7
Answer:
There are three terms.......1/2 and -18y and 9z and -2
Step-by-step explanation:
A term is separated by a - sign or a + sign. In this expression there are 2 (-) signs and 1 ( +) sign. 2+1 = 3 so there are three terms.
