The coefficient of the term 13a is 13
The coefficient of 6b in expression is a + 6b is 6
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
13a + 6b
We have to find the coefficient of 13a
The coefficients are the numbers that multiply the variables or letters
Here in 13a , a is the variable that is multiplied with number 13
Thus the coefficient of the term 13a is 13
<em><u>Second expression:</u></em>
a + 6b
Here, in 6b , b is the variable that is multiplied with number 6
so 6 is the coefficient
Answer:
Step-by-step explanation:
a+b=9500 equation 1
35a+55b=432500 equation 2
a=9500-b modified equation 1 to isolate a
35(9500-b)+55b=432500 substitute value of a in equ 1 into value of a equ 2
332500-35b+55b=432500
20b=100000
b=5000
solve for a
a + b=9500
a + 5000=9500
a=4500
check answer:
35a+55b=432500
35(4500)+55(5000)=432500
157500+275000=432500
432500=432500
