Jerome added two numbers. The sum was 83. One of the numbers was 45.What was the other number? Work shown please

Answers

Answer 1

Answer: Put one number as x and the other as y
x+y=83
Since we already know one is 45, we substitute one of them for 45.
45+x=83
Subtract 45 on each side
x=38
The other number is 38. Hope this helps.

Solve each quadratic equation by factoring. 6n^2-18n-18=6

Answers

Divide by 6 to get:

n^2-3n-3=1

Subtracting 1, we see that:

n^2-3n-4=0

Factoring, we have:

(n-4)(n+1)=0

Therefore, 4 and -1 are the solutions, since if either n-4 or n+1 is zero, the whole expression is zero.

$6n^(2)-18n-18=6 \n \n 6n^(2)-18n-24=0 \n \n 6(n^(2)-3n-4)=0 \n \n n^(2)-3n-4=0 \n \n n^(2)-4n+n-4=0 \n \n n(n-4)+(n-4)=0 \n \n (n+1)(n-4)=0 \n \n n+1=0 \ \vee \ n-4=0 \n \n n=-1 \ \vee \ n=4 \n \n n\in \lbrace -1,4 \rbrace$

This is an example of the Associative Property of addition.

HJ=53 IK=56 JK=15 find the length of HI and IJ

Answers

HI = (HJ + JK) - IK

HI = (53 + 15) - 56 = 69 - 56 = 13

IJ = HJ - HI = 53 - 13 = 40
