The two numbers are -6 and 7
<em><u>Solution:</u></em>
Given that eight times a number plus five times another number is -13
The sum of two numbers is 1
To find: the two numbers
Let the two numbers be "a" and "b"
From given information,
Eight times a number plus five times another number = -13
eight times a number "a" + five times another number "b" = -13
8a + 5b = -13 ---- eqn 1
Also given that sum of two numbers is 1
sum of two numbers = 1
a + b = 1 ---- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to find values of "a" and "b"</u></em>
From eqn 2,
a = 1 - b ----- eqn 3
Substitute eqn 3 in eqn 1
8(1 - b) + 5b = -13
8 - 8b + 5b = -13
8 - 3b = -13
-3b = -13 - 8
-3b = -21
<h3>b = 7</h3>
Substitute b = 7 in eqn 3
a = 1 - 7
<h3>a = -6</h3>
Thus the two numbers are -6 and 7
Answer:
720
Step-by-step explanation:
Total-107
Male teacher-n
Female teacher-n+23
N+n+23=107
2n+23=107
2n= 84
N=42
Male teacher-42
Female teacher-42+23=65
65/107 teacher are female
Answer:
K = 6
Step-by-step explanation:
Plug in what the letter equals to
Equation will look like:
2(11) = 4 + 3k or 3k + 4 = 2(11)
multiple the 2 by 11 and get 22
3k + 4 = 22 subtract the 4 so it can leave the 3k alone
22 - 4 = 18 now divide 3 from k and do it in the other side
18/3 = 6
so K = 6
