Answer:
Answer is 57.
Step-by-step explanation:
All angles on a line add up to 180.
180 - 123 = 57
Answer:
1000
Step-by-step explanation:
1. Add all of his previous stubs together
= 1000 + 1181 + 1191 + 1200 + 1268 + 1328 + 2584
= 9752
2. Divide by number of pay stubs to find the average
9752/7 = 1393.14
3. We must find a number that is the average. I decided to round 9752 to 1000 and we will add that into the equation and divided by 8
1000 + 1181 + 1191 + 1200 + 1268 + 1328 + 2584 + 1000
= 10752/8
= 1344
4. Know we know if he gets 1000$ on his next paycheck he will get an average of $1344
Hope this helped :)
5 5/6 + 5 4/5 =
5 + 5 = 10
5/6 + 4/5 = 25/30 + 24/30 = 49/30 = 1 19/30
10 + 1 19/30 = 11 19/30 <==
you must factorize it as a difference of squares
a^2-b^2 = (a-b)(a+b),
9b^2-25 = (3b)^{2-(5)^2= (3b-5)(3b+5)
Answer:
a = 10 or a = -10
Step-by-step explanation:
a^-2 = 1/100
We know 100 = 10^2
a^-2 = 1/10^2
We know 1/b^c = b^-c
1/a^2 = 1/ 10^2
Multiply by a^2 on each side
a^2 *1/a^2 = 1/ 10^2 *a^2
1 = a^2/10^2
Multiply by 10^2 on each side
1 0^2= a^2/10^2 * 10^2
10^2 = a^2
Take the square root of each side
sqrt(10^2) = sqrt(a^2)
±10 =a
