Answer:
x = 9
Step-by-step explanation:
(3x - 21) = (2x - 13) eliminate by subtracting 2x and add 21 on both sides
x = 9
Answer:
.58 x 200=116
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
-3x ≤ -5
if we divide for a negative number we have to change the sign of the inequality
x ≥ 5/3
5/3 = 1,666
so the nearest integer number is 2
Answer:
angle fde = 37 degree
Step-by-step explanation:
we have,
angle bdc = angle fde
for angle bdc
adf = 90, adb = 53
let the value be x
=> 90+53+x = 180
=> 143+x = 180
=> x = 180 - 143
=> x = 37
bdc = 37
so, fde = 37
Answer:
(5,1) is not a solution of the above system of equations.
Step-by-step explanation:
We are given a system of equations that are
- 5y = - 5 ......... (1) and
7x + 6y = 7 ........... (2)
So, solving equation (1) we get y = 1 and putting y = 1 in the equation (2) we get 7x = 7 - 6(1) = 1
⇒ 
So, it clear from the solution of the above equations i.e. (
), we can say that (5,1) is not a solution of the above system of equations. (Answer)
