Answer:
x = -1
Step-by-step explanation:
5x + 3y = 26
- (6x + 7y = 21)
_________
-x - 4x = 5
-5x = 5
x = -1
She put the decimal point in the wrong soy
Answer:In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).
Step-by-step explanation:
Answer:
61.9
Step-by-step explanation:
Look at the number next to the tenths place which in this case is 5.
When a number is greater than or equal to 5 you round up.
So 61.85 becomes 61.9
X=8, we know all the inside angles have to equal 180 then solve for x. JKL= 60, KLJ=24, LJK=96. So 60+24+96=180
