-5x + y = -5.....multiply by -2
-4x + 2y = 2
---------------
10x - 2y = 10 (result of multiplying by -2)
-4x + 2y = 2
-----------------add
6x = 12
x = 12/6
x = 2
-5x + y = -5
-5(2) + y = -5
-10 + y = -5
y = -5 + 10
y = 5
solution is (2,5)
Answer:
m∠2=65
Step-by-step explanation:
They are corresponding angels which means they are congruent.
Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4
Answer:
13
Step-by-step explanation:
13 because first you do 6-3 which equals 3 then you do 18 / 3 because of PEMDAS so you get 6 the you add 7 by 6 which equals 13!
Please mark brainliest if this helped.
The word "of" is the same thing as a multiplication sign!
So instead see it this way:
53% × 470
To solve this, you can use the cross product method :
= 
(470 × 63) ÷ 100 = ?
29 610 ÷ 100 = ?
296.1 = ?
53% of 470 is 296.1
There you go! I really hope this helped, if there's anything just let me know! :)
