Answer:21
Step-by-step explanation:
90+44+(3n-5)=180
134+(3n-5)=180, subtract 134 from both sides
3n-5=46
3n=51
n=17
To check: 90+44+(3x17-5)=180
Its pretty simple
9x-7y = 22
x + 3y = -24
(9x-7y = 22)
-9(x + 3y = -24)
= -9x -27y = 216
+ 9x-7y = 22
= -34y = 238
= / -34 = 238/-34
y = -7
now plug -7 in one of the equation
x + 3(-7) = -24
x -21 = -24
+21. +21
x = -3
so answer is x = -3 and y = -7
Answer:
0.23
Step-by-step explanation:
A formula I like to use to find the answer to these types of questions is
first, multiply 828×100=82,800
now divide 82800÷3600=23
so your answer is 23%==0.23
