Answer:
x=5
Step-by-step explanation:
Alright you will need to use PEMDAS for this
- Parenthesis
- Exponent
- Multiplication
- Division
- Addition
- Subtraction ( Take note of this )
Step 1
9(3x – 16) + 15 = 6x – 24 You will remove parenthesis here
27x-129=6x-24
Step 2
Then subtract 6x,
27x-129=6x-24
21x-129=-24
Step 3
Then you add 129 to the sides,
21x-129=-24
21x=105
After that, you divide the sides by 21 so that you can get your answer
5
So therefore, your answer will be x=5
H(arold) = 2 + 2*K(enneth)
H = 2 + 2K
H + K = 38
Substitution:
2 + 2K + K = 38
3K = 36
K = 12
Kenneth solved 12 problems and Harold solved (2(12) + 2 = 24 + 2 =) 26 problems
Answer:for the first one: 154.5852
Step-by-step explanation:
720 devided by 4 is 180
180 devided by 7 is 25.7142
so 25.7142x6=154.2852
so depending on what year your in, write the remainder or dont :)
~
120 devided by 5 is 24
thats all I know I tried w question 2 but it hurts mah brain, especially cuz I have *mental disorder* so its hard to focus aha- sorry
