Use the expression to solve for the number.
2n + 4 = 22
2n = 22 - 4
2n = 18
n = 18/2
n = 9
The number is 9.
Hope this helps :)
Answer:
Unit rates are useful because they allow you to make direct comparisons. For example, you have your choice between two bottles of ketchup.
Step-by-step explanation:
The number of quarts of berries Charlie picked is C
the number of quarts of berries Noel picked is N
since they picked a total of 92 quarts, C+N=92
Since Charlie picked 6 more quarts than Noel, C-N=6
add the 2 equations
C+N+C-N=2C=98
C=49
N=92-49=43
Noel picked 43 quarts.
Answer:
A=47 Degrees
Step-by-step explanation:
all triangles add up to 180 degrees
exterior angles add up to 180
360-100+127
360-227
133=B
180-133=47
A=47 Degrees
Whenever a number is beside a parenthesis without a sign it means multiplication. So you would use PEMDAS work in parenthesis then exponents, multiplication (from left to right) addition and subtraction (from left to right). so you would add 20+3 and get 23 then multiply that by -5 to get -115 as your answer.
