Let x = the number.
"increased by" tells you we are adding.
"twice a number" tells you 2 times a number.
16 + 2x = - 24
Subtract 16 from both sides so that we have the variable on one sides and the constants on the other.
2x = - 24 - 16
2x = - 40
Divide by 2 to isolate the variable.
x = - 40/2 = - 20
Your solution is - 20.
To check your answer, plug in.
16 + 2(-20) = - 24
16 - 40 = - 24
- 24 = - 24
Step-by-step explanation:
If f = price of filing cabinet and c = price of cupboard we can make up the equation
2f + 4c = 800
we also know that f = 3c, so can substitute that into equation
2 (3c) + 4c = 800
6c + 4c = 800
10c = 800
c = 80
f = 240
Not to be mean Fernanda but it wouldn't be 0 it actually would be 0.19444444 so I would just put 0.194 and put a line over the 4 to show that it repeats continuously
Answer:
C 73
Bcs straight line is 180ns9 the angle should be 34.
So you equate 34=-39+x and u get x as 73
