Answer:
He would need 42 cm *or 14cm
Step-by-step explanation:
28/4 is 7
that means that he used 7 cm of tape per present
6 x 7 is 42
that means that he would need 42 cm of tape
4 to 28
6 to 42
*If he already has 4 presents done and he needs to 2 more present then he would need 14 cm, 2 x 7 is 14
First, figure out what you do and don't know....
You do know that 3 times the sum of a number and 4 is 18 more than the number....you don't know the number so you make it the variable x
now take 3 times the sum of a number and 4 and make that an expression 3x+4 this expression is the same or equal to the sum of x and 18 x+18
3x+4=x+18
2x+4=18
2x=14
x=7
hope this helped :)
9 - c = -13

It is A because it can’t be B and it can’t be C and it can’t be D so my answer is A
