Answer:
3(n+5)=-30
Step-by-step explanation:
Three times the sum of a number and 5 is - 30
Vocabulary:
times = multiplication, represented with *
sum = addition, represented by +
unknown number = n
Three * the sum of a number and 5
The sum of a number and 5 is the same as saying n + 5
So we are multiplying 3 by n + 5
Because n is an unknown variable we have to separate the sum of n and 5 from being multiplied by 3 with parenthesis. We do this because if we want to multiply 3 by the sum of n and 5. If we put 3 * n + 5 we are only multiplying the unknown variable by 3 not including the 5 that is added to it.
So we get 3( n + 5 ) is -30
3(n+5)=-30 is the answer.
- the number of green blocks which is equal to the number of favourable events
- the number of all blocks, which is equal to the number of all possible outcomes
B- Not sure if it's a line
C- y=(-x/2)-6
D- y=4x-12
E- y=(2/5)x-10
Just divide 7 by 6 to convert the fraction to decimal form and then compare the two
