Answers + Step-by-step explanation :
a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign
b) we can solve our equation to find for n, the number jim thought of
7(n + 5) = 91
I will use the distributive property.
7n + 35 = 91
Subtract 35 on both sides
7n = 56
Now divide 7 on both sides to find n
n = 8
The number Jim was thinking of was 8! this should be correct, hope this helps!
Answer:
1
Step-by-step explanation:
If you draw a rectangle divided up into eight even parts, and label them each as 1/8, then you can show your work for how you double it. You do this by "coloring" one in, and then doing the same for a second piece (but color that one in a different way). You can visually double an eighth in that way.
Or, you can simply multiply by 2 to double 1/8:
1/8x2/1=2/8
Answer:
Length of NM is 36 cm
Step-by-step explanation:
Length of MN + Length of NO = Length of MNO (Or only MO)
cm
Thus, length of MN is equal to length of NO i.e 36 cm
The line MNO has point N, that bisect it into two equal half.
Thus, the line MNO has two parts
Total length of line MNO = MN + NO = 
cm
