Answer:
34
Step-by-step explanation:
We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.
180=(x+12)+100+x
We can remove the parentheses and combine x plus x to 2x.
180=100+2x+12
100+12=112
so
180=112+2x
-112 -112
68=2x
÷2 ÷2
34=x
C>12
Y=-3 -3+13= 10
7x-14 Multiply
112
Answer:
If a son were to have a grandchild, Bob and Fran would then have two great-grandchildren.
Step-by-step explanation:
C = children
G = grand children
GG = great grand children
Bob and Fran have 3 children, 2 sons(C) and 1 daughter(C).
Their 2 sons have 5 children(G) between them. One son has 2 children(G). Their daughter has 3 children(G) and 1 grandchild(GG).
If the son with 2 children had a grandchild(GG).
Now we can see that, at present we have a single great grand child that is of their daughter's.
As given, if a son were to have a grandchild, Bob and Fran would then have two great-grandchildren.
