Answer:
about 23 minutes
Step-by-step explanation:
(65x35)/(65+35)= 2,275/100= 22.75 minutes (or 23 if rounded)
Answer:
Jose is 54years Rachael is 38years
Step-by-step explanation:
Jose=x-12
Rachael=x-12/2
sum of their ages x-12+x-12/2=63
collect like terms
x=54years
Jose =54years
Rachael=38years
Answer:
3.75 or 15/4
Step-by-step explanation:
8x+5=35
Subtract 5 from the left side to cancel it out, do the same thing to 35.
8x=30
Divide 8x by 8 to get x alone, do the same thing to 30.
x=3.75, or once you simplify 30/8, you get 15/4.
Answer: 14
Step-by-step explanation:
We want the smallest value so:
we know 5n is the square of a number, so
n = 5a^2, so a > 1
we know 75np is the cube of a number, so
p= 3^2a = 9a
Now, n+p = 5a^2 + 9a = a [5a+9]
The smallest value would be when a=1
Therefore when you plug it in , n+p = 5+9 = 14
Hopefully that helped :)
Answer: Similar with coordinates A’ (8, -12), B’ (4, -16) and C’ (-20, 8)
Step-by-step explanation:
Since the size of the triangle changes they cannot be congruent.
Assuming the centre of dilation (enlargement) is (0, 0) then just double the coordinates of each point
