Answer:
answer is 4.
Step-by-step explanation:
the difference between 5 and 9 is 4
9-5=4
and in 13 and 17 it's the same
17-13=4
so the common difference is 4
write 4️⃣is the answer
x = 24
x - (3 · 4) = 12
x - 12 = 12
+ 12 + 12
There are 13 numbers here:
30, 30, 31, 32, 42, 49, 58, 58, 67, 67, 69, 78, 90.
The median number is the 7th number, which is 58.
nr. 1 and 3 is a Dilation 2 and 4 are not Dilations
Dilation is an elnargment or shink of a figure by a x(factor) that makes the SAME image but smaller or larger
80 x 4 = 79+81+77+x
320=237 + x
320-237 = x
83=x
so Marianne must score 83 points or higher on her last test
