Answer: A
Explanation: using the common ratio we can solve this. 24:8 = x:4
24 divided by 8 is 3.
Therefore x divided by 4 should be 3 too.
4 multiplied by 3 is 12, so x = 12.
For y:
When triangles are similar, the angles are always the same. So y is simply 40 degrees.
Answer:
She has 15 more purple rocks than blue.
Step-by-step explanation:
purple= 2/3 of all rocks
blue= 3/4 of all rocks that aren't purple
silver= 3 (or 1/4 of all rocks that aren't purple)
if 3 (silver) is 1/4 of all rocks that aren't purple, blue (3/4) is 3x3=9
if purple is 2/3 of all rocks, blue and silver are 1/3 of all rocks
so 1/3 of all rocks would be 9+3=12
if 1/3=12, then 2/3 (purple)=24
-----
At this point:
purple=24
blue=9
silver=3
-----
purple (24) - blue (9) =15
She has 15 more purple rocks than she does blue.
Answer:-5
Step-by-step explanation:
2x+3=-7
2x=-7-3
x=-10/2
so,
x=-5
Trey will read 18 pages in 45 minutes.
