Answer:
a) 5y²
Step-by-step explanation:
5 divided by 1 is still 5
y^5/y^3 subtract the exponents since the base is the same
Answer:
40
Step-by-step explanation:
1. Change 48 cm to mm, which will give you 480 mm
2. Divide 480 mm by 12 mm, that will give you 40
Therefore, Victor needs 40 books to make his desired height.
-10x-10 = -3x+4
+3x +3x
————————
-7x-10 = 4
+10 +10
————————
-7x = 14
then divide -7 on both side of the equal sign
you’ll get x=-2
then plug in -2 as x into one of the equations ( it doesn’t matter which one)
y= -10(-2)-10 = 20-10= 10
so y=10
The side length is the square root of 8. Because the square has 4 equal sides, the side lengths must be equal. So the answer is approximately 2.83.
Answer:
55 pirates for 5 ships, 121 pirates for 11 ships
Step-by-step explanation:
for every 2 ships he needs 22 pirates, divide both by 2 and we see that for every ship he needs 11 pirates, also can write as 2x= 22 and divide both sides by 2, x=11 now that we know for every ship he needs 11 pirates we just multiply 11 times the amount of ships or 11x=y, 11 times 5 is 55 and 11 times 11 is 121
