9 × n - 20 = 16
9n - 20 = 16
+ 20
9n = 36
÷ 9
n = 4
Hope this helps! :)
Answer:
See below.
Step-by-step explanation:
Rectangle PQRS is the shape in neon green. The area is b*h with base 7 and height 2. The area is 14.
Square ABCD is the shape in black. The area is s^2 with side 4. The area is 16.
Triangle EFG is the shape in purple. The area is 1/2 b*h with base 8 and height 4. The area is 1/2 *8*4 = 16.
Triangle UVW is the shape in pink. The area is 1/2 b*h with base 7 and height 4. The area is 1/2 * 7*4 = 14.
Well, you're asking for a refresher on multiplying fractions, but then the
example at the end of your question uses the symbol for division, not
multiplication. So I'll just give you the rules for both operations, and let you
choose the one you need.
To multiply fractions:
-- Multiply the two numerators.
Write the product on top of a new fraction.
-- Multiply the two denominators.
Write the product on the bottom of the new fraction.
-- The new fraction is the product of the two original fractions.
To divide fractions:
-- Invert (flip) the second fraction.
-- Then multiply them.
-- Their product is actually the quotient of the two original fractions.
