a = 4
Step-by-step explanation:
Create equivalent expressions in the equation that all have equal bases.72(3x)=73(2x+1)72(3x)=73(2x+1)Since the bases are the same, then two expressions are only equal if the exponents are also equal.2(3x)=3(2x+1)
Answer:
60cm²
Step-by-step explanation:
as the green and blue box are squares they will have the same sides, length.
so all the sides in the green and blue squares are 3
the pink and orange rectangles : the longer is 7 the shorter one is 3
for the top length of the whole shape is = 7 +3 = 10
side length of the shape is 3 + 3= 6
so then you do 6 x 10 = 60
60 cm² is the answer :)

Answer:
5.5 yards.
Step-by-step explanation:
We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.
First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:


We know that 1 yard equal to 36 inches. To convert 198 inches into yards, we will divide 198 by 36 as:



Therefore, the total amount of ribbon that Mimi needs is 5.5 yards.
