Write the equations: 2.9s+4.7h=6076
 \\ h= 4s
Substitute for h: 2.9s+4.7(4s)=6076
Solve for s:2.9s+4.7(4s)=6076 \\ 2.9s+18.8s=6076 \\ 21.7s=6076 \\ s=280
There were 280 downloads of the standard version. There were 1120 downloads of the high-quality version.

Students are making ornaments and each takes 1/4 of a piece of Bristol board. They go to the cupboard and find 2 1/2 pieces of B
coldgirl [10]

Answer: 10 ornaments

Step-by-step explanation:

From the question, we are informed that students are making ornaments and each takes 1/4 of a piece of Bristol board. We are further told that they go to the cupboard and find 2 1/2 pieces of Bristol board.

The number of ornaments that they make will be gotten by dividing 2 1/2 by 1/4. This will be:

= 2 1/2 ÷ 1/4

= 5/2 ÷ 1/4

= 5/2 × 4/1

= 10

They can make 10 ornaments
