Product of 5 and y added to 3

Answers

Answer:

5y + 3

Step-by-step explanation:

Product of 5 and y means multiplication pf 5 and y

Thus, Product of 5 and y = 5 × y = 5y

Now, 5y is added to 3 means Sum of both 5y and 3

Thus, 5y is added to 3 = 5y + 3

Hence, Product of 5 and y added to 3 = 5y + 3

product = multiplication
5 × y or 5y 
added to 3
so the answer is 5y + 3

-16 = 0.2b please show work

Answers

-16 = 0.2b

Divide 0.2 on both sides to isolate b.

-16 ÷ 0.2 = -80

-80 = b

b = -80. 
divide 0.2 to -16 and then you have your but to check if its right multiply 0.2 to the number you get.and the answer that you get is a negative

When can you add or subtract equations in a system to solve the system? when do you have to multiply first? Justify your answers with examples.

Erin received the following scores on her last four spelling tests.21\25, 82%, 0. 8, 17\20.Which of these is Erin’s highest score?

Answers

Answer:

The highest score is the last one 17/20

Step-by-step explanation:

Step 1:  Convert all to percentage

21/25 -> 0.84 * 100 -> 84%

82%

0.8 * 100 -> 80%

17/20 -> 0.85 * 100 -> 85%

Answer:  The highest score is the last one 17/20

\huge\boxed{(17)/(20)}

We will convert each of the scores to a percentage.

(21)/(25)*(4)/(4)\to(21*4)/(25*4)\to(84)/(100)\to84\%

82\%

0.8*100\to80\%

\boxed{(17)/(20)}*(5)/(5)\to(85)/(100)\to\boxed{85\%}

So, the answer is the last option.
