help me por favor

Answers

Answer: (3+6)x5

Step-by-step explanation: It wants you to add first so put parentheses around 3+6 and then multiply by 5.

The expression for the sequence of operations would be; (3 + 6 ) x 5.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol.

Given that the phrase "add 3 to 6, then multiply the result by 5"

Then first add 3 and 6 = 3 + 6

To indicate the multiplication sign we will use x.

Now multiply the result by 5;

(3 + 6 ) x 5

Hence, the expression for the sequence of operations would be; (3 + 6 ) x 5.

What are the similar triangles?

Similar triangles have the same corresponding angle measures and proportional side lengths.

Given that, two triangles are similar, Δ MNO ~ Δ PQR,

According to definition of similar triangles,

PR/MO = QP/NM

x/4 = 2/5

x = 8/5

x = [tex]1\frac{3}{5}[/tex]

Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices

Rosemary needs to maintain 126 mph.

Rosemary needs to maintain 65 mph.

Rosemary needs to maintain 56 mph.

Answers

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

Answer:

56

Step-by-step explanation:

84 / 1.5 = 56

Among his courtiers was a young man of that fineness of blood and lowness of station common to the conventional heroes of romance who love royal maidens.
