What is the first step in evaluating the expression shown below? (12.9 – 3.1) × 6.2 – 2 + 43 A. Multiply 3.1 and 6.2. B. Add 2 and 43. C. Subtract 3.1 from 12.9. D. Subtract 2 from 6.2.

Answers

Answer 1

Answer: Subtract 3.1 from 12.9

Step-by-step explanation:

The first step in evaluating the expression (12.9 – 3.1) × 6.2 – 2 + 43 is to open the bracket first and then subtract 3.1 from 12.9 which will give 9.8.

This follows the rule of BODMAS which says that B which stands for Bracket must be opened and solved first in a given expression.

Answers

Answer:

Zero

Step-by-step explanation:

Find the slope using rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(4 - 4) / (4 - 0)

0 / 4

= 0

So, the slope is zero.

George is getting balloons for his father's birthday party. He wants each balloon string to be 6 feet long. At the party store, string is sold by the yard. If George wants to get 82 balloons, how many yards of string will he need?

Answers

Answer:

164 yards

Step-by-step explanation:

Each balloon string = 6 feet

Total balloons needed for the birthday = 82

how many yards of string will he need?

Total strings of balloon needed = Each balloon string × Total balloons needed for the birthday

= 6 feet × 82

= 492 feet

Total strings of balloon needed = 492 feet

1 yard : 3 feet

x yards : 492 feet

1 : 3 = x : 492

1/3 = x / 492

1 * 492 = 3 * x

492 = 3x

x = 492/3

= 164

x = 164 yards

492 feet = 164 yards

Answer:

Step-by-step explanation:

The midsegment of a trapezoid is equal to the sum of the two bases divided by two. This means that 17 = (2x + 1 + 3x + 8)/2. To start, multiply both sides by 2 to get 34 = 2x + 1 + 3x + 8. Next, combine like terms to get 34 = 5x + 9. Subtract 9 from both sides for 25 = 5x. Finally, divide both sides by 5 to get an x-value of 5.
