Marianna [84]2 years ago
5 0

Answer:

a) 75

b) 360 students

c) 56 ; 57 ; 58

d) 134 inches

e) 27°

Step-by-step explanation:

a)

5x = 375 \\ x =  \frac{375}{5} \\ x = 75

b)

\frac{x}{3}  = 120 \\  x = 120 \times 3 \\ x = 360

c)

x + x + 1 + x + 2 = 171 \\ 3x = 168 \\ x = 56 \\ (x + 1 = 57) \\ (x + 2 = 58)

d)

2x + 2 \times 70 = 408 \\ 2x = 408 - 140 \\ x =  \frac{268}{2}  \\ x = 134

e)

180 = 90 + 63 + x \\ x = 180 - 90 - 63 \\ x = 27

fredy the frog was 18 feet down below ground in a well and is trying to climb out the first day he climbed up 7 feet but slid ba
lisov135 [29]

Writing this situation out in terms of operating with integers and indicating Fredy's position at the moment is as follows:

Fredy's position in the well = <u>13 feet in depth</u> or 5 feet from the bottom.

<h3>What is an integer?</h3>

An integer is a whole number, both positive and negative.

<h3>Data and Calculations:</h3>

Depth of well = 18 feet

Height climbed the first day = 7 feet

Height climbed the second day = 4 feet

Height of climb up the well = 11 feet

Depth of slid on the first day = 2 feet

Depth of slid on the second day = 4 feet

Total slid down the well = 6 feet (2 + 4)

The position of Fredy the Frog is at 13 feet (18 - 11 + 6) depth

Thus, based on integer operations, we can conclude that Fredy the Frog has only climbed <u>5 feet</u> (18 - 13) from the well's depth.

<h3>Question Completion:</h3>

Fredy the frog was 18 feet down below ground in a well and is trying to climb out. The first day he climbed up 7 feet but slid back down <u>2 feet</u> the next day he climbed 3 feet but slid back down 4 feet.

combine like terms by subtracting 5.2z from both sides

1.5z = 12.3

divide by 1.5

Passes through (2,4). same y-intercept as line with equation x-4y=8
mamaluj [8]

Answer:

2x + 4y =8

substitute 0 for x

2 (0) + 4y = 8

0 +4y = 8

subtract 0 from both sides

-0 +4y =8 - 0

4y = 8

Divide both sides by 4

Y = 2
