Write and solve a real-world problem that can be modeled by the equation 0.75x − 18.50 = 0.65x.

Answer:

2.6m/s

Step-by-step explanation:

[tex]s = d \div t \\ \: = 500 \div192 \\ = 2.6ms \\ [/tex]

Answer:

9.375 km/h

Step-by-step explanation:

192 - 3 minutes 12 seconds

500m - 0,5 kilometers

60 x 60 = 3600

3600:192=18.75

500 x 18.75 = 9375

9375 meters - 9.375 kilometers

Answer:

[tex]f \ge 45[/tex]

[tex]t \ge 45[/tex]

Step-by-step explanation:

Solving (a): No less than 45

In inequalities, no less than means [tex]\ge[/tex]

So, the statement can be represented as:

[tex]f \ge 45[/tex]

Solving (b): At least 45

In inequalities, at least means [tex]\ge[/tex]

So, the statement can be represented as:

[tex]t \ge 45[/tex]

The equation of a line is y = 50x. Then the slope of the line is 50 meters per minute.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Jenna can swim 150 meters in 3 minutes.

If you graph this with minutes on the X-axis and meters on the Y-axis.

Then the slope of the line will be

m = 150 / 3

m = 50 mters per minute

Then the equation will be

y = 50x

Answer:

8 and 64

Step-by-step explanation:

4/1 = 4

8/2 = 4

32/8 = 4

64/16 = 4

Answer:

1:4

2:8

8:32

16:64

Step-by-step explanation:

The constant of proportionality is 1:4. Whatever number is on the right has to  be 4 times greater than the number on the left for it to be proportional. I divided 32 by 4 to get 8 on the first one, and I multiplied 16 by 4 on the second one to get 64.

Hope this helps!

Answer: distributing

2(6x + 6) is 12x + 12

16x - 8 is 8(2x - 1)

3(x - 2) is 3x - 6

3(4x + 4) is 12x + 12

2x + 6 is 2(x + 3)

4(x + 3) is 12x + 12

Step-by-step explanation:

Distribute the number in front of the parenthesis to the numbers inside the parenthesis .

for example: 3(x-2)

3 times x = 3x

3 times -2= -6

Step-by-step explanation:

The quotient of given numbers is 6.4.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, dividend =70.4 and divisor=11.

The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Here, 70.4/11

= 6.4

Therefore, the quotient is 6.4.
