which of the following is the solution to the equation 25(z-2 )= 125?

A. z= 5.5
B. z = 3.5
D. z = -2.5
E. z = -0.5

Answers

Answer 1

Answer:

The answer is z = 7.

Step-by-step explanation:

1) Divide both sides by 25.

[tex]z - 2 = \frac{125}{25} [/tex]

2) Simplify 125/25 to 5.

[tex]z - 2 = 5[/tex]

3) Add 2 to both sides.

[tex]z = 5 + 2[/tex]

4) Simplify 5 + 2 to 7.

[tex]z = 7[/tex]

Thus, the answer is z = 7.

During a walk a thon,noahs time in hours was,t,and distance in miles,d,are related by the equation 1/3d=t .A gragh of the equarion includes points (12,4)

Answers

Question:

During a walk-a-thon, Noah's time in hours was t, and distance in miles, d, are related by the equation [tex]\frac{1}{3}d = t[/tex].  A graph of the equation includes points (12,4).

1. Identify the independent variable.

2. What does the point (12,4) represent in this situation?

3. What point would represent the time it took to walk [tex]7\frac{1}{2}[/tex] miles?  

Answer:

(a) d

(b) He spent 4 hours to walk 12 miles

(c) [tex](7\frac{1}{2},2\frac{1}{2})[/tex]

Step-by-step explanation:

Given

[tex]t = \frac{1}{3}d[/tex]

Solving (a): The independent variable

The independent variable, in this problem is the distance walked. Because the distance walked stands alone, and it is when the distance is known, that the time spent is known.

Hence:

The independent variable is distance (d)

Solving (b): What (12, 4) represents

This implies that:

[tex]distance = 12[/tex]

[tex]time\ spent = 4[/tex]

So: He spent 4 hours to walk 12 miles

Solving (c): Point to represent the time to walk [tex]7\frac{1}{2}[/tex] miles

This implies that:

[tex]d = 7\frac{1}{2}[/tex]

Substitute [tex]d = 7\frac{1}{2}[/tex] in [tex]t = \frac{1}{3}d[/tex]

[tex]t = \frac{1}{3} * 7\frac{1}{2}[/tex]

Express as improper fraction

[tex]t = \frac{1}{3} * \frac{15}{2}[/tex]

[tex]t = \frac{5}{2}[/tex]

Express as mixed number

[tex]t = 2\frac{1}{2}[/tex]

So: The point is, [tex](7\frac{1}{2},2\frac{1}{2})[/tex]

Edith rides in an Oober that charges a flat rate of $6.75 plus $3.20 per mile. If the ride share service charges $40.03 in total for her trip, how many miles is her ride? Enter your NUMERICAL answer only in the box as a decimal to the nearest tenth of a mile.

Answers

Answer:

10.4 miles

Step-by-step explanation:

c(m) = trip cost

c(m) = 6.75 + 3.2m

40.03 = 6.75 = 3.2m

33.28 = 3.2m

m = 10.4

2 more than the product of 3 and a number is -10.

Answers

Answer:

-4

Step-by-step explanation:

2 more than the product of 3 and a number is -10 can be written as 3x+2=-10.

we can take this equation and solve it, first subtracting 2 from both sides to get 3x=-12.

now we divide both sides by 3 to get x=-4, so the answer is -4.
