188 to 42 what is the percent change
Mekhanik [1.2K]

Answer:

Step-by-step explanation:

so we are gonna have a percent decrease because it went from 188 to 42

decrease = (original number - new number) / (original number ) * 100

                = (188 - 42) / (188) * 100

                = (146 / 188) * 100

                = 0.7766 * 100

                = 77.66% decrease....not sure if u need ur answer rounded to the nearest percent or not....if so, its a 78% decrease

Adrian's computer cost 20% less than Jocelyn's computer. Adrian's computer cost $640. Adrian's computer cost 15% more than Corbi
OLEGan [10]

Answer:

640 = .8j

640 = 1.15c

Step-by-step explanation:

Let j = cost of Jocelyn's computer

c = cost of Corbin's computer

We know that Adrian's computer costs $640.

Since Adrian's computer costs 20% less than Jocelyn's computer, the cost of Adrian's computer is 80% of (.8 times)the cost of Jocelyn's computer, so 640 = .8j

Since Adrian's computer costs 15% more than Corbin's computer, the cost of Adrian's computer is 115% of (1.15 times) the cost of Corbin's computer, so 640 = 1.15c

-4(3 - 2x) + 2x = 2x4
topjm [15]

Answer:

x = 2

Step-by-step explanation:

-4(3 - 2x) + 2x = 2 x 4

-12 + 8x + 2x = 2 x 4

-12 + 8x + 2x = 8

-12 + 10x = 8

-12 + 12 + 10x = 8 + 12

10x = 20

\frac{10x}{10} = \frac{20}{10}

x = 2

Show all work to write the equations of the lines, representing the following conditions, in the form y = mx + b, where m is the
natima [27]
4x - 3y - 7 = 0
-3y = -4x + 7
y = 4/3x - 7/3....slope here is 4/3

A. a parallel line will have the same slope

y = mx + b
slope(m) = 4/3
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = 4/3(-2) + b
1 = -8/3 + b
1 + 8/3 = b
3/3 + 8/3 = b
11/3 = b

so ur parallel line is : y = 4/3x + 11/3

B. A perpendicular line will have a negative reciprocal slope. To get the negative reciprocal of a number, u flip the number and change the sign. So our perpendicular line will need a slope of -3/4

y = mx + b
slope(m) = -3/4
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = -3/4(-2) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b

so ur perpendicular equation is : y = -3/4x - 1/2
