if the sum of two expressions is 3x+5 and one expression is 5x-7 what is the other expression

Answers

Answer 1

Answer:

-2x + 12

Step-by-step explanation:

If we call our other expression y, we can set up an equation tying together 3x + 5, y, and 5x - 7:

[tex](5x-7)+y=3x+5[/tex]

Solving for y by subtracting 5x - 7 from both sides will get us the expression we're looking for:

[tex]y=3x+5-(5x-7)\\y=3x+5-5x+7\\y=-2x+12[/tex]

So the other expression in the sum is -2x + 12.

A towns population went from 40,000 to 50,000. What was the percent of change in the population?

Answers

Answer:

The percent of change in the population was of 25%.

Step-by-step explanation:

Percent change:

The percent change is given by the change multiplied by 100, and divided by the initial value.

A towns population went from 40,000 to 50,000.

Change: 50000 - 40000 = 10000

Initial value: 40000

10000*100/40000 = 25%

The percent of change in the population was of 25%.

Answers

Answer:

15

Step-by-step explanation:

use formula y-y1=m(x-x1)

(4,15) = (x1,y1)
(9,20)=(x2,y2)

m is the slope which you don’t have but you can find by doing (y2-y1)/(x2-x1)
m=(20-15)/(9-4)
m=5/5
m=1

y-y1=m(x-x1)
y-15=1(x-4)
y-15=x-4 |+15 to both sides
y=x +11

Answers

Answer:

A. 2

Step-by-step explanation:

Given:

DC = 1

CE = x + 4

AB = 11

BE = x + 1

Required:

Value of x

Solution:

(DC + CE) × CE = (AB + BE) × BE

(1 + x + 4) × (x + 4) = (11 + x + 1) × (x + 1)

(x + 5) × (x + 4) = (x + 12) × (x + 1)

x² + 4x + 5x + 20 = x² + x + 12x + 12 (distributive property)

x² + 9x + 20 = x² + 13x + 12

Collect like terms

x² - x² + 9x - 13x = - 20 + 12

-4x = -8

Divide both sides by -4

x = -8/-4

x = 2

Step-by-step explanation:

✔️(x + 35)° + 30° + 90° = 180° (sum of triangle)

x + 35 + 30 + 90 = 180

Add like terms

x + 155 = 180

x + 155 - 155 = 180 - 155

x = 25°

✔️(y + 30)° + 35° + 90° = 180° (sum of triangles)

y + 155 = 180

y = 180 - 155

y = 25°

2. The German Shepard actually weighs 28 pounds. Lisa thought the
dog weighed 44 pounds. What is the percent error?

Answers

Answer:

Lisa's percentage of error regarding the weight of the dog was 57.14%.

Step-by-step explanation:

Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:

28 = 100

44 = X

(44 x 100) / 28 = X

4,400 / 28 = X

157.14 = X

157.14 - 100 = 57.14

Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.

Step-by-step explanation:

If If you jog 8 times around a track that is 600 meters long, then 4.8  kilometers you  have covered

What is Unit of Measurement?

A Unit of measure is the actual unit in which the associated values are measured.

Given,

If you jog 8 times around a track that is 600 meters long,

We need to find how many kilometers you have covered.

8 times around a track that is 600

It means we have to multiply eight with six hundred.

8×600

=4800

We know that 1 km is 1000 m

So divide 4800 by 1000 to find in kilometers

4800/1000=4.8km

Hence If you jog 8 times around a track that is 600 meters long, Then 4.8  Kilometers you have covered.
