Pls help! I don’t get this, 7th grade math, Lesson 8 Unit 2

Answer:

it would be helpful if there was a diagram but ill write a proof below of how I would solve a problem. however, it may not be what ur looking for as the question is unclear

1) AB=CD - given

2) BC = BC - reflexive

3) AB+BC=CD+BC- addition property of equality

4)AC= BD - substitution

Answer:

Step-by-step explanation:

-3/8y = -24

-3y = -24 (8)

y = -192 / -3

y = 64

Answer:

4 hours  

Step-by-step explanation:

16/4= 4

Answer:

1. add 14 to both sides

b/2 = 8E + 14

2. multiply both sides by 2

b = (8E + 14) x 2

3. regroup terms

b = 2(8E + 14)

Hope this helped :)

Answer:

what is the question

Step-by-step explanation:

Answer:

12x + y = 16

Step-by-step explanation:

Standard Form: Ax + By = C

Step 1: Write point-slope form

y + 4 = -12(x - 1)

Step 2: Find slope-intercept form

y + 4 = -12x + 12

y = -12x + 16

Step 3: Find standard form

12x + y = 16

Answer:

X = 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

13x+59=11x+63

13x-11x=63-59

2x=4

x=2

13*2+59=26+59=85

11*2+63=22+63=85

360-85*2=2z

190=2z

z=95

It will be nice if you give me brainliest.Good luck!

Have a wonderful day!!!

Answer:

First, remember the definition of a vertical contraction/dilation.

If we have a function f(x), and we dilate it with a factor A, such as:

g(x) = A*f(x).

If A is larger than 1, then we are dilating the graph of f(x)

if A is smaller than 1, then we are contracting the graph of f(x).

In this case we have:

f(x) = x + 10 and g(x) = 0.3*f(x) = 0.3*x + 0.3*10 = 0.3*x + 3.

A = 0.3

then we have a contraction.

From this, we can conclude that the effects of this transformation in the graph will be that the graph of g(x) will be a vertical contraction of the graph of f(x).

(Where contracting means that in a given interval [x1, x2] the associated interval [f(x1), f(x2)] will be larger than [g(x1), g(x2)])

Below you can see both graphs, and see the difference between them, where green is f(x) and blue is g(x)

Step-by-step explanation:

Answer:

so here we are told that angle CED is 39 degrees and in this diagram we have three angles the first one is Angle CED the next one is angle CEL and the last one is angle LED so angle c e l + angle LED is equals to angle c e d so in this case 3 x - 6 + x + 25 should be equal to 39 degrees collect the like terms 3 x + x + 25 - 6 is equals to 39 degrees 4X + 19 is equals to 39 cross the 19 over the equals sign that you have 4 x is equals to 39 + 19 4 x is equals to 68 divide both sides by 4 and x is equals to 17 then substitute replace where there is x with seventeen so in this case angle c e l will be 3 * 17 -6 we are multiplying 3 by 17 because it was 3 x and we got the value of x to be 17 so 3 * 17 is 51 -6 is 45 so angle CEL is 45 degrees you can do the same with the other angle that is angle LED and you get x to be 42

The answer is 405 because if you multiply 3 and 135 that would lead you to your answer.

Answer:

x = 6 or x = -5

Step-by-step explanation:

x^2 - 30 = x

x^2 - x - 30 = 0

(x - 6)(x + 5) = 0

x - 6 = 0 or x + 5 = 0

x = 6 or x = -5

Answer:

by BPT it will be solved

Step-by-step explanation:

CQ/QA=CP/PD

x+2/x=5x+4/3x

by cross multiplication

answer will be 1

Parallel sides are sides that are equidistant from one another. The value of x is 1

Given that:

[tex]CQ = x + 2\\QA = x\\CP = 5x + 4\\PD = 3x[/tex]

Since:

QR & AB are parallel, and RP & BD are parallel.

Then by theorem of similarities:

[tex]\frac{CQ}{QA} = \frac{CP}{PD}[/tex]

This gives:

[tex]\frac{x+2}{x} = \frac{5x + 4}{3x}[/tex]

Multiply both sides by 3x

[tex]3x \times \frac{x+2}{x} = \frac{5x + 4}{3x} \times 3x[/tex]

[tex]3 \times (x+2) = 5x + 4[/tex]

Open bracket

[tex]3x+6 = 5x + 4[/tex]

Collect like terms

[tex]5x - 3x = 6 -4[/tex]

[tex]2x = 2[/tex]

Divide both sides by 2

[tex]x = 1[/tex]
