5(1 - 2x) = -65
( Multi- Step equations)
Please help:)<3
show steps if you can thank you!:)<4​

Answers

Answer 1

Step-by-step explanation:

5(1-2x) = -65

5-10x = -65

65+5 = 10x

70 = 10x

7 = x

x = 7

Answer 2

Answer:

X=7/2

Step-by-step explanation:

5(1 - 2x) = -65

5-20x=-65

-20x=-65-5

-20x=-70

Minus sign cancel from both side

So x=70/20

X=7/2

Given SD HT; SH=ST prove SHD= STD

Answers

Answer:

Δ SHD ≅ Δ STD (By SAS)

Step-by-step explanation:

Given:

SD⊥HT

SH=ST

Prove:

Δ SHD ≅ Δ STD

Computation:

SH=ST (Given)

SD = SD (Common)

∠SHD = ∠SDT (right angle) (SD⊥HT)

So,

Δ SHD ≅ Δ STD (By SAS)

The proof of [tex]\Delta SHD\cong \Delta STD[/tex] is given below.

Given, SD is perpendicular to HT.

We have to prove [tex]\Delta SHD\cong \Delta STD[/tex].

Now, In [tex]\Delta SHD\ and\ \Delta STD[/tex],

[tex]\angle SDH=\angle SDT[/tex] ( since SD perpendicular to HT, so both will be 90 ).

[tex]SH=ST[/tex] ( given in question ).

[tex]SD= SD[/tex] ( common side in both the triangle ).

So, by Right angle hypotenuse congruence rule,

[tex]\Delta SHD\cong \Delta STD[/tex].

Hence the [tex]\Delta SHD\cong \Delta STD[/tex] proved above.

Tyler is going on a hiking trip. At the end of the
first day he has 7,250 feet left to climb. He plans
to climb 400 feet each day.

Write an explicit formula to model the situation.

At the end of which day does Tyler have 1750
feet left to climb?

Answers

Answer:

 (1) F(n)  =  8050 -400n  

 (2) 16 days

Step-by-step explanation:

Tylor  first day he has left 7,250feet left to climb, this means that he has already climbed his 400ft on his first day

This will produce an arithmetic series for the distances left to climb as each day passes

initial climb = 7,250+400 = 7,650

Arithmetic Series

7650 , 7250 , 6850 , 6450 ......

a = 7650 , d = -400

(1)  Explicit formula

F(n) = a + (n-1)d

        =  7650 + (n-1)(-400)

        = 7650 +400 -400n

    F(n)  =  8050 -400n  

(2) 8050 -400n = 1750

      6300 = 400n

         n = 6300 /400 = 15.75 = 16 days( approximately)

So after 16days (approximately) Taylor will have 1750ft left to climb.

Answers

Answer:

Common multiplier = 10, Equal simplest forms = 1/2

Step-by-step explanation:

Ratio 10 / 20 & 30 / 60 have common multiplier 10.

As 10, 20, 30, 60 are all multiples of 10.

These ratios are equal, as 10/20 = 30/60 = 1/2 (their simplest form)

Answer:   Perimeter of triangle ROA = 33

=================================================

Explanation:

Points R, O, and A are midpoints of sides XY, YG, and XG respectively.

Because of this, we know that the points cut those sides into two equal halves.

To elaborate, we know the following three facts:

Point R is the midpoint of XY, so XR = RYPoint O is the midpoint of YG, so YO = OGPoint A is the midpoint of XG, so XA = AG

The diagram shows that YO = 14, so OG must be 14 units long as well.

The diagram also shows XA = 8. Since XA = AG, we know that AG = 8.

-----------------------------

Use this information to find the perimeter of triangle XYG.

Perimeter of XYG = sum of all the sides

Perimeter of XYG  = (XY) + (YG) + (XG)

Perimeter of XYG  = (22) + (YO+OG) + (XA+AG)

Perimeter of XYG  = 22 + (14+14) + (8+8)

Perimeter of XYG  = 66

-----------------------------

Then we cut this in half to get the perimeter of triangle ROA.

We do this because each segment of ROA is half that of the corresponding segment of XYG. The midsegments (RA, RO, AO) are cut in half and are parallel to the opposite side.

So,

Perimeter of ROA = (1/2)*(Perimeter of XYG)

Perimeter of ROA = (1/2)*(66)

Perimeter of ROA = 33
