Answer:

y=9/2x+2

Step-by-step explanation:

Answer:

x=2/9y + -4/9

Step-by-step explanation:

Solve for x:

2y−9x=4

Add -2y to both sides:

−9x+2y+−2y=4+−2y

−9x=−2y+4

Divide both sides by -9:

−9x /−9 =−2y+4 /-9

Then your answer is:

x= 2 /9 y+ −4/ 9

Answer:

5b; when b=3.4 the distance Sandra rode is 17 miles.

Step-by-step explanation:

Given that:

Sandra rode her bike 5 times as many as miles as Barbara.

It means that 5 will be multiplied by the distance rode by Barbara.

Distance by Sandra = 5b

When b=3.4 miles

Distance by Sandra = 5(3.4)

Distance by Sandra = 17 miles

Hence,

5b; when b=3.4 the distance Sandra rode is 17 miles.

Answer:

b

Answer:

225

505

Step-by-step explanation:

Answer:

157.5 and 505

Step-by-step explanation:

1.5 * 105

you can times both by 10 to get whole number

15*105 = 1575

add the decimal back

157.5

5 * 101 = 505

Answer:

D.117 square in

Step-by-step explanation:

We are given that

Side length of square A=6 in

Side length of square B=9 in

We have to find the area of square C if the tree squares create a right triangle.

By using Pythagoras theorem

[tex](hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2[/tex]

Side of square C

[tex](Hypotenuse)^2=6^2+9^2[/tex]

[tex](Hypotenuse)^2=117[/tex]

[tex]Hypotenuse=\sqrt{117}[/tex]

Now,

The area of square C=[tex](side)^2[/tex]

The area of square C=[tex](\sqrt{117})^2=117 in^2[/tex]

Option D is true.

Answer:

D 10x=150

Step-by-step explanation:

They are the same degree so they must equal eachother

Answer:

10x=150(Vertically Opposite Angle)

Answer:

x=9

x=0

x=-14

x=27

x=12

Step-by-step explanation:

Answer:

solution :

in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.

now ,

in rt angle tirangle ADC,

angleACD=45 degree, angle DAC=45 degree now,

in triangle ABD,

angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)

angle BAD+75+30=180

angle BAD=180-165      therefore,angle BAD=15

angle BAC =15+45=60

Area of triangle ABC=1/2×AB×AC×SIN 60

=1/2×10.2×14×√3/2

=61.83cm³ ans

Answer:

a) missing exponent is 8

b) missing exponent is -5

c) missing exponent is 15

d) missing exponent is 6

Step-by-step explanation:

for 'a' and 'b' you have to ADD the exponents

for 'c' you have to SUBTRACT the exponents

for 'd' you have to MULT the exponents

let 'n' = missing exponent

a) -5 + n = 3

    n = 8

b)  3 + n = -2

    n = -5

c) n - 6 = 9

   n = 15

d) 5n = 30

    n = 6

Let x = 0.555…

Then 10x = 5.555…

Subtract one from the other to get

10x - x = 5.555… - 0.555…

Notice how the fractional parts on the right cancel. This leaves you with

9x = 5

and so

x = 5/9

Answer:

59

Step-by-step explanation:

Since this fraction repeats the same number it must have a denominator of 9 and a numerator of the repeating digit the repeating digit is 5 so the fraction is 59

Answer:

percent error=6%

Step-by-step explanation:

Step one:

given data

Patty counted 250

The actual amount of chocolate chips on the tray were 265

Required

The percent error

Step two:

The formula is

percent error= actual-expected/expected*100

percent error= 265-250/250*100

percent error=15/250*100

percent error=0.06*100

percent error=6%

Answer:3,1

Step-by-step explanation:

Answer:

15 rentals

Step-by-step explanation:

Latest Releases Depot

rent = $3 per DVD

membership= free

let the number of DVD be x

let the expression for the total be

y= 3x----------------1

Video for You

rent= $2  per DVD

membership= $15

let the number of DVD be x

let the expression for the total be

y= 15+2x----------------2

equate 1 and 2

3x=15+2x

collect like terms

3x-2x=15

x= 15

Hence the number of DVDs needed for the two rentals to have the same amount is at least 15 rentals

Answer: the first answer choice or (6,4)

Step-by-step explanation:

where they intersect

Answer:

ya i can

Step-by-step explanation:

Answer:

F= 34 degrees (alternate angles are equal)

To find D

we first have to find the angles at AB

B =180- 165 (sum of angles on a straight line = 180°)

therefore B = 15°(we'll use this to find the angle at E)

A=34 (from the diagram)

so,

D = 180- (15 + 34) [sum of angles in a triangle = 180°]

D = 131°

E=15° (alternate angles are equal )

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

-2 + x = -x + 2

Isolate the variable

2x = 4

Simplify

x = 2

Answer:

x = 2

Step-by-step explanation:

you want to move the variables to one side, the numbers to the other side.

x = -x+4

then you move the other x

2x = 4

x = 2
