Answer:

n=-6

Step-by-step explanation:

2(n+5)=-2

distribute

2(n+5)

2xn 2x5

2n+10

2n+10=-2

subtract 10 from both sides

10-10=0

-2-10=-12

2n=-12

divide each side by 2

2n/2=n

-12/2=-6

n=-6

Answer: x=4 hope this helps:)

Step-by-step explanation:

Answer:

x=-4

Step-by-step explanation:

9x-17=5x-1 isolate X

9x-17=5x-1 add +1 to each side of the equation 9x-17+1=5x-1+1 the ones cancels out... 9x-16=5x

add -9x to both sides..... 9x-16+9x=5x-9x...... 9x-9x-16=5x-9x

-16=5x-9x subtract 5x-9x

-16= - 4x divide both sides by -4

-4=x or x=-4

Answer:

X=2.5

Step-by-step explanation:

3x - 5 = 1/2x + 2x

3x - 1/2x - 2x = 5

1/2x = 5

X = 5 ÷ 1/2

X = 2.5

Answer:

[tex]y=-\frac{1}{3} x+5[/tex]

Step-by-step explanation:

This question is asking for slope-intercept form which is y=mx+b, where m is the slope and b is the y-intercept. First, find the slope; this can be done in two ways, counting change in y and x then dividing, or using the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. Either way for this graph the slope comes out as -1/3. Next, find the y-intercept, this is where the line intersects with the y-axis. In this case, the line touches the axis at 5, therefore 5 is the value of b.

Answer:

Rs 64000

Step-by-step explanation:

Since breadth B = 80% of length L, B = 0.8L

Perimeter, P = 2(L + B) = 360m

Substituting B = 0.8L into P, we have

2(0.8L + L) = 360 m

2(1.8L) = 360 m

3.6L = 360 m

L = 360m/3.6

L = 100 m

So, B = 0.8L = 0.8(100 m) = 80 m

The area of the rectangular ground is A = LB = 100 m × 80 m = 8000 m²

So, the cost of planting the ground at Rs 8 per m² is  Rs 8 per m² × 8000 m² = Rs 64000

Answer: 3) Not factorable

We cannot use the difference of squares method because we don't have a subtraction going on (ie "difference") and we don't have two perfect squares. The value 70 is not a perfect square.

We cannot factor out a GCF since the GCF here is 1, and that doesn't really affect things. Choice 4 is also not applicable because we don't have a trinomial. A trinomial has three terms.

I believe the answer is 13 ways to make 27 cents using Quarters, dimes, nickels, and pennies.

Step-by-step explanation:

Step-by-step explanation:

The 1st equation is in slope-intercept form.

=> Slope = 4

The 2nd equation is in point-slope form.

=> Slope = -1/4

Since their slopes are unequal,

The lines are not parallel to each other.

However the product of their slopes is -1,

Therefore the lines are perpendicular to each other.

The answer is the 2nd option.

Here,

amount (p) =10,000$

Time period (t)=2 years

Rate of interest (r)=12%

So,Intrest (I)

we know that,

[tex]\boxed{ I=\dfrac{p×t×r}{100 }[/tex]

According to the question,

I=⠀[tex]\tt{\dfrac{10000×12×2}{100} }[/tex] ⠀

=[tex]\tt{\dfrac{\cancel{10000}×12×2}{\cancel{100}} }[/tex] ⠀

=[tex]\tt{ 100×12×2 }[/tex] ⠀

=[tex]\tt{ 2400 }[/tex] ⠀

So,

2400$ intrest in 10000$in 12%for 2 years

Answer:

(3,7)

Step-by-step explanation:

x-3y=-2 -----equation i

x+3y=16-----equation ii

Subtract the two equations from each other

-6y=-18

-6y/-6=-18/-6

y=3

Substitute for x in equation i

x-3(3)=-2

x-9=-2

x=-2+9

x=7

x=7,y=3

Answer:

X is 7, and Y is 3.

Step-by-step explanation:

Step 1: Add 3y to both sides

x - 3y + 3y = -2 + 3y

x = 3y - 2

Step 2: Substitute 3y - 2 for x in x + 3y = 16

x + 3y = 16

3y - 2 + 3y = 16

Step 3: Simplify both sides of equation

6y - 2 = 16

Step 4: Add 2 to both sides

6y - 2 + 2 = 16 + 2

6y = 18

Step 5: Divide both sides by 6

6y/6 = 18/6

y = 3

Step 6: Substitute 3 for y in x - 3y = -2

x - 3(3) = -2

Step 7: Multiply 3 by 3 for 9

x - 9 = 2

Step 8: Switch sides!

x = 9 - 2

Step 9: Subtract 9 minus 2 to get 7

x = 7

With that we have our final answers: x = 7, and y = 3.

Answer:

the income tax paid for the last year is $900

Step-by-step explanation:

The computation of the income tax paid for the last year

Taxable income is $6,000

And, the 15% tax rate is charged for first $8,500

So the income tax paid is

= $6,000 × 15%

= $900

hence, the income tax paid for the last year is $900

The same is considered by doing the above calculation

Answer:

10a-3,7a-2,3a-9

1)4a+ 6a-3

10a -3

2)3a+ 4a -2

= 7a - 2

3) 2-3a+7

= 7+2-3a

= 9-3a

Heyyy friend.!!!! Hope it helps uh....

Answer:

x = 60

m∠G = 114 degrees

Step-by-step explanation:

In the given figure

∵ EFGH is a parallelogram

∵ ∠E and ∠G are opposite angles

→ By using the rule above

∴ m∠E = m∠G

∵ m∠E = (2x - 6)°

∵ m∠G = (x + 54)°

→ Equate them

∴ 2x - 6 = x + 54

→ Subtract x from both sides

∵ 2x - x - 6 = x - x + 54

∴ x - 6 = 54

→ Add 6 to both sides

∵ x - 6 + 6 = 54 + 6

∴ x = 60

→ Substitute the value of x in the expression of ∠G to find it

∵ m∠G = 60 + 54

∴ m∠G = 114 degrees
