Answer:

x=82

Step-by-step explanation:

All triangles have interior angles that add up to 180 Degrees.

We already know one of the angles, and the other two are the same.

180-16=164

164/2=82

Answer:

x=82

Step-by-step explanation:

well it's an isosceles triangle(two sides of the same lenght) which means that the angles between these 2 sides and the 3rd one are also equal. 2x=180-16 x=82

Answer:

The Distributive Property.

Step-by-step explanation:

4(x - 1) = 12

When distributing out the 4, it must go to all the terms within the brackets like this:

4x - 4 = 12.

4x = 16

x = 4.

Answer:

It will take Greg 8 weeks to save up to buy the phone.

Step-by-step explanation:

Given equation is:

M = 90 + 15w

Here,

M represents the money saved

w represents the number of weeks

Greg wants to save 210

Putting M = 210 in the given equation;

210 = 90 + 15w

210 - 90 = 15w

15w = 120

Dividing both sides by 15

[tex]\frac{15w}{15}=\frac{120}{15}\\w = 8[/tex]

Hence,

It will take Greg 8 weeks to save up to buy the phone.

Answer:

Coordinates of X is (7/2,9/2)

Coordinates of C is (6,7)

Explanation:

x is the midpint of DB and AC

coordinates of X = ( (5+2)/2 ,(6+3)/2)

= (7/2,9/2)

Coordinates of X is (7/2,9/2)

Let (a,b) be the coordinates of C.

Then,

coordinates of x = ((a+1)/2, (b+2)/2)

(7/2,9/2) = ((a+1)/2, (b+2)/2)

Hence,

7/2=(a+1)/2

7=a+1

a = 6

9/2 =(b+2)/2

9 =b+2

b =7

Coordinates of C is (6,7)

Answer:

a) Interest = $980

b) Principal = $7250

c) Interest rate = 3%

Step-by-step explanation:

a) For Alex

How much interest (in dollars) will Alex receive after 2 years if he deposited $14,000 in the bank at 3.5% annual interest rate?

The formula for Simple Interest = PRT

Where

P = Principal = $14,000

R = Interest rate = 3.5% = 0.035

T = Time = 2 years

I = $14,000 × 0.035 × 2

I = $980

b) For Davit

Davit received $870 as an interest for money invested in Foreign Exchange Market three years ago. How much money did he invest, if the annual interest was 4%

The formula for Simple Interest = PRT

Where

P = Principal = ?

R = Interest rate = 4% = 0.04

I = $870

T = 3 years

years

Solving for P

P = I/RT

P = $870/0.04 × 3

P = $870/0.12

P = $7250

c) For Arthur

. For starting a new business, Arthur borrowed $23000 and calculated $3450 interest for five years. What annual interest was considered?

The formula for Simple Interest = PRT

Where

P = Principal = $23,000

R = Interest rate = ?

I = $3450

T = 5 years

years

We are Solving for R

R = I/PT

R = $3450/$23,000× 5

R = 3450/115000

R = 0.03

Converting to percentage

= 0.03 × 100

= 3%

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just don’t want to waste my time in case you don’t want me to :)

Answer:

m=1

Step-by-step explanation:

2m+7=9

subtract 7 on both sides

2m=2

divide 2 on both sides

m=1

hope it helped

Answer: m=1

Step-by-step explanation:

The constant is 7 and the coefficient is 2m. You would subtract 7 to both sides and then divide by 2 and you should get 1

sorry for that but this is right solution I have solve it now

Answer:

An equation of the line passing through (-2, 3) and perpendicular to the line 5x - y = 12 will be:

Step-by-step explanation:

Given the equation

[tex]5x - y = 12[/tex]

converting the line into the slope-intercept form y = mx+b, where m is the slope

[tex]-y = 12-5x[/tex]

[tex]y = 5x-12[/tex]

The slope of the line = m = 5

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

Therefore, the slope of new line = – 1/m = -1/5 = -1/5

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the slope of new line = -1/5 and (-2, 3)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-3=-\frac{1}{5}\left(x-\left(-2\right)\right)[/tex]

[tex]y-3=-\frac{1}{5}\left(x+2\right)[/tex]

Add 3 to both sides

[tex]y-3+3=-\frac{1}{5}\left(x+2\right)+3[/tex]

[tex]y=-\frac{1}{5}x+\frac{13}{5}[/tex]

Therefore, an equation of the line passing through (-2, 3) and perpendicular to the line 5x - y = 12 will be:

Answer:

73

Step-by-step explanation:

Use the PEMDAS method. Start off with exponents, which is 3x3, which equals 9. Then do multiplication, because it comes before addition. So you multiply 9 by 8 to get 72. Then it says +1 so 72+1 equals 73. (Final Answer)

Answer:

The solution is n=1

Step-by-step explanation:

I hope you mean

4/5n-3/5=1/5n

if so then here's the solution

5n×4/5n-3/5×5n=1/5n×5n

4-3n=1

4-1=3n

3n=3

n=1

Answer:

y= -4x+3
