I have to find the angle measurements of a interior triangle a is 4x b is 7x-2 and c is 5x-10

Mathematics
1 answer:
RSB [31]3 years ago
5 0

Answer:

m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle a+m\angle b+m\angle c=180^o

substitute the given values

4x^o+(7x-2)^o+(5x-10)^o=180^o

solve for x

(16x-12)^o=180^o

16x=180+12\\16x=192\\x=12

Find the angle measurements

m\angle a=4(12)=48^o

m\angle b=7(12)-2=82^o

m\angle c=5(12)-10)=50^o

What can be an equation of the line with a slope of −7 that passes through the point (−3,12).
laiz [17]

Answer:

y=-7x-9

Step-by-step explanation:

y=mx+b(where m is slope and b is y intercept)

y=-7x+b

plugging the number in we get

12=-7(-3)+b

12=21+b

b=-9

so y= -7x-9

John weighs three times as much as Karen. Two times John's weight plus Karen's weight is 875 pounds. How much does John weigh? H
Leokris [45]

Answer:

John- 375

Karen- 125

Step-by-step explanation:

Answer 1...

j =3k

2j + k = 875

substituting the first eqn into the 2nd

2(3k) + k = 875

6k+ k =875

7k = 875

k =875/7 =125

thus j = 3(125) =375

The diagram shows a cuboid.<br> 4 cm<br> 5 cm<br> 9 cm<br> What is the surface area of the cuboid?
katrin2010 [14]

Answer:

202 cm^2

Step-by-step explanation:

SA = 2LW + 2LH + 2WH

SA = 2(4 cm)(5 cm) + 2(4 cm)(9 cm) + 2(5 cm)(9 cm)

SA = 40 cm^2 + 72 cm^2 + 90 cm^2

SA = 202 cm^2

Salomon tracks the weight of his new puppy every 2 weeks. She weighs 10 lbs the
Gekata [30.6K]

Equation (B) "y = 3x + 10" represents the growth of the puppy.

<h3>What are equations?</h3>
  • An equation is a mathematical formula where the "equal to" sign appears between two expressions having the same value.
  • Like 3x plus 5 equals 15, for example.
  • Different types of equations exist, such as linear, quadratic, cubic, and others.
  • The three primary forms of linear equations are the slope-intercept form, standard form, and point-slope form.

So, the equation that represents the situation:

  • The weight increase is: (10, 13, 16, 19, 22, 25)
  • We can observe that every time, there is a rise of 3lbs of weight.
  • Now, let 10 be a constant as the weight is starting from 10 lbs.
  • And 'x' be the number of time Salomon tracks the weight.

Then:

  • y = 3x + 10

For example, Salomon checks the weight for the 6th time then:

  • y = 3x + 10
  • y = 3(5) + 10
  • y = 15 + 10
  • y = 25

So, the equation is correct.

Therefore, equation (B) "y = 3x + 10" represents the growth of the puppy.

The correct question is given below:
Salomon tracks the weight of his new puppy every 2 weeks. She weighs 10 lbs the day he brings her home. His list for her first 6 "weighs" is as follows: (10, 13, 16, 19, 22, 25}

Which equation represents the growth of the puppy? Select one:

A. y = x + 3

B. y = 3x + 10

C. y = 10x + 3

D. y = x + 10
