“Write an equation and solve for the unknown” I know it’s a lot but can someone help me with this

Answers

Answer 1

Answer:

g) x = 30

h) x = 30

i) m = 55

j) x = 24

k) k = 45

Step-by-step explanation:

all angles of a triangle add up to 180.

the square in the bottom right of the triangle is 90 btw

2x + x + 90 = 180

3x + 90 = 180

3x + 90 - 90 = 180 - 90

3x = 180 - 90

3x = 90

3x/3 = 90/3

x = 30

this is an Isosceles triangle.

that means the bottom two angles are equal.

75 + 75 + x = 180

x + 150 = 180

x + 150 - 150 = 180 - 150

x = 180 - 150

x = 30

2m is supplementary to the bottom right angle of the triangle.

that means they add together to make 180.

80 + 30 + (180 - 2m) = 180

110 - 2m = 180 - 180

110 - 2m = 0

110 = 2m

110/2 = m

55 = m

to save time I'm not going to write out the steps, its the same as the i.

2x + 3x + (180 - 120 ) = 180

5x + 60 = 180

5x = 180 - 60

5x = 120

x = 120/5

x = 24

imagine this as a triangle and a square.

sorry I'm not sure how to explain this -.-

but the equation would be

k + k + 90 = 180

2k + 90 = 180

2k = 180 - 90

2k = 90

k = 45

Im not sure how to solve this, I'm sorry :( hope you figure it out!

If 7/9x - 4/9x = 1/4 +5/12
what is the value of x?

Answers

Answer:

x=2

Step-by-step explanation:

subtract 7/9x -4/9x

3/9x= 1/4 +5/12

first change 1/4 to 3/12

then add 3/12 + 5/12

3/9x = 8/12

change 3/9x to 1/3x then to 4/12x

4/12x = 8/12

then mulitiply by the reciprical 12/4 on both sides

x = 2

Three consecutive odd numbers sum to 1,245. What are the three numbers?

Answers

Answer:

413, 415, 417

Step-by-step explanation:

Answer:

414, 415, 416

Step-by-step explanation:

Consecutive numbers means they come one after another, like 1,2,3,4,5... So they all follow the formula x, x+1, x+2, x+3...x+n.

Since there are 3, we can say that x+(x+1)+(x+2)=1,245.

Simplify that to 3x+3=1,245, and then subtract 3 from both sides.

We get 3x=1,242. Divide that by 3, and you get x=414.

Add 1 and 2 to 414, and you get 414, 415, and 416.

You can add them up to check.
