Answer:

t=-2

Step-by-step explanation:

(t+9)20=140

Distribute the 20

20t +180 = 140

Subtract 180 from each side

20t +180-180 = 140-180

20t = -40

Divide by 20

20t/20 = -40/20

t=-2

Answer:

-2


Step-by-step explanation:

(t+9)20 = 140

Open the bracket first by multiplying everything by 20.

(20×t) + (20×9) = 140

20t + 180 = 140

20t + 180 - 180 = 140 - 180

20t = -40

20t/20 = -40/20

t = -2

MATH DETECTIVE:
sergeinik [125]

Answer:

- 5

Step-by-step explanation:

"I am a negative integer greater than -6."

This eliminates any number that is less than -6, as well as any positive number.

0 > x > -6

"I am less than -2."

This narrows down the possible numbers to:

-5, -4, -3.

"I am not equal to -2 + (-1)"

-2 + - 1

-2 - 1

- 3

The number is not '-3'.

"I am not equal to 2 - 6."

2 - 6

- 4

The number is not -4.

Your number should be -5.

Hope this helps.

What is the surface area of the square pyramid?
Pavel [41]
The base is a square, therefore all the sides of the base  are the same. This also means all the triangles have the  same area.

10*10 = 100 cm^2 for the base

0.5*10*12 = 60 cm^2 for each triangle

100 + 4(60) = 340 cm^2
