The sum of fifteen and six times a number t is eighty one

Answers

Answer 1
Answer:

The number is 11.

What is an equation?

"It is a mathematical statement which consists of equal symbol between two arithmetic expressions."

For given question,

the sum of fifteen and six times a number t is eighty one.

We write above statement in equation form as,

15 + 6t = 81

We solve above equation to find the number t.

⇒ 15 + 6t = 81

⇒ 15 + 6t -15 = 81 - 15       .....................(Subtract 15 from both the sides)

⇒ 6t = 66

⇒ (6t)/(6) = (66)/(6)                             ....................(Divide both the sides by 6)

⇒ t = 11

Therefore, the number is 11.

What does 2/3 + 4/5 equal?

Answers

First, find common denominators.

2/3 → 10/15

4/5 → 12/15

Second, add.

10/15 + 12/15 = 22/15

Third, turn into a mix number if needed.

22/15 = 1 7/15

Best of Luck!

Answer:

6/12

Step-by-step explanation:

2/3+4/5

find the common denominator

3:3,6,9,12

4:4,8,12

so its 12

so add them 2/12+4/12

There were 200 people at the baseball game. Each of them bought a $8 ticket to get into the game. How much money did the people spend on baseball tickets for the game?

A.
$25

B.
$250

C.
$1,600

D.
$1,800

Answers

The answer is C. $1,600 because you multiply 200 by the cost of the ticket.
C because you do 8 multiplied by 200 to get 1600

Answers

Answer:

7)   40

8)   23

9)   63

Step-by-step explanation:

180 degrees in a triangle.  Add the 2 degrees they give you, and then subtract that from 180 to find the missing angle.

82 + 58 = 140    180 - 140 = 40

115 + 42 = 157    180 - 157 = 23

27 + 90 = 117     180 - 117 = 63

Hope this helps.

Answer:

7=40, 8=23, and 9=63

Step-by-step explanation:

The key info to solve is that in a triangle there are 180 degrees

7) we add 82 and 58 and then subtract the total from 180 to find x

=82 + 58 = 140, and 180 - 140 = 40, so 40=x

We do the same for the rest

115 + 42 = 157, and 180 - 157 = 23, so 23=x

Wait whats that square in the triangle? It represents 90 degrees, a right angle!

so, 27 + 90(right angle) = 117, and 180 - 117 = 63, so 63=x

In a parallelogram, if the measure of y is 32 degrees what is the measure of w

Answers

Talking about a parallelogram, we know that:
opposite sides and angles are congruent
in the picture below:
∠A = ∠C
AD = BC
if one angle is right, then the rest are right as well (making it a rectangle/square)
The consecutive angles are supplementary (meaning they add up to 180)
A + D = 180°

If y and w are consecutive angles, then 
w = 180 - 32
    =148°
If they are opposite angles, w = 32° (congruent angles)
