Answer:

25

Step-by-step explanation:

Alll angles of a triangle = 180 degrees

36+61 = 97

180-97 = 83

It means that the other angle will be of 83 degrees.

means

4x-17 = 83

So now, we can do transposition.

Let's transpose 17.

4x-17 = 83

Transpose 17

4x = 83+17

4x = 100

Now we will transpose 4.

x = 100÷4

x = 25

Answer:

Brian sold 35 tickets.

Step-by-step explanation:

42 x 5/6 = 35

To prepare 300 units of the 6% solution, the required number of units of 10% solution needed will be 180 units.

Let the number of units of 10% solution = t

We can set up the equation thus :

10% solution × number of units = (300 × 6%)

10% × t = 300 × 6%

0.1t = 0.06 × 300

0.1t = 18

Divide both sides by 0.1 ; to isolate t

0.1t / 0.1 = 18 / 0.1

t = 180

Therefore, 180 units of the 10% solution are required to prepare 300 units of 6% solution.

Step-by-step explanation:

bc i’m like that

The graph of the situation is shown below.

A graph is a diagram that depicts the relationship between two variables, usually measured along opposite axes in a pair.

Given that,

Jack eats half of the popcorn in 15 minutes,

Implies that, in starting 15 minutes, the graph will decrease,

For the next 30 minutes, Jake does not eat popcorn,

Therefore, the graph will be constant in interval of 30 minutes,

After that, Jack gradually eats the popcorn, so the graph will gradually decrease,

And at last Jack spills all the remaining popcorn instantaneously decrease

So the graph can be represented as given below.

Answer:

Neither

Neither because sometimes as x increases, y increases and sometimes as x increases, y decreases so this graph have no corrleation so it neither.

Answer:

45

Step-by-step explanation:

The required simplified value of the given expression a + b is given as 45.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

According to the question,
3(-2m + 5)-6(-4m-2) = am + b

-6m + 15 +24m + 12 = am + b

18m + 27 = am + b

From the comparison,
a = 18 and b = 27

Now,
a + b = 18 + 27
        = 45

Thus, the required simplified value of the given expression a + b is given as 45.

Answer: 76

Step-by-step explanation:

Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

[tex] - 1 = \frac{x - 3}{ 2} [/tex]

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

[tex] - 2 = x - 3[/tex]

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

[tex]1 = x[/tex]

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

Answer c -step explanation:

The recursive rule that best describes the sequence 3, 14, 36, 80, ...is [tex]a_{n} =2a_{n-1} +8[/tex].

A sequence is a particular order in which related things follow each other.

Let us cross-check the recursive rule [tex]a_{n} =2a_{n-1} +8[/tex]....(1)

Given sequence is: 3, 14, 36, 80, .....

Put n=1, 2, 3 in (1)

[tex]a_{2} =2a_1+8\\a_{2} =2*3+8\\a_{2} =14[/tex]

[tex]a_{3} =2a_2+8\\a_{3} =2*14+8\\a_{3} =36[/tex]

[tex]a_{4} =2a_3+8\\a_{4} =2*36+8\\a_{4} =80[/tex]

We are getting the sequence as 3, 14, 36, 80, ..... i.e. same as the given sequence.

Therefore, the recursive rule that best describes the sequence 3, 14, 36, 80, ...is [tex]a_{n} =2a_{n-1} +8[/tex].

Answer: Maybe x = -5

Step-by-step explanation: Your equation isn't making complete sense to me. But since it sounds like x+5 is in the denominator, if I had to guess, I'd say when x = -5. This is when the denominator equals 0. Since we can't divide by 0, it's an asymptote.

Answer:

g>5/8

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

-8g-6<-11

Step 2: Add 6 to both sides.

−8g−6+6<−11+6

−8g<−5

Step 3: Divide both sides by -8.

−8g/−8<−5/−8

= g<5/8
