Mathematics
1 answer:
kodGreya [7K]3 years ago
3 0

Answer:

The sentence written as an equation is 3x + 2 = 17

The solution is x = 5

Step-by-step explanation:

First, create the equation

2 more than 3 times a number x can be represented by 3x + 2

Set this equal to 17, to get the equation 3x + 2 = 17

Now, solve for x:

3x + 2 = 17

3x = 15

x = 5

So, the sentence written as an equation is 3x + 2 = 17

The solution is x = 5

Solve the proportion ASAP help do both questions
Strike441 [17]

Answer:

7. 4

8. 7

Step-by-step explanation:

7. \frac{1}{2} = \frac{x}{8}

Cross multiply

1*8 = x*2

8 = 2x

\frac{8}{2} = \frac{2x}{2} (division property of equality)

4 = x

x = 4

8. \frac{3}{x - 3} = \frac{6}{8}

Cross multiply

3*8 = 6(x - 3)

24 = 6x - 18

24 + 18 = 6x (addition property of equality)

42 = 6x

Divide both sides by 6

7 = x

x = 7

Three people are running for president of a class. The results of a poll indicate that the first candidate has an estimated 37%
lianna [129]

Answer:

0.19

Step-by-step explanation:

The are three candidate running for president and we know that probability of winning for first candidate and the probability of winning for second candidate and we have to find the probability of winning for third candidate

P(C1)=0.37

P(C2)=0.44

P(C3)=?

We know that sum of probabilities is always 1. So,

P(C1)+P(C2)+P(C3)=1

0.37+0.44+P(C3)=1

P(C3)=1-0.37-0.44

P(C3)=0.19

Thus, the probability of winning for third candidate is 0.19.

What is the perimeter of the parallelogram???
enot [183]
Answer: 22

explanation: the easiest way is to separate one of the diagonals into a triangle and use the pythagorean theorem.
a^2 + b^2 = c^2
4^2 + 3^3 = c^2
16 + 9 = c^2
25 = c^2
5 = c
you now know that both of the diagonals have a length of 5.
by counting the units on the two straight, you know that their length is 6.
6 + 6 + 5 + 5 = 22
