7d + d - 4d - 7 = 5d

8d - 4d - 7 = 5d

4d - 7 = 5d

5d = 4d - 7

Subtract sides 4d

- 4d + 5d =  - 4d + 4d - 7

d =  - 7

Thus the correct answer is Option three.

Dimas [21]

Answer:

57\%

Step-by-step explanation:

Given: Number of students who were given Cardinal Credits last week for good behavior = 14

Number of students who were given Cardinal Credits this week for good behavior = 22

To find: percent increase in number of students who were given Cardinal Credits

Solution:

Increase in number of students = 22 - 14 = 8

Percent increase in number of students who were given Cardinal Credits = Increase in number of students / Number of students who were given Cardinal Credits last week for good behavior  × 100 =\frac{8}{14}\times 100=57.14\approx 57\%

Input value for the function machine that gives an output value of 3.
krek1111 [17]

Answer:

x = –1

Step-by-step explanation:

From the question given above, the following data were obtained:

y = √(–2x + 7)

y = 3

x =?

The value of x can be obtained as follow:

y = √(–2x + 7)

3 = √(–2x + 7)

Take the square of both side

3² = –2x + 7

9 = –2x + 7

Collect like terms

9 – 7 = –2x

2 = –2x

Divide both side by –2

x = 2 / –2

x = –1

#10-1 : What is the probability of randomly choosing a diamond card from a regular deck of 52 cards? What is the probability of
Alchen [17]

\huge{\boxed{\frac{1}{4}}}\ \ \huge{\boxed{\frac{1}{4}}}

There are 13 of each suit in a deck of 52 cards.

This means the probability of drawing a diamond card is \frac{13}{52}. You can divide the numerator and denominator each by 13 to simplify. \frac{13}{52} \div \frac{13}{13} = \boxed{\frac{1}{4}}

Since there are the same number of clubs as there are diamonds, the probabilities are the same.
