Which of the following is a solution to the equation y = 3x - 1 ?

1 answer:

8 0

One way of determining the answer is by substituting the values to the equation. It is done as follows:

A. (4,1)
y = 3x - 1
1 = 3(4) - 1 = 11 -------> not equal

B. (2,5)
y = 3x - 1
5 = 3(2) - 1 = 5 --------> equal

C. (4,3)
y = 3x - 1
3 = 3(4) -1 --------------> not equal

D. (0, -3)
y = 3x - 1
-3 = 3(0) -1 = -1 ---------> not equal

Hector is dividing students into groups for a nature hike. He wants to divide the boys and girls so that each group has the same

Zolol [24]

Answer: The students can be divided into 7 groups.

Each group will have 3 boys and 8 girls.

Step-by-step explanation:

There are 21 boys and 56 girls.

To divide them so that each group has the same number of both boys and girls.

We find GCD(21,56).

21 = 3 x 7

56 = 2 x 2 x 2 x 7

GCD (21,56) = 7

So, the students can be divided into 7 groups.

Number of girls in each group = $\dfrac{56}{7}=8$

Number of boys in each group = $\dfrac{21}{7}=3$

So, each group will have 3 boys and 8 girls.

Mr. West is painting his front sidewalk to make it colorful. The total area is 24 square feet. What are the possible dimensions

ryzh [129]

Answer:

All possible dimensions are: 1ft × 24ft = 24 $ft^{2}$ , 2ft × 12ft = 24 $ft^{2}$ , 3ft × 8ft = 24 $ft^{2}$ , 4ft × 6ft = 24 $ft^{2}$ , 6ft × 4ft = 24 $ft^{2}$ , 8ft × 3ft = 24 $ft^{2}$ , 12ft × 2ft = 24 $ft^{2}$ , or 24ft × 1ft = 24 $ft^{2}$ .

Step-by-step explanation:

With the assumption that the sidewalk has a rectangular shape:

Area of a rectangle = length × width

From the question, the total area = 24 $ft^{2}$ .

⇒ length × width = 24 $ft^{2}$

So, all possible combinations are:

i. 1 ft × 24 ft = 24 $ft^{2}$

ii. 2 ft × 12 ft = 24 $ft^{2}$

iii. 3 ft × 8 ft = 24 $ft^{2}$

iv. 4ft × 6 ft = 24 $ft^{2}$

v. 6ft × 4ft = 24 $ft^{2}$

vi. 8ft × 3ft = 24 $ft^{2}$

vii. 12ft × 2ft = 24 $ft^{2}$

viii. 24ft × 1ft = 24 $ft^{2}$
