Answers

Answer:

The slope of the line is [tex] \frac{1}{2} [/tex].

Step-by-step explanation:

☆Remember:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

☆Just plug it in with 2 sets of coordinate points.

Two pencils and a ruler cost 98 cents in total. One pencil and 2 rulers cost $1.24 in total. Find the cost of each item.

Answers

Answer:

2.16

Step-by-step explanation:

r = cost of ruler

p = cost of pencil

r = 2p

6r + 15p = 2.16

Substitute 2p in place of r in 2nd equation and solve for p

6(2p) + 15p = 2.16

12p + 15p = 2.16

27p = 2.16

Answer: 2.16
6(2p)+15p=2.16
12p+15p=2.16
27p=2.16

please HELP MEEEEEE .A store owner wants to make a candy that sells for $1 per pound.he has 50 lb of sugar candies that cost $1.20 per pound.how many pounds of gummy candies that cost 80 cents per pound should he add.

Answers

Answer:

50 pounds

Step-by-step explanation:

we can use the equation 60+80/100x=1(x+50)

we get 80/100 x because the gummy candies are 80 cents or 80/100x

we get 60 from multiplying 1.20$ x 50 = 60

solve:

60+80/100x = x+50

60 = x-80/100x+50

60-50 = 20/100x

10 = 20/100x

x= 10 x 100/20 = 10x5= 50 pounds

Using proportions, it is found that he should add 50 pounds of gummy candies that cost 80 cents per pound.

What is a proportion?

A proportion is a fraction of a total amount.

This problem is organized as follows:

There is a total of 50 + x pounds.Of those, 50 cost $1.2 per pound.x cost $0.8 per pound.The selling price is of $1.

Hence:

[tex]\frac{50}{50 + x}1.2 + \frac{x}{50+x}0.8 = 1[/tex]

[tex]\frac{60 + 0.8x}{50 + x} = 1[/tex]

[tex]50 + x = 60 + 0.8x[/tex]

[tex]0.2x = 10[/tex]

[tex]x = \frac{10}{0.2}[/tex]

[tex]x = 50[/tex]

He should add 50 pounds of gummy candies that cost 80 cents per pound.

Which equation represents a line which is parallel to the line 7x - y = 4?

Answers

Answer:

Step-by-step explanation: step : Place the given line’s equation in slope- intercept form y = mx + b. A line parallel to this line will have the same slope.

7x - y = 4. Yields y = 7 x - 4. Therefore y = 7x - 5 is the correct answer.

solve for a
4(2a - 1) = -10(a - 5)

Answers

Answer:

A = 3

Step-by-step explanation:

8a-4=-10a+50

8a-4+4=-10a+50+4

8a=-10a+54

8a+10a=-10a+54+10a

18a=54

54 / 18 = 3

A = 3

the answer would be a=3. to put it more clear, multiply the number outside of the parenthesis. so for example 4•2a is 8a, and 4•-1 is -4. since the -4 has no variable, it would just be 8a-4. next, the -10 times a positive a would be -10a. a positive times a negative is negative. next, do -10•-5 which is positive 50. remember, a negative times a negative is positive! after this, take the 8a-4=-10a+50 and add the constant and the variable (-10a) by the 8a. ALWAYS go right to left when subtracting or adding. you should get 18a. so 18a-4=50. take the negative four and add a positive four because you need to make the sides equal, add the four to 50, and you should get 18a=54. lastly, 54/18 is 3! so, A=3
