WORTH MANY POINTS PLEASE HELP..

Quincy paid $9.50 to join a photography club that allows him to print digital pictures for 0.20 each. So far he has paid $12.50 to the club. Write and solve an equation to work out how many pictures Quincy has paid for.

Answers

Answer 1

Answer:

9.50 + 0.20e = 12.50

Step-by-step explanation:

you start with the 9.50, base price. Then with every photo you pay 0.20, since we don't know how many it is we put a variable. Then we know that those two combined is 12.50, so yeah.

Answer 2

Answer:

Step-by-step explanation:

Total Cost = base price + 0.20*x Where x is the number of prints printed.

12.50 = 9.50 + 0.20x Subtract 9.50 from both sides.

12.50 - 9.50 = 0.20x

3 = 0.20x Divide by 0.20

3/0.20 = x

x = 15

So he printed 15 prints.

find the value of a if the line joining the points (3a,4) and (a,-3) has a gradient of 1

Answers

Recall that the slope or gradient of a line segment through two points is the ratio of the change in the y coordinate to the change in the x coordinate.

If the gradient is 1, then

1 = (-3 - 4) / (a - 3a)

Solve for a :

1 = -7 / (-2a)

1 = 7/(2a)

2a = 7

a = 7/2

6.7x10 =

Answers

Answer: 67

Step-by-step explanation:

When you multiply with numbers like 10, 100, 1000, 10000, and so on you just have too right or left (division : left)(multiplication : right) according to the zero's. Like 100 has 2 zero's so then if you're multiplying with that you will go 2 to the right, and dividing you will go 2 to the left. Lets apply the same logic here, the question is 6.7 x 10, 10 has 1 zero and we are multiplying here so then, we have to go to the right, so 6.7 will become 67.

What is 3/4 divided 1/2

Answers

Answer:

.375

Step-by-step explanation:

When you divide by a fraction, you end up multiplying by the reciprocal:

3/4 ÷ 1/2 = 3/4 • 2/1

Now that it’s multiplication, you multiply straight across.

3•2 / 4•1 = 6/4

Then remember to reduce. Since both 6 and 4 are divisible by 2, divide both by 2.

6/4 = 3/2

Help what is the slope of the line?

Answers

9514 1404 393

Answer:

8/5 = 1.6

Step-by-step explanation:

It looks like the line crosses grid points (-4, -4) and (1, 4). This means the slope is ...

m = (y2 -y1)/(x2 -x1)

m = (4 -(-4))/(1 -(-4)) = 8/5 = 1.6

The slope of the line seems to be about 8/5, or 1.6.

The words above say “the expression x-2 has a value of -5 for some value of x. For the same value of x, what is the value of the expression (x-2)*squared. Show your reasoning for this problem.” Also i said (*squared) bcuz its squared with a 2 so please dont leave that part out. D: help pls

Answers

Answer:

(1)

Step-by-step explanation:

x - 2 = - 5 Add 1 to each side

x = - 5 + 2

x = - 3

Now go to the next part

(x - 2)^2

(-3 - 2)^2

(- 5)^2

Now it's a good idea at this point to separate the squared. It means that two numbers that are the same are to be multiplied together.

(-5)(-5) Two minuses are going to give you a plus.

5 * 5 = 25

(-5) * (-5) also give you 25
