Answer 1

Answer:

1. 5(3+9) = (5 x 3) + (5 x 9)

2. (7+8)6 = (6 x 7) + (6 x 8)

3. 51 x 9 + 51 x 31 = 459 + 1581 = 2040

4. 17 x 13 + 51 x 13 + 32 x 13 = 221 + 663 + 416 = 1300

These should all be right :)

I used PEMDAS and the distributive property.

Bryan has quarters and nickels in his piggy bank. He has three times as many nickels as he has quarters. If the total value of the coins is $12, find the number of nickels in the piggy bank.

Answers

Answer:

90

Step-by-step explanation:

Quarters , q = 25 cent

Nickel, n = 5 cent

3 times as many nickels as quarters;

n = 3q

Total value of coins = $12

n + q = $12

0.05n + 0.25q = 12

0.05(3q) + 0.25q = 12

0.15q + 0.25q = 12

0.40q = 12

q = 12 / 0.40

q = 30

n = 3q

n = 3(30)

n = 90

90 nickels

What is the slope of the line that passes through the points (4,9) and (1, 6)?​

3
----
3


m = 1

Answer:

The answer is 1

Step-by-step explanation:

to calculate the slope m use the

gradient formula

m = y2 - y1/x2 - x1

let (x1, y1) = (4, 9) and (x2, y2) = (1, 6)

⇒ m = 6 - 9/1 - 4 = -3/-3 = 1.

Answer:

$192

Hope this helped!

(Also pls make me brainliest im trying to level up)

Answer:

192$ (sale price)

Step-by-step explanation:

First we have to find 20% of 240

240×20/100         We multiply 240 by 20/100 because a percent is always  over 100 (as a fraction)

(240×20/100=48)     Now that we know 20% of 240 we have to subtract

240-48=192

192$ is the sale price

Hey! I'm confused on this question It's : 3/4 - 3/10​

Answers

Answer:

9/20

Step-by-step explanation:

I hope this helps :)

Answer:

9/20

Step-by-step explanation:

In order to subtract fractions you need to find the least common denominator.  Since the LCD is 20 (4 times 5 or 10 times 2) you need to multiply each fraction by 1 to get the denominators the same.

3/4 times 5/5 = 15/20

3/10 times 2/2 = 6/20

now you can subtract!

15/20 - 6/20 = 9/20

you can not simplify this, so your final answer is 9/20

Lines m and n are parallel. The measure of angle 6 is 55°.
What is the measure of angle 1?




35°


55°


125°


155°

Answers

Answer:155

Step-by-step explanation:

because they are parallel lines. If the angles differed even by 1°, eventually the lines would meet, therefore they would not be parallel.

Answer:

Firstly angle 6 and 2 are equal because of corresponding angles

so 6 = 2

Now angle 1 + 2 = 180 ( linear pair)

angle 1 = 180 - 55

1 = 125

answer - hey, if your looking for the answer to this question, i figured it out! You can put two identical trapezoids together to form a parallelogram with the same height as the trapezoid and a base length equal to the sum of the base lengths of the trapezoid. The area of the parallelogram is (b1 + b2)h, so the area of the trapezoid is one-half of this area. (let me know if this is correct of helpful)

What are the coordinates of point S"? (negative three-halves, nine-halves) (negative nine-halves, fifteen-halves) (nine-halves, negative three-halves) (negative fifteen-halves, 0)

Answers

Answer:

[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]

Step-by-step explanation:

The missing details are:

[tex]T= (0,4)[/tex]

[tex]M = (\frac{9}{4}, \frac{5}{4})[/tex] --- Midpoint of ST

Required

Determine the coordinates of S

To do this, we apply the mid-point formula:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

Where

[tex]M(x,y) = (\frac{9}{4}, \frac{5}{4})[/tex]

[tex]T(x_1,y_1) - (0,4)[/tex]

The equation becomes:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(0+x_2,4+y_2)[/tex]

[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(x_2,4+y_2)[/tex]

Multiply through by 2

[tex]2*(\frac{9}{4},\frac{5}{4}) = 2*\frac{1}{2}(x_2,4+y_2)[/tex]

[tex](\frac{9}{2},\frac{5}{2}) = (x_2,4+y_2)[/tex]

By comparison:

[tex]x_2 = \frac{9}{2}[/tex]

[tex]4 + y_2 =\frac{5}{2}[/tex]

[tex]y_2 =\frac{5}{2}-4[/tex]

[tex]y_2 =\frac{5-8}{2}[/tex]

[tex]y_2 =-\frac{3}{2}[/tex]

Hence, the coordinates of S is:

[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]
