Answer:

7 more pennies.

Step-by-step explanation:

Quarters are .25 each and you have 2 so that is .50.

Dimes are .10 each and you have 12 so that is 1.20

Pennies are .01 each and you have 23 so that is .23.

Added together and you get 1.93. So all you need is 7 pennies to get 2 dollars.

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (4, -2)

Point (-1, 8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{8+2}{-1-4}$
[Fraction] Add/Subtract: $\displaystyle m=\frac{10}{-5}$
[Fraction] Divide: $\displaystyle m=-2$

Answer this question correctly please and then I’ll mark you as a brainliest!

Answer:

Step-by-step explanation:

1) 2 - (- 8) = 2 + 8 = 10

2) 2/5 + (- 1/5) = 2/5 - 1/5 = 1/5

3) We can find the common denominators through the least common multiple between the denominators:

4,12 | 2

2, 6 | 2

1, 3 | 3

1, 1 (2 × 2 × 3 = 12)

Then, 12 is the least common denominator.

4) 8 (1/4) + 10 (2/5) + 7 (5/8)

8 (1/4) = 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 1/4 = 33/4

10 (2/5) = 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 2/5 = 52/5

7 (5/8) = 8/8 + 8/8 + 8/8 + 8/8 + 8/8

+ 8/8 + 8/8 + 5/8 = 61/8

33/4 + 52/5 + 61/8

Employing the least common denominator:

4, 5, 8 | 2

2, 5, 4 | 2

1, 5, 2 | 2

1, 5, 1 | 5

1, 1, 1 (2 × 2 × 2 × 5 = 40)

(40 ÷ 4 × 33)/40 + (40 ÷ 5 × 52)/40 + (40 ÷ 8 × 61)/40

330/40 + 416/40 + 305/40

1051/40
