Step-by-step explanation:

2(k-5)+3k=k+6

step 1 distribute the 2 to whats in the parenthesis

2k-10+3k=k+6

step 2 combine any like terms if there are any

5k-10=k+6

step 3 add 10 to each side

5k=k+16

step 4 subtract 1k from each side

4k=16

step 5 divide each side by 4

k=4

A local charity sponsors a 5K race to raise money. It receives $25 per race entry and $5,000 in donations, but it must spend $5

kenny6666 [7]

they receive 25 per entry but 5 goes towards the cost of the race

so 25-5 = 20 per entry is for the charity

so 20x + 5000 = 25000

subtract 5000 from each side

20x= 20000

divide both sides by 20

x = 20000/ 20

x = 1000

they need at least 1000 entries to make 25000

so to make more than 25000, they need 1001 entries

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

Step-by-step explanation:

Step 1: Define

Point (2, -20)

Point (1, -20)

Step 2: Find slope m

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

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-20+20}{1-2}$
[Fraction] Subtract/Add: $\displaystyle m=\frac{0}{-1}$
[Fraction] Divide: $\displaystyle m=0$
