Represent 24 as a sum of two numbers, first number from first die and second number from second die.
24=19+5=18+6=17+7=16+8=14+10=13+11=12+12=11+13=10+14=9+15=8+16=7+17=6+18=5+19=4+20 (the sums 15+9 and 20+4 are absent, because there aren't numbers: 20 on the first die and number 9 on the second die). Totally, you receive 15 different representations of 24.

(here
means that you have 20 possibilities to roll first number or blank face on the first die and 20 possibilities to roll number or blank face on the second die).

Answer:
y-4=-3/4(x+14)
Step-by-step explanation:
y-y1=m(x-x1)
m=-3/4
y-4=-3/4(x-(-14))
y-4=-3/4(x+14)
Answer:
it is 5/5, or if that doesn't work its 1 just in case you need to simplify
Step-by-step explanation:
from the first point, count how many squares go up, the count how many squares to the right, so up 5 over 5
Answer:
One pipe drains 140 L/min and the other pipe drains 190 L/min
Step-by-step explanation:
Assume that the pipe which releases less is x L/min
∵ One pipe releases x L/min
∵ Other pipe releases 50 L/min more than it
∴ The other pipe releases x + 50 L/min
∵ Water is being drained out of a tank through these 2 pipes
∵ Water is being drained at rate 330 L/min through them
- Add their rates and equate the sum by 330
∴ x + x + 50 = 330
- Add the like terms in the left hand side
∴ 2x + 50 = 330
- Subtract 50 from both sides
∴ 2x = 280
- Divide both sides by 2
∴ x = 140
∵ x represents the rate of one pipe and x + 50 represents the
rate of the other pipe
∴ One pipe drains 140 L/m
∴ Other pipe drains 140 + 50 = 190 L/min
Answer:
x=10
Step-by-step explanation:
5x - 6 = 44
(add 6 to 44)
5x=50
(divide 5 into 50)
x=10
