Answer:
D. (r + s)t = rt + st
Step-by-step explanation:
Distribute means that the term outside gets multiplied to each term on the inside of the parentheses
(r + s)t = rt + st
Answer:
J. 12 : 18
Step-by-step explanation:
Amy used 2 tea bags for every 3 cups of water to make iced tea
the ratio here is 2:3
x = 2:3
lets simplify our ratios
6 : 10 = 3 : 5 ≠ 2 : 3
5 : 6 = (doesn't simplify evenly) ≠ 2 : 3
9 : 15 = 3 : 5 ≠ 2 : 3
12 : 18 = 2 : 3 = 2 : 3
<h3>
Simplifying</h3>
find their highest common factor and divide both the numbers by the <u>same amount</u> (HCF).
Ex.
12 : 18
12 ÷ 6 = 2
18 ÷ 6 = 3
2 : 3
C.
Y=mx + b is the formula (M being slope, and B being the y intercept) always start by going up or down by what the y-intercept number is, if it’s -9 you go down the y axis 9 numbers from the origin (0,0) and slope (m) is always better put in a fraction-5x is better put in -5/1x
Think of the top number of the fraction as ‘up/down’ and the bottom number as ‘over’ if the top number is negative you will go down from the y-intercept number that many times, the bottom number is how many spots you go over from that number , it is always to the right.
Step-by-step explanation:
In the first part, he was travelling with twice the speed, or Vs, for distance
48 - d, for 2 hours.
speed = distance/time
distance = speed * time
First part :
48 - d = 2V * 2
⇒d + 4V = 48
Second part:
d = V * 2
⇒d = 2V
Substitute 2s for d in equation 1.
2s + 4s = 48
6s = 48
s = 8
The speed in the second part is 8 mph.
<u>The speed in the first part is 2s = 2(8) = 16</u>
