d=?
Convert
1min=60sec
2 min x 60 sec / 1min = 120 sec
d=vt
= 4m/s * 120s
= 480 m
Example:
The given terms here are: Distance = 150 km Time = 7200 s Speed =? To express the speed in appropriate units, in this given we can simply kilometer to meter which is the SI unit for distance. Hence, we do the conversion first. </span><span><span>

Answer:
(-6,-4)
Step-by-step explanation:
to get to -4 from 2 you have to subtract 6, making the slope x/6 but you said the slope is 3/2. divide 6 by 2 and you get 3. 3x3=9 making the slope 9/6. simplify and you get 3/2
<u>Given</u><u> info</u><u>:</u><u>-</u> In triangle (∆)ABC , in which ∠A = 2x, ∠B = x+15° and ∠C = 2x + 10°. Then find the value of x , also find the measure of each angles of a triangle.
<u>Explanation</u><u>:</u><u>-</u>
Let the angles be 2x, x+15 and 2x+10 respectively.
∵ Sum of the three angles of a triangle is 180°
∴ ∠A + ∠B + ∠C = 180° [Sum of ∠s of a ∆=180°]
→2x + x+15 + 2x+10 = 180°
→ 2x + x + 2x + 15 + 10 = 180°
→ 3x + 2x + 15 + 10 = 180°
→ 5x + 15 + 10 = 180°
→ 5x + 25 = 180°
→ 5x = 180°-25
→ 5x = 155°
→ x = 155°÷5 = 155/5 = 31.
Now, finding the measure of each angles of a ∆ABC by putting the original value of “x”.
∴ ∠A = 2x = 2(31) = 62°
∠B = x+15 = 31 + 15 = 46°
∠C = 2x + 10 = 2(31) + 10 = 62 + 10 = 72°.
Answer:
<u>The amount of money Lily had when she left the store, in terms of m, is 86 - 6m</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
m = Milk Lily purchased
2m = Fruit Lily purchased (twice that amount on fruit)
3m - 6 = Bread Lily purchased (6 dollars less than 3 times the amount spent on milk for bread)
Amount of money Lily entered = $ 80
2. How much money did Lily have when she left? Write your answer in terms of m.
Let's write the equation to find out the money left in terms of m, this way:
Money left = 80 - m - 2m - (3m - 6)
Money left = 80 - m - 2m - 3m + 6
Money left = 86 - 6m
<u>The amount of money Lily had when she left the store, in terms of m, is 86 - 6m</u>
