Answer:
Given the system of equation:
g +h = 9 ......[1]
8g + 7.5h = 71 ......[2]
We can write equation [1] as;
g = 9-h ......[3]
Now, substitute equation [3] in [2] we get;
Using distributive property i,e 
.
72 - 8h +7.5h = 71
Combine like terms:
72 - 0.5 h = 71
Subtract 72 to both sides of an equation:
72 - 0.5 h -72 = 71-72
Simplify:
- 0.5 h = -1
Divide both sides by -0.5 we get;
Simplify:
h = 2
Substitute the value of h =2 in equation [3] to solve for g;
g = 9 - 2 = 7
g = 7
Therefore, the solution for the given equation is :
g = 7 and h = 2
1 is the answer because it is
Answer:
9:34 pm
Step-by-step explanation:
First:
8:17 am
Go back 12 hours
8:17 pm
Round to 8:20
(keep the 3) Minus 43-17=26(3 is in this)
Therefore, 9:34 pm
Sorry if this doesn't make sense, it's hard to explain haha
Answer:
Step-by-step explanation:
- The length of the segment JM is 25 units.
- The segment JL is between 0 and 12, so is 12 units.
- The segment KL is between 5 and 12, so is 7 units.
<u>The probabilities for each point:</u>
- P(point on JL) = 12/25
- P(point not on KL) = 1 - 7/25 = 18/25
<u>Required probability:</u>
- P = 12/25*18/25 = 216/625
Correct choice is D
Irfan must walk a distance of <u>25</u> blocks <u>east</u> to return to his apartment building.
<h3>What is a compass?</h3>
A compass can be defined as a scientific instrument that contains a magnetized pointer, which is used to show and indicate the following four (4) main cardinal directions:
<h3>What is distance?</h3>
Distance can be defined as the amount of ground covered (traveled) by a physical object over a specific period of time and speed, regardless of its direction, starting point or ending point.
Next, we would calculate the total distance covered (traveled) by Irfan as follows:
Total distance = 20 + 5
Total distance = 25 blocks.
Since Irfan walked a total distance of 25 blocks west, he would have to walk the same distance in the opposite direction (east) to return to his apartment building.
