Answer:
c= -2.5-0.5d
Step-by-step explanation:
15=-3(2c+d)
15=-6c+-3d
15+3d=-6c
-2.5-0.5d=c
Answer:
m∠MON = 15°
Step-by-step explanation:
The given parameters are;
m∠LON = 77°
m∠LOM = 9·x + 44°
m∠MON = 6·x + 3°
By angle addition postulate, we have;
m∠LON = m∠LOM + m∠MON
Therefore, by substituting the known values, we have;
∴ 77° = 9·x + 44° + 6·x + 3°
77° = 9·x + 44° + 6·x + 3° = 15·x + 47°
77° = 15·x + 47°
77° - 47° = 15·x
15·x = 77° - 47° = 30°
15·x = 30°
x = 30°/15 = 2°
x = 2°
Given that m∠MON = 6·x + 3° and x = 2°, we have;
m∠MON = 6 × 2° + 3° = 12° + 3° = 15°
m∠MON = 15°.
Answer:
Hello your question lacks the required options here are the options
By blocking on stopping distance
By blocking on tire tread type
By blocking on automobile type
By blocking on automobile size
Without blocking
Answer : By blocking on automobile size
Step-by-step explanation:
The experiment can best be conducted by blocking on the automobile and this is because the Automobile size and the stopping distance are proportionally related (associated ) as seen from the previous experiments hence the best experiment is By blocking on the size of the automobile is very crucial .
we can have a symmetric tread tire or an asymmetric tires fixed on the different types of Automobiles simultaneously and see if the stopping distance will be affected when we change the tires that way we are blocking on the Automobile size the same type of tires will be fixed at the same time on each automobile size
The solution to given system of equation is (x, y) = (0.8, 2.2)
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
y + x = 3 --------- eqn 1
y = 1.5x + 1 ---------- eqn 2
We have to solve the above system of equations by substitution method
<em><u>Substitute eqn 2 in eqn 1</u></em>
1.5x + 1 + x = 3
Combine the like terms
2.5x + 1 = 3
Move the constants to Right hand side of equation
2.5x = 3 - 1
2.5x = 2
x = 0.8
<em><u>Substitute x = 0.8 in eqn 2</u></em>
y = 1.5(0.8) + 1
y = 1.2 + 1
y = 2.2
Thus the solution to given system of equation is (x, y) = (0.8, 2.2)
The correct answer is 21.5
