Answer:
7x-y=-3
Step-by-step explanation:
Answer:
This is an isoceles meaning pq ~ rq
so 2x+43 = 3x+37, so x equals 6
2(6)+43 = 55, so this means that angle p and angle r are both 55, which is 110
a triangle has a total of 180 degrees, leaving angle q to be equal to 70 degrees

Answer:
0.2 meters
Step-by-step explanation:
MA = Fᵇ / Fₐ = a/ b
Whereby;
MA = Mechanical Advantage
Fᵇ = Force b
Fₐ = Force a
a = distance a
b = distance b
Therefore mechanical advantage in the question can be calculated as;
MA = a/b
0.5 = a/ 0.4
a = 0.5 * 0.4
a = 0.2
First, write both the equations in its standard form.
Now, write the equations in form of matrix.
Then, multiply the equation towards the left by using the inverse of matrix
The product of the matrix & its inverse will be the identity matrix.
Now, multiply the matrices that lie on the left-hand side of the equal sign.
For the 2 × 2 matrix , the inverse matrix is ⇨ .
Do the calculations.
Multiply the matrices.
Do the arithmetics again.
Finally, extract the matrix elements x & y & write them separately.
