Mary's and bob's ages combined are twice Jane's age Mary is 8 years older than Bob Jane's age plus Bob's age is 20 years how old are they?
(1) M+B=2*J (2) M=8+B (3) J+B=20 Three equations. Three unknowns. Rewrite (1) M=2*J-B Sub into (2) 2*J-B=8+B Solve for B 2B+8=2J or B+4=J Sub J into (3) 2B + 4 = 20 B = 8 J = 12 M=16
Algorithm of the addition of the two matrix?
Matrix-Addition(a,b)1 for i =1 to rows [a]2 for j =1 to columns[a]3 Input a[i,j];4 Input b[i,j];5 C[i, j] = A[i, j] + B[i, j];6 Display C[i,j];
What is a plus b and a - b and c given a - b plus c equals 0 given vector a equals 4.0 i - 3.0 j plus 1.0 k and vector b equals -1.0 i plus 1.0 j plus 4.0 k?
a = 4.0 i - 3.0 j + 1.0 k b = -1.0 i + 1.0 j + 4.0 k → a + b = (4.0 + -1.0) i + (-3.0 + 1.0) j + (1.0 + 4.0) k = 3.0 i - 2.0 j + 5.0 k → a - b = (4.0 - -1.0) i + (-3.0 - 1.0) j + (1.0 - 4.0) k = 5.0 i - 4.0 j - 3.0 k → a - b + c = 0 → c = -(a - b) = -5.0 i + 4.0 j + 3.0 k So that a - b + c = (5.0 - 5.0) i + (-4.0 + 4.0) j + (-3.0 + 3.0) k = 0 i + 0 j + 0 k = 0.
