1.x+4y- - 67 =-1
x+4y+67=-1
x+4y=-1-67
X+4y=-68

2.2x-y+2z=-7
2x=-7+y-2z
x=-7/2+1/2y-z
x=-7/2+1/2y-z, y€R, z€R

Warning: I don’t have the € and R

3.-x+2y- -43=5
-x+2y+43=5
-x+2y=5-43
-x+2y=-38
x-2y=38

Hope this helps!

The magnitude of vector a = (5,m) is 13 and the magnitude of vector b = (n, 24) is 25. What are m and n
Ulleksa [173]

Answer:

m=12\,,n=7

Step-by-step explanation:

The magnitude of vector (x,y) is given by \sqrt{x^2+y^2}

The magnitude of vector a=(5,m) is 13.

\sqrt{5^2+m^2}=13\\5^2+m^2=13^2\\25+m^2=169\\m^2=169-25\\m^2=144\\m=12

The magnitude of vector b=(n,24) is 25.

\sqrt{n^2+24^2}=25\\n^2+24^2=25^2\\n^2+576=625\\n^2=625-576\\n^2=49\\n=7

Therefore,

m=12\,,n=7

toby needs 2 4/5 poundscof clay to make one sculpture how many sculptures can he make from 14 pounds of clay show your work
nikklg [1K]
He can make 5 sculptures.

We divide the amount of clay, 14 pounds, by the amount it takes to make one sculpture, 2 4/5 pounds:

14 ÷ 2/45 = 14 ÷ 14/5 = 14/1 ÷14/5 = 14/1 × 5/14 = 70/14 = 5
