Step-by-step explanation:
you need to substitute the x in (7x +2y=13) with (x=2y+11) to solve it
area of rectangle : length x width
1) 7 x 5 = 35
area = 35 in^2
2) area of trapezoid : (a+b)h/2
area = 272 cm^2
3) area = 45.5 in^2
4) area of rhombus : base x height
area = 80 m^2
5) area = 108 cm^2
Hey friend,
the answer, you divide 4 2/7 by 2.
half of 4 is 2 and half of 2/7 is 1/7
so you get 2 1/7 of the daily recommended sugar.
Since both equations equal Y, set them equal to each other and solve.
3x -1 = -2x +9
Add 2x to each side:
5x - 1 = 9
Add 1 to each side:
5x = 10
Divide both sides by 5:
x = 10/5
x = 2
Now replace x with 2 and solve for y:
y = 3(2) -1 = 6-1 = 5
x = 2, y = 5 (2,5)
Answer:
Step-by-step explanation:
let V be the vector.
V=8i-6j
|V|=√(8²+(-6)²)=√(64+36)=√(100)=10
