Answer:
D) 6(4 1/2 m + 2/3)=629Step-by-step explanation:
A display has 6 packs of marbles with a total mass of 629g. The packaging of each pack has a mass of 2/3 g and each marble has a mass of 4 1/2 g.
Which equation can we use to determine m, the number of marbles per pack?
A 6*4 1/2 m+ 2/3=629 B 6 m(4 1/2+ 2/3)=629 C 6 m+4 1/2+ 2/3=629 D 6(4 1/2 m + 2/3)=629================================
A total mass is the sum of 6 packs and each pack is:
m marbles + packaging = 4 1/2 m + 2/3We can put it as equation:
6(4 1/2m + 2/3) = 629Correct option is D
Answer:
D. 6(4 1/2 m + 2/3)=629

What is the answer to -12 = 4(f-6)
Answer:
Step-by-step explanation:
-12 = 4(-6 + f)
-12 = (-6 * 4 + f * 4)
-12 = (-24 + 4f)
-12 = -24 + 4f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-4f' to each side of the equation.
-12 + -4f = -24 + 4f + -4f
Combine like terms: 4f + -4f = 0
-12 + -4f = -24 + 0
-12 + -4f = -24
Add '12' to each side of the equation.
-12 + 12 + -4f = -24 + 12
Combine like terms: -12 + 12 = 0
0 + -4f = -24 + 12
-4f = -24 + 12
Combine like terms: -24 + 12 = -12
-4f = -12
Divide each side by '-4'.
f = 3
Simplifying
f = 3
Hope helps you

which expression represnts the product of 2xy and 3xy+5y-xy^2
Answer:
You distribute the 2xy and get
2xy(3xy + 5y - xy^2) = 6(x^2)(y^2) + 10xy^2 - 2(x^2)(y^3)
3(x + 1) + 2(x + 5)
Whats the answer to this
Let's simplify step-by-step.
3(x+1)+2(x+5)
Distribute:
=(3)(x)+(3)(1)+(2)(x)+(2)(5)
=3x+3+2x+10
Combine Like Terms:
=3x+3+2x+10
=(3x+2x)+(3+10)
=5x+13

Solve the quadratic equation 3x^2+x-5=0
Give your answers to 2 decimal places.
Answer:
x= 1.13 or x= -1.45
Step-by-step explanation:
use the quadratic square root formula (-b±√(b²-4ac))/(2a) .
a= 3
b=1
c= -5
replace the variables with the numbers listed above and just work out.
x= 1.13 or x= -1.45
Answer:
x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61
Step-by-step explanation:
3x^2+x-5=0
Using quadratic formula a=3, b=1, c=-5
x = -b ± √b^2 - 4ac / 2a
x = -(1) ± √(1)^2 - 4(3)(-5) / 2(3)
x = -1 ± √61 / 6
x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61

Step-by-step explanation:
There a is parallel to d because a is perpendicular to c and c is parallel to d which is the correct answer that would be option (C).
What is the coplanar?A group of points that are coplanar, or a planar surface that extends endlessly in all directions, are all located on the same plane. Four or more points may or may not be coplanar, however, any two or three points are always coplanar.
The distinct lines a, b, c, and d are in the same plane.
a⊥b, bllc, and clld
Line a is perpendicular to line b, line b is parallel to line c, and Line c is parallel to line d which is given in the question.
Line a is perpendicular to line b (given)
Line b is parallel to line c (given)
Line c is parallel to line d (given)
Thus, Line a is parallel to line d
Therefore, a is parallel to d because a is perpendicular to c and c is parallel to d.
Hence, the correct answer would be an option (C).
