Hi there:)
Total ratio
2+3+7=12
Now find the weight of sand in each bag

Small bag
90×(2÷12)
=15 kg
Medium bag
90×(3÷12)
=22.5
Large bag
90×(7÷12)
=52.5

Hope it helps

Solve the following system of equations by graphing. Then determine whether the system is consistent or inconsistent and whether

Olenka [21]

Recall that the slope-intercept form of the equations of a line is:

$y=mx+b\text{.}$

Taking both equations to their slope-intercept form we get:

$\begin{gathered} 6x+6y-6x=-30-6x, \\ 6y=-30-6x, \\ \frac{6y}{6}=-\frac{30}{6}-\frac{6}{6}x, \\ y=-x-5\text{.} \end{gathered}$ $\begin{gathered} 3x+3y-3x=-15-3x, \\ 3y=-15-3x, \\ \frac{3y}{3}=-\frac{15}{3}-\frac{3}{3}x, \\ y=-x-5. \end{gathered}$

Notice that both equations are the same, therefore the system has infinitely many solutions, therefore it is consistent and dependent.

Answer:

Equations:

$\begin{gathered} y=(-1)x+(-5), \\ y=(-1)x+(-5)\text{.} \end{gathered}$

The system is consistent and dependent.

A solution to the system is (0,-5).

What is the equation of the line that passes through the point (-2,7) and has a slope of zero

Yanka [14]

Answer:

y = 0

Step-by-step explanation:

y - y₁ = m(x - x₁)

y - (7) = 0(x - (-2))

y - 7 = 0(x + 2)

y - 7 = 0

y = 7

Please help me on this I am stuck and I need help ASAP

k0ka [10]

Answer:

Grace is right

Step-by-step explanation:

3(2-x)-2(6x-8)=

so:

3×2 is 6

3×(-x) is -3x

-2×6x is -12x

-2×(-8) is 16 because -×- equals +

3(2-x)-2(6x-8)

=6-3x-12x+16

= -15x+22
