Answer:

Step-by-step explanation:

The first equation has to be the ratio of raisins to sunflower seeds. If r is raisins and p is sunflower seeds and there are 3 times as many raisins as sunflower seeds then the first equation must be 3r=p

The second equation should model the prices properly. Raisins are 1.5 per pound and sunflower seeds are 4 per pound, because of this we should have 1.5r (r being each pound of raisins) and 4p (p being each pound of sunflower seeds). From this we know the second equation must be 4p+1.5r=34

X - y= -4 -2x +3y =6

STatiana [176]

Answer:

x=-6, y=-2, (As a point) (-6, -2).....The point form is not necessary unless you want to solve the system (of equations) by graphing.

Step-by-step explanation:

By substitution:

x-y=-4 By adding y on both sides,

x=y-4

Now you can substitute x for the expression (y-4)

Plug the (y-4) as x in the other equation.

So -2x+3y=6 becomes

-2(y-4)+3y=6

Now solve:

-2(y-4)+3y=6 distributes out to be

-2y+8+3y=6 Now combining like terms

y+8=6 Subtract 8 on both sides to isolate the variable

y=-2

Now plug the value -2 in where the y is in any equation (preferably the easier/less complicated one) and solve for x.

So x-y=-4 becomes

x-(-2)=-4

=x+2=-4

=x=-6

Find the volume of the pyramid

podryga [215]

Answer:

88 $cm^{3}$

Step-by-step explanation:

Given 3 measurements 6,11,4

Assuming them to be length, width and height of pyramid

⇒

Length= 6 cm

Width= 11cm

Height= 4 cm

⇒

$\text{Volume of a Pyramid}= \frac{Length \times Width \times Height}{3}$

Therefore Volume of Given Pyramid

= $\frac{6\times 11\times 4}{3} =\frac{264}{3} =88$

⇒Volume of pyramid=88 $cm^{3}$
