Answer:

C  multiply the first equation by 3

Step-by-step explanation:

3x-y =5

2x+3y = 10

We want to eliminate y

Since the first equation has a negative 1y  and the second equation has 3y

I would multiply the first equation by 3  and then the y's cancel

3(3x-y =5)

9x -3y = 15

2x+3y = 10

------------------

11x = 25

I don't understand what I should do for this ?I am very stuck.
Nana76 [90]
We can solve this by remembering that in each box, there are 10 grapefruit. This means we should multiply the number of boxes (20,400) by 10.

20400
*10
-----------
204,000

Using the calculation above, we know that 204,000 grapefruit were shipped.

one third of the sum of two angles is 60 degree and one quarter of their difference is 28 degree. find the two angles
vlabodo [156]
1/3(a + b) = 60
a + b = 60 * 3 = 180

1/4(a - b) = 28
a - b = 28 * 4 = 112

a + b = 180
a - b = 112
---------------add
2a = 292
a = 292/2
a = 146

a + b = 180
146 + b = 180
b = 180 - 146
b = 34

so ur 2 angles are : 146 and 34

Find the value of sin θ, if tan θ=4; 180° < θ <270°
Nana76 [90]
You can use the identity
\sin(x)=\sqrt{\dfrac{\tan(x)^{2}}{1+\tan(x)^{2}}}\\\\=-\sqrt{\dfrac{4^{2}}{1+4^{2}}}\\\\=-\sqrt{\dfrac{16\cdot 17}{17\cdot 17}}=\dfrac{-4\sqrt{17}}{17}

The sign is negative because the angle is in the 3rd quadrant.

This corresponds to ...
  a. -(4√17)/17

The volumes of two similar solids are 729 inches3 and 125 inches3. If the surface area of the smaller solid is 74.32 inches2, wh
tangare [24]
This is the concept of scales factors, given that two similar solids with 729 inches^3 and 125 inches^3. The volume scale factor will be given by:
(volume of larger solid)/(volume of smaller solid)
=729/125
but
linear scale factor=(volume scale factor)^1/3
thus the linear scale factor will be:
(729/125)^1/3
=9/5
Also, area scale factor will be given by:
area scale factor=(linear scale factor)^2
=(9/5)^2
=81/25
The area of the larger solid will be given by:
let the area be A;
A/74.32=81/25
thus
A=81/25*74.32
A=240.7968 inches^2
