Answer:

y = 3x - 6

Step-by-step explanation:

given 9x - 3y = 18

isolate - 3y by subtracting 9x from both sides of the equation

- 3y = 18 - 9x ( divide all terms by - 3 )

y = $\frac{18}{-3}$ - $\frac{9x}{-3}$

= - 6 + 3x = 3x - 6

There are 280 pieces of fruit in a fruit salad. There are twice as many raspberries as blueberries, three times as many grapes a

dedylja [7]

Answer:

64 cherries

Step-by-step explanation:

Given that

There are 280 pieces of fruit in a fruit salad

There are twice as many raspberries as blueberries,

three times as many grapes as cherries,

and four times as many cherries as raspberries

We need to find out the number of cherries in the fruit salad

So,

Let us assume the blueberries be x

So, the raspberries be 2x

Cherries be 8x

And, grapes be 24x

Now

x + 2x + 24x + 8x = 280

35x = 280

x = 8

hence, the No of cherries in the salad

= 8 x

= 8(8)

= 64 cherries

If ∠G is supplementary to ∠H and the measure of ∠G is 65° what is the measure of ∠H?

Elina [12.6K]

Solution:

Given:

∠G = 65°

Supplementary angles are a pair of angles that sum up to 180°.

It should be noted:

If ∠G and ∠H are a pair of supplementary angles, they both sum up to 180°.

Equation formed: ∠G + ∠H = 180

Substitute the values into the equation.

∠G + ∠H = 180
=> 65 + ∠H = 180

Subtract 65 both sides.

=> 65 - 65 + ∠H = 180 - 65
=> ∠H = 180 - 65 = 115°

A loaded grocery cart is rolling across a parking lot in a strong wind. You apply a constant force F⃗ =( 35 N )i^−( 37 N )j^ to

Trava [24]

Answer:

-189.8 J

Step-by-step explanation:

We are given that f

Force applied=F=35 Ni-37 Nj

Displacement, s=(-8.7m)i-(3.1m)j

We have to find the work done .

We know that

Work done= $F\cdot s$

Using the formula

Work done= $(35i-37j)\cdot (-8.7-3.1)$

Work done= $-304.5+114.7$

Using $i\cdot i=j\cdot j=k\cdot k=1,i\cdot j=j\cdot i=j\cdot k=k\cdot j=i\cdot k=k\cdot i=0$

Work done=-189.8J

Hence, the work done =-189.8 J
