A student solved this problem by working backward. Jared has some flowers. He has 6 more red flowers than yellow flowers. He has

twice as many orange flowers as red flowers. He has 4 yellow flowers. How many flowers does Jared have altogether? Student's solution: Jared has 4 yellow flowers. He has 6 more red than yellow flowers (4 + 6 = 10). He has twice as many orange flowers as red flowers (10 × 2 = 20). So Jared has 4 + 10 + 20 = 34 flowers. Use a similar strategy to solve this problem. Kathleen has some balloons. She has 7 more silver balloons than gold balloons. She has 3 times as many bronze balloons as silver balloons. She has 5 gold balloons. How many balloons does Kathleen have altogether?

Students in an environmental science class raised money to buy plants for a community garden. The students raised money by selli
finlep [7]

Answer:

50 gluten-free cupcakes and 100 regular cupcakes.

Step-by-step explanation:

Let's define the variables:

R = number of regular cupcakes sold

G = number of gluten-free cupcakes sold

The total amount of money raised then is:

M = R*$2.00 + G*$3.00

We also know that:

The number of regular cupcakes sold was 2 times the number of gluten-free cupcakes sold.

then:

R = 2*G

And we also know that the amount of money raised is $350

Then we have the equations:

R = 2*G

R*$2.00 + G*$3.00 = $350

We can replace the first equation into the second one, so we have only one variable:

(2*G)*$2.00 + G*$3.00 = $350

Now we can solve this for G.

G*$4.00 + G*$3.00 = $350

G*$7.00 = $350

G = $350/$7.00 = 50

G = 50

50 gluten-free cupcakes where sold.

And using the equation:

R = 2*G = 2*50 = 100

We can conclude that 100 regular cupcakes were sold.

Genrish500 [490]

Answer:

Step-by-step explanation:

((8 x 10) x 3) + ((9 x 8)/2) x2 = (80 x 3) + (72/2) x 2
                                             = 240 + (36 x 2)
                                             = 240 + 72
                                             = 312

Y<2x+2 find the slope
Vesna [10]

<em>The slope is 2x.</em>

<em>X represents the slope.</em>

<em>Y represents the total cost or value</em>

<em>The +2 represents the Y-intercept.</em>

<em>I know this all for a fact because the equation is written out in the slope-intercept form which is commonly displayed like this:</em>

<em>Y = MX + B</em>

<em>Hope this helps and have a nice day.</em>
