Marni writes this system to determine how much of each ingredient Alyssa plans to buy. She uses x to represent

liubo4ka [24]

Answer:

Alyssa buys 4 cups of frozen fruit puree and 2 cups of yogurt.

Step-by-step explanation:

Here, x = Represent cups of frozen fruit puree

y = Represent cups of yogurt.

The given system of equations by Marni are:

x + y = 6,

2x + 3y = 14

After first step of elimination,the equations are:

-2x - 2y = -12

2x + 3y = 14

Now, ADD BOTH THE EQUATIONS to eliminate the variable x:

-2x - 2y + (2x + 3y) = -12 + 14

or, y = 2

Now, put y =2 in x + y =6, we get

x = 6 - y = 6 -2 = 4

So, x = 4 and y = 2 is the solution of the given system.

Hence, Alyssa buys 4 cups of frozen fruit puree and She buys 2 cups of yogurt.

Arte-miy333 [17]

Answer:

14x+3=8x+3

14x+3 -3 = 8x+3 -3

Cancels out the 3

14x = 8x

14x - 8x = 8x -8x

Cancels out the 8x

14x = 0

x = 0

Nadia is a stockbroker. She earns 11% commission each week. Last week, she sold $7,000 worth of stocks. How much did she make

makvit [3.9K]

Answer:

Nadia's commission per week is $770

Amount Nadia made in commission in 2011 is $40,040

Step-by-step explanation:

Commission made last week = 11% of $7,000

Therefore commission made last week = 0.11 × $7,000 = $770

Whereby Nadia averages the same aount each week, the amount Nadia would make in commission in 2011 is given by

Amount Nadia makes per week in commission = $7,000

Number of weeks in a year = 52 weeks. Therefore, amount Nadia makes in one year is given by

Amount in commission per week × 52 weeks

=$770 × 52 = $40,040

Amount Nadia made in 2011 = $40,040.

I need answers please l don’t understand please show working to help me please

Ira Lisetskai [31]

Answer:

1)

$10t=8+9t+5$

$10t=9t+13$

$10t-9t=13$

$t=13$

2)

$-12=3x$

$-4=x$

$x=-4$

3)

$-5+3x=x+9$

$3x=x+9+5$

$3x=x+14$

$3x-x=14$

$2x=14$

$\frac{2x}{2}=\frac{14}{2}$

$x=7$

4)

$10a=-15+7a$

$10a-7a=-15$

$3a=-15$

$\frac{3a}{3}=\frac{-15}{3}$

$a=-5$

5)

$7x=6x+27$

$7x-6x=x$

$x=27$

6)

$-3x-6=-5x+10$

$-3x=-5x+16$

$-3x+5x=16$

$2x=16$

$\frac{2x}{2}=\frac{16}{2}$

$x=8$

7)

$2y-4=10y+12$

$-4=8y+12$

$-4-12=8y$

$-16=8y$

$\frac{8y}{8}=\frac{-16}{8}$

$y=-2$

8)

$-9a+1=6-4a$

$1=6+5a$

$1-6=5a$

$-5=5a$

$\frac{5a}{5}=\frac{-5}{5}$

$a=-1$

Hope this helps!
