Answer:

x = -8

Step-by-step explanation:

We have the expression 12 - 4x = 44 and are asked to find the value of x.

To solve this, we need to isolate x, or get it by itself.

12 - 4x = 44

Subtract 12 from both sides :

-4x = 32

Divide -4 from both sides :

x = -8

At Fruits R Us, Mr. Orchard realizes that dried pineapple slices and dried apricots were two of his top dried fruit sellers. So

Rudik [331]

Answer:

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=300 (1)

5x+8y=300*7

5x+8y=2100(2)

First, you can isolate x in (1):

x=300-y (3)

Now, you can replace (3) in (2):

5(300-y)+8y=2100

1500-5y+8y=2100

3y=2100-1500

y=600/3

y=200

Then, you can replace the value of y in (3) to find x:

x=300-200

x=100

According to this, the answer is that he should use 100 pounds of dried pineapple and 200 pounds of dried apricots.

Nadia is a stockbroker. She earns 4% commission when she sells stocks. Last week, she earned $288 in commission.

Tresset [83]

Answer:

a)The total amount of her weekly stock sales = $7,200

b) The total amount of her yearly stock sales = $350,000

Step-by-step explanation:

(a) Let us assume that the total a mount of her sales in a week = $m

Commission earned in a week = $288

Now, 4 % of her total sales = $288

or, 4% of ($m) = $288

⇒ $\frac{4}{100} \times m = 288$

or, $m = \frac{288 \times 100}{4} = 7,200$

⇒ m = $7,200

Hence, the total amount of her weekly stock sales = $7,200

b) Let us assume that the total amount of her sales in a year = $k

The total amount of commission earned = $14,000

Now, 4 % of her total sales = $14,000

or, 4% of ($k) = $14,000

⇒ $\frac{4}{100} \times k = 14,000$

or, $k = \frac{14,000 \times 100}{4} = 350,000$

⇒ k = $350,000

Hence, the total amount of her yearly stock sales = $350,000
