Use the area of rectangle formula which is:

Given that:
- area of rectangle = 16
- width = 8
- length = x-5
Substitute in the formula:

Distribute 8 in the expression:

Move -40 to another side and change from -40 to 40.

Then move 8 to divide 56, leaving only x.

Hence, the answer is:

Just can decorate 2 full cakes. 6 divides by 3 is 2. So she decorated 2 per hour. If you do the work it’s 2 divided by 0.75 (3/4) you get 2 2/3. But that’s not a full 3 cakes so only 2. Glad to help!
Answer:
1.5
Step-by-step explanation:
k= y/x
y= 12-4.5 =7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
Answer:
<em>The man paid $200 for the cow</em>
Step-by-step explanation:
<u>System of Equations</u>
Let's call:
x = price of the cow
y = price of the horse
The man bought the cow and the horse for $500, thus
x + y = 500 [1]
The cow was sold at a profit of 10%, thus:
Sale price of the cow= 1.1x
The horse was sold at a loss of 10%, thus:
Sale price of the horse= 0.9y
The total operation was a 2% loss, i.e. 0.98*500=490. Thus, we have:
1.1x + 0.9y = 490 [2]
From [1]:
y = 500 - x
Substituting in [2]:
1.1x + 0.9(500 - x) = 490
Operating:
1.1x + 450 - 0.9x = 490
0.2x = 490 - 450 = 40
x = 40/0.2
x = 200
The man paid $200 for the cow
Answer:
9
Step-by-step explanation:
When plugging 6 in for y, you get
2x + 3(6) = 36
You have to multiply 3 and 6, getting
2x + 18 = 36.
Now, you subtract 18 from both sides to isolate the x variable, getting
2x = 18
Now, you divide 2 from both sides because we want x standing by itself, getting
x = 9
Therefore, your answer is 9.
Hope this helped
