Mathematics
1 answer:
horsena [70]3 years ago
6 0

Answer

y = (1/4)x - 5                 or     4y - x + 20 = 0

Explanation

To get the rule required, we interpret the sentence and write it in a mathematical form.

5 less than one fourth of x is y  

one fourth of x ⇒ (1/4)x

5 less than one fourth of x is y  ⇒  (1/4)x - 5 = y

y = (1/4)x - 5

4y = x - 20

4y - x + 20 = 0

If the area of the trapezoid below is 98 square units,what is the value of x?<br>Plz help!
aleksandrvk [35]
Area of Trapezoid is = 1/2 x height x (base1 + base2)

Here, Area = 98, base1 = 8, base2 = 20 and height = unknown (x)

So, 1/2 x height x (8+20) = 98
==> 1/2 x height x 28 = 98
==> height x 14 = 98 
==> height = 98/14 
==> height = 7 units

So, the final answer is --> the value of x = 7 units

Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the House blend
TiliK225 [7]

The ratio House blend/Organic Free Trade blend is the same and must remain the same.

So, the proportion is:

\frac{140}{168}=\frac{130}{x}

Where x is the unknown amount of the Organic Free Trade blend.

So, from the proportion, we have:

\begin{gathered} 140\cdot x=168\cdot130 \\ 140x=21840 \\ \frac{140x}{140}=\frac{21840}{140} \\ x=156 \end{gathered}

Answer: 156 pounds of Organic Free Trade blend

The first one is 3:6, or 1:2 in simplest form. There are three hammers for every six screw drivers.

The second one is 2:8, or 1:4. I am not sure if they want you to actually count each banana, but if so, that would be the answer. For every 2 apples, there are 8 bananas. If you are not supposed to count the bananas, it would be 2:2, or 1:1.

The third one is 15:100, or 3:20 in simplest form. For every 15 sixth grade teachers, there are 100 sixth grade students.

Hope this helps!!! :)))
