3 a plus b equals 54, when b equals 9?

Mathematics
1 answer:
Tema [17]3 years ago
6 0

Answer:

a = 15 when b = 9

Step-by-step explanation:

3 a plus b equals 54  in symbolic terms is 3a + b = 54.

Now, if b = 9, 3a + b = 54 becomes 3a + 9 = 54.

Subtracting 9 from both sides yields an equation for 3a:

3a = 45

Dividing both sides by 3 yields a = 15 when b = 9

One way to test if a graph is a function or not is by doing a?
KATRIN_1 [288]

One way to test if a graph is a function or not is by doing a <u>vertical line test</u>.

<em>The </em><u><em>vertical line test</em></u><em> is tested by testing if any vertical line is drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function, if there isn't any such line, the graph is a function.</em>

Hope that helps!

Find the number if 1 2/3% of it is 4.75
Alecsey [184]
<h2>Answer:</h2>

The number is:

                      285

<h2>Step-by-step explanation:</h2>

It is given that:

1 2/3% of a number is 4.75.

Let the number be x.

We know that:

1\dfrac{2}{3}=\dfrac{1\times 3+2}{3}=\dfrac{5}{3}

This means that:

\dfrac{5}{3}\%\ of\ x=4.75

i.e.

\dfrac{5}{3\times 100}\times x=4.75\\\\\dfrac{1}{60}\times x=4.75\\\\x=4.75\times 60\\\\x=285

Hence, the number is: 285
