Find the value of x.5x50dA. 40B. 8ОО OC. 10D. 26
bekas [8.4K]

Given:

The sum of two angles 5x and 50 degrees equals 90 degrees.

To find: The value of x

Explanation:

Since the sum of two given angles equals 90 degrees.

So, we can write it as,

5x+50=90

Solving for x we get,

\begin{gathered} 5x=90-50 \\ 5x=40 \\ x=\frac{40}{5} \\ x=8 \end{gathered}

Thus, the value of x is 8.

Final answer: The value of x is 8.

lianna [129]
F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300

f(120) = (20 * 120) + 300 = 2400 + 300 = 2700

inna [77]

Answer:

B. Pie chart.

Step-by-step explanation:

In this question, the students are asked what political party they belong. The best display format would be one in which the graph can be divided into parts, or percents, according to the percentage of students belonging to each political party. The graph that best describes this, distributing a group into parts, is a pie chart, and thus, the correct answer is given by option b.

Scatterplot is used when two variables correlate together, that is, there is a relationship between them, which we don't have between the number, or proportion of students belonging to each political party. Stemplot are used when there is a high number of quantitative data, which we do not have here.
