Solve the system of inequalities: a) .4x−1≤0 2.3x≥4.6

Mathematics
1 answer:
OleMash [197]2 years ago
4 0

Answer:

(a) x \leq 2.5

(b) x \geq 2

Step-by-step explanation:

Solving (a):

0.4x - 1 \leq 0

Add 1 to both sides

0.4x - 1 + 1\leq 0 + 1

0.4x \leq 1

Solve for x

x \leq 1/0.4

x \leq 2.5

Solving (b):

2.3x \geq 4.6

Solve for x

x \geq 4.6/2.3

x \geq 2

Bogdan [553]

Answer:

145

Step-by-step explanation:

angles in a pentagon add up to equal 540

Hence, 110 + 90 + 80 + 115 + v = 540

( note that we just created an equation that we can use to solve for v )

We now solve for v using the equation created

110 + 90 + 80 + 115 + v = 540

step 1 combine like terms

110 + 90 + 80 + 115 = 395

we now have 395 + v = 540

step 2 subtract 395 from each side

540 - 395 = 145

395 - 395 cancels out

we're left with v = 145

Neko [114]

Answer:

The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.

Step-by-step explanation:

Given the survey, the prevalence of the flu, as a percentage, is given by:

Number of individuals diagnosed with flu, multiplied by 100, and divided by the size of the sample.

In this question, we have that:

Sample of 25,000, and 4,250 of those had been diagnosed with the flu at some point in the past year. So, the prevalence of the flu is given by:

\frac{4250*100}{25000} = 17

The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.
