<u>Answer:</u>

The answer is c = \frac{d+ab}{a}

<u>Solution:</u>

When a sum of two numbers is multiplied by a number, the number can be distributed to the addends separately, then adding the products together will produce the same result as multiplying sum by the number. This property is called distributive property of multiplication.

To find the value of, a(c-b)=d

On applying the distributive property of multiplication which is [a\times(b+c)=a\times b+a\times c]

Here we get,

a\times(c-b)=a\times c-a\times b

So the equation will be,

a\times c-a\times b=d

ac-ab=d

ac=d+ab

c=\frac{d+ab}{a} or \frac{d}a+\frac{ab}{a}

Three of these fractions are equivalent: B. 12 C . 21 D. 74 30 A. . 70 Which one is the odd one out?
IrinaVladis [17]

Answer:

12/30

Step-by-step explanation:

Here is the complete question

Three of these fractions are equivalent A.30/70 B.12/30 C.9/21 D.6/14 which one is the odd one out

to determine the equivalent fractions, convert the fractions to percentage

\frac{30}{70} × 100 = 42.86%

\frac{12}{30} × 100 = 40%

\frac{9}{21} × 100 = 42.86%

\frac{6}{14} x 100 = 42.86%

Another method is to convert the fraction to its simplest form

30/70

To transform to the simplest form. divide both the numerator and the denominator by 10 = 3/7

12/30

To transform to the simplest form. divide both the numerator and the denominator by 6 = 2/5

9/21

To transform to the simplest form. divide both the numerator and the denominator by 3 = 3/7

6/14

To transform to the simplest form. divide both the numerator and the denominator by 2 = 3/7

Using either methods, 12/30 is the odd one out

A paint store sells exterior paint for $35.75 a gallon and paint rollers for $6.00 each. Write an equation in standard form for
VLD [36.1K]
The total price for the gallons of paint will be 35.75p

The total price for the rollers will be 6r

So the equation if the customer have 190 will be
price for gallons of paint + price for rollers = 190
35.75p + 6r = 190

How can finding the slopes of MN and AB help in proving that MN is the midsegment of triangle ABC?
Mademuasel [1]
Mid-segment and bottom side of the triangle is always parallel to each other, and parallel lines must have same slopes, so if their slopes are equal, then MN would be mid-segment of side AB in Triangle ABC

Hope this helps!

The Mean Corporation's statisticians would like to construct a hypothesis test for the mean annual profit (μ) earned by health-d
Jobisdone [24]

Missing Part of Question

Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700

........

Answer:

z = 1.157

Step-by-step explanation:

Given

Annual profit as calculated = $90,300.

H0: μ = 89,000

Ha: μ > 89,000

σ = 8700

n = 60

Calculate the test statistic (z) that corresponds to the sample and hypotheses.

Test statistic (z) is calculated by

z = (x - μ)/(σ/√n)

Where x = 90,300

μ = 89,000

σ = 8700

n = 60

z = (90,300 - 89,000)/(8700/√60)

z = 1.157443298866584

z = 1.157 ----- Approximated
