Otrada [13]

The expression is equivalent to \rm2( \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\.

<h2 /><h2>Given that</h2>

Expression; \rm 2(\dfrac{3}{4}x+7) -3(\dfrac{1}{2}x-5)

<h3>We have to determine</h3>

Which expressions are equivalent to the given expression.

<h3>According to the question</h3>

Expression; \rm 2(\dfrac{3}{4}x+7) -3(\dfrac{1}{2}x-5)

To solve the given expression follow all the steps given below.

By applying the distributive property of multiplication;

\rm a(b+c) = ab+ac

Then,

The equivalent expression is,

\rm 2(\dfrac{3}{4}x+7) -3(\dfrac{1}{2}x-5)\\&#10;\\&#10;\rm (2 \times \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\&#10;\\&#10;2( \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\

Hence, the expression is equivalent to \rm2( \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\.

The Ratio of two numbers is 3/5, and their sum is 104. What are the 2 numbers?
Rom4ik [11]

Answer:

39 and 65

Step-by-step explanation:

the ratio of the two numbers is 3 : 5

sum the parts of the ratio, 3 + 5 = 8 parts

divide the sum by 8 to find the value of one part of the ratio

104 ÷ 8 = 13 ← value of 1 part of the ratio , then

3 parts = 3 × 13 = 39

5 parts = 5 × 13 = 65

the two numbers are 39 and 65
