Answer:

1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.

2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

Which pairs are like terms in expression 2/5y + 1/5x - 0.2y - 6 + (-2)
Gelneren [198K]

<em><u>The pair of like terms are:</u></em>

\frac{2}{5}y \text{ and } -0.2y

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

\frac{2}{5}y + \frac{1}{5}x -0.2y-6+(-2)

We have to find the pairs that are like terms in the given expression

Like terms means that, terms that have same varibale but different ( or same ) coefficients

Here in the given expression "x" and "y" are the two variables present

Arrange the like terms

\frac{2}{5}y-0.2y+\frac{1}{5}x-6+(-2)

So here the first two terms has same varibale "y" but different coefficients. So they form a pair of like terms

"x" is present only once . There is no other term with variable "x"

6 and -2 are constants

So the pair of like terms are: \frac{2}{5}y \text{ and } -0.2y

Evaluate the following expressions for a = -3,b=2,c=5
Ksju [112]

Hey!

----------------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), and (d = -4).

----------------------------------------------------------------------

Solution #1:

=\frac{a-4b}{3c+2d}

=\frac{(-3) - 4(2)}{3(5) + 2(-4)}

=\frac{(-3) - 8}{15 +( -8)}

=\frac{-11}{7}

≈ 1.57

----------------------------------------------------------------------

Solution #2:

= a - 4b / 3c + 2d

= (-3) - 4(2) / 3(5) + 2(-4)

= (-3) - 8 / 15 + (-8)

= (-3) - 0.53 + (-8)

= (-3.53) + (-8)

= -11.53

----------------------------------------------------------------------

Solution #1 Answer: 1.57

Solution #2 Answer: -11.53

----------------------------------------------------------------------

Hope This Helped. Good Luck! Brainly is here to help :)

7 2\3+ (5 1\6-1 5\9)
lorasvet [3.4K]
Start off with: 5 1/6 - 1 5/9
turn it into an entire fraction: 31/6 - 14/9
make a common denominator (which is 18): 93/18 - 28/18 = 93 - 28 = 65/18
65/18 + 7 2/3 is the new equation
7 2/3 = 23/3
23/3 = 138/18
65/18 + 138/18 = 203/18
Simplify: 203/18 = 11 5/18
Answer: 11 5/18
