Answer:

D: 5 : 8 and 20 : 32

Step-by-step explanation:

A is incorrect because 3 x 1.33 = 4 and 4 x 1.25 = 5.

B is incorrect because 10 x 1.6 = 16 and 12 x 1.5 = 18.

C is incorrect because 7 x 1.428 = 10 and 10 x 1.4 = 14.

D is correct because 5 x 4 = 20 and 8 x 4 = 32.

another way of solving the ratio answers is by putting them in a fraction 5/8 = .625 and also does 20/32 = .625.....

Easy right!?

crimeas [40]

Answer:

Faisal receives $241

Ahmed receives $482

Walid receives $723

Step-by-step explanation:

I am going to build a system of equations to solve this question.

We have that:

x is the amount that Faysal received.

y is the amount that Ahmed received.

z is the amount that Walid received.

Ahmed, Walid and Faisal made $1446 profit from selling used books.

This means that

$x + y + z = 1446$

Ahmed to receive double amount of Faisal

This means that $y = 2x$

Walid to receive triple amount of Faisal.

This means that $z = 3x$

$x + 2x + 3x = 1446$

$6x = 1446$

$x = \frac{1446}{6}$

$x = 241$

$y = 2x = 2*241 = 482$

$z = 3x = 3*241 = 723$

Faisal receives $241

Ahmed receives $482

Walid receives $723

How do you solve 3x-4=2x+1

kifflom [539]

Solution for 3x+4=2x-1 equation:

Simplifying

3x + 4 = 2x + -1

Reorder the terms:

4 + 3x = 2x + -1

Reorder the terms:

4 + 3x = -1 + 2x

Solving

4 + 3x = -1 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

4 + 3x + -2x = -1 + 2x + -2x

Combine like terms: 3x + -2x = 1x

4 + 1x = -1 + 2x + -2x

Combine like terms: 2x + -2x = 0

4 + 1x = -1 + 0

4 + 1x = -1

Add '-4' to each side of the equation.

4 + -4 + 1x = -1 + -4

Combine like terms: 4 + -4 = 0

0 + 1x = -1 + -4

1x = -1 + -4

Combine like terms: -1 + -4 = -5

1x = -5

Divide each side by '1'.

Your Answer is x = -5

Hope it helps!

the second angel im a triangle is 2° less the 3 times the first angle the third Angle is 14° more than twice the first angle fin

soldier1979 [14.2K]

Let's say the angles are "a", "b" and "c"

$\bf \begin{cases}
\stackrel{first}{a}\\
\stackrel{second}{b}=\stackrel{\textit{2 less than 3 times \underline{a}}}{3a-2}\\
\stackrel{third}{c}=\stackrel{\textit{14 more than twice \underline{a}}}{2a+14}
\end{cases}
\\\\\\
\textit{now, the sum of all internal angles in a triangle is }180^o
\\\\\\
a+b+c=\implies a+(3a-2)+(2a+14)=180
\\\\\\
6a+12=180\implies 6a=180-12\implies 6a=168\implies a=\cfrac{168}{6}
\\\\\\
a=28$

so a = 28°, plug that in "b" and "c", to see how much each is.
