Answer:

20 yards of fabric

Step-by-step explanation:

you can find this answer more easily by timing 2 by 8 then timing 1/2 by 8 witch would be 16 and 4 then all you do is add 16 and 4 to get 20

Suppose f(x)= 4x/3+5 and g(x) = x/3 +1. solve for x when f(x)=g(x)

yuradex [85]

$\bf \begin{cases}
f(x)=\cfrac{4x}{3}+5\\\\
g(x)=\cfrac{x}{3}+1
\end{cases}\qquad f(x)=g(x)\implies \cfrac{4x}{3}+5=\cfrac{x}{3}+1$

solve for "x" then

What is the factored form of _________?

enyata [817]

Answer:

Step-by-step explanation:

The expression given is a difference of cubes and factors as

a³ - b³ = (a - b)(a² + ab + b²)

8 $x^{24}$ = (2 $x^{8}$ )³ ⇒ a = 2 $x^{8}$

27 $y^{6}$ = (3y²)³ ⇒ b = 3y²

Hence 2 factors are

(2 $x^{8}$ - 3y²) and

((2 $x^{8}$ )² + (2 $x^{8}$ × 3y²) + (3y²)²)

= (4 $x^{16}$ + 6 $x^{8}$ y² + 9 $y^{4}$ )

Hence the factored form of the expression is C

Which ratio is greater, 4:5 or 3:4?

Grace [21]

4:5
explanation-

Express the given ratios as fraction

4 : 5 = 4/5 and 2 : 3 =2/3

Now find the L.C.M (least common multiple) of 5 and 3

The L.C.M (least common multiple) of 5 and 3 is 15.

Making the denominator of each fraction equal to 15, we have

4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15

Clearly, 12 > 10

Now, 12/15 > 10/15

Therefore, 4 : 5 > 2 : 3.

Answer:

EK = 9

Step-by-step explanation:

x + 11 = -5 + 2x -5 + 2x

x+11 = -10 + 4x

11 = 3x - 10

3x = 21
