5a - 7 = 0.1a - 0.14

DIA [1.3K]

Answer: a=1.4

Step-by-step explanation:

move the 0.1a to the other and the 7 to the other side which will make the 7 positive and the 0.1a negative.

5a-0.1= 4.9a

-0.14+7=6.86

dive both sides by 4.9 and you get

a=1.4

-(-6x - 5) = 4(5x + 3)

Lina20 [59]

Answer:

$\large\boxed{B)\ -\dfrac{1}{2}}$

Step-by-step explanation:

$-(-6x-5)=4(5x+3)\qquad\text{use the distributive property}\\\\-(-6x)-(-5)=(4)(5x)+(4)(3)\\\\6x+5=20x+12\qquad\text{subtrac 5 from both sides}\\\\6x=20x+7\qquad\text{subtract 20x from both sides}\\\\-14x=7\qquad\text{divide both sides by (-14)}\\\\x=-\dfrac{7}{14}\\\\x=-\dfrac{1}{2}$

F(x) = -x² + 7x - 12<br> One factor of this is (x - 4). Find the other factor.

saveliy_v [14]

Answer:

(3-x) is the other factor.

Step-by-step explanation:

The given function is :

$F(x)=-x^{2}+7x-12$

One of the factor is (x-4)

We need to find the other factor.

It can be solved as follows :

$F(x)=-x^{2}+4x+3x-12\\\\=(-x+3)(x-4)$

So, the other factor is (3-x).

Susan made $117 for hours 9 of work.

Irina18 [472]

First we need to figure out how much Susan made per hour

117/9 = 13 dollars per hour

Then find out how much she makes in 7 hours

13 • 7 = 91 dollars

$91 in 7 hours
