Answer:

b. 0

Step-by-step explanation:

We have been given an equation $5x-8(x+5)=6-3x$ . We are asked to find the number of solutions for our given equation.

Let us solve our given equation. Using distributive property $a(b+c)=ab+ac$ , we will get:

$5x-8*x-8*5=6-3x$

$5x-8x-40=6-3x$

$-3x-40=6-3x$

Adding 3x on both sides of our equation, we will get:

$-3x+3x-40=6-3x+3x$

$-40=6$

Since both sides of our given equation are not equal, therefore, our given equation has no solution and option 'b' is the correct choice.

Zina [86]

Answer:

Step-by-step explanation:

No of students study math = 3/5 of 50 = 30

No of students study English = 3/10 of 50 = 15

Total = 30 + 15 = 45

Remaining students = 5

No of students study geography = 5

Fraction of geography to whole class = 5/45 = 9

Find the value of x so that the function has the given value.

nataly862011 [7]

For h(x) = -7x + 10, x =1

For r(x) = 4/5x+ 7 , x = -15

Step-by-step explanation:

in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values

So,

h(x) = -7x + 10; h(x) = 3

$h(x) = -7x+10\\3 = -7x+10\\3-10 = -7x+10-10\\-7 = -7x$

Dividing both sides by -7

$\frac{-7x}{-7} = \frac{-7}{-7}\\x = 1$

r(x) = 4/5x+7; r(x) = -5

$r(x) = \frac{4}{5}x +7\\-5 = \frac{4}{5}x +7\\-5-7 = \frac{4}{5}x\\-12 = \frac{4}{5}x\\x = -12 * \frac{5}{4}\\x = -15$
