It would be 100. If you divide 100/10, you get 10, multiply that by 9 and you’d get 90.

What does x equal to x/7 - 4 = -5

beks73 [17]

Answer:

x = -7

Step-by-step explanation:

So we are asked to find what x is equal to in the equation:

$\frac{x}{7}-4=-5$

In other words, we are asked to solve for x.

$\frac{x}{7}-4=-5$

Add 4 to both sides of the equation.

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

Multiply both sides by 7.

x = -7

So we have solve the equation for x and have found that x = -7.

I hope you find my answer and explanation to be helpful. Happy studying.

Students in a school were asked to collect old bottles as part of a recycling drive. Some of the data recorded at the drive is s

Basile [38]

Answer:

The number of students who collected exactly 9 bottles.

Step-by-step explanation:

The given histogram shows the number of students who participated in the recyling drive & their old bottle waste collection.

We can find out the total number of students who participated just by looking at the histogram (students = 10), the number of students who colected bottles below 7 or 3 bottles etc.

But since the number of bottles is given in the form of grouped data, one cannot infer the exact number of bottles collected by students.

Hence, out of the given statements, 'The number of students who collected exactly 9 bottles' is the incorrect one.

The function f(x) is shown below.

JulsSmile [24]

Answer:

$f(g(2)) = 2$

Step-by-step explanation:

Given

$x \to f(x)$

$-6 \to 1$

$-3 \to 2$

$g(x) = f^{-1}(x)$ --- inverse

Required

$f(g(2))$

For two functions f(x) and g(x) where f(x) and g(x)are inverse;

$f(g(x)) = x$

So, by comparison:

$f(g(2)) = 2$

On Monday, jack and Jill walked from their house up the hill to get to the bus stop. They walked 4 yards every three seconds. Wr

never [62]

Answer: Our required equation will be

$3d=4t$

Step-by-step explanation:

Since we have given that

Jack and Jill walked 4 yards every three seconds

As we know that

$Speed=\frac{Distance}{Time}\\\\Speed=\frac{4}{3}\text{ yards per seconds}\\$

Now, we need to find the find the equation to represent the distance,d,

Jack and Jill walked over time t .

So here it is,

$Distance=Speed\times Time\\\\d=\frac{4}{3}\times t\\\\d=\frac{4}{3}t\\\\3d=4t$

Hence, our required equation will be

$3d=4t$
