Answer: 6 years old.

Step-by-step explanation:

For this exercise let "x" represents your present age.

According to the information provided in the exercise, you know that In three years, Chad will be three times your present age.

Then, your age in three years can be represented with the following expression:

$x+3$

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

$x+3=\frac{3x}{2}$

Therefore, the final step is to solve for "x" in order to find its value.

You get that this is:

$2(x+3)=3x\\\\2x+6=3x\\\\6=3x-2x\\\\x=6$

Can you help with this please?

Answer:

Step-by-step explanation:

the answer is A. if you notice the y-intercept, it its at -5

A is the only answer choice that gives -5 as the y-intercept

another way to make sure that A is the right answer is to calculate the slope

when you increase 3 units UP (y), you increase 5 units to the RIGHT (x)

since slope is y/x, it should be 3/5 which is also in A

another way to check A is to plug in points

hope this helps!

HELP ASAP, DUE AT 11:59<br><br> g(-5)=

Dovator [93]

Answer:

g(-5) = -6

Step-by-step explanation:

We need to find value of g(-5)

Looking at the graph in figure when g = -5, the value on the graph is -6 as it is highlighted with blue point.

because we have x = -5 so, we will look at graph that passes through x and y when x= -5, so we get y=-6

So, g(-5) = -6

a storage room measures 20 feet by 15 feet. the floor is covered by tiles that cost $7.50 per square foot. what will be the cost

Sidana [21]

Answer: $2250

Step-by-step explanation:

<u>Given information</u>

Dimension of the room = 20 feet × 15 feet

Cost of tiles = $7.50 / ft²

<u>Derived formula from the given information</u>

Total cost = Floor area × Cost of tiles

<u>Substitute values into the formula</u>

Total cost = Floor area × Cost of tiles

Total cost = (20 × 15) × (7.5)

<u>Simplify by multiplication</u>

Total cost = 300 × (7.5)

$\Large\boxed{Total~cost~=~2250~Dollars}$

Hope this helps!! :)

Given log Subscript 3 Baseline 2 almost-equals 0. 631 and log Subscript 3 Baseline 7 almost-equals 1. 771, what is log Subscript

kari74 [83]

You can use the properties of logarithm to get to the solution.

The approximate value for given term is given by

$log_3(14) \approx 2.402$

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

$a^b = c$

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

$b = log_a(c)$

Some properties of logarithm are:

$log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})$

<h3>Using the above properties</h3>

$log_3(2) + log_3(7) = log_3(2 \times 7) = log_3(14)\\\\0.631 + 1.771 = log_3(14)\\\\log_3(14) = 2.402$

Thus,

The approximate value for given term is given by

$log_3(14) \approx 2.402$

Sam and Bethan share £54 in the ratio 5:4 how much dose each get

Agata [3.3K]

Ratio 5:4
Total shares = 5+4 = 9

then to find for 1 share = 54/9 = 6

So Sam share = 6 x 5 = 30
Bethan share = 6 x 4 = 24

Poof: 30+24 = 54
