Answer:

Step-by-step explanation:

y = -2/3 x multiply both sides the first equation by 6

6y = -4x Add 4x to both sides.

6y + 4x = 0

-9y +4x = - 40 Subtract the bottom equation

15y = - 40 Divide by 15

y = -40/15

y = - 2.7

======================

6y = -4x

6*(-2.67) = -4x

-16 = - 4x

x = - 16/-4

x = 4

A man is 32 years old and his son is 5 years old. How many years hence will the

ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

the current ages:

father= 32 yrs old

son=5 yrs old

-------

4(5+x) = 32+x

20+4x = 32+x

4x-x = 32–20

3x =12

x = 12/3

x = 4 years

------------------------------------

after the 4 years later the farther age will be 36 ( 32+4 = 36)

the son will be 9 ( 5+4= 9 years)

the x presents how the father will be after 4 times the age of the son

When is it useful to guess check to solve mathematical problems?

Ad libitum [116K]

Answer:

often one of the first strategies that students learn when solving problems. This is a flexible strategy that is often used as a starting point when solving a problem, and can be used as a safety net, when no other strategy is immediately obvious.

Two vertical poles of lengths 11 ft and 14 ft stand 16 ft apart. A cable reaches from the top of one pole to some point on the g

Alex17521 [72]

We are given

total length of cable is 30 feet

and this cable is on hypotenuse sides of the triangles

so, we can draw triangle as

Let's assume those hypotenuse as 'a' and 'b'

so, we will have

$a+b=30$

now, we can find 'a' and 'b' from triangle

Smaller triangle:

$a=\sqrt{x^2+11^2}$

Larger triangle:

$b=\sqrt{(16-x)^2+14^2}$

we know that

$a+b=30$

so, we can plug this value

and we get

$\sqrt{x^2+11^2}+\sqrt{(16-x)^2+14^2} =30$

now, we can solve for x

$\left(\sqrt{x^2+11^2}\right)^2=\left(30-\sqrt{\left(16-x\right)^2+14^2}\right)^2$

$32x-1231=-60\sqrt{x^2-32x+452}$

$1024x^2-78784x+1515361=3600x^2-115200x+1627200$

now, we can use quadratic formula

we get

$x=\frac{-\sqrt{36416^2-1152389056}+36416}{5152},\:x=\frac{\sqrt{36416^2-1152389056}+36416}{5152}$

$x=4.510,x=9.627$

so,

The point should be located 4.510 feet , 9.627 feet from the smaller pole to use 30 feet cable............Answer

Meredith lives 24 blocks from her friends house if she travels on block every minute how many minutes will it take her to reach

Anestetic [448]

Meredinth takes 24 minutes to reach her friend house

Solution:

Given that, Meredith lives 24 blocks from her friends house

She travels one block every minute

To find: time taken by Meredith to reach friend house

From given,

Number of blocks between Meredith house and her friedn house = 24

She travels one block every minute

Thus she takes 1 minute for 1 block

One block = 1 minute

So, for 24 blocks, we have to multiply by 24

$24\ block = 1 \times 24\ minute\\\\24\ block = 24\ minute$

Thus Meredinth takes 24 minutes to reach her friend house
