Step-by-step explanation:

this one is an easy relationship- if you have double the time (18 vs9), then you need half the workers (8/2)

Answer: 12 and -4

Step-by-step explanation:

Assume the larger number is x and the smaller one is y.

In that case the relevant simultaneous equations are:

x + y = 8

2x + 4y = 8

Use substitution to find relative value of y:

x + y = 8

y = 8 - x

Use to solve equation:

2x + 4y = 8

2x + 4(8 - x) = 8

2x + 32 - 4x = 8

2x  - 4x= 8 - 32

-2x = -24

x = -24 / -2

x = 12

y = 8 - x

= 8 - 12

= -4

Answer:

-5

Step-by-step explanation:

Each time the x value goes up 1, the y value goes down 5.

change in x = 1

change in y = -5

slope = (change in y)/(change in x)

slope = -5

Answer:

-five

Step-by-step explanation:

The origional question is ¨A turtle travels 1/2 mile in 1/9 hour. At this rate, how far can the turtle travel in an hour¨ To be honest i have no clue how to explain it but that is the awanser.

The turtle will travel  [tex]4\frac{1}{2}[/tex] in an hour.

A proportion is an equation in which two ratios are set equal to each other.

Given that, a turtle travels 1/2 mile in 1/9 hour. we need to find, at this rate, how far can the turtle travel in an hour.

We will solve this by using proportionality, since, rate is constant,

Let the turtle travels x miles in an hour,

Therefore,

x / 1 = (1/2) / (1/9)

x = 1/2 × 9

x = 9/2

x = [tex]4\frac{1}{2}[/tex]

Hence, the turtle will travel  [tex]4\frac{1}{2}[/tex] in an hour.

Answer:

Step-by-step explanation:

This is a cyclic quadrilateral.

It has a property of opposite angles being supplementary.

A and C are supplementary angles:

m∠A = 3x + 6 = 3*43+ 6 = 135°

Answer:

<A=135°

Step-by-step explanation:

3x+6+x+2=180

sum of two opposite angle of the cyclic quadrilateral is 180

4x=180-8

x=172/4=43°

<A=3×43+6=135° is your answer

The size of the angle 'x' is 117°

An external angle of a triangle is an angle formed by extending one side of the triangle and intersecting with the extension of another side.

In a triangle, the measure of an external angle is equal to the sum of the measures of the two opposite interior angles.

Here we have  a triangle

Let the ABC be the triangle as given in the picture

=> ∠A = 38°  

From the baseline BC

=> Measure of B = 180° - 101° = 79°

As we know

In a triangle, the measure of an external angle is equal to the sum of the two opposite interior angles

=> x = ∠A + ∠C

=> x = 38° + 79°

=> x = 117°  

Therefore,

The size of the angle 'x' is 117°

order of PEMDAS

simplify multiplication:

[tex] \displaystyle \: \sqrt{ {65}^{2} } [/tex]

use [tex]\sqrt{x^m}=x^{\frac{1}{2}\times m}[/tex] to simplify:

[tex] \displaystyle \: = {65}^{2 \times \frac{1}{2} } \\ = {65}^{ \cancel{ \: 2 }\times \frac{1}{ \cancel{ \: 2}} } \\ = {65}^{1} [/tex]

therefore our final answer is

Answer:

Step-by-step explanation:

Since the expressions are multiplied, for the product to equal zero, one term or another has to equal 0 because 0 times anything is zero.

(10-x)(3x-9)=0 when

10-x=0, x=10

3x-9=0, x=9/3=3

So there are two solutions when x=3 and x=10
