Find the solution of this system of equations
-3x - 5y = -26
X - 5y = -38

Answer:

[tex]\sqrt{89}[/tex]

Step-by-step explanation:

distance = [tex]\sqrt{(x_{2}- x_{1})^{2} + { (y_{2} - y_{2} } ){^2} }[/tex]

Let:

(x₁ , y₁) = (0 , 5)

(x₂ , y₂) = (8 , 0)

Plug in the corresponding numbers to the corresponding variables:

Remember to follow PEMDAS. Solve the parenthesis first:

distance = [tex]\sqrt{(8- 0)^{2} + { (0 - 5 } ){^2} }[/tex]

distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]

Solve for the powers next:

distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]

distance = [tex]\sqrt{64 + 25}[/tex]

Simplify:

distance = [tex]\sqrt{64 + 25}[/tex]

distance = [tex]\sqrt{89}[/tex]

Answer:

not sure but I think it goes something like this

1. 10+10+10=30

2. 1+1+10=12

3. 1+1+3=5

4. 3•2+10=16

Step-by-step explanation:

why 3•2? because there is only one taco so 3 and there are two carrots (each carrot =1, each taco = 3) so 2.

Answer:

Slope = 1/2

Whole equation: y = 1/2x - 2

Step-by-step explanation:

Equation: y = mx + b

(3 , 4) and (0 , -2)

[tex]\frac{0 - 3}{-2 - 4} = \frac{-3}{-6} = \frac{1}{2}[/tex]

y = 1/2x + b

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

-2 = 1/2(0) + b

-2 = b

Step-by-step explanation:

Answer: 0.34

Step-by-step explanation:

From the question, 14 adults and 20 children attended a piano recital. This means that there are 14 + 20 = 34 people who attended the paint recital.

If two people are selected to receive door prizes at the recital, the probability of selecting the first child will be 20/34 while the second child will be 19/33. To get the probability of both being children, we have to multiply the fractions

= 20/34 × 19/33

= 380/1122

= 0.34

Answer:

The answer should be 22

Step-by-step explanation:

Using the circumference formula 2πr you can take half of the diameter to get the radius which is 3.5, then multiply 2x3.14 for π and take the product and multiply that by 3.5 to get 21.98, which rounds up

since volume is l x w x h, you have to divide 27 by 3. you can do this because it is a cube

Answer:

$3.32

Step-by-step explanation:

You take 30% of 4.75. You multiply 0.30 times 4.75. Then you subract that from 4.75. Boom.

Answer:

$3.33

Step-by-step explanation:

$4.75 by 30 then divide it by one hundred. So, the discount is equal to $1.43. To calculate the sales price, simply deduct the discount of $1.43 from the original price $4.75 then get $3.33 as the sales price.

Answer:

6 4/5

Step-by-step explanation:

-1 3/7 • (-3 2/5)

Let's turn them both into fractions with no whole numbers to make this easier:

-10/7 • -17/5

Now we can multiply straight across much easier!

170/35 (the negatives canceled each other out)

34/5 (simplified)

Answer:

B. Dan walked uphill, then downhill.

Step-by-step explanation:

The place that the slope went up is based on the distance from the starting point, so the distance is up then down. I hope this helped and please mark me as brainliest!

Answer:

Find a rectangular prism in your house exactly the same as this one,them you'll know the answer

Answer: 140 m3

Step-by-step explanation:

Multiply the area of the trapezoid face by the length .

Since the area is 20, you multiply it by 7 to get 140

Answer:

140 m^3

Step-by-step explanation:

This is a prism with a trapezoid base.

The volume if a prism is

V = (area of base) * height

The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.

area of trapezoid = (b1 + b2)h/2

In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.

V = (area of base) * (height of trapezoid)

V = (8 m + 2 m)(4 m)/2 * 7 m

V = 20 m^2 * 7 m^2

V = 140 m^3

i did the test

Answer:

For X they would have to divide the number from the first given chart for average household of the people that are ages 40 or under, which is 23, by the total internet, which is now 77.

Therefore, X = 23/77 = 0.2987, which would round to 0.30

Mark as brainliest please, I need a few more :)

Answer:

internet       54        23     77  

cable          81        92      173  

total            135       115     250

                 < 40      > 40    total

internet      w       x     1  

cable          y          z      1

total            .54       .46     1

x is 23 /77 =.29870

I’m just copying his answer which is 3

Step-by-step explanation:

at least I tried

Answer: 3

Step-by-step explanation:

37.5 (3.8-x) + 90x = 300

First, you have to simplify, by using the Distributive Property.

142.5 - 37.5x + 90x = 300

Now, add the like terms

142.5+ 52.5x = 300

Now, isolate the variable, meaning the variable has to be on one side on its own. You would have to subtract 142.5 and move it to the other side

52.5x = 300 - 142.5

52.5x = 157.5

Then, you divide!

[tex]\frac{52.5x}{52.5x}[/tex] = [tex]\frac{157.5}{52.5x}[/tex]

= 3

Answer:

16x and 2x have like terms

Answer: 28

Step-by-step explanation: Follwing PEMDAS, add the 3 and 5 in the parentheses first. You get 8, then multiply by 3, which gives you 24. Add 4 to 24 and it will give you 28.

Answer:

If i'm not mistaken, using PEMDAS which is parenheses, exponents, multiplication, division, adding and subtracting, the answer will be 28.

Step-by-step explanation:

3+5=8

8 * 3= 24

24 + 4= 28
