y=x+5
y=-2x-4
solve by substitution

Answers

Answer 1

Answer:

x = − 3

Step-by-step explanation:

Let's solve your equation step-by-step.

− 2x − 4 = x + 5

Step 1: Subtract x from both sides.

− 2x − 4 − x = x + 5 − x

− 3x − 4 = 5

Step 2: Add 4 to both sides.

− 3x − 4 + 4 = 5 + 4

−3x = 9

Step 3: Divide both sides by -3.

−3x  / −3  =  9  / −3

x = − 3

A countertop is 11 feet long and 4 fee t wide.

What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place

Answers

Answer:

4.09m^2

Step-by-step explanation:

A countertop is 11 feet long and 4 fee t wide.

Using the conversion

1foot = 0.305 meter

11fet = 11(0.305)

11feet = 3.355 m

4 feet= 4 * 0.305

4feet = 1.22m

Area of the countertop = Length * Width

Area of the countertop = 3.355 * 1.22

Area of the countertop = 4.0931m^2

Hence the required area is 4.09m^2 to 2 decimal places

Coach Wu has a total of 30 soccer balls. 9 soccer balls are white the remaining soccer balls are one of three different colors (blue, pink, or green) there is an equal number of blue, pink, and green balls. How many green soccer balls does Coach Wu have?

Answers

Answer:

Number of green soccer balls = 7

Step-by-step explanation:

Total number of soccer balls = 30

Number of white balls = 9

Number of soccer balls excluding number of white balls = 30 - 9 = 21

Also, the remaining soccer balls are one of three different colors (blue, pink, or green) such that there is an equal number of blue, pink, and green balls.

Number of blue balls = Number of pink balls = Number of green balls = [tex]\frac{21}{3}=7[/tex]

Therefore,

Number of green soccer balls = 7

Answers

Answer: Yes these triangles are similar

Step-by-step explanation:

First lets write down what we know just to make life easier

x=9

TL should be similar to CH

LY should be similar to KH

The angles should be equal due to SAS

So the first thing we know is true is the fact that they have equal angles. Now we have to find out if the sides are similar or if they change by the same ratio to the other. If TL is similar to CH and TL=25  and CH=10 what is the change in size or dilation. Division should do the trick so 25/10=2.5 so TY is greater than CH by a factor of 10. Which means that LY should also be greater than KH by a factor of 2.5. If we are told that x=9 than side LY or 4(9)-1=35 and KH 9+5=14

So side KH is 14 and LY is 35. Now to check if they are similar then KH should be greater by a factor of 2.5. If this is not true than the sides are not similar.  35/2.5=14

Since 35 divided by 2.5 is 14 we can tell both sides TL and LY are greater than KH and CH by a factor of 2.5

Hope this helps.

find the length of a missing side of the triangle around your nearest tenth​

Answers

Using the Pythagorean theorem:

14^2 = 8^2 + x^2

196 = 64 + x^2

Subtract 64 from both sides:

132 = x^2

Take the square root of both sides:

X = 11.49

Rounded to nearest tenth = 11.5

Answer:

missing side = 11.5

Step-by-step explanation:

[tex]a^{2} = c^{2} - b^{2}[/tex]

[tex]a^{2} = 14^{2} - 8^{2}[/tex]

[tex]a^{2} = 196 - 64[/tex]

[tex]a^{2} = 132[/tex]

[tex]\sqrt{a^{2} } - \sqrt{132}[/tex]

a = 11.489

round to the nearest tenth:

11.489 = 11.5
