4. What percent of 20 is 5?​

Answer:x=4 y=3

Step-by-step explanation:

Let's solve your system by substitution.

2x−1=y+4;3y+1=3x−2

Step: Solve2x−1=y+4for y:

2x−1=y+4

2x−1+−y=y+4+−y(Add -y to both sides)

2x−y−1=4

2x−y−1+−2x=4+−2x(Add -2x to both sides)

−y−1=−2x+4

−y−1+1=−2x+4+1(Add 1 to both sides)

−y=−2x+5

−y

−1

=

−2x+5

−1

(Divide both sides by -1)

y=2x−5

Step: Substitute2x−5foryin3y+1=3x−2:

3y+1=3x−2

3(2x−5)+1=3x−2

6x−14=3x−2(Simplify both sides of the equation)

6x−14+−3x=3x−2+−3x(Add -3x to both sides)

3x−14=−2

3x−14+14=−2+14(Add 14 to both sides)

3x=12

3x

3

=

12

3

(Divide both sides by 3)

x=4

Step: Substitute4forxiny=2x−5:

y=2x−5

y=(2)(4)−5

y=3(Simplify both sides of the equation)

what level is this question?

Answer:

2.3cm

Step-by-step explanation:

We can see that it's a right triangle, similar to the one on the bottom left. Because the long side is 4 times longer, the short side is 4 times longer as well. So it's around

0.57cm*4= 2.28cm

Rounding to the 1st decimal place 2.3cm.

Please note, that rounding to 2 decimal places the answer 2.28cm could be inaccurate, e.g. if the real length would have been close to 0.574(9) or 0.565, but all of those options still round to 2.3cm.

Answer:

[tex]\Huge\boxed{x=15}[/tex]

Step-by-step explanation:

Hello There!

The angle labeled 6x is a right angle

If an angle is formed using the diameter of a circle then the opposite angle of that side is a right angle

So 6x = 90

isolate the variable

divide each side by 6

90/6= 15

6x/6=x

we're left with x = 15

Answer: 15

Step-by-step explanation:

Since the angle looks to be around 90 degrees and the x is timsed by 6 the answer would have to be a lower number. And from the options only 15 would work.

Answer:

82 mm^2

Step-by-step explanation:

you would have to find the area for 2 squares. The first is 8 x 9, so the area of that would be 72. The second square is 5 x 2, which is ten. Add those together to get 82

The answer is G

Step-by-step explanation:

Answer:

$16,800

Step-by-step explanation:

The amount that would be in the account = amount deposited + interest earned on deposit

interest earned on deposit can be determined by determining the simple interest

Simple interest = principal x time x interest rate

principal = the amount deposited = $15,000

Time = the duration of the deposit = 4 years

interest rate = the percentage on deposit that would be earned = 3%

15,000 x 0.03 x 4 = $1,800

The amount that would be in the account = $15,000 + $1800 = $16,800

Answer:

ΔABC and HGF are similar.

Step-by-step explanation:

In the given triangles ABC and HGF,

If both the triangles are similar,

Their corresponding sides will be proportional.

[tex]\frac{AB}{GH}=\frac{BC}{FG}= \frac{AB}{HF}[/tex]

[tex]\frac{72}{12}=\frac{48}{8}= \frac{84}{14}[/tex]

6 = 6 = 6

True.

Therefore, ΔABC and HGF are similar.

answer is x = 10 degrees

Step-by-step explanation:

a right angle is 90 degrees. the angles added are 4x + 3x + 2x = 90.

so 9x = 90

divide by 9 on both sides

x = 10

Answer:

4800 cubic Inches

Step-by-step explanation:

Wesley's laundry basket has a rectangular base with an area of 200 square inches. The basket has a height of 24 inches and it is full of clothes. What is the volume of Wesley's laundry basket?

The volume of Wesley's Rectangular laundry basket = Area of the Base × Height of the basket

Base area = 200 square inches

Height of the basket = 24 inches

Volume of the basket = 200 square inches × 24 inches

= 4800 cubic Inches

Answer:

45

Step-by-step explanation:

To know how many 1/5 s are in 9, we will take the ratio of both numbers as shown;

9:1/5

= 9 ÷ 1/5

= 9 * 5/1

= 9 * 5

= 45

Hence there are 45 1/5s in 9

Answer:

She made $1230 more on printed shirts than plain shirts in 25 weeks.

Step-by-step explanation:

Hi,

Okay, I have to admit, this is pretty complicated. But, it's not impossible :) First things first, we know that the equation in the table is the number of shirts sold after W number of weeks. We know that we need to, first, find the total number of shirts sold in 25 weeks.

The equation for the plain shirts is 5w -4. Let's start with that.

Plugin 25 for w to find the total number of plain shirts sold after 25 weeks.

5w - 4

5(25) - 4

= 121

She sold 121 plain shirts after 25 weeks. But we're not done yet, we still have to see how much money she made after selling 121 plain shirts. To do this, we have to multiply the total number of plains shirts sold by 15. (we know that each plain short costs $15, that's why we're multiplying it by 121)

When you do this...

121 x 15

You get...

$1815

She got $1815 after 25 weeks just for selling plain shirts.

Now, let's find the total cost of printed shirts after 25 weeks.

The equation for the printed shirts if 8w + 3.

8w + 3

8(25) + 3

= 203

She sold 203 printed shirts in 25 weeks. Let's find the cost. Each printed shirt costs $15 so we need to multiply 203 by 15.

203 x 15

You get...

$3045

She made $3045 by selling printed shirts in 25 weeks.

Now, we have to subtract $3045 by $1815 to find how much more she made. You get...

3045 - 1815

= $1230

She made $1230 more on printed shirts than plain shirts in 25 weeks.

I really hope this helps :)

[tex] \huge \boxed{ \boxed{ 50 \sqrt{3} \: or \: 86.6}}[/tex]

Step-by-step explanation:

to find the height we need to use tan function because we are given adjacent and angle and we need to figure out opposite (height) [tex]\tan(\theta)=\dfrac{opposite}{adjacent}[/tex]

let opposite be AC

let adjacent be BC

according to the question:

[tex] \quad \: \tan( {60}^{ \circ} ) = \dfrac{AC}{BC} [/tex]

now we need a little bit algebra to figure out AC (height)
