two equal sides of triangle are 3cm more than three times the third side find the sides of the triangle if its perimeter is 21 CM​

Well they have to  be perpendicual because they cross and parallel means that they are like lines on lines paper, they do not cross, they just keep going. Hope this helps :)

Answer:

r= -4

Step-by-step explanation:

26+2=28

28/-7=-4

Answer:

x=6

Step-by-step explanation:

6(2x -11) 15 =21

6 × 2x = 12x

6 × -11 = -66

12x -66 + 15 = 21

-66 + 15 = -51

12x -51 = 21

-51 + 51 = 0

21 + 51 = 72

12x = 72

12x ÷ 2 = 0

72 ÷ 12 = 6

x = 6

Answer:

x = -2i, 2i

Answer:

x = 45

Step-by-step explanation:

15 = [tex]\frac{1}{3}[/tex] x ( multiply both sides by 3 to clear the fraction )

45 = x

Answer:

x = 45

Step-by-step explanation:

15 =  x

15(3)=x

45=x or x=45

Step-by-step explanation:

i tried 7 and it didn't work

so i used a hint - it's 6!

6 pies are more in 60 to 89 cherries than 90 to 119 cherries, a bar graph is a graphical depiction of information, amounts, or numbers using bars or strips.

They are employed to contrast and compare various data kinds, frequencies, or other measurements of several categories of data.

here, we have,

The calculation of the bar graph in the given question.

For 60 - 89 cherries there are 10 pies

For 90 -119 cherries there are 4 pies

10 -4 = 6  pies

The image for the graph is attached below.

When displaying sections of data, bar charts should be used. As long as there aren't too many categories to compare, vertical bar charts can be useful for comparing several categories or discrete data, such as age groups, classes, schools, etc. They are quite helpful for time series data as well.

Therefore, there are 6 more pies in the 60 -89 cherries category than in the 90-119 category.

Answer:

y = 3

Step-by-step explanation:

I hope this helps!

Answer:

y = 3

Step-by-step explanation:

6/2 equals 3, and since 2 times 3 equals 6, y is the answer for this problem.

Answer:

(-5,1)

Step-by-step explanation:

y= 13.5+2.5x

-13.5 -13.5

-13.5= 2.5x

x= -5.4

Answer:

  (c)  Store A, $0.50 cheaper

Step-by-step explanation:

When a price is discounted by a rate d, the multiplier of the price is (1 -d).

The discounted price is $50 × (1 -0.05) = $50×0.95 = $47.50

__

The discounted price is $60 × (1 -0.20) = $60×0.80 = $48.00

__

The price at Store A is less by ...

  $48.00 -47.50 = $0.50

shop = 5 ÷ 100 × 50 = 2.5

shop = 20 - 60 × 100 = 12

shop = $50 - 2.5 = $ 47.5

Shop = $60 - 12 = $48

= $48 .00 - $ 47.50 = $0.50

Answer:

61

Step-by-step explanation:

488 / 8 = 61

3 equal angles

so the triangle is equilateral => 3 equal sides

4x-10 = 3x+2

x = 12

or

4x-10 = 5x-22

-x = -12

x = 12

or

5x - 22 = 3x + 2

2x = 24

x = 12

x = 12

Answer:

The value of x = 12

Step-by-step explanation:

This is an equilateral triangle and the sides of an equilateral triangle are equal .

By putting the two sides of the triangle equal , we can find out the value of x

=> 4x - 10 = 3x +2

=> 4x - 3x = 2 + 10

=> x = 12

Answer:

y = (3/2)x+1

Step-by-step explanation:

Slope intercept form is y=mx+b where m represents the slope and b represents the y-intercept. As we can see on this graph, the line intersects the y axis at (0,1). Therefore, the y-intercept is 1. Now, we can choose another point to find the slope. I'll choose (2,4). To reach (2,4) from the y-intercept, we have to go up 3 units and right 2 units. Therefore, the slope is 3/2.

Our equation of the line is: y = (3/2)x+1

Write the equation that describes that function.

Answer:

y = (3/2)x+1

Step-by-step explanation:

i got it right

Answer: y=1.25x, which equation represents the situtation.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

Here, given that,

The price of broccoli is $1.25 per pound.

Let, y be the total cost in dollars of buying x pound of broccoli.

Hence, equation represents the situtation is y=1.25x.

Answer: 16

Step-by-step explanation:

Answer:

=> x = 2.4

Step-by-step explanation:

By using PGT

=> (5+x)² = 7²+x²

=> 5² +x² +2(5)(x) = 49+x²

=> 25 + x² + 10x = 49 +x²

=> 10x = 49-25

=> 10x = 24

=> x = 24/10

=> x = 2.4
