Answer:
x = 3
Step-by-step explanation:
5x - 2 = 13 (write the equation)
5x - 2 + 2 = 13 + 2 (isolate the variable)
5x = 15
5x/5 = 15/5 (simplify)
x = 3
Answer: x=3
Step-by-step explanation:
13=5x-2
13+2=5x
15=5x
x=15/5
x=3

Answer:

Step-by-step explanation:
Alex, Susan and Amy shared 66 watermelons. The number of watermelons owned by Alex is two times the number of watermelons owned by Susan, while Amy has 6 more than Susan. Find the ratio of the number of watermelons owned by Susan to the number of watermelons owned by amy.
Answer:
5:7
Step-by-step explanation:
First you have to find the watermelons owned by the three of them.
Let's take Susan as 'x'
According to the question:
1. Alex has twice the watermelons as Susan -> 2x
2. Amy has 6 more watermelons than Susan -> x+6
The sum of the watermelons is 66
SO,
x + 2x + x + 6 = 66
4x = 60
x = 15
Susan has 15
Alex has 30
and Amy has 21
Now we do the ratio:
Susan : Amy
15 : 21
5 : 7

This diagram shows part of a regular 10 sided polygon.
Work out the size of angle marked x.
Answer:
144 degrees
Step-by-step explanation:
work out the exterior angle of the shape 360/no of sides
then take it away from 180 (angle on a straight line) leaving you with the answer
The required measure of x would be 144 degrees for the shown figure.
What is the interior Angle?An interior angle is defined as an angle produced on the inside of a polygon by extending the sides of the polygon.
Interior angles of a polygon = (sides - 2) × 180°
This diagram shows part of a regular 10-sided polygon.
As per the question,
10x = (10- 2) × 180°
10x = 8 × 180°
10x = 1,440°
x = 1,440°/10
Apply the division operation, and we get
x = 144°
Thus, the required measure of x would be 144 degrees.

On the southeast corner of millennium park,there is a garden walk.it is marked off in red in the drawing below. Side C,the hypotenuse of the triangle,show the row along which flowers will be planted. If a side measures 90 feet and side b measures 120 feet how many feet of flowers will be planted along side C, the hypotenuse of the triangle? Show your work and explain your reasoning.
Answer:
150 ft
Step-by-step explanation:
Apply pythagorean theorem to find length of hypotenuse, side c:
Pythagorean theorem is given as:
c² = a² + b²
a = 90 ft
b = 120 ft
c = hypotenuse
Plug in the values
c² = 90² + 120²
c² = 22,500
Take the square root of both sides
c = √22,500
c = 150 ft

Anna, Boris, and Clara thought of one number each. Anna's number increased by 20 is 21 greater than Boris's numbers decreased by 22. Boris's number decreased by 20 is 21 greater than Clara's number increased by 22. How much less is Clara's number than anna's number. Please answer fast!
Answer:
See below in bold.
Step-by-step explanation:
Let Anna's, Boris and Clara's numbers be a b and c.
a + 20 = b - 22 + 21
b - 20 = c + 22 + 21
a + 20 = b - 1
b - 20 = c + 43
a - b + 20 = -1
Adding the last 2 equations:
a = c + 42
c = a - 42
So Clara's number is 42 less then Anna's number.

The isosceles triangle shown has a base of 4 y + 2 and a perimeter of 6 y + 12 . Which expression represents the length of 1 of the triangle's legs?
Answer:
The expression that represents the length of 1 of the triangle's legs is y + 5
Step-by-step explanation:
An isosceles triangle has two sides equal which are the triangle legs. Let b represent the base of the triangle and l represent one of the triangle's legs. Then, the perimeter, P is given by
P = l + l + b
i.e P = 2l + b
From the question, P = 6y + 12 and b = 4y +2
∴ 6y + 12 = 2l + 4y + 2
6y - 4y + 12 - 2 = 2l
2y + 10 = 2l
∴ 2l = 2y + 10
Then,
l = (2y+10)/2
l = y + 5
Hence, the expression that represents the length of 1 of the triangle's legs is y + 5

Answer:
[tex]\frac{1}{6}[/tex]

What is the measure of \angle 1?, What is the measure of \angle 2?, What is the measure of \angle 4? and What is the measure of \angle 5?
Answer:
<1 and <6 = 98
<2 and <3 = 139
<4 and <5 = 123
Step-by-step explanation:
82 + 9x - 6 + 6x - 1 = 180
15x + 75 = 180
15x = 105
x = 7
<1:
x + 82 = 180
x = 98
<2:
6x - 1 = 6(7) - 1 = 41
x + 41 = 180
x = 139
<3 = <2 because of vertical angle thm so <3 = 139
<5:
9x - 6 = 9(7) - 6 = 57
x + 57 = 180
x = 123
<4 = 5 because of vertical angle thm
<6 = <1 because of vertical angle thm
Daphne played 240 consecutive games of soccer without being taken off the field. Then, after a single game on the sidelines, she played another string of consecutive games, although this string was 40% shorter. How many consecutive games was that?
Answer:
144.
Step-by-step explanation:
40% shorter means she played 100 - 40 = 60% of the previous tall.
60% of 240
= 240 * 0.6
= 144 games.
