Jamal planted 53 fewer flowers than Heidi. Write an expression to show how many flowers Heidi planted.

Sergeu [11.5K]

Answer:

y = x + 53

Step-by-step explanation:

Let x be the number of flowers Jamal planted and y the number of flowers Heidi planted.

Jamal planted 53 fewer flowers than Heidi:

x = y - 53

Isolate the y.

x + 53 = y (Change the - sign to + sign when switching from different sides of an equation)

y = x + 53

The lengths of two sides of a triangle are given.

azamat

Answer:

Range = 5 - 29

Step-by-step explanation:

a + b > c

a+c > b

c+b > a

so

17+ 12 > c ,,,,,,,,,,,,,,,,,,,,,,,,,,,, so it should be lesser than 17+12 which is 29

17 +c > 12 ,,,,,,,,,,,,,,,,,,,,,,,,, and it should be greater than 17- 12 = 5

c+12 > 17 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, same here, it should be greater than 17- 12 = 5

So the range is ,

17 + 12

to

17-12

whcih is - (5 to 29)

I hope I am right!!!

Create a number pattern that follows the rule

vazorg [7]

Answer:

The pattern form is 8,15,34,71 which follows the rule $x^3+7$

Step-by-step explanation:

Given : Rule $x^3+7$

To find : Create a number pattern that follows the rule. Use at least three terms in the pattern ?

Solution :

Rule $x^3+7$

Put n=1,

$x^3+7=(1)^3+7$

$x^3+7=1+7=8$

Put n=2,

$x^3+7=(2)^3+7$

$x^3+7=8+7=15$

Put n=3,

$x^3+7=(3)^3+7$

$x^3+7=27+7=34$

Put n=4,

$x^3+7=(4)^3+7$

$x^3+7=64+7=71$

The pattern form is 8,15,34,71 which follows the rule $x^3+7$
