Answer:

x = 40/9

Step-by-step explanation:

Since the angles are opposite angles they are equal. This means the equation to solve this would be:

9x + 15 =55

The Subtraction Property of Equality states that we can subtract the same amount from both sides of the equation and have an equivalent equation afterwards.

So subtract 15 from both sides to get:

9x = 40

The Division Property of Equality states that we can divide the equation on both sides of the equation and have an equivalent equation afterwards.

So divide both sides by 9 to get:

x = 40/9

A pineapple is 7 times as heavy as an orange. the pineapple also weighs 870 grams more than the orange. what is the total weight
san4es73 [151]
Let's translate each sentence into "Math".

Pineapple = p

Orange = x

is means equal

 

Pineapple is 7 times as heavy as an orange:  p = 7x

Pineapple weighs 870 grams more than orange. p = 870 + x

 

Substitute  p = 7x  into the second equation:

7x = 870 + x

Subtract  x from both sides

6x = 870

divide by 6

x = 145

 

The orange weighs 145 grams.

The pineapple weights 7 times the orange = 7(145) = 1015 grams.

Why is 2 + (-3) = -1
Softa [21]

Answer:

Because +- or - + = -

Step-by-step explanation:

-a + b = - c

a + - b = - c

-a × b = - c

a × - b = -c

Extra references:

-ve ×/+ -ve = +ve

+ve ×/+ -ve = - ve

-ve ×/+ +ve = - ve

+ve ×/+ +ve = +ve

Hope these could solve your problem.
