Answer:
x = -5
Step-by-step explanation:
Start by adding the 5x to each side of the equation to the left to get...
-25 = 5x + 25 + 5x
Then you would add 25 to each side of the equation to get...
0 = 10x + 25 + 25
Adding on, you would simplify this step to get...
0 = 10x +50
You would now have to make the x variable on one side alone so you would subtract 50 from both sides of the equation again to get...
-50 = 10x
Finally you would divide both sides of the equation by 10 to get x alone...
-50/10 = 10x/10
And simplify that to get...
x = -5
Answer:
a negative times a negative is a positive so 8×3=24/19 will give you that answer
you add -2 to the other side with 25 and get 27 then u work the rest of the problem out to solve for x
Weight of an grapefruit=weight of an orange+8% weight of an orange
weight of an apple=weight of an orange -10% weight of an orange
a.<span>By what percentage is the grapefruit heavier than the apple?
We should find the connection between grapefruit and an apple. We know the connection between the weight of a grapefruit and an orange, we know the connection between an orange and an apple, so this means we know the connection between a grapefruit and an apple.
</span>
weight of an grapefruit=weight of an <span>orange+8% weight of an orange
</span>weight of an orange=weight of an apple<span> +10% weight of an apple
</span>
-> weight of an grapefruit=weight of an apple+10% weight of an apple + 8%(weight of an apple+10% weight of an apple)= weight of an apple + 18% weight of an apple + 2% weight of an apple= <span>weight of an apple + 20% weight of an apple
</span><span>b.By what percentage is the apple lighter than the grapefruit?
</span>weight of an grapefruit=weight of an apple + 20% weight of an apple<span>
</span>
-> The apple ts 20% lighter than the grapefruit.
