the sum of twice a number and 13 is 75
Answers
"The sum of twice a number and 13 is 75."...
Let's translate this into an equation:
[tex]2x+13=75[/tex]
Solve for x:
Add -13 to both sides.
[tex](2x+13)+(-13)=(75)+(-13)[/tex]
Simplify.
[tex]2x=62[/tex]
Divide both sides by 2.
[tex](2x)/2=(62)/2[/tex]
Simplify.
[tex]x=31[/tex]
The variable is equal to 31.

By how much peter is overweight he is 105 kg his aim is to lose 500 g per week if he manages this how many weeks will it be until he is 90 kg
Answers
105 - 90 = 15kg
500g = 1/2 kg
Peter is 15kg overweight.
15 x 2 = 30
It will take him 30 weeks for this.
Hope This Helps You!
Good Luck :)
So lets convert 500g to kg. We do this by using a conversion factor.
[tex]1g = 0.001kg = 1g:0.001kg = \frac{0.001kg}{1g}[/tex]
Now that we know this conversion factor lets set it up.
[tex]500g \times \frac{0.001kg}{1g} = 0.5kg = \frac{1}{2}kg [/tex]
Ok now we know Peter wants to lose 0.5 kg or [tex]\frac{1}{2}kg[/tex] a week.
Peter wants to lose 1/2 kg a week so we use x for weeks
Lost of weight per week
[tex] \frac{1}{2}x [/tex]
Next, it tells us that Peter wants to be 90 kg. So he needs to lose 15kg.
105 - 90 = 15kg
Now we need to find out how many weeks will it be untill he is 15kg. So, Lost of weight per week = 15kg
[tex] \frac{1}{2}x = 15 [/tex]
Now solve for x in [tex] \frac{1}{2}x = 15 [/tex]
[tex] \frac{1}{2}x = 15 [/tex]
[tex] 2 \times \frac{1}{2}x = 15 \times 2[/tex]
[tex] x = 30 [/tex]
So it will take 30 weeks at 1/2kg a week to lose 15kg

The sum of two consecutive odd integers is 32. Find the integers
Answers
They have to be both odd
15 + 17 = 32
hope this helps
Call the first number n:
n + n + 2 = 32
Simplify:
2n + 2 = 32
Subtract 2 from both sides:
2n + 2 - 2 = 32 - 2
Simplify:
2n = 30
Divide both sides by 2:
2n/2 = 30/2
Simplify:
n = 15
The numbers are 15 and 17.
