i’m not too sure lol but i tried!!
Answer:
35
Step-by-step explanation:
i'm either really confused or there's a lot of weird typos in this
assuming there's just a lot of weird typos, this is how you would solve it:
1. plug in -1 for a and 3 for b
2. multiply 3 by -1
3. multiply 3 by -3
4. add 50 to -9
5. subtract 6 from 41
Answer:
6 years
Step-by-step explanation:
So each person's age can be represented as a linear equation, since each year our age increases by 1. It can be represented in the slope-intercept form: y=mx+b. The slope in this case is going to be 1, since the time is going to be years, and each year everyone's age goes up by 1 (of course if you're still alive...) and y-intercept in this case represents their current age.
So the father can be represented as: y=x+38
The sons can be represented as: y = x+13 and y=x+5
The daughter can be represented as: y=x+8
So adding up all his children you get:
(x+13)+(x+5)+(x+8)
This gives you the equation:
3x+26
Now set this equal to the father's age to solve for x (in this context it's years)
3x+26=x+38
Subtract from both sides
2x+26=38
Subtract 26 from both sides
2x=12
Divide both sides by 2
x=6
So in 6 years the father will be the same age as his children put together
Answer:
71%
Step-by-step explanation:
I think the easiest way to think of this is to pretend that there are a total of 100 students at the high school, so that means the amount of people who work part time is 45% of 100 = 45 people. If 60% of those students love math, you do 0.6 * 45 = 27 people.
Next, 80% of the students who do not have a part time job (100 - 45 = 55) love math, so 0.8 * 55 = 44 people.
44 + 27 = 71, so the percent is 71/100 = 71%.
let me know if any part of that doesn't make sense
Answer:
x + 15 = 3 (x - 5)
William’s current age: 15. Years old
Step-by-step explanation:
x + 15 = 3(x-5)
x + 15 = 3x - 15
15 + 15 = 3x - x
30 = 2x
x = 15
