Answer:
her grandson would be 7 and her granddaughter would be 5.
Step-by-step explanation:
their ages together is 12. we divide that by the two grandchildren, and adjust it to where they are to years apart.
12÷2=6
6+6 + adjusted = 5 and 7.
to fact check 5+7=12, and 7 is two numbers above 5.
The equation would be : 10y + 3x = 50
Hope this helps :)
3. 14 you can't round it it's already rounded
Step-by-step explanation:
You would start by using one of the equations to find y with x in the equation. You want to pick the easier one. I picked this one because it was evenly divisible.
5x+5y=50
5x=-5y+50
x=-y+10
Then you what to plug that in to the second equation and solve for y.
3(-y+10)+4y=32
-3y+30+4y=32
-3y+4y=2
y=2 (because you combined like terms)
Then you would plug back into the first equation and solve for x.
5x+5(2)=50
5x+10=50
5x=40
x=8
x=8, y=2
Answer:
An equation of a line is written in the form y=mx+b. ”m” is the slope and ”b” is the y-intercept. So, substituting the values, the equation is y=-4x+1.
