3x+2y=11
y=5x-1
Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1
3x+10x-2=11
y=5x-1
13x=13
y=5x-1
Now substitute the x to find the y:
x=1
y=5-1=4
Answer:
your age is 95
Step-by-step explanation:
so what minus 400 gets you 210? 190 so you took 190 away from 400 or reduced it by 190 and got 210 but you said that it was twice your age so we can do the inverse of times 2 which is divided by 2 and you would get 95.
4.50 is 15% of 30
15x 30 = 450 so it all adds up. Hope you get a good score
54 and 72 Goes in the "Divisible by 6 and 9" column
90 goes in the "Divisible by 5 and 9" column
84 and 96 goes in the "Divisible by 2 and 6" column
hope this helps!
Answer:
B
Step-by-step explanation:
logₓ 7 = 3
x³ = 7
Take cube root both sides
