Answer:
x=17
Step-by-step explanation:
It is a right angle
so if we do
90-39=51
then we do 51/3
which will give us the answer of 17
3(17)= 51
39+51=90
Answer:
90 minutes
Step-by-step explanation:
We know that distance = rate * time
We know the distance and the rate, and need to find the time
distance = 60 miles
rate = 40 mile per hour
60 = 40 * t
Divide each side by 40
60/40 = 40t/40
1.5 = t
1.5 hours
Now we need to change it to minutes
1.5 hours * 60 minutes/1 hours = 90 minutes
400,000
because if you do 10 with the exponent of 5 you'll get 100,000 multiply by 4 = 400,00
1000x2 = 2000
x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24
