Answer:
x=482
Step-by-step explanation:
First: x-411=71
Add 411 to both sides, which cancels out the -411 leaving just x.
You add 411 to 71 getting 482.
Answer:
56,500,000.
Step-by-step explanation:
56,477,812 rounded to the nearest hundred thousand:
The 4 is in the hundred thousands place, so we'll look at the next digit to the right of that, which is the 7:
56,<u>4</u>77,812
Since 7 is more than 5, we'll have to go up a number, which will be the 4. Afterwards, we'll have to replace all the digits after the 4 with zeros.
56,500,000.
The answer is A. 240 b/c 47*86= 4042
3200+240+560+42=4042
Answer:
Fifty more than half the number of the oranges is one-hundred-and-twenty.
The sum of fifty and half the number of oranges is the same as one-hundred-twenty.
Step-by-step explanation:
The equation is 50 + one-half m = 120.
Assume the number of oranges=m
50+1/2m=120
1/2m=120-50
1/2m=70
m=70÷1/2
=140
All statement that applies includes:
1. Fifty more than half the number of the oranges is one-hundred-and-twenty.
50+1/2m=120
2. The sum of fifty and half the number of oranges is the same as one-hundred-twenty.
50+1/2m=120
Martha can use the two statements above to communicate the correct equation
Answer:
a) y=1/3 sqrt(x+1)
b) 2/3
c) 224
Step-by-step explanation:
a) y varies directly to sqrt(x+1)
means there is some constant k such that y=ksqrt(x+1)
y=1 when x=8 (plug this in and find k) 1=ksqrt(8+1)
1=ksqrt(9)
1=k(3)
1/3=k
So the equation is y=1/3 * sqrt(x+1)
a) y=1/3 *sqrt(x+1)
b) what is y when x=3 if you have y=1/3 * sqrt(x+1)
Plug in 3 for x
y=1/3 *sqrt(3+1)
y=1/3 *sqrt(4)
y=1/3 *2
y=2/3
b) 2/3
c) what is x when y=5
Plug in 5 for y
5=1/3 *sqrt(x+1)
multiply both sides by 3
15=sqrt(x+1)
square both sides
225=x+1
subtract 1 on both sides
224=x
c) 224
