Answer:
remember to round numbers to 1 significant figure
Step-by-step explanation:
usually in an exam when you're asked to estimate the answer to a calculation, usually you round each number to 1 sf and then work on from there.
Answer:
The correct answer is J. 10
Step-by-step explanation:
The answer to the equation 4/5 divided by 2/25 is equal to 10.
The correct answer is letter C, 2y=26.
When you add both equations you get that answer.
Answer:
1, 3, 4, and 10
Step-by-step explanation:
To get a y value, substitute the x value into the equation they gave you (y = 3x - 5). For the x value 2:
y = 3(2) - 5
y = 6 - 5
y = 1.
To get a missing x value, solve for x in the equation they gave you. You were given the y value, so you can substitute that into the equation.
(4) = 3x - 5
Add 5 to both sides
9 = 3x
Divide both sides by 3
3 = x
Do the same with 7
(7) = 3x - 5
Add 5
12 = 3x
Divide by 3
4 = x
For the last one, you're given x so substitute it into the equation:
y = 3(5) - 5
y = 15 - 5
y = 10
Answer:
s = 6
Step-by-step explanation:
We know a square has all equal side lengths. So we would divide the square by four to get one side length.
24/4 = 6
s = 6
