Step-by-step explanation:
Answer:
347 and 865
Step-by-step explanation:
Let the two number be x and y
Therefore, from the given information:
x + y = 1212
x - y = 518
Rewrite both equations to make x the subject:
x = 1212 - y
x = 518 + y
Equate equations and solve for y:
1212 - y = 518 + y
694 = 2y
y = 347
Substitute found value of y into one of the equations and solve for x:
x = 518 + 347
x = 865
Therefore, the two numbers are 347 and 865
Answer:
y = 0.5x - 5.5
Step-by-step explanation:
slope = 0.5, so this is the x coefficient.
y intercept = -2 - (7 x 0.5) = -5.5
Answer:
21
Step-by-step explanation:
49 - 4 x 49 / 7 =
49 - 196 / 7 =
49 - 28 =

First of all, it would be easier to write down this problem, wouldn't it? ;)
6 x 6 + 9 ÷ 10^2
According to PEMDAS, we will start off with the exponent part of the equation, since there are no parenthesis.
10^2 = 100
Now, we will multiply 6 x 6, which equals 36.
Then, you will divide 9 by 100, which makes 0.09. Now we can add 0.09 to 36 and see what we get as a final answer.
0.09 + 36 = 36.09
FINAL ANSWER --
36.09
