The answer would be the first choice 4+b
Answer:
Numbers are 28 and -15
Step-by-step explanation:
Mark first number X, and second number Y, then:
x-y=43
and
x+y=13
We get system of two equations. Solve it by add both them together:
x-y+x+y=43+13
2x=56
x=28 we get first number
x+y=13
28+y=13
y=13-28
y=-15
Answer: -2049. Explanation: Use PEMDAS to solve the equation (parenthesis, exponents, multiplication/division, and addition/subtraction). First multiply the numbers that are being multiplied. You should get 44 + 27 - 2100 - 20. Now start from the beginning, and either add or subtract. The answer is -2049.
Answer:
.001
Step-by-step explanation:
You see it is the same numbers just it was moved 3 places to the left.
So the you would multiply it by .001 <------ there are 3 decimal places.
When you multiply them you get.
647.6*.001= .6476
First: Replace “x” with its known value. Since x = 3, plug it into the formula.
• F(3) = 6^3
Second: Solve the formula.
• 6^3 = 6 x 6 x 6 = 216
• F(3) = 216
