This, you will have to use your calculator for, but I can still explain it.
First off, 9x10^-3 is equivalent to 0.009
Second: 2.4x10^-5 is equivalent to 0.000024
Parenthesis
Exponents
Multiple
Divide
Addition
Subtraction
PEMDAS is the order you go in always, if it's multiple or division, you do whichever one comes first, same with addition and subtracting, so left to right
FIRST: do 0.000024 / 0.0012 = 0.02
0.009 + 0.02 (answer above) = 0.29
Answer:
4
Step-by-step explanation:
1/2 ×base ×height =40
1/2 × (x+4) × x=40
(x+4) + x =80(40×2)
x×x + 4x =80
x×x + x =80/4
x×x +x =20
x=4
hope it helps....plz mark me brainliest :)
Answer:
40/9 or 4.444444
Step-by-step explanation:
a = 4 b = 5
8b/b + a
8(5)/b + a
40/b + a
40/ 5 + 4
Answer = 40/9
It has 3 terms (y²) and (-3y) and (12), so it's a trinomial.
The degree of a polynomial with 1 variable is the highest exponent...so it has a degree of 2. But if it had more then 1 variable, it would be different.
ANSWER: The polynomial is a trinomial with a degree of 2
Answer:
x = 1, y = -5
Step-by-step explanation:
2x + 5y = (-23) (1)
5x + 13y = (-60) (2)
Multiply (1) by 5 and (2) by 2 to eliminate x
10x + 25y = -115 (3)
10x + 26y = -120 (4)
Subtract (3) from (4)
26y - 25y = -120 - (-115)
y = -120 + 115
y = -5
Substitute y = -5 into (1)
2x + 5y = (-23)
2x + 5(-5) = -23
2x - 25 = -23
2x = -23 + 25
2x = 2
x = 2/2
x = 1
x = 1, y = -5
