Answer:
R=-21
Step-by-step explanation:
R/5-(-4.2)=0
r+(4.2)*5=0
r+21=0
r=-21
Hello!
Let's follow the BEDMAS rule.
First we should do everything inside the brackets. According to BEDMAS we should do multiplication first before subtraction:
(28 × 5 - 5 × 190)
28 × 5 = 140
5 × 190 = 950
(140 - 950) = -810
So now we have:
(-810 - 2 × 5^-2) / 2^3
Next, we do exponents so:
5^-2 = 1/25
2^3 = 8
(-810 - 2 × 1/25) / 8
(-810 - 2/25) / 8
(-20252/25) / 8 = -5063/50
So now we have:
(-5063/50)^4 × 288
If we plug the first term into a calculator and out it to the party of 4, we get:
105136058.7
So that number times 288 we get:
3.03x10^10 as the Correct Answer

Answer:
Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle.
The probability of rolling a 5 and rolling an odd number on a die is independent; rolling a 5 does not influence the probability of rolling an odd number the next time.
King or Jack is mutually exclusive; they cannot both happen at the same time.
Club or Queen is not mutually exclusive; they can happen at the same time.
King or Ace is mutually exclusive; they cannot both happen at the same time.
Answer:
X=12
Step-by-step explanation:
8×-6=2(4×+3)
8x-6=8×+6
8×-8×=6+6
×=12
