Statement given :
→Sara says "If you subtract 11 from my number and multiply the difference by -3 , the result is -54 .
<u>To</u><u> </u><u>f</u><u>ind</u><u> </u>:
SOLUTION :
Let us take Sara's Number be “x”.
★According to Question,
→ x - 11×(-3)= -54
→ x + 33 = -54
→ x = -54-33
→ x = (-87)
let's verify our number,and check whether it's correct or not !
x - 11×(-3)= -54
<u>Putt</u><u>ing</u> <u>the</u> <u>value</u> <u>of</u> <u>x</u>
(-87) - 11 × (-3)= -54
(-87) + 33 = -54
(-54) = -54
Hence, The L.H.S. = R.H.S.
Thus,our number is Verified.
Answer:
Or
Step-by-step explanation:
The given expresion is 2y-8+4y.
We want to find an expression that is equal to 2y-8+4y.
We need to group like terms to obtain:
We can now combine the like terms to get:
We can factor 2 to obtain:
Answer is A because x+x+70=180 subtract 70 in 180 so 2x=110 110 divided by 2 is 55 so x=55
She could run 1,2,3,4,5,6,7,8,9,10 miles to get less than 26 miles
Answer:
5/16.
Step-by-step explanation:
The probability of getting a correct answer on one question is 1/2 and the probability of getting it wrong is 1 - 1/2 = 1/2.
The probability of the first 2 being correct and the next 3 wrong = (1/2)^5 = 1/32.
There are 10 possible combinations of this ( first wrong the 2nd and third right and last 2 wrong, etc).
So the required probability is 10 * 1 /32
= 10/32
= 5/16.
