Simplify:
Solution ===> −7 + 12 − 3(50 − 4(2 + 3)) =========> -85
= 5 − 3(50 − 4(2 + 3))
= 5 − 3(50 − (4)(5))
= 5 − 3(50 − 20)
= 5 − (3)(30)
= 5 − 90
= −85
Answer ================> -85
Simplify:
1/3 + 6(2/3 - 1/6)^2
1/3 + 6(1/2)^2
1/3 + 6(1/4)
1/3 + 3/2
Answer =======> 11/6 =========> Decimal =======> 1.833333.....
Hope that helps!!!! : )
The answer is 23 1/3. First, you need to add 280 to both sides of the equations in order cancel out 280 and get 12x by itself. But remember whatever you do to one side of an equation, you must to do the other. So now you have 12x=280. Now divide both sides of the equation by 12 in order to get x completely isolated. 280 divided by twelve is 23 1/3.
Answer:
38 and 39
Step-by-step explanation:
Since the two integers are consecutive, then one is one larger than the other. Therefore, lets call them x and x+1. We can now set up the following equation:
x+(x+1)=77
2x+1=77
2x=76
x=38
x+1=39
Hope this helps!
Answer: X = 7√2
Step-by-step explanation:
Let first Consider triangle BDC,
Cos C = adjacent/ hypothenus
Cos C = 7 / x ...... (1)
Also, let consider triangle ABC
Cos C = adjacent / hypothenus
Cos C = x / 14 ....... (2)
Since angle C is the same, equate equation 1 to 2
7/ x = x / 14
Cross multiply
X^2 = 98
Make x the subject of formula
X = sqrt (98)
X = sqrt ( 49 × 2 )
X = sqrt (49) × sqrt (2)
X = 7 sqrt(2)
X = 7√2
