Answer:
x= -674
Step-by-step explanation:
Solve for x and check: x + 5 = 3
Solution
Solve for x and check: - 3x = 12
Dividing each side by -3, we obtain
Another way of solving the equation
3x - 4 = 7x + 8
would be to first subtract 3x from both sides obtaining
-4 = 4x + 8,
then subtract 8 from both sides and get
-12 = 4x.
Now divide both sides by 4 obtaining
- 3 = x or x = - 3
Solve for c: 3(x + c) - 4y = 2x - 5c
First remove parentheses.
Remember, abx is the same as 1abx.
We divide by the coefficient of x, which in this case is ab.
We don't know exactly what x is, so the best we can do is simplify these expressions. For 6/x+3, we know that both 6 and 3 are factors of 3, so using the distributive property, 3*2/x+3*1=3*(2/x+1). For 6(x+3), we can use the distributive property to get 6*x+6*3=6x+18. Good luck on the middle expression (I'd recommend using a similar strategy to the one I used), and feel free to ask any questions!
X=66 if it's a triangle, hope this helped!
Answer:
x=102
Step-by-step explanation:
(x-2)=20 (multiply both sides by 5)
x-2=100 (move the -2 to the right)
x=100+2 (add)
x=102
hope this helps :)
Answer:
Lateral surface area = 154cm²
Step-by-step explanation:
h = 10cm
pi = 22/7
base area = 154cm²
2πrh = 154cm²
2 × 22/7 × r × 10 = 154
440/7 × r = 154
r = 154 ÷ 440/7 = 2.45
r = 2.45
LSA of right circular cylinder = 2πrh
2 × 22/7 × 2.45 × 10
44/7 × 24.5 = 1078/7
1078/7 = 154
Therefore, lateral surface area = 154cm²
Hope it helps:)
