Answer:
Simplify 2(x+1)\times 22(x+1)×2 to 4(x+1)4(x+1).
4(x+1)=324(x+1)=32
2 Divide both sides by 44.
x+1=\frac{32}{4}x+1=
4
32
3 Simplify \frac{32}{4}
4
32
to 88.
x+1=8x+1=8
4 Subtract 11 from both sides.
x=8-1x=8−1
Answer:
Step-by-step explanation:
145+15x>490. subtract 145 from both sides
15x>345, divide both sides by 15
x>23
So she will need to run for more than 23 weeks to reach her goal.
Answer:
No, it is not tangent
Step-by-step explanation:
XY can only be tangent to the circle if it forms a right angle to the diameter. To test this, you need to figure out whether the three parts of the triangle make a Pythagorean triple. 8.5×2=17, and 17^2+5^2 is 314, which is not equal to 20 squared. Therefore, it is not tangent. Hope this helps!
Answer:
0.95
Step-by-step explanation:
You would change the denominator and get the lowest common denominator. Thos would be 30. You would do 11/6 x 5/5 = 55/30. Then do 3/5 x 6/6 = 18/30. Then add 55/30 + 18/30 = 73/30 and simplify.
