10
Step-by-step explanation:
x + 5 = 2x - 5
x + 5 <u>- x </u>= 2x - 5 <u>- </u><u>x</u>
5 = x - 5
5 + 5 = x
<u>10 = x</u>
Answer:
C (the last one)
Step-by-step explanation:
On number line #3, the point is two digits after the 1 and three digits after 1.5. That shows it is 1.2, so it's C
Hope this Helps!
This is what irrational means:
A number that cannot be expressed as a ratio between two integers and is not an imaginary number. If written in decimal notation, an irrational<span> number would have an infinite number of digits to the right of the decimal point, without repetition.

so i think its the 3rd one but im not fully sure. I'm NOT that good at math
Hope this Helps!! :-)
Answer: the shortest side is 30m
Step-by-step explanation:
Let the shortest side be a meters
If side 2 is 16m longer than the shortest side, then it is (16+a)meters.
The same goes with side 3.
Then,
a + (16+a) + (16+a) = 122m
32 + 3a = 122m
Collecting like terms together,
3a = 122 - 32
3a = 90
Divide by coefficient of a
3a/3 = 90/3
a = 30 meters
Check:
30 + (16+30) + (16+30)
30 + 46 + 46 = 112
Answer:
3/4
Step-by-step explanation:
Given the following :
Number of boxes = 2
First box :
White balls = 3
Blue balls = 2
Second box:
White balls = 4
Blue balls = 1
What is the probability that Frida picked a ball from the first box if she has selected a blue ball?
Probability (P) = (required outcome / Total possible outcomes)
Probability of picking first box : P(F) = 1/2
Probability of not picking second box :P(S) 1/2
Probability of picking blue from first box : P(B | F) = 3/5
Probability of picking blue, but not from first box : P(Blue not from second box) P(B|S) = 1/5
probability that Frida picked a ball from the first box if she has selected a blue ball?
P(F) * P(B|F) ÷ (P(F) * P(B|F)) + (P(S) * P(B|S))
(1/2 * 3/5) ÷ ((1/2 *3/5) + (1/2 * 1/5)
3/10 ÷ (3/10 + 1/10)
3/10 ÷ 4/10
3/10 * 10/4
= 3/4
