Answer:
Step-by-step explanation:
What is the problem, can you write it better pls?
Answer:
x = - 3 and x = 1
Step-by-step explanation:
4x - 2 - 2x = x - 5, that is
2x - 2 = x - 5 ( subtract x from both sides )
x - 2 = - 5 ( add 2 to both sides )
x = - 3
----------------------------------------
- (x + 3) = 2x - 6 ← distribute left side
- x - 3 = 2x - 6 ( subtract 2x from both sides )
- 3x - 3 = - 6 ( add 3 to both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1
How many solutions does the following equation have? 5(x + 3)= 5x + 3

you are buying decorations for a birthday party. the before tax total for 3 rolls of crepe paper and 20 balloons is $11.40. after you start decorating, you need more supplies. you buy 2 more rolls of crepe paper and 10 more balloons for $7.20 before tax. how much did each cost?
please help with an explanation.
Answer & Step-by-step explanation:
Let's have
C = Creepers
B = Balloons
1) 6C + 20B = 11.9
2) 2C + 15B = 6.05
Eliminate
16C + 20B = 11.9 x3
-2C + 15B = 6.05 x4
18C + 60B = 35.7
-8C + 60B = 24.2
10C/10 = 11.5/10
C = 1.15

Step-by-step explanation:
A bag contains 5 red marbles, 8 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be red?
Without replacement, the probability that all three marbles drawn will be red is 0.01.
What is the probability?Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.
Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)
5/17 x 4/16 x 3/15 = 0.01
The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%
How to calculate probability?
We are given;
Number of red marbles = 5
Number of blue marbles = 8
Number of Green marbles = 4
Total number of marbles = 5 + 8 + 4
Total number of marbles = 17
Probability of first being red = 5/17
Probability of second being red = 4/16
Probability of third being red = 3/15
Thus;
P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)
P(all three marbles drawn are red) = 0.0147
Approximating to nearest tenth of a percent = 0.015 = 1.5%

A principal of $2900 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 14 years?
Answer:
$6774.4
Step-by-step explanation:
Given data
P=$2900
r= 6.25%
t= 14 years
A=???
The compound interest formula is given as
A=P(1+r)^t
substiute
A= 2900(1+0.0625)^14
A= 2900(1.0625)^14
A= 2900*2.336
A= $6774.4
Hence the final amount is $6774.4

Determine how (if possible) the triangle can be proven similar:
Answer:
Not similar
Step-by-step explanation:
You can only find the vertical angles at the intersection.
So, you know they share one angle.
That is not enough information to prove similarity.
Therefore, I'd say they're not similar.
