Answer:
I hope this helps
Step-by-step explanation:
So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers. Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.
We know x + y + z = 83.
Since the third number is twice the second, we say that z = 2y.
Since the second number is seven less than the first, we say that y = x - 7. We can rewrite this as x = y + 7.
Now all three can be written in terms of y.
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83.

Use the bag of marbles below to answer questions 5 and 6.
Imagine that you have a bag of marbles with
4 red marbles, 5 blue marbles, 3 pink marbles, and 7 green marbles
5) What is the probability you draw a pink marble?
3/19
6) What is the probability you draw a red or blue marble?*
Answer:
5) 3/19
6)9/19
Step-by-step explanation:
there are 19 marbles altogether
Answer:
It should be 9/19
Step-by-step explanation:
since you have the option to draw a red or blue you add those numbers together. So it's asking what is the probability of drawing either marble.

Mikayla subtracted 4 from both sides in the beginning when she should've added it to both sides to cancel it out on the right. the correct answer should actually be x=1
Answer:
Mikayla subracted 4 from both sides, not add. She was supposed to add so that the -4 can cancel out.
The correct answer would be x=1

house. How much would plumber Bob charge for working 5 hours?
A) $125
B) $100
C) $75
D) $115
Answer:
D) $115

15 x 5 = 75
75 + 40 = 115
Answer:
D is the answer
Step-by-step explanation:
15x5=75
75+40=115

Et of y=x2-4 and + y + 2 = 0?
The equation y = x2 – 4 + y + 2 = 0 can be solved by completing the square.
What is equation?An equation is a mathematical statement that to express our equal. Is consist of two expression separated by an equal sign and can contain numbers, variables and operators. Equation get be used to solve problems make prediction and describe relationship between different quantities. Equation can be can also be used to represent physical laws and other phenomena.
First, subtract y from both sides of the equation to get x2 - 4 + 2 = y. Then, subtract 2 from both sides of the equation to get x2 - 6 = y. Finally, add 9/4 to both sides of the equation to get (x - 3/2)2 = 9/4 + y.
This equation can be solved by taking the square root of both sides to get x - 3/2 = ±√(9/4 + y). Finally, add 3/2 to both sides of the equation to get x = 3/2 ±√(9/4 + y).

28 - 4u
I don’t know how to factor 28-4u so if anyone can help thank you
Answer: 4(7-u)
Step-by-step explanation:
In order to factor, you have to find the GCF (Greatest Common Factor)
28:1, 28, 2, 14, 4, 7
4:1, 4, 2
The greatest common factor here is 4.
You can factor out 4 from this equation, therefore making it 4(7-u)
