what is the probability of rolling a 3
Answer:
1/6
Step-by-step explanation:
Answer:
1/6 if rolled on a dice.
Step-by-step explanation:
There are 6 options on a dice, so 6 is the denominator.
There is only one chance to roll a 3, so 1 is the denominator.
Therefore, the answer would be 1/6.

the next algebra test is worth 100 points and contains 35 problems. multiple-choice questions are worth 2 points each and word problems are 7 points each. how many of each type of equation are there? Please leave steps.
Answer:
29 multiple choice questions, 6 word problems
Step-by-step explanation:
2x + 7y = 100
x + y = 35
y = 35 - x
2x + 7 (35 - x) = 100
2x - 7x + 245 = 100
-5x = -145
x = 29
29 + y = 35
y = 6

Manny begins the summer with $200 in his savings account. Each week he adds $85 to his account. Susan begins the summer with $95 in a savings account and adds $100 each week. When will Manny and Susan have the same amount of money in their accounts?
Answer:
7 weeks
Step-by-step explanation:
200 + 85w = 95 + 100w
-95 -85w -95 -85w
105 = 15w (divide both sides by 15)
7 = w
What is the equation of the line perpendicular to Y= 1/2x +6 that passes through the point (4,1)
Answer:
Step-by-step explanation:
y= mx+b is the general equation where m is the slope
y= 1/2 x +6 has the slope 1/2
perpendicular lines have the slope negative reciprocal
so the slope of the ⊥ line is -2
y = -x +b , yet for point (4, 1) the x=4 and y =1
1= -4 +b so b= 5
the equation of the ⊥ line is y= -2x+5
Which answer describes the sequence {1,3,7,15,…} as a mathematical statement?
Answer:
so just successive powers of 2
Step-by-step explanation:
1, 3, 7, 15, 31, 63, _? Add successive powers of 2 to the number: 1+2=3; 3+4=7; 7+8=15; 15+16=31; 31+32=63; 63+64=127.
The given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.
Given that,
To justify the given sequences 1,3,7,15.
Arithmetic progression is the series of numbers that have common differences between adjacent values
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here,
Given a sequence, 1,3,7,15
where first term A0 = 1
second term A1 = 1 + 2 = 3
third term A2 = 3 + 4 = 7
From above sequence we can conclude the general term for the sequence as, S = A(n-1) + (A(n-1) + 1)
Thus, the given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

Find the solution to the system: y=4x and 3x+2y=55
Answer:
x = 5, y = 20
Step-by-step explanation:
if y = 4x and 3x+2y = 55 then we can subtitude y as x.
We know that y = 4x so we can write 4x wherever we see y.
3x + 2y = 3x + 2(4x) = 55
3x + 8x = 55
11x = 55
x = 5.
And if y = 4x = 4(5)
y = 20
