Step-by-step explanation:
12/6.5
substitution method
a=-b+5
2b+a=11
Answer:
a = -1
b = 6
Step-by-step explanation:
a = -b + 5
2b + a = 11
2b + a = 11
2b + (-b + 5) = 11
2b - b + 5 = 11
b + 5 = 11
b = 11 - 5
b = 6
2b + a = 11
2(6) + a = 11
12 + a = 11
a = 11 - 12
a = -1

Question Help
Think About the Process A jar contains only pennies, nickels, dimes, and quarters. There are 29
pennies, 16 dimes, and 17 quarters. The rest of the coins are nickels. There are 74 coins in all. How
many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could
you use to find n?
Answer:
62 coins are not nickels. you could just add the pennies, dimes, & quarters. those totals are given. So
29+16+17= 62
or if you want to impress then start with the total and subtract each given coin count
74-29-16-17=12
74-12=62

WILL GIVE BRAINIEST!!! IF UR ANSWER IS RIGHT
Answer:
-1
Step-by-step explanation:
the slope of this one is y=x-21
in order for it to be perpendicular the sign changes and the slope flips
but because the slope is 1 you just change the slope to -1
Choose the expression that represents a quadratic expression.
O 6x4 - 5x3 + 3x2 -7x - 8
) 5x3 + 3x2 -7x - 8
O 2x2 + 3x - 1
. 3x - 1
Answer:
3) 2[tex]x^{2}[/tex] + 3x - 1
Step-by-step explanation:
A quadratic expression is an expression involving a squared term
It can be written as y = a[tex]x^{2}[/tex] + bx + c, where a ≠ 0
// note that here b and c can be equal to 0
1) 6[tex]x^{4}[/tex] - 5[tex]x^{3}[/tex] + 3[tex]x^{2}[/tex] - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a quartic function, since the unknown variable x in forth degree. It can be written as y = a[tex]x^{4}[/tex] +b[tex]x^{3}[/tex] +c[tex]x^{2}[/tex] + dx + e, where a before [tex]x^{4}[/tex] ≠ 0
2) 5[tex]x^{3}[/tex] + 3[tex]x^{2}[/tex] - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a cubic function, since the unknown variable x in third degree.
3) 2[tex]x^{2}[/tex] + 3x - 1 is correct
4) 3x - 1 is incorrect because there is no squared term. You could also say that here a = 0 and write it as y = 0 * [tex]x^{2}[/tex] + 3x - 1. It is also called a linear function because if you'd draw a graph, it would be a line

Billy has 8 red marbles, 6 blue marbles, and 4 green marbles in a jar.
What is the probability that Billy would select a red marble?
A. Between 10% and 20%
B. Between 20% and 30%
c. Between 30% and 40%
D. Between 40% and 50%
Answer:
A
Step-by-step explanation:
pick A cause 8 6 and 4 = 18
which equation represents the line that has a slope of 4 and passes through the point (2, 7)?
(A) y = 4x - 1
(B) y = 4x + 15
y=x+4
D y =
= 2x-4
Answer:
A) y = 4x - 1
Step-by-step explanation:
y = mx + b
y = 4x + b
7 = 4(2) + b
7 = 8 + b
-1 = b
y = 4x - 1

A triangle has a perimeter of 15 feet. Side B is one foot longer than side A. Side C is two feet longer than side A. What is the length of each side.
Answer:
Side A = 4
Side B = 5
Side C = 6
Step-by-step explanation:
In the following equation, variable a is the length of Side A
a + (a + 1) + (a + 2) = 15
a + a + a + 1 + 2 = 15
3a + 3 = 15
- 3 - 3
3a (÷ 3) = 12 (÷ 3)
a = 4
Side A = 4
Side B = (a + 1) = (4 + 1) = 5
Side C = (a + 2) = (4 + 2) = 6

Solve the following equation: 4(x + 2) - 17 = 35
A: -11
B: 25/2
C: 15
D: 11
Answer:
D: 11
Step-by-step explanation:
4(x + 2) - 17 = 35
4x+8 - 17=35
4x-9=35
4x=35+9=44
x=44/4=11

Answer:
5 cookies left
Step-by-step explanation:
First you make the fraction equal by multiplying them
2/3 multiply both numerator and denominator by 4
= 8/12
Now you divide 60 by 12 to find the amount to make the denominator 60
60 divided by 12 = 5
8/12 multiply both numerator and denominator by 5
= 40/60
So now we know the amounts
She gave 40 away so she has 20 left (60 - 40 = 20)
Now make 3/4 numerator and denominator by equal to 20
Multiply them by 5
15/20
She had 5 cookies left

Answer:
15
Step-by-step explanation:
The median, is just the middle number in a set of numbers.
In this case, our set is: 17, 8, 15, 21, 12.
However, the set must be in increasing order, so the set becomes: 8, 12, 15, 17, 21.
This gives us the median, which is the middle number, to be: 15.
