Mrs. Potter was going through her Halloween candy to see which kind she would bring to school. She sorted using decimal values. .17 of her 100 pieces were black licorice. .42 were m&m's. .12 were skittles. .09 were smarties. .14 were lollipops and .06 were gum drops. Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Answer:
23%
Step-by-step explanation:
She sorted using decimal values.
We convert the decimals to percent
.17 of her 100 pieces were black licorice.
.17 = 0.17 × 100 = 17%
.42 were m&m = 0.42 × 100 = 42%
.12 were skittles. = 0.12 × 100= 12%
.09 were smarties = 0.09 × 100= 9%
.14 were lollipops = 0.14 × 100 = 14 %
.06 were gum drops. = 0.06 × 100= 6 %
Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Licorice = 17%
Gum drops = 6%
The percent of her candy that she brought to school = 17% + 6%
= 23%
The percent of her candy that she brought to school is 23%

Answer:
Plug in what you are given for y then solve for x:
[tex]-2 + 2 = -3(x - 4)\\\\0 = -3(x - 4)\\\\0 = -3x + 12\\\\-12 = -3x\\\\4 = x[/tex]
The missing value would be 4.

wich he is only sure of the answers he
gave
five questions, he answers the remaining
five at randone
What is the probability of that accredits at
least six in the exam?
so
Answer:I’m guessing 3 because there’s 10 he knows 5 are right so that’s half of the test, so he would receive half of the credits and half of 6 is 3.
Step-by-step explanation:
10 oranges and 20 grapefruits weigh 35 pounds total. 16 oranges and 10
grapefruits weigh 23 pounds total. How much would 13 oranges and 15
grapefruits weigh?
A 28 pounds
B 29 pounds
C 30 pounds
D 58 pounds
Answer:
B
Step-by-step explanation:
oranges weigh 0.5 and grapefruits weigh 1.5
The required: 13 oranges and 15 grapefruits would weigh 29 pounds.
The correct option is A.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.
Let's use a system of equations to solve this problem:
Let's call the weight of an orange "x" and the weight of a grapefruit "y". Then we can write:
10x + 20y = 35 (equation 1)
16x + 10y = 23 (equation 2)
We want to find the weight of 13 oranges and 15 grapefruits, which we can represent as:
13x + 15y
In this case, we can multiply equation 1 by -8 and equation 2 by 15:
-80x - 160y = -280 (equation 1, multiplied by -8)
240x + 150y = 345 (equation 2, multiplied by 15)
Now we can add the two equations to eliminate y:
160x = 65
Solving for x, we get:
x = 65/160
Now we can substitute this value of x back into one of the original equations to solve for y. Let's use equation 1:
10(65/160) + 20y = 35
Simplifying this equation, we get:
13/32 + 2y/4 = 7/2
Multiplying both sides by 32, we get:
13 + 16y = 112
Solving for y, we get:
y = 99/16
Finally, we can substitute these values of x and y into the expression for 13 oranges and 15 grapefruits:
13x + 15y = 13(65/160) + 15(99/16) = 29.0625
Therefore, 13 oranges and 15 grapefruits would weigh approximately 29.0625 pounds, which is closest to answer B, 29 pounds.

Answer:
for the first one its x=30
for the second one its x=6
Step-by-step explanation:
its x=30 because at the end if you do the problem yourself, you would have to multiply 5×6 which is 30.
im not sure why its x=6 on that one i might be wrong but i did it but im also confused on it but i tried so yeah maybe it is.
What is the slope of 1.5x+4.5y=18 ,and how do you know?
Answer:
m=-1/3
Step-by-step explanation:
The slope of this line is m=-1/3 because if you use the slope-intercept formula, y=mx+b, m is the slope. If you take this equation and plot two points on a line that has this equation, the slope will be negative if the line forms an obtuse angle on the 0 line. In this case, m=-1/3 as the line goes back 1/3 unit for every unit in this equation. Hope it helps!
Answer: the slope is -0.33... The does means that 3 is repeating.
Step-by-step explanation:
First we will convert the equation into slope intercept form, which is the same way of solving for y in the equation.
1.5x + 4.5y = 18 Solve for y by first subtracting 1.5x from both sides
-1.5x -1.5x
4.5y = 18 - 1.5x Now divide both sides by 4.5
y= 4- 0.33x
y= -0.33x + 4 Now the slope is the coefficient of the variable x which is the number that comes after the variable.
In this case, the slope is -0.33...

-6 = -1/2(9) + B
-6 = 4.5 + B
-6--4.5 = B

what is 3n-22= -20
Answer:
n = 2/3
Step-by-step explanation:
3n - 22 = -20
Add 22 to both sides
-20 + 22 = 2
3n = 2
Divide both sides by 3
2 / 3 = 2/3
n = 2/3
Let me know if I've done something wrong :)
Answer:
