Answer:
21
Step-by-step explanation:
Ok, so this may be confusing but I’ll explain.
Here is a very simplified diagram:
1-2, 1-3, 1-4, 1-5, 1-6, 1-7
2-3, 2-4, 2-5, 2-6, 2-7
3-4, 3-5, 3-6, 3-7
4-5, 4-6, 4-7
5-6, 5-7
6-7
*Note- I did this in about 30 seconds and on my phone so it is very simplified *
Each number, 1-7, is supposed to represent a different ingredient and they are put together to represent the two-ingredient combinations.
For example: 1-2 could represent pepperoni and sausage, and 1-5 could represent pepperoni and olives. This would mean that the 1 represents pepperoni, 2 represents sausage, and 5 represents olives.
If you count the number of combinations in each row, there are 21 combinations. This is because I made sure there are no repeats (2-3 AND 3-2) and because there wouldn’t be any doubles (1-1 or 2-2)
L.H.S of 2x - 3 = 8 is
Answer:
5.5
Step-by-step explanation:
2x -3 = 8
then
2x = 8 + 3 = 11
means
2x = 11
then
x = 11 ÷ 2
x = 5.5
___________________
we change the sign (- or +)
then take the number to the other side of the equal (with the changed sign)
leaving the x alone so that we can answer the equation..
_____________
to make sure
2×5.5 -3 = .....
it will be 8
A triangle has side lengths of 23 in, 6 in, and 28 in. classify it as acute right or obtuse
Answer:
In this case, the side lenghths don't even form a triangle. Since that is not an option, the triangle would be acute.
Step-by-step explanation:
if c^(2 )> a^(2)+b^(2) then the triangle is obtuse.
if c^(2 )< a^(2)+b^(2) then the triangle is acute.
if c^(2 )= a^(2)+b^(2) then the triangle is right
Hope this helps :)
A group of students are going on a field trip. if the group takes 3 vans and 1 car, 22 students can be transported. if the group takes 2 vans and 4 cars, 28 students can be transported. write and solve a system of equations to represent the situation. fill in the blanks to indicate the number if students that can fit in each van and car?
Answer:
6 students.
Step-by-step explanation:
3v + c = 22 ---> c = 22 - 3v
2v + 4c = 28 ---> 2v + 4(22 - 3v) = 28
2v + 88 - 12v = 28
-10v + 88 = 28
- 88 - 88
- 10v = - 60
v = 6 students

Solve the following system of equations using the substitution method
y - 3x = 12
y = - 3
Answer:
x = 5
y = -3
as an ordered pair: (5,-3)
Step-by-step explanation:
if y = -3, then replace y in the first equation with -3.
-3 - 3x = 12
move -3 over to the other side by adding 3 to both sides.
3x = 15
x = 5
y = -3
Answer:
x = -5
y = -3
Step-by-step explanation:
Two equations
Solve using substitutition
y = -3
y - 3x = 12
_____________________
Since the first equation has y alone, we can plug it into the second equation for y.
(-3) - 3x = 12
-3 - 3x = 12
Add 3 to both sides :
-3x = 15
Divide -3 from both sides to get x alone :
x = -5
Now that we have x, plug it into x in the second equation :
y - 3(-5) = 12
y + 15 = 12
Solve for y :
Subtract 15 from both sides :
y = -3
the mass of a plastic triangle is 3g and rhe mass of a plastic square is 7 g Samson has a collection of plastic triangles and squares if there are 14 triangles and squares altogether and their combined mass is 58 g calculate how many triangles and how many squares Samson has.
Answer:
4 squares
10 triangles
Step-by-step explanation:
t=3g
s=7g
t+s=14 t=14-s
3t+7s=58
substitute
3(14-s)+7s=58
42-3s+7s=58
reduce
4s+42=58
4s=16
s=4
t=14-4=10

84 people attended
a play. Of the 84
students, 1/3 of
them were parents.
How many parents
were in the
audience?
Answer:
There were 28 parents in the audience.
Step-by-step explanation:
So basically we have to find out what 1/3 of 84 is.
So to find out what 1/3 of 84 is, I will divide 84 ÷ 3 = 28
So 1/3 of 84 is 28

f(x) = —x^2 – 3x
Find f(10)
Step-by-step explanation:
f(x) = —x^2 – 3x
f(10)={-10}²-3×10=100-30=70
Answer:
f(10) = 70
Step-by-step explanation:
In this question, plug in "10" to "x" and solve.
Solve:
f(10) = -(10)^2 - 3(10)
f(10) = 100 - 3(10)
f(10) = 100 - 30
f(10) = 70
Your final answer would be f(10) = 70

Misty purchased a car several years ago for 21,459. The value of the car depreciated at a rate of 15% annually. What was the value of the car after 5 years? Round your answer to the nearest whole dollar.
Answer: $9,521
Step-by-step explanation:
In such cases, you should use the future value formula which is:
Future value = Amount * (1 + rate) ^ number of periods
Rate = -15% because the value is decreasing.
Future value = 21,459 * (1 -15%)⁵
= $9,521
Car will be valued at $9,521 after 5 years.
