Answer:
3 pens.
Step-by-step explanation:
x+y=7 where x is # of pens and y =# of pencils
3x + 2y= $18
from first equation, x=-y+7 so substitute that into other equation
3(-y+7)+2y=18
-3y+21+2y=18
-y=18-21
-y=-3
y=3
now replace y =3 into first equation
x+3=7
x=4

Tylers mom had a coupon for four dollars each of the train tickets.If they bought If they bought five train tickets and paid a total of $145, what was the original cost of each ticket?
Answer:
The original cost of each ticket will be = $33
Step-by-step explanation:
Number of coupons Tylers mom had = 5
The value of each coupon is = $4
Total value of coupons = 5 x 4 = $20
In order to find the original cost of the ticket, we just have to add the value of coupons to the amount paid for tickets.
The original cost of tickets = $145 + $20
The original cost of tickets = $165
Thus, the original cost of each ticket will be = 165 / 5
Thus, the original cost of each ticket will be = $33
there are 8 apples and 11 oranges in a bag. what is the ratio of the apples to oranges?
Answer:
8:11
Step-by-step explanation:
For every 8 apples, there are 11 oranges.
Answer:
8 : 11 = 8 : 11
Step-by-step explanation:
Divide both terms by the GCF, 1:
8 ÷ 1 = 8
11 ÷ 1 = 11
The ratio 8 : 11 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
8 : 11 = 8 : 11

Martha has a 4-digit combination lock on her briefcase and has forgotten the combination. Each of the four digits on her lock can read any digit from 0 through 9. If she
knows that the first digit is 6, and the second digit is prime, how many numbers must Martha try before the lock is sure to open? (Note: Neither "0" nor "1" are prime
numbers!)
Answer:
224
Step-by-step explanation:
1st Digit - 9 (1 way)
2nd Digit - 2, 3, 5, 7 (4 ways)
3rd Digit - (10-2) ways
4th Digit - (10-3) ways
Therefore, the number of ways are 1 × 4 × 8 × 7

What is P(odd)?
Write your answer as a fraction or whole number.
Answer:
1/3
Step-by-step explanation:
Does the spinner only have these 3 sections?
If so, the probability of spinning an odd number is 1/3. There are a total of 3 possibilities (denominator), and only 1 is odd (numerator).
The P(odd) is the probability of spinning an odd number that would be equal to 1/3.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes

Find area AND perimeter of the shape
Step-by-step explanation:
for the perimeter...
18-6=12
that's to get the slant side
perimeter=10+6+12+12+20
=60
for the area I'm not sure how to solve it sorry!!
Answer:
10 x 6 = 60
20 + 10 = 30, 30 x 12 x 1/2 = 180
180 + 60 = 240 cm2 is your area
6 + 6 = 12, 12 + 10 = 22, 22 + 20 = 42
Now lets find hypotenuse:
10 - 20 = 10, 10 divided by 2 = 5
5^2 + 12^2
25 + 144 = 169
Square root of 169 is 13
Add perimeters:
42 + 13 = 55 cm is your perimeter.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). The vertex of a parabola is (-2, -20), and its y-intercept is (0, -12).
The equation of the parabola is y = x2 + x + .
Step-by-step explanation:
-12 = a(0+2)²-20
-12=4a -20
4a = 20-12
4a=8
a=2
y = 2x²+ 8x -12
=> y = 2 x² + 8 x + -12

If two angles are both vertical and supplementary, can we determine the angles? Is it possible to be both vertical and complementary? If so, can you determine the angles? Explain how you know ASAP
Answer:
Two angles can be vertical and supplementary only if they add up to 90 degrees because there perpendicular.
Step-by-step explanation:
Answer:
90 + 90 = 180, 45 + 45 = 90
Step-by-step explanation:
Supplementary angles add up to 180 and to be vertical angles they need to be equal to each other so 2x = 180
x = 90
Hence both angles will be equal to 90
Complementary angles add up to 90 and as previously stated, to be vertical angles they need to be equal to each other so 2x = 90
x = 45
Hence both angles equal to 45

What is the diameter of a hemisphere with a volume of 272\text{ m}^3,272 m
3 , to the nearest tenth of a meter?
Answer:
D = 10.1m
Step-by-step explanation:
We know that the volume of a sphere of radius R is:
V = (4/3)*pi*R^3
where pi = 3.14
A hemisphere is half a sphere, then the volume of an hemisphere is half of the volume of a sphere, then the volume of a hemisphere of radius R is:
V' = (1/2)*(4/3)*pi*R^3
Now, we know that our hemisphere has a volume:
V' = 272m^3
Then we can solve the equation:
272m^3 = (1/2)*(4/3)*pi*R^3
For R.
(we want the diameter, but remember that the diameter is equal to two times the radius, so finding the radius is a good start)
272m^3 = (1/2)*(4/3)*pi*R^3
272m^3 = (4/6)*3.14*R^3
272m^3*(6/4*3.14) = R^3
∛( 272m^3*(6/4*3.14) ) = R = 5.06 m
And the diameter is two times that, so we get:
D = 2*5.06m = 10.12 m
Rounding this to the nearest tenth of a meter (first digit after the decimal dot), we get:
D = 10.1m
