Given that 4x - 5y = 12 find y when x= -3
Answer:
y ⁻²⁴⁄₅ or - 4.8Explanation:
4x - 5y = 12
x = -3
Insert -3 for 'x' in the equation4(-3) - 5y = 12
Remove the parentheses: (-a) = -a-4 · 3 - 5y = 12
Multiply 4 · 3: 12-12 - 5y = 12
Add 12 to both sides of the equation-12 - 5y + 12 = 12 + 2
Simplify-5y = 24
Divide both sides by -5-5y / -5 = 24 / -5
Simplifyy = ⁻²⁴⁄₅
Turn the fraction into a decimaly = -4.8

A history class is made up of 12 tenth graders and 9 eleventh graders. The tenth graders
averaged 77 on the midterm exam, and the eleventh graders averaged 91 on the midterm
exam. What was the average grade on the midterm exam for the entire class?
Answer:
They average 84%
Step-by-step explanation:
Just add 77 and 91 then divide it by 2. Hope this helps.
Answer:
83 is the correct answer if you just do it by adding 91 and 77 then diving it by 2 you would get 84 that is not what answer they are looking for. Took the test 83 is what they are looking for they want you to do the work.
Step-by-step explanation:
Tenth graders 12*77= 924
Eleventh graders 9*91= 819
924+819= 1,743
12 tenth graders and 9 eleventh graders
12+9 = 21
1,743/21 = 83

Jason bought some stickers on Saturday. He used 5 of them that same day. When he went back on Sunday, he bought 4 more stickers. Write an expression that represents the number of stickers Jason has.
Answer:
[tex]Stickers = s - ![/tex]
Step-by-step explanation:
Analysing the question, line by line.
Let the number of stickers be s/
So:
[tex]Stickers = s[/tex]
He used 5 of them
[tex]Stickers = s - 5[/tex]
He bought 4 more
[tex]Stickers = s - 5 + 4[/tex]
[tex]Stickers = s - ![/tex]

Of the last 60 people who went to the cash register at a department store, 15 had BLOND hair,
17 had BLACK hair, 26 had BROWN hair, and 2 had RED hair. Determine the experimental
probability that the next person to come to the cash register has BLOND hair. (answer as
simplified fraction)
Answer:
[tex]P(Blond) = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]Total = 60[/tex]
[tex]Blond = 15[/tex]
[tex]Black = 17[/tex]
[tex]Brown = 26[/tex]
[tex]Red = 2[/tex]
Required:
Determine the experimental probability of the next person having blond hair
This is calculated by dividing the number f people having blond hair with the total number of people.
i.e.
[tex]P(Blond) = \frac{Blond}{Total}[/tex]
[tex]P(Blond) = \frac{15}{60}[/tex]
Simplify
[tex]P(Blond) = \frac{1}{4}[/tex]

Solve 64 = h + 30.
K=?
Answer:
h = 34
Step-by-step explanation:
64=h+30
Step 1: Flip the equation.
h+30=64
Step 2: Subtract 30 from both sides.
h+30−30=64−30
h=34

What's the question?
When renting a limo for prom, the number of people varies inversely with the cost per person. Originally there were 4 people and the cost per person was $57. If the number of people changed to 12, what would be the new cost per person?
Answer:The new cost per person= $19 when there are 12 people
Step-by-step explanation:
Step 1
Let Number of people be rep as N
And Cost per person = C
such that the relationship of number of people which varies inversely with the cost per person is given as
N∝ 1/C
Introducing constant of proportionality, k, we have that
N= K/C
such that when there were 4 people the cost per person was $57, K would be
N= K/C
4 = K /57
k= 57 X 4
k=228
Step 2
Therefore If the number of people changed to 12, cost per person would be
N= K/C
12= 228 / C
C= 228/12
C= 19
The new cost per person= $19 when there are 12 people
The diameter of a pizza is 14 inches what is the circumference of the pizza use 3.14
Answer:
43.96 in.
Step-by-step explanation:
A pizza is found in shape. Therefore, we would apply the formula for the circumference of a circle to find the circumference of the pizza.
Circumference = 2πr
r = ½ of diameter = ½*14 = 7 in.
π = 3.14
Circumference = 2*3.14*7
Circumference of the pizza = 43.96 in.

Cards numbered 500 through 799 are placed into a box. How many of the cards satisfy both of the conditions shown below?
. The first digt of the three-digit number on the card is odd.
• The three-digit number on the card is divisible by 6.
A
SO
33
C
25
12
First
Answer:
33
Step-by-step explanation:
Given that :
Card numbered from: 500 - 799
The required number of values must meet both conditions 1 and 2
Condition 1 : first of the 3 digits is odd :
500 - 599 = 100
700 - 799 = 100
(100 + 100) = 200 cards
Condition 2: three digits is divisible by 6
{500 - 599} and {700 - 799}
The numbers divisible by 6 are 33

An airplane is currently flying at an altitude of 37,000 feet. The airplane is scheduled to land at an airport 100 miles
away. Find the average angle at which the airplane must descend for landing. Round your answer to the nearest
degree.
Answer:
4degrees
Step-by-step explanation:
Given the following
Height of the airplane = 37000feet
distance covered on landing = 100miles = 100(5280)
distance covered on landing = 528,000feet
Using the SOH CAH TOA
sin theta = opposite/hyp
sin theta = 37000/528000
sin theta = 37/528
theta = arcsin (37/528)
theta = 4 degrees
Hence average angle at which the airplane must descend for landing is 4degrees
