Twice a number is equal to 35more than 7 times the number .find the number
Answer:
the number is -7
Step-by-step explanation:
so the equation looks like this
[tex]2x= 35+7x\\\\[/tex]
twice the number equals 35 more than 7 times the number
now solver for x
[tex]2x-7x = 35\\\\-5x = 35\\\\x = -7[/tex]
and the number is -7
[tex]2(-7) = 35+7(-7)\\\\-14 = 35-49\\\\-14 =-14[/tex]

The Slow Fix auto shop charges $28 for parts and $48 per hour of labor. The We Work Cheaper auto shop charges $59 for parts and $44.90 per hour of labor. For how many hours will the total cost the same for both auto shops?
Answer: 10 hours
Step-by-step explanation:
Given
Slow fix auto charge $28 for parts and $48 per hour of labor
We work charge $59 for parts and $44.90 per hour of labor
Suppose both works for x hours
Cost of Slow fix= [tex]\$(28+48x)[/tex]
Cost of We work= [tex]\$(59+44.90x)[/tex]
When these costs are the same
[tex]28+48x=59+44.90x\\3.1x=31\\x=10\ hours[/tex]

Trisha opened a savings account and deposited one-hundred as principal. The account earns 12% interest, compounded annually. What is the balance after 3 years?
Answer: $140.49
Step-by-step explanation:
Trisha opened an account and deposited $100.
The account earns compound interest of 12% yearly and will be on for 3 years.
The formula for compound interest is:
= Principal * ( 1 + rate) ^ time period
= 100 * (1 + 12%)³
= $140.49

∆JKL is an isosceles triangle with vertex angle K. Find the values of x and y if JK = 8x, KL = 13x – 15, m∠KJL=(5y-3)°, and m∠JKL=76°.
Answer:
The values of x and y are x = 3 and y = 11
Step-by-step explanation:
The isosceles triangle has two equal sides in length, and its base angles are equal in measures
In ΔJKL
∵ ΔJKL is an isosceles triangle with vertex K
→ That means the equal sides are JK and KL
∴ JK = KL
∵ JK = 8x and KL = 13x - 15
→ Equate them
∴ 13x - 15 = 8x
→ Add 15 to both sides
∵ 13x - 15 + 15 = 8x + 15
∴ 13x = 8x + 15
→ Subtract 8x from both sides
∵ 13x - 8x = 8x - 8x + 15
∴ 5x = 15
→ Divide both sides by 5 to find x
∴ x = 3
∵ K is the vertex of the ΔJKL
∴ ∠KJL and ∠KLJ are the base angles
∵ The base angles are equal in measures
∴ m∠KJL = m∠KLJ
∵ m∠KJL = 5y - 3
∴ m∠KLJ = 5y - 3
∵ The sum of the measures of the angles of a Δ is 180°
∴ m∠KJL + m∠KLJ + m∠JKL = 180°
∵ m∠JKL = 76°
→ Substitute the measures of the 3 angles in the equation
∴ 5y - 3 + 5y - 3 + 76 = 180
→ Add the like terms on the left side
∵ (5y + 5y) + (76 - 3 - 3) = 180
∴10y + 70 =180
→ Subtract 70 from both sides
∵ 10y + 70 - 70 = 180 - 70
∴ 10y = 110
→ Divide both sides by 10 to find y
∴ y = 11
∴ The values of x and y are x = 3 and y = 11

Answer:
4p + 2g
2p + 1g
Step-by-step explanation:
p = price of each pool pass for 1 person
g = price of gym membership for 1 person
Answer:
Step-by-step explanation:
Given in the question:
a) A family paid $96 for 4 pool passes and 2 gym memberships.
b)Later that day , an individual bought pool passes for herself and 2 of her friends, and 1 gym membership for her. She paid $60
Let's write the system of equation for each purchases that happened in the scenario.
Let,
P= Price of each pool passes
G= Price of each gym membership
We get,
a) A family paid $96 for 4 pool passes and 2 gym memberships:
[tex]4P+2G=96[/tex]
b)Later that day , an individual bought pool passes for herself and 2 of her friends, and 1 gym membership for her . She paid $60:
[tex]3P+1G=60\\[/tex]
Therefore, the equation generated in the scenario were:
[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]
Where,
P= Price of each pool passes
G= Price of each gym membership

If you flip a coin and roll a 666-sided die, what is the probability that you will flip a heads and roll a 2?
Answer: [tex]\dfrac1{12}[/tex]
Step-by-step explanation:
Outcomes for tossing a coin =2 [tail and head]
Outcomes of rolling a 6-sided die =6
Total outcomes for rolling both = 2 x 6 = 12
Favorable outcomes for getting a head and 2 on die = 1
Probability = [tex]\dfrac{favorable\ outcome}{Total\ outcomes}[/tex]
Now , the probability that you will flip a heads and roll a 2 [tex]=\dfrac1{12}[/tex]
Hence, the required probability = [tex]\dfrac1{12}[/tex]

10% of the passengers on a fly with us airlines flight are in first class. If there are 40 passengers in first class, how many total passengers are on the flight
Answer:
400 passengers
Step-by-step explanation:
To solve the problem, a proportion would be best!
First, let's set up the left side of the proportion. Percents, when used in parts, are always part of 100%, making 100% a whole. We'll use both 10% and 100% as our first fraction, which should look something like this:
[tex]\frac{10p}{100w}[/tex] (with p standing for part and w standing for the whole)
Next, let's set up the right side of our proportion. We'll use the 40 for our part and x for our whole since that is the number we are solving for. The proportion should now look like this:
[tex]\frac{10p}{100w} = \frac{40p}{x}[/tex]
To solve, just cross multiply and divide! Multiply 40 by 100 to give you 4,000. Next, divide 4,000 by the remaining 10 to give you a final answer of 400. If 40 passengers on the flight are in first class, then there are 400 total passengers. Hope this helps!
