Answer:
x = 9
Step-By-Step Explanation:
1. 3x + 5 + 6x + 4 = 90
2. 9x + 9 = 90
3. 9 + -9
4. 90 + -9
5. 9x = 81
6. x= 9 Substituting X:
3 X 9 + 5 = 27 + 5 = 32
6 X 9 + 4 = 54 + 4 = 58 58 + 32 = 90, so X = 9
Answer:
Step-by-step explanation:
The reason I say the answer above is wrong is because their answer equals up to a angle of 100 degrees however your angle is equaling up to 90 degrees. First off we know this angle is going to be 90 degrees right so we put it into the eqution:
=90
but we don't know what x is in order to solve the degrees that add up to 90, so since these equations add up to 90 we put them into the equation:
(3x + 5)+ (6x + 4) = 90
we then add all the numbers that have the same variables or are simply numbers in the equation
3x + 6x and 5 + 4 to get 9x + 9 = 90
we then subtract 9 from both sides (because what you do to one side you do to the other) to get 81
the equation now looks like this: 9x = 81 so now we divide 9 from both sides to get x = 9
Now how do we know if x is really 9 well we plug it into the equations (3x + 5) and (6x + 4) making them look like this (3(9) + 5) and (6(9) + 4)
and you get (3(9) + 5)= 32
(6(9) + 4)= 58
and when you add them together you get 90
32 + 58 = 90

Suppose a,b,c represent three positive whole numbers. if a+b=13 and b+c=22 and a+c=19 what is the value of c
Answers
Answer: C = 14
Step-by-step explanation: You can assume the A is less than B, and if you just go down in numbers such as A=6 and B=7 (To solve A + B = 13), you will eventually get to A=5 and B=8. If you do B = 8 + C = 14 ( That you get after subtracting 8 by 22 ) You should get 22, and to proof check it, you do A + C which is going to be 5 + 14 and you get 19 thus proving that C = 14.

Is it possible to improve your grade from a "d" to a "b"?
Answers
Answer: Of course it is possible if you try your hardest and study
Answer:
Depends
Step-by-step explanation:
Hello! This problem really depends on where you are in the grading period and how many grades are entered in relation to your grade. If you have a D but only have 2 grades then getting a B in the class should be relatively easy. However, if you have a D in a class that you have 15 graded assignments in it will be much harder to raise your grade to a B. Best thing to do is work at this early and try not to let your grade dip throughout the grading semester.
Hope this helps!

A certain fraction has the value 3/4. If its numerator is decreased by 7 and its denominator is increase by 4, the resulting fraction has the value 1/2. Find the original fraction
Answers
Answer:
n = 16 - 7
n = 9
Step-by-step explanation:
If the numerator of a fraction is increased by 3, the fraction becomes 3/4."
Cross multiply
4(n+3) = 3d
4n + 12 = 3d
"If the denominator is decreased by 7, the fraction becomes 1."
Cross multiply
1n = d - 7
n = (d-7)
In the 1st equation replace n with d-7
4(d-7) + 12 = 3d
4d - 28 + 12 = 3d
4d - 3d - 16 = 0
d = 16 is the denominator
then n = 16 - 7
n = 9
9/16 = the original equation

His brother Dillon began the summer with $345.00 and has decided that he will referee soccer games. He will make $45.00 per week. After how many weeks will Matthew and Dillon have the same amount of money?
Answers
the anwer is no matthew will not have the same amount of money
Answer: 3 weeks.
Step-by-step explanation: Matthew's pay goes up by $160 a week, so that's y=160x.
Dillon's pay is $45 a week, but started out with $345. So, that's y=45x+345.
So, they will have the same amount of money after 3 weeks.

Stealth Bank has deposits of $700 million. It holds reserves of $70 million and has purchased government bonds worth $215 million. The bank's loans have a market value of $490 million. What does Stealth Bank's net worth, or equity capital, equal?
Answers
Answer:
$75 million
Step-by-step explanation:
Given that:
Reserve value = $70 million
Purchased government bond = 215 million
Market value of loan = $490 million
Net worth :
Assets - liability
Assets = (Market value of loan + purchased government bond + reserve value)
(490 million + 215 million + 70 million)
275 million + 70 million
= $775 million
Liability = Deposits = $700 million
Net worth = ($775 - $700) million
Net worth = $75 million

a small airplane flies 1 015miles with an average speed of 290 mph. 1.75 hours after the plane leaves, a Boeing 747 leaves from the same point. Both planes arrive at the same time; what was the average speed of Boeing 747?
Answers
Answer:
The Boeing 747 had an average speed of 580 mph.
Step-by-step explanation:
Constant speed motion
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
From the equation above, we can solve for d:
d = v . t
And we can also solve it for t:
[tex]\displaystyle t=\frac{d}{v}[/tex]
The small airplane travels 1015 miles at a constant speed of v=290 miles/hour. The time it took to arrive its destiny was:
[tex]\displaystyle t=\frac{1015}{290}[/tex]
t = 3.5 hours
The Boeing 747 left from the same point 1.75 hours after the small plane and traveled the same distance. It needed a time t' = 3.5 - 1.75 = 1.75 hours, thus its speed must have been:
[tex]\displaystyle v=\frac{1015}{1.75}=580[/tex]
The Boeing 747 had an average speed of 580 mph.

tangent 68° = opposite / adjacent
opposite (wall height) = tan (68) * 4 feet

8) Eugene borrows $250 at a 4% annual interest rate. If he does not
make any payments, how much simple interest will he owe in 18 months?
A) $10
B) $15
C) $18
D) $20
Answers
Answer:
The simplest interest will be $15 ⇒ B
Step-by-step explanation:
The rule of the simple interest is I = Prt, where
P is the initial amountr is the rate in decimalt is the time∵ Eugene borrows $250 at a 4% annual interest rate
∴ P = 250
∴ r = 4% = 4 ÷ 100 = 0.04
∵ The time is 18 months
→ Change the time to year because the rate is annual
∵ 1 year = 12 months
∴ t = 18 ÷ 12 = 1.5 years
→ Substitute the values of P, r, and t in the rule above to find the interest
∵ I = 250 × 0.04 × 1.5
∴ I = 15
∴ The simplest interest will be $15

At the beginning of every gym class, Mr. Gordon leads the class in a warm-up. In today’s warm-up, the class does jumping jacks for 3 minute. Erin does 54 jumping jacks in that time. Mr. Gordon says the class will do jumping jacks 4 minutes tomorrow. If Erin does jumping jacks at the same rate tomorrow, how many will she she do.
Answers
Answer:
Erin will do 72 jumping jacks.
Step-by-step explanation:
We divide 54 by 3 to get Erin's per minute ratio
She gets 18 jumping jacks per minute
We then add that to 54 to get her rate if she did for 4 minutes instead
The answer is 72
hope this helped!
Erin will do 72 jumping jacks in 4 minutes.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, Erin does 54 jumping jacks in 3 minutes.
Therefore, mathematically:
3 minutes = 54 jumping jacks
1 minute = 18 jumping jacks
4 minutes = 72 jumping jacks
