Answer:
x= -2
Step-by-step explanation:
Simplifying 5x + 45 = 35 Reorder the terms: 45 + 5x = 35 Solving 45 + 5x = 35 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-45' to each side of the equation. 45 + -45 + 5x = 35 + -45 Combine like terms: 45 + -45 = 0 0 + 5x = 35 + -45 5x = 35 + -45 Combine like terms: 35 + -45 = -10 5x = -10 Divide each side by '5'. x = -2 Simplifying x = -2

Anyone can help me with math for solving for a side in the right triangles for khan academy
Answer:
7.45
Step-by-step explanation:
We are given a right triangle with one side length known and an angle know so we can use some trigonometry.
You need to find the hypotenuse so you are going to use either sine or cosine.
Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,
cos(20) = 7/h
=>h = 7/cos(20)
=> 7.44924
=> 7.45

At this rate, how many pages can Henry write in 8 hours?
Answer:
Henry can write 13 pages in 8 hours.
Step-by-step explanation:
Rate: 5 pages in 3 hours (5/3 pages per hour)
To obtain the quantity of pages in 8 hours, we have to multiply the rate per hour by 8.
5/3 x 8 = 40/3= 13.34
Rounded to the nearest number, Henry can write 13 pages in 8 hours.

Answer:x=35 because if you add the terms then your equation would be 4x+40=180 because it’s a 180 degree line.
Step-by-step explanation:
Add parentheses to make true 36 / 9 - 3 = 6
36/ (9 - 3) = 6
Cause:
9 - 3 = 6
Then:
36/6 simplified equals 6
So, your answer is 36/(9 - 3) = 6
Hope it helps! Good luck friend! :3
Answer:
36 / (9 - 3) = 6
Step-by-step explanation:
If you put the parentheses around 9 - 3, that will give you 6. 36 divided by 6 = 6. Also, in PEMDAS, Parentheses comes first, so that is why the parentheses go there to make this true.
Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
Answer:
£3,692
Step-by-step explanation:
First four years
A = p(1 + r/n)^nt
P = £2350
r = 4.2% = 0.042
n = 1
t = 4
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Next 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692

5. James makes $15.50 per hour and works 40 hours a week. He pays 26% of his gross earnings in federal and state
taxes. He also saves 7.5% of his monthly gross income to put into savings. He is considering renting an apartment tha
will cost $1,400 per month. Based on his expenses, can he make the monthly payments?
9514 1404 393
Answer:
no
Step-by-step explanation:
On average, there are about 173 1/3 hours per month, so James's take-home pay will be about ...
($15.50/h)(173 1/3 h/mo)(1 -26%) = $1988.13
His proposed rental is about ...
1400/1988.13 · 100% = 70.4%
of his take-home pay.
Most financial planners would recommend the percentage be well below 50%. It is unlikely James can make his proposed monthly payments.
which is greater 21.798 or 217.98?
Answer:
217.98 is greater.
Step-by-step explanation:
Think about this way. Which is the larger number, 217 or 21? 217, of course. The decimal point only adds a small fraction of a number to the whole, so it doesn't affect the value that much.
I need help with my math assignment
Answer:
y = 3x + 11
Step-by-step explanation:
obviously since y is 11 when x is zero the constant term is 11.
Then use the other coordinates to find the cooefficent of x.
-4= c × -5 + 11
-4= -5c + 11
5c=15, c=3
Therefore the equation should be:
y= 3x + 11
