five more than two-thirds of a number is 12 . what is the number ?
Answer:
[tex]x=7\frac{3}{2}[/tex]
Step-by-step explanation:
Suppose the number is x
[tex]\frac{2}{3}x+5=12[/tex]
[tex]\frac{2}{3}x=12-5[/tex]
[tex]x=7\frac{3}{2}[/tex]
Divide these fractions

Soos is spending money at an average rate of $5 per day. After 9 days, he has $25 left.
How much money did Soos have at the beginning (on day 0)?
y - 5= 9(x - 25)
Answer:
$70
Step-by-step explanation:
According to the problem, calculation of given data are as follows:
Spending money at rate = $5 per day
After 9 days money left = $25
We can calculate the money on day 0 by using following formula,
y = mx + b
Here, y = money left after 9 days
m = rate of spending money
x = number of days
b = money on day 0
So, by putting value, we get
$25 = (-5 × 9 ) + b
b = $25 + $45
= $70

1.24 * 0.15 = 0.0186
As you can see, the numbers are the same, but the order of the decimal is different.
Since the order of the decimal is different, so will the answer.
1,860 and 0.0186 do have the same numbers in them, but since the decimal is located in different spots, then the answer will be different with different values.
You might not see the decimal in 1,860, but it is after the 0.....
1,860.0 ( same thing just added a decimal, but it is the same value)
Hope this helped!

perpendicular(p) = 3
base(b)= 9
now
tan x = p/b
tan x = 3 / 9
tan x = 1 / 3
x = tan ^-1( 1/3)

Step-by-step explanation:
5x−4y=34
−x+8y=22
elimination
Answer:
The solution to the system of equations is:
[tex]x=10,\:y=4[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}[/tex]
Multiply -x+8y=22 by 5: -5x+40y=110
[tex]\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}[/tex]
so adding the equations
[tex]-5x+40y=110[/tex]
[tex]+[/tex]
[tex]\underline{5x-4y=34}[/tex]
[tex]36y=144[/tex]
solve 36y = 144 for y:
[tex]36y=144[/tex]
divide both sides by 36
[tex]\frac{36y}{36}=\frac{144}{36}[/tex]
Simplify
[tex]y=4[/tex]
For 5x-4y=34 plug in y=4
[tex]5x-4\cdot \:4=34[/tex]
[tex]5x-16=34[/tex]
Add 16 to both sides
[tex]5x-16+16=34+16[/tex]
Simplify
[tex]5x=50[/tex]
Divide both sides by 5
[tex]\frac{5x}{5}=\frac{50}{5}[/tex]
Simplify
[tex]x=10[/tex]
Therefore, the solution to the system of equations is:
[tex]x=10,\:y=4[/tex]
