(7x + 3)

Mathematics
1 answer:
padilas [110]3 years ago
3 0

Answer:

D or 6

Step-by-step explanation:

Angle G is bisected if FGHI is a square. That being the case

7x + 3 = 45          Subtract 3 from both sides

7x = 45 - 3          Combine

7x = 42               Divide by 7

7x/7 = 42/7

x =  6

When Jim went to The Supreme Steak House, he had a meal costing $32.92. If the tax on the meal was 5%, what was the total cost o
sp2606 [1]
Take the total cost of the meal ($32.92) and multiply it by 5% (.05)
once you multiply those together you get how much tax is which is $1.65 (rounded up from 1.646)
now add that to your total and you get $34.57.

an employess new salary is 28,140 after getting 5% raise what was salary before increase _and what was last years salary _?
jonny [76]
He got a 5% raise, so 28,140 is 105% of what it used to be.

105% means 1.05

(1.05) x (salary before increase) = 28,140

Divide each side by 1.05 :

Salary before increase = 28,140 / 1.05 = <u>26,800</u> .

The rest of the question is nonsense. The salary
before increase IS last year's salary.

The sum of half of a number and 8 less<br> than the number is 25. Find the number.
LuckyWell [14K]

Answer:

The number is 22

Step-by-step explanation:

let x = the number

\frac{1}{2} x  + x - 8 = 25 \\  \frac{1}{2} x + x  - 8 + 8 = 25 + 8 \\  \frac{1}{2} x + x = 33 \\ factor   \: out\: x \: on \: the \: left \\ x( \frac{1}{2}  + 1) = 33 \\ divide \: both \: sides \: by \:  \frac{1}{2}   + 1 \\  \frac{x( \frac{1}{2} + 1) }{ \frac{1}{2}  + 1}  =  \frac{33}{ \frac{1}{2}  + 1}  \\ x =  \frac{33}{ \frac{3}{2} }  \\ x =  \frac{66}{3}  \\ x = 22

How many five-digit integers (integers from 10,000 through 99,999) are divisible by 5?
lukranit [14]
Okay to solve this problem you would simply do this solution. It took me a minute, haven't had to do integers in a while. :D

From 10,000 to 99,999 the numbers divisible by 5 ends in 0 or 5.
The first (most significant) digit can be any of nine from 1 to 9.
The 2nd digit can be any of 10.
The 3rd digit can be any of 10.
The 4th digit can be any of 10.
The 5th digit can be either of 2.

<span>That's 9(10)(10)(10)2=18,000
</span>
I hope this helps.
