Answer:
Make an eqaution from here.
Let’s make evening 2 “x”
So the first evening has 9 less then the secon evening so…
x-9
Of course theres the second evening (x).
X-9+x
Then the third evening has 4 times as much as the second meeting so…
x-9+x+4x
And when solved, it has to equal 105.
So solve from here.
Combine like terms.
6x-9=105
Isolate
6x=114
x= 19
First evening is 9 less then 19, so 10.
The second evening was 19 calls.
The third evening was 4 times the second evening so, 19*4= 76
1st night = 10
2nd night= 19 calls
Thrid night= 76 calls
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaah!!!!!!!!!!!!!!
Answer:
Answer:
x= 29/11 or y= 25/11
Step-by-step explanation:
2x - y= 3 ...........equation 1
x + 5y= 14 ............equation 2
Make x the subject of the formula in equation 2
x= 14 - 5y ..............equation 3
Substitute x=14 - 5y in equation 1
2(14- 5y) - y=3
28 - 10y - y=3
Collect like terms
-10y - y=3 - 28
-11y= -25
divide both sides by coefficient of y
-11y/-11 = -25/-11
y= 25/11
Substitute y= 25/11 in equation 3
x=14 - 5(25/11)
x= 14 - 125/11
x= 29/11
Step-by-step explanation:
<span>Safarina has 34 out of 99 hits.
Find her battling average.
=> 34 hits
=> 99 hits in all
x = value of percentage
=> 34 = x * 99
=> 34 = 99x
Now, let’s divide both sides with 99
=> 34 / 99 = 99x / 99
=> 0.3434343 = x (0.343434… is a repeating decimals, so need to round off to the nearest hundreds)
=> 0.34 = 34/100
Thus, the percentage of Sarafina’s hit is 34%</span>
Answer:
1.) The quotient of a number and 2 = x ÷ 2
2.) A number decreased by 2 = x - 2
3.) 2 times a number = 2x
4.) 2 increased by a number = 2 + x
Step-by-step explanation:
Let's look for key words hidden in these sentences:
1.) The <u>quotient</u> of a number and 2 = The word quotient refers to division
2.) A number <u>decreased</u> by 2 = The word decreased refers to subtraction
3.) 2 <u>times</u> a number = the word times refers to multiplication
4.) 2 <u>increased</u> by a number = the word increased refers to addition
Hope this helps!
