Answer:
Total amount Silas and Raja has at first = $252
Step-by-step explanation:
Let,
Amount Silas had = x
Amount Raja had = y
According to given statement;
x = 3y Eqn 1
x-84 = y+42 Eqn 2
Putting value of x from Eqn 1 in Eqn 2
3y - 84 = y+42
3y-y = 42+84
2y = 126
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{126}{2}\\y=63[/tex]
Putting y = 63 in Eqn 1
x = 63(3)
x = 189
Total amount they had = 189 + 63 = $252
Hence,
Total amount Silas and Raja has at first = $252
The amount they have altogether at first is $252
Let
Raja money = x
Silas had 3 times as much money as Raja. Therefore, Silas money is as follows:
3xSilas spent $84 of his money to buy a birthday gift for his grandma. Therefore, he has the following amount:
3x - 84Raja was awarded $42 for winning a competition. Therefore, Raja amount is as follows;
x + 42In the end, they had the same amount of money. Therefore,
3x - 84 = x + 423x - 84 = x + 42
3x - x = 42 + 84
2x = 126
x = 126 / 2
x = 63
Total amount(at first):x + 3x = 63 + 3(63) = $252learn more on equation here: https://brainly.com/question/228711?referrer=searchResults

Step-by-step explanation:
Answer:
i think its 3
Step-by-step explanation:
convert 8.132132132... to a rational expression in the form of a fraction
Let x = 8.132132132... .
Then 1000x = 8132.132132132... .
Subtracting x from 1000x eliminates the fractional part, leaving you
999x = 8132 - 8 = 8124
Then
x = 8124/999 = 2708/333

Answer:
200,000
Step-by-step explanation:
Step one:
given data
We are given that 15% of a non-profits Donations is about 30,000
Required
The amount in total received in donation
Step two:
Let the total donation be x
so
15/100*x= 30000
solve for x
0.15*x= 30000
divide both sides by 0.15
x= 30000/0.15
x=200,000
Hence the total donation is about 200000

h(x)=-x^2+10x-16 What is the height of the ball at the time it is thrown
Answer:
0m
Step-by-step explanation:
Before the ball is thrown, it is at the ground level. At the ground level, the height is zero. Substitute h = 0 into the equation;
h(x)=-x^2+10x-16
0=-x^2+10x-16
x^2-10x+16 = 0
Factorize
x^2-8x-2x+16 = 0
x(x-8) - 2 (x-8) = 0
x-2 = 0 and x - 8 = 0
x = 2 and 8
At x = 2
h(2) = -2^2 + 10(2) - 16
h(2) = -4 + 4
h(2) = 0
Hence the height of the ball at the time it is thrown is 0m

full. Then 63cm3 of orange juice is poured in.
The glass is now
5
-
8
full.
What is the total volume of the glass?
Step-by-step explanation:
x=volume of the glass
(1/3)x+63=(5/8)x
63=(5/8)x-(1/3)x
63=(15/24)x-(8/24)x
63=(7/24)x
multiply both sides by 24/7
(24/7)(63)=(24/7)(7/24)x
216=x
216 cm3 is the volume (answer)
1/3 of 216 is 72
72+63=135
135/216=0.625=5/8
what times what equals 3/8
Answer:
1/8 * 3
Step-by-step explanation:
1/8*3 means the numerator gets multiplied by 3 so we get (1*3)/8 which is 3/8
The equivalent value of the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be p
Let the second fraction be q
Now , A = pq
when the value of p = 3/4
And , when the value of q = 1/2
On simplifying the equation , we get
3/8 = ( 3/4 ) ( 1/2 )
So , the left hand side of the equation is equated to the right hand side by the value of ( 3/4 ) ( 1/2 )
A = ( 3/4 ) ( 1/2 )
A = 3/8
Therefore , the value of A = 3/8 = ( 3/4 ) ( 1/2 )
Hence , the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )

easy vector problem! show work/explain please :)
Answer:
Step-by-step explanation:
a = 2i + 3j + zk
b = xi + 1j + 4k
Given a X b = 6i -14j +5k
a X b = | i j k|
|2 3 z|
|x 1 4|
a X b = i(12-z) - j(8 - xz) + k(2-3x) = 6i -14j +5k
equate the coefficients of i , j and k
12- z = 6; implies z = 6
8 - xz = -14 implies 8 - 6x = -14
2-3x = 5 implies 2 - 3x = 5 implies x = -1
