Answer:
4 - ( 3x - 8 ) = 21
break the bracket first ,it gives : 4 - 3x + 8 = 21
12 - 3x = 21
- 3x = 21 - 12
- 3x = 9
-x = 9/3
-x = 3
X = - 3
[ check if the answer is correct, put -3 instead of X in the above equation ! we get 4 - { 3(-3) - 8 } = 21
4 - { - 9 - 8 } = 21
4 - { - 17 } = 21
break the bracket, minus and minus will multiply and will become plus , so we have 4 + 17 = 21 , hence 21 = 21 ! therefore X = -3
1) BC intercept y at (2,1) (given)
2) The slope of AB ===> m= (-1 - 1)?(14 - 2) ===> m = - 1/6
2) the slope of BC that is perpendicular to AB is the inverse of (1/6) & change the sign, that is 6. To find the function y, apply the formula:
y-y1) = m(x-x1) ===> y-1 = 6(x-2) [the coordinate of B] ==> y= 12x - 11
3) if y= 13, replace y by 13 in the equation:
13 = 12x -11 ===>x = 2
Well im not to sure about this one loook it up
Answer:
Answer is 904
Refer below.
Step-by-step explanation:
5650 total,
And 4:1 which adds up and make 5. So,
5x = 5650
x=5650/5
x=1130
As pichard part is 4:1 so his part is 4 overall the money so,
Richard got 4x = 4 × 1130 = 4520
4520 now dividing in 6:3:1
10a = 4520
A= 452
Wife amount is 3a = 3 ×452 = 1356
Son is 1a so its,
Son = 452
Minus= 1356 -452 = 904
Wife got 904 more than son
