50000 x (10.6/2=5.3%)=50000 x 5.3/100. =2650. Then ad to 50000+2650=$5,2650 .00
Rein is right
-2(-y - 3) +4y = 2y +6+4y =6y + 6

5x /8 =20. 5x = 160. X =32 . .she bought 32 apples
2x (2x) =0. 2x =0. X =0
You are right reiny
I knw it. . . X ^2 (9x^2 -24x +4 ) =0. . X^2(3x-4)(3x -4) =0. . 3x -4 =0/x^2. 3x-4 =0. . X =4/3 twice
I m good at this but mary you gotta give ur self a chance the ansas are 1.a 2.d 3.b 4.c
5/20 x 100 =25%
The percentage off people wearing glasses are 25 -3 .=22 22/25 x 100. = 88%. And 3/25 x 100=12%
2a + d = 4 a + 9d =19. . Solve simultaneously ,a=1 .,d =2. Find 2a + 9d =2 +18 =20
10a + 45d =50 .a +4d = 3a + 3d =a =d/2 10(d/2) + 45d = 50. .d=1 . a=1/2. . . S20=20(1/2) +190(1) =200. . Ans =200
My brother is jUst entering dat why
Steve dat nt it . Try this one . .a/2.5^n -1.0 . To check maybe it goes along wit d ques. And is this ogonna
Steve got it but it did nt reach quarter of d workings
S15 =510
Correct
a + 2d =14, a + 8d = -1. Solve simultaneously. . . .a =19 . .d =-5/2. .0. The sequence is . 19,16.5,14,11.5
Happy birthday to you long life and prosperity.
Answer is 2320.843
Ans 15 /100 x 500 =75 . 500-75 =$425. The discount is $425
The amount of discount emily wil pay is 6 /100 x 20000. =1200. 20000 -1200=18800 . In 8 years. . Discount rate by compoud interest =do it your self
Shredder is correct .steve is not correct
Area of square =36
Yeah
2(l+b) =72 .2 (l +8)=72. 2l + 16 =72 . 2l =56 . L =28
Yeah
X^2 + 5x + 6 = 0; factorize X^2 + 2x + 3x + 6 = 0. X (x + 2) + 3(x + 2)= 0. (X + 2) + (x + 3) = 0. X + 2 = 0, x + 3 = 0. Collect like terms. X = -2, x = -3. therefore, x = -2 or -3
. .area of triangle = 1/2 bh . Height of sail . = 6+b. . .20 = 1/2 x b x (6 + b) . 20= 1/2 x 6b + b^2. 6b +b^2 =40. . b^2 + 6b - 40. . (b+10)(b - 4). b=-10 or 4 and h =6 + b . Height of sail =6 +4 =10. . Height of sail =10 meters

I can help . . . D varies t^2 . Which means d=kt^2. 500 =10^2 x k . 500 = 100k. K =constant =5 . The law goes lyk dis. D =5t . But we must nt neglect aceleration due to gravity=10ms^2. D =5 x 9 x 10=450m. . . Ansa =450* coz when 10s =500m . 9s = 450m
d =4.90 x 4.2 ^2 .=86.4 aprox 86 m
U tried bt itz wrong . .ansa iz a . . 6m - 5 =m . Colect lyk terms . 6m -m =5 . 5m =5 . Then m =1 .
All are correct u are realy good
Represent 2 ^ x with p and 3 ^y with q . .p + q =17. And 2^ x+2 = 2^x X 2^2 =4p + 3 ^ y+1 =3^y x 3^1 =3q. . Solve simultaneously. P +q=17. . 4p + 3q = 5. . . . q =63 . P = -46
. Using x^2 +(p+q)x +pq new equatin is x^2 -3p -7/2 =2x^2 -6x - 7. . But ur ques is nt clear
Just folow this step and u get ur ansa if u hav a ques lyk x - y =0 eqn1 ,x + y =4.eqn2 . Firs t solv for x . X = 0 + y=y eqn 3 . .then substitute x in eqn 2 . . 0 + y + y =4 . 2y =4. y =2 . . . Sub y in eqn 3 x = y then x=2,y=2
Wrong
I dnt get ur ques is that sign raise to power
Afta arangin it in d form of ax +by=c . . 0.2x =2x/10 2x/10 - y=0.3 Afta doin Lcm 2x -10y divided by 10 =0.3 . . 2x -10y =0.3 x 10 =3 . Therefore ans = 2x -10y =3
Steve dnt be harsh it was jxt a ques . . (Eye wink) the easy way goes lyk dis first fynd lcm . Cros multiply then colect like term to d right side. Soln. -2x/5 -3=5y. .lcm is 15 it b coms. -2x -15 =5y den colet lyk term 2x +15=5y or 2x +5y =-15
Sorry there is mistake d quest didn't say in 20 yrs tym xo . D ansa is dat if sam is 20 yr tom wil be 20 x 3 =60yr
Wrong . . .the bro is 5 + 20 =25 in 20 yrs tym . . Hs bro is 3 times is age =3 x 25 =75. . Which means when he is 25 ys hs bro wil be 75 yrs
I don't agree with dat ansa . . |tanx|=1 . . X =tan inverse of 1 which is 45 . .the ansa 4 x is 45
10x +20y =780. X + y =54 . Solve simultaneously x=30 and y=24. . . If u wana knw hw many gold coin7 itz lyk dis 10 x 30=$300and 20 x 24 =$480
