Answer:
Jamal :
have = $18
need = $46-$18
= $28
saves = $5 each week
= $5 × 5 weeks
= $25 ( not enough )
Samuel :
have = $10
need = $46 - $10
= $36
saves = $7 each week
= $7 × 5 weeks
= $35 ( not enough )
thus, both boys would not have enough money to pay for the trip .
Answer:
there are 10 tens in 105 with a remainder 5
Step-by-step explanation:
10 times 10 equals 100
Y = -2x - 2. Slope here is -2. A parallel line will have the same slope.
y = mx + b
slope(m) = -2
(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = -2(3) + b
4 = - 6 + b
4 + 6 = b
10 = b
so ur parallel equation is : y = -2x + 10
Quadratic formula is x = -b+ or- sq rt b^2-4ac / 2a
a=2 b=5 c=-3
-5 +or- sqrt 5^2-4(2)(-3) / 2(2)
-5 +or- sqrt 49/ 4
-5 + 7 /4 = 2/4 = 1/2
-5 - 7 /4 = -12/4 = -3
Factoring a*c is 2*-3 =-6
Factors of -6 that add to 5 are 6 and -1
Split 5x into +6x-1x
2x^2+6x-1x-3 and group
2x(x+3)-1(x+3)
(x+3)(2x-1)=0
x+3=0 gives x=-3
2x-1=0 gives x=1/2
