Hey there!!
The basic slope-intercept formula :
y = mx+ b where ' m ' is the slope and ' b ' is the slope-intercept.
Given equation : 7x - 2y = 8
We will have to isolate the ' y '
... 7x - 2y = 8
Subtract 7x on both sides
... -2y = -7x + 8
Divide by - 2 on both sides
... y = ( 7x / 2 ) - 4
Hence,
slope = 7/2 = 3.5
y-intercept = ( 0 , -4 )
Hope it helps!!
Answer:
96oz = 6 pounds
Step-by-step explanation:
96 divided by 16 = 6 pounds
Answer:
Kindly check explanation
Step-by-step explanation:
Kilogram of flour needed to complete holiday order is atleast 175kg
Number of kilograms available = 34kg
Flour comes in bags each contain 23kg of flour
He wants to buy the smallest number of bags as possible and get the amount of flour he needs.
Let F = number of bags of flours Sergei needs to buy
F = (total number of kilograms needed - number of kilograms available) / kilograms per bag
F = (≥ 175 - 34) / 23
F = ≥ 141 / 23 = ≥ 6.1304347
Since flour is purchased per bag, the smallest number of bags he can possibly buy and still get the amount of flour he need = 7 bags
A+c=100
3a+2c=275, from the first c=100-a making the 2nd equation become:
3a+2(100-a)=275 perform indicated multiplication on left side
3a+200-2a=275 combine like terms on left side
a+200=275, subtract 200 from both sides
a=75, and since c=100-a
c=100=75=25
So the answer is D. 25 children and 75 adults
Equation 1: a+c=100
Equation 2: 3a+2c=275
