Answer:
A=45 b=110
Step-by-step explanation:
I used a calc
Answer:
A=135 b=200
Step-by-step explanation:
135+200+25=360
X+(x+65) +25=360
Subtract 25 from both sides
X+ (x+65)=335
Combine like terms
2x +65=335
Subtract 65 from both sides
2x =270
Divide by 2
X=135
To get b you just do 135+65=200

and y, the number of pounds of each type of chocolate. write two equations and solve using elimination
!!!!PLEASE HELP!!!!
Answers
Answer:
5 pounds eachStep-by-step explanation:
Required equations:
x + y = 103.50x + 4.30y = 39Substitute x in the second equation:
x = 10 - ySolve for y:
3.5(10 - y) + 4.3y = 3935 - 3.5y + 4.3y = 390.8y = 4y = 4/0.8y = 5Then
x = 10 - 5 = 55 pounds each
The cost of 3 pounds of grapes is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x?
Answers
Answer:
$2.19
Step-by-step explanation:
Given that :
Cost of 3 pounds of grape = $6.57
Cost in dollars = y ; number of pounds = x
Cost in dollars α number of pounds
Cost in dollars = k * number of pounds
k = constant of proportionality
$6.57 = k * 3
$6.57 = 3k
Divide both sides by 3
6.57 / 3 = 3k/ 3
2.19 = k
k = $2.19

How do you solve for the slope of a graph that isn't straight? How would I solve the slope for this?
Answers
9514 1404 393
Answer:
use the slope formula
Step-by-step explanation:
Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.
m = (y2 -y1)/(x2 -x1)
For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...
(hours, miles) = (1, 25) and (2, 75)
The corresponding slope on that interval is ...
m = (75 -25)/(2 -1) = 50 . . . . miles per hour
__
You can identify four (4) regions on this graph in which the slope is constant:
(0, 1) . . . slope is 25 mph
(1, 2) . . . slope is 50 mph, as computed above
(2, 3) . . . slope is 0 (the rider has stopped)
(3, 5) . . . slope is 25 mph
Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

Factorise y2 + 2y - 24
Answers
Answer:
(y + 6)(y - 4)
Step-by-step explanation:
Factor the following:
[tex] \longrightarrow [/tex] y² + 2y - 24
The factors of -24 that sum to 2 are 6 and -4.
So,
[tex] \longrightarrow [/tex] y² + (6 - 4)y -24
[tex] \longrightarrow [/tex] y² + 6y - 4y - 24
[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)
[tex] \longrightarrow [/tex] (y + 6)(y - 4)
Answer:
( y-4) ( y+6)
Step-by-step explanation:
= y^2 + ( 6 - 4)y - 24
= y^2 + 6y - 4y - 24
= y( y + 6) - 4(y + 6)
= ( y - 4 ) ( y + 6)

3x = 129
X = 43
Answer:
x = 43
Step-by-step explanation:
lines were parallel, then 143 would have to congruent to the vertical angle of 3x + 14
this means that 143 would have to be congruent to 3x + 14
so we can set the equation to 3x + 14 = 143
subtract 14 from both sides: 3x = 129
divide both sides by 3: x = 43
