Step-by-step explanation:
Answer:
a.9
b. ay=9
xy= 18
Step-by-step explanation:
a. xa=ay (since a is a midpoint that means xa and ay are the same amount).
3x=5x-6
subtract 5x from both sides
-2x=-6
inverse operations, so divide both sides by -2. (a negative divided by a negative is a positive)
x=3
so xa=3x. fill in x
3*3 is 9
b. fill in the x
5*3-6
5 times 3 is 15.
15-6=9
(also xa is 9 and they are congruent so both are 9)
ay= 9
add both sides to find xy
9+9=18
xy=18

Answer:
well let’s break this down
Let’s make type a coffee “a”
And type b coffee “b”
a is 4.35
b is 5.70
We knwo that b is twice as many as a
The total is 614.25
So we can do soemthing like this
4.35a+ (5.70b)2 = 614.25
Now solve
If we simplify its really
4.35a+11.40b =614.25
I like multiply by a 100 to get rid of decimals
435a+1140b=61425
Here we can go 2 ways
We can isoalte a or b
im gonna isloate b
so it would be (61425-435a)/1140 =b
Now we can use that as a subsitube to find a
Now we can just do this
435a +1140(61425-435a)/1140 = 61425
Pop it through an algebra calculator (just search up math pa..Pa and copy paste it, edit if needed) and then you’d get your answer
Answer:
M = 20
Step-by-step explanation:
Given that M is directly proportional to r³ then the equation relating them is
M = kr³ ← k is the constant of proportion
To find k use the condition when r = 4, M = 160, that is
160 = k × 4³ = 64k (divide both sides by 64 )
2.5 = k
M = 2.5r³ ← equation of proportion
When r = 2, then
M = 2.5 × 2³ = 2.5 × 8 = 20
