Answer:
3x²-10x+8
Step-by-step explanation:
To simplify the expression we need to multiply each term in the first bracket with the expression in the second bracket.
x(3x-4)-2(3x-4)
3x²-4x-6x+8
Executing the operations to give a quadratic expression we get:
3x²-10x+8
The simplified expression is therefore
3x²-10x+8
Answer:
The number of strawberry baskets sold was 44
Step-by-step explanation:
Let
x ----> the number of strawberry baskets sold
y ---> the number of raspberries baskets sold
we know that
In one morning, Katya sells 96 baskets for $644
so
----> equation A
---> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (44.52)
see the attached figure
therefore
The number of strawberry baskets sold was 44 and the number of raspberries baskets sold was 52

Answer:
45.8 mph
Step-by-step explanation:
(speed of each hour between 2 and 4) 37.5 + 50.0 + 50.0= 137.5
(divided by amount of numbers added, which in this case is 3)
137.5 ÷ 3= 45.833333 (45.8 when rounded)
hope this helps
Answer:
-10.4
Step-by-step explanation:
Assume that the number we are looking for is x.
Now, we want to get 10 times the sum of half the number and 6 and equate this expression to 8. Then we can solve for x
step by step
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8
Now solve for x
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4
