solve each equation by factoring
[tex]8k^2-26k+20=0[/tex]
please show work!
Answer:
k=2 or 5/4
Step-by-step explanation:
8k^2-26k+20=0
2(4k²-13k+10)=0
(4k²-13k+10)=0/2
4k²-8k-5k+10=0
4k(k-2)-5(k-2)=0
(k-2)(4k-5)=0
either.
k=2
or
k=5/4

bob has 8 pieces of square index cards that each measures 8 inches per side. Using a pair of
scissors, he cuts each piece in half (so the resulting size is 8” x 4”) and then places all the
resulting card pieces in a new stack. If he repeats this procedure 4 more times, how many
pieces of card stock will he have and what will be the measure of each piece? (Note: All
cuts will be made along the longer edge of the piece if the piece of index card is not square.)

Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week. Rewrite the inequality from in slope-intercept form
Answer:
18x ≥ 160
Step-by-step explanation:
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week.
Let the number of hours = x
At least = Greater than or equal to
Slope intercept form
= y = mx + c
y = $160
Hence
10x + 8x ≥ 160
18x ≥ 160

20 divided by 2 1/3 = 8.57
8 batches is the answer.
Answer:
Actually, 20 divided by 2 1/3 equals 8.57 repeating (8.571428...), which can be rounded to 8.57 to two decimal places.
To see why, we can convert the mixed number 2 1/3 to an improper fraction:
2 1/3 = (2 * 3 + 1) / 3 = 7/3
Then, we can rewrite the division as a fraction and simplify:
20 / (7/3) = 20 * (3/7) = 60/7 = 8.571428...
So, 20 divided by 2 1/3 is approximately 8.57.
