Answer:
d) 10
Step-by-step explanation:
x ÷ 
+ 8 = 13
substitute 10 for x:
⇒ 10 ÷ + 8 = 13
solve:
1) divide 10 by
⇒ 10 ÷ = 5
2) add 8 to 5
⇒ 8 + 5 = 13
The answer should be -40 + 16i
Answer:
180 mm
Step-by-step explanation:
height : cases
105 : 7
constant of proportionality = 105/7
height of 12 cases = 12 x 105/7 = 180 mm
This is going to require a good bit of division. I am going to turn the mixed fractions into improper fractions. Remember that to divide fractions, you take the 2nd fraction, flip it, and multiply.
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
7.69+2.5*4? two minusus equal an add but idk bout the rest
