1 answer:
ra1l [238]3 years ago
6 0

Answer:

a. m = Vd

b. 6.012g

Step-by-step explanation:

a.  you need to rearrange the equation so that you're solving for m. you can do so by multiplying both sides by V so you end up with

Vd = m or m = Vd (i prefer writing it this was purely cause it looks better)

b. now, you can plug in each value into the new equation so you get

5.01g/cm3 x 1.2 cm3 = m

from here you just multiply as normal

If 6 times a number is added to -4, the result is 10 times the number. Find the number.
andrew11 [14]

the number is - 1

let the number be n then 6 times the number is 6n and added to -4 is

- 4 + 6n = 10n ( equal to 10 times the number )

subtract 6n from both sides

- 4 = 4n ( divide both sides by 4 )

\frac{-4}{4} = n , hence n = - 1

Seven cakes cost £2.10 how much do 10 cakes cost
Len [333]
Ten cakes costs $2.19 (pounds, but I don't have a pounds symbol on my computer) because if you divide $2.10 by seven you get $0.3, and if you add 3×0.3 (because we have seven, and we need to add three more to get ten) we get $0.9.
 
0.9+2.10=2.19

Write x2 - 8x - 3 in vertex form.
crimeas [40]
Vertex form:

y = a(x - h)² + k

I have not learned this stuff yet, but by using online calculators, I can determine that the vertex form is:

Y = (x - 4)² - 19

I believe so :/

if you divide a positive number by 12, the answer would be less than the original number? always, sometimes, or never​
elena55 [62]

Answer:

Always

Step-by-step explanation:

The rules for positive numbers is that addition and multiplication makes numbers larger. Subtraction and division makes numbers smaller.

Since 12 is a positive number, the result of dividing a positive number by 12 will make it smaller.
