You divide $4.20 by a dozen (12).
This gives you $0.35 per donut

For the next one, you divide $7 by 4 to get the individual price. This gives you $1.75 per cookie, but you still need to multiply it by 9 to get the total price of 9 cookies.
When you multiply 9 by 1.75, your final answer for the second one is $15.75.
Hope this helps :)

If k = -3 what is the value of k + (2k - 10) ? A. –19 B. –7 C. 1 D. –14

gladu [14]

Answer:

Step-by-step explanation:

We have the expression $k+(2k-10)$

We want to find the value when k is -3. So, substitute -3 for k and evaluate:

$\Rightarrow (-3)+(2(-3)-10)$

Multiply:

$=-3+(-6-10)$

Subtract:

$=-3+(-16)$

Add:

$=-19$

Therefore, our answer is A.

Jamal wrote that 9 – 8.4 = 6

iragen [17]

Answer:

See below

Step-by-step explanation:

9 and 8.4 are less than 1 apart, so 9-8.4 must be less than 1. The actual difference is 9-8.4=0.6 which verifies that our answers are true since 0.6<1.
