Answer:
10x+4y+10z Hope I helped? :')
<u>Steps for answer!</u>
1. Expand by distributing terms.
6x+8y+10z+4(x-y)
2. Expand by distributing terms.
6x+8y+10z+4x-4y
3. Collect like terms.
(6x+4x)+(8y-4y)+10z
4. Simplify.
10x+4y+10z
Answer:
8(h)=x
Step-by-step explanation:
Matt earns 8 dollars for every hour he works. So you multiply the total numbers worked (h) by 8. That will give you the amount of money he's made(x) so the equation would be 8(h)=x
This is not possible. If you add an odd number of odd numbers, you will get an odd number. If you add an even number of odd numbers, you will get an even number. 5 is an odd number, but 32 is an even number, so therefore it is not possible.
A)
75% she knows for sure
Out of the remaining 25%, she has a 1/5 or 20% chance of getting it right. So,
1/4 x 1/5 x 100 = 5%
Total chance of getting a question right:
75 + 5 = 80%
b) If the total is 40, she can expect to get
80% x 40 = 32 questions correct.
