The first thing that you do when simplifying an expression with the variable’s values known is to distribute the values. EXAMPLE:
3(7x+9)+6(-16x-40); distribute:
21x+27-96x-240; combine like terms:
(21x+(-96x))+(27+(-240))——-> -75x-213; now plug in the values and solve: -75(6)-213=-663
Answer:
84%
Step-by-step explanation:
In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...
19oz + 9oz + 7oz = 35oz
Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.
35oz / 19oz = 1.84
1.84 - 1 = 0.84
0.84 * 100 = 84%
Finally, we can see that the puppy had an 84% increase since the first visit.
Answer:
answer =-1.
Step-by-step explanation:
(i)write the question nicely again.
(ii) substitute the ltter with the value that is given.
(iii)u gonna use BEDMAS RULE TO SOLVE.
$4.08/16 ounces: $0.255
$4.50/18 ounces: $0.25
$5.39/22 ounces: $0.245
The best buy would be $4.50 for an 18-ounce box of cereal.
We know that 1 foot = 12 inches. 4 feet = 48 inches. So, we have 48 : 45 inches. Right?
