Answer:can yu help me get good at maths please
Step-by-step explanation:
Answer:
x > -1
Step-by-step explanation:
<u>Step 1: Distribute</u>
3(3x + 7) > 4 - 8(4 + 5x)
(3 * 3x) + (3 * 7) > 4 + (-8 * 4) + (-8 * 5x)
9x + 21 > 4 - 32 - 40x
<u>Step 2: Combine like terms</u>
9x + 21 > 4 - 32 - 40x
9x + 21 > -28 - 40x
<u>Step 3: Add 40x to both sides</u>
9x + 21 + 40x > -28 - 40x + 40x
49x + 21 > -28
<u>Step 4: Subtract 21 from both sides</u>
49x + 21 - 21 > -28 - 21
49x > -49
<u>Step 5: Divide both sides by 49</u>
49x / 49 > -49 / 49
<em>x > -1</em>
Answer: x > -1

0.30 is 30/100, or 30 hundreths. If you simplify 30/100, you get 3/10, which is the same as 0.3, or 3 tenths
Answer:
On Friday he jogged
miles.
Step-by-step explanation:
Given : Eric jogged 3 1/4 miles on Monday, 5 5/8 on Tuesday, and 8 miles on Wednesday. suppose he continues the pattern for the remainder of the week.
To find : How far will Eric jog on Friday?
Solution :
On Monday he jogged ![3\frac{1}{4}=\frac{13}{4}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B13%7D%7B4%7D)
On Tuesday he jogged ![5\frac{5}{8}=\frac{45}{8}](https://tex.z-dn.net/?f=5%5Cfrac%7B5%7D%7B8%7D%3D%5Cfrac%7B45%7D%7B8%7D)
On Wednesday he jogged 8 miles.
He jogged from Monday and Tuesday
![\frac{45}{8}-\frac{13}{4}=\frac{45-26}{8}=\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B8%7D-%5Cfrac%7B13%7D%7B4%7D%3D%5Cfrac%7B45-26%7D%7B8%7D%3D%5Cfrac%7B19%7D%7B8%7D)
He jogged from Tuesday and Wednesday
![8-\frac{45}{8}=\frac{64-45}{8}=\frac{19}{8}](https://tex.z-dn.net/?f=8-%5Cfrac%7B45%7D%7B8%7D%3D%5Cfrac%7B64-45%7D%7B8%7D%3D%5Cfrac%7B19%7D%7B8%7D)
He jogs per day is ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
Now, In Thursday he jogged
![8+\frac{19}{8}=\frac{64+19}{8}=\frac{83}{8}](https://tex.z-dn.net/?f=8%2B%5Cfrac%7B19%7D%7B8%7D%3D%5Cfrac%7B64%2B19%7D%7B8%7D%3D%5Cfrac%7B83%7D%7B8%7D)
In Friday he jogged
![\frac{83}{8}+\frac{19}{8}=\frac{83+19}{8}=\frac{102}{8}=\frac{51}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B83%7D%7B8%7D%2B%5Cfrac%7B19%7D%7B8%7D%3D%5Cfrac%7B83%2B19%7D%7B8%7D%3D%5Cfrac%7B102%7D%7B8%7D%3D%5Cfrac%7B51%7D%7B4%7D)
Therefore, On Friday he jogged
miles.
