Answer:x>2
Step-by-step explanation:
4x/4>8/4
Answer:
- commutative property
- distributive property
Step-by-step explanation:
The expression
4.7x + 10.4 + 15.3x − 8.4x + 15.6
can be simplified in a few stages. First of all, we use the commutative property of addition to swap terms 2 and 3.
4.7x +15.3x +10.4 -8.4x +15.6
Next, we use the distributive property to factor x from the first two terms.
(4.7 +15.3)x +10.4 -8.4x +15.6
Now we perform addition.
20x +10.4 -8.4x +15.6 . . . . . . . . equivalent expression
Answer:
D
Step-by-step explanation:
We can substitute y = 2x + 1 in the second equation
2x + 1 = -7x + 8
Add 7x to both sides
9x + 1 = 8
Subtact 1 from both sides
9x = 7
x = 7/9
Substituing x in the first equation
y = 14/9 + 1
x rounds to 0.8
y rounds to 2.5
Answer: Rate > 12 miles/day
x > 12
She must run more than 12 miles each day
Mona wants to run more than 60 miles this week. She ran a total of 24 miles during the first 4 days of the week. Which number line represents the number of miles Mona must run each day if she wants to meet her goal?
answer choices
x ≥ 10
x = 12
x > 10
x > 12
Step-by-step explanation:
To complete more than 60 miles a week.
After running 24 miles during the first 4 days
We are left with (7-4) days = 3 days
And also,
(60-24) miles to complete the weekly target
> 36 miles (more than 36miles)
Therefore, the number of miles needed to cover per day in the next 3 days is given as.
Rate > distance/time
Rate > 36miles/3days
Rate > 12 miles/day
