1) Assuming that 1 month is 30 days. We would take 30 (# of days in the month) divided by 4, which would be 7.5. So every 7.5 days ( or 1/4 of a month) she will build 1 1/2 simple machines. so 1 1/2 times 4 equals 6. She will build 6 simple machines each month.
3) D. 6 miles, you would take 60 divided by 6 which is 10, divided by 3/5 which is 6.
Solve for x:
1.
4x - 7 = 3
Add 7 to both sides
4x = 10
Divide both sides by 4
x = 10/4
Simplify:
x = 5/2
Answer for question 1: x = 5/2
2.
13 + 2x/3 = 15
Multiply both sides by 3
39 + 2x = 45
Subtract 39 from both sides
2x = 6
Divide both sides by 2
x = 3
Answer for question 2: x = 3
3.
10x + 7 = 15
Subtract 7 from both sides
10x = 8
Divide both sides by 10
x = 8/10
Simplify
x = 4/5
Answer for question 3: x = 4/5
Answer:
-2 ⩽ x
Step-by-step explanation:
x(x + 3) ⩽ x (2x + 5) divide both sides of tge inequality with x
x + 3 ⩽ 2x + 5 subtract x from both sides
3 ⩽ x + 5
-2 ⩽ x
The answer is 10:40
so 1:4
add it up
1+4=5
so 5 total units
$50=5 units
divide by 5
$10=1 unit
so 1:4=10:10 times 4=10:40
the answer is 10:40
The reflected points would be (-3,-7)
The x coordinate would stay the same but the y-coordinate would be the opposite
