Step-by-step explanation:
She drove 45 miles less the first day so simply subtract 45 from the amount of miles she drove on day two (355).
X=(355-45)
Answer:
In 4 months
Step-by-step explanation:
If you keep subtracting 140nfrom 3440 u will get 2880 after you do that 4 times. If you keep adding 220 to 2000 you will get 2880 after you do it 4 times.
Answer:
Step-by-step explanation:
<u>Let's factor the trinomial:</u>
- x² + 14x + 40 =
- x² + 4x + 10x + 40 =
- x(x + 4) + 10(x + 4) =
- (x + 4)(x + 10)
x + 4 is between the answer options
Correct option is D.
Answer: The number is 27
The system of equations is: 7x - 2y = 0
-9x + 9y = 45
<u>Step-by-step explanation:</u>
Let x represent the number in the tens place and y represent the number in the ones place. <u>x</u> <u>y</u>
Then 10x + y = 3(x + y)
When the digits are reversed: 10y + x = 10x + y + 45
Simplify each of the above equations and then create a system of equations:
10x + y = 3x + 3y → 7x - 2y = 0
10y + x = 10x + y + 45 → -9x + 9y = 45
9( 7x - 2y = 0) → 63x - 18y = 0
2(-9x + 9y = 45) → <u> -18x + 18y </u>=<u> 90</u>
45x = 90
x = 2
Input x = 2 into either equation to solve for y:
7x - 2y = 0
7(2) - 2y = 0
14 = 2y
7 = y
