Answer:
Boat = 20 mph
Current = 5 mph
Step-by-step explanation:
If b is the speed of the boat, and c is the speed of the current, then:
b + c = 225 / 9 = 25
b − c = 225 / 15 = 15
Solve the system of equations with elimination.
2b = 40
b = 20
Plug back into either equation to find the speed of the current.
c = 5
Answer:
Jamie has 44 pairs of shoes
Step-by-step explanation:
Let
Jamie= x pairs of shoes
Suzie= 33 less than twice the amount of shoes Jamie has
2x - 33 = 55
Solve:
2x - 33 = 55
Collect like terms
2x = 55 + 33
2x = 88
Divide both sides by 2
2x / 2 = 88 / 2
x = 44
Jamie = x = 44 pairs of shoes
Therefore, Jamie has 44 pairs of shoes
The product (multiply) of a number (x) and four (4) is at most (≤) -10.
4x ≤ -10
To solve this, divide both sides by 4
x ≤ -2
Answer:
She would be paying $2,622 total.
Step-by-step explanation:
1. To get how much she'd be paying for 24 months, all you have to do is multiply 24 times 95.
2. To get the down payment you had to ask yourself what's 15% of 2,280. 15% of 2280 is 342.
3. Add those together and you'd get the total payment.
Simple.
Oh and gimme Brainliest if it's correct.
<span>this is how i did it
10(9)(d)= 210
90d= 210
d=2.3 feet.</span>
