Answer:
50 seconds
Step-by-step explanation:
We are told in the question that the distance between them = 100ft
Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second.
The formula for Distance = Speed × Time.
Hence, the Algebraic equation is given as:
6ft/s × t = 4ft/s × t + 100
6t = 4t + 100
6t - 4t = 100
2t = 100
t = 100/2
t = 50 seconds
It will take 50 seconds for the boys to meet.
what ratios are equivalent to 12:3
Step-by-step explanation
Ratio equivalent to 12:3
= 12:3
= 12/3 (.°.3x4= 12 and 3x1=3)
= 3x4/3x1 (.°. cancellation of 3 from numerator and denominator)
= 4/1
likewise, 4:1 , 60:15 , 84:21 , 132:33..............etc no. of ratios are equivalent to 12:3
.°. Required ratios which are equivalent to 12:3 are4:1 , 60:15 , 84:21 , 132:33..............etc
The ratios are equivalent to the given ratio are 4:1 and 24:6.
The given ratio is 12:3.
When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another.
Here, the equivalent ratio to 12:3 are
12/3 : 3/3
= 4:1
12×2:3×2
= 24:6
Therefore, the ratios are equivalent to the given ratio are 4:1 and 24:6.

Enrique took his brother out
to dinner to celebrate. He
decided to leave a 25% tip
because the service was
excellent. The tip was
$18.10. How much was the
original bill?
Answer:
72.4$
Step-by-step explanation:
We can use cross multiplication here
[tex]\frac{18.10}{originalbill} = \frac{25}{100}[/tex]
18.10 x 100 = 25 x original bill
1810 = 25 x original bill
72.4 = original bill
Jolene has 30 days to prepare for a
bicycle race. She will bicycle 15 miles
each day. How many miles will
Jolene have bicycled during her
training?
Answer:
450 miles in total during her training
Step-by-step explanation:
Since it does say she has 30 days to train and she said she will ride her bike 15 miles everyday she trains so she will have ridden her bike for 450 miles in total
30 days to train x 15 miles per day = 450 miles in total
Could x = -5 be a solution to the inequality -6 < 3x + 9 < 21?
Answer:
x=−5<x<4Step-by-step explanation:
So you think that x = -5 is the solution for the inequality? Let's check it out.
(Check)
- Substitute x = -5 in the inequality
[tex]-6<3(-5)+9<21\\-6<-15+9<21\\-6<-6<21[/tex]
If it was the symbol ≤ you'd be correct, but it's < so It's a bit wrong.
Now let's solve the inequality. Separate the inequality by parts.
[tex]\left \{ {{-6<3x+9} \atop {3x+9<21}} \right. \\\left \{ {{-6-9<3x} \atop {3x<21-9}} \right. \\\left \{ {{-15<3x} \atop {3x<12}} \right. \\\left \{ {{x>-5} \atop {x<4}} \right.[/tex]
Therefore, the inequality is true only when x > -5 or x < 4.
(Check)
- Substitute x = -4 in the inequality.
[tex]-6<3(-4)+9<21\\-6<-12+9<21\\-6<-3<21[/tex]
The inequality is true for first case.
- Substitute x = 3 in the inequality
[tex]-6<3(3)+9<21\\-6<9+9<21\\-6<18<21[/tex]
The inequality is true for second case.
So the answer for inequality is -5 < x < 4
That means only {-4, -3, -2, ..., 3} can make the inequality true.

Answer:
x = 16
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
10*x-5*x-3*x-(12)=0
1.1 Pull out like factors :
2x - 12 = 2 • (x - 6)
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
2.2 Solve : x-6 = 0
Add 6 to both sides of the equation :
x = 6

What is the distance between (4, 7) and (2,2)?
let's see what to do buddy...
To find the distance between two points, we have the following relation, which is derived from the Pythagorean relation, and we do not need to prove it :
a = ( 2 , 2 ) and b = ( 4 , 7 )
[tex]d = \sqrt{ ( \: {y(b) - y(a)} \: )^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]
Now just put the coordinates in the equation :
[tex]d = \sqrt{ ({7 - 2})^{2} + ({4 - 2})^{2} } \\ \: \: \: d = \sqrt{ {5}^{2} + {2}^{2} } \\ d = \sqrt{25 + 4} \\ d = \sqrt{29} [/tex]
So the distance between them equal :
[tex] \sqrt{29} [/tex]
And we're done buddy.
Thanks for watching good luck ♥️♥️♥️♥️♥️.
