Answer:
D. 4/7 = 24/28
Step-by-step explanation:
In any proportion, the value of the numerator and denominator does not change if is multiplied by the same value.
We know that 4*6 = 24, so the numerator holds true. However, 7*6 is 42. In the same vein, 7*4 is 28, so the denominator would hold true. However, 4*4 is 16. Thus, the proportion has not been multiplied by the same value.
In order to get 24/28 from 4/7, you would have to multiply by 6/4, which is not the same value.
Answer:
<u>Answer (a):</u>
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
<u>Answer (b)</u>
9 large dogs.
Step-by-step explanation:
Paws at Play made a total of $1234 grooming 22 dogs.
Paws at Play charges $43 to groom each small dog and;
$75 for each large dog.
Let the number of small dogs be 's'
And the number of large dogs be 'l'
<u>A system of equations will be:</u>
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
Solving this set of simultaneous equations by elimination, we simply multiply (i) by 43 to get;
43s + 43l = 946 ... (i)
43s + 75l = 1234 ... (ii)
Subtracting (i) from (ii) we get;
32l = 288 , l = 
= 9
So there are 9 large dogs.
I don’t know it’s could be better if I didn’t have any money for that you could do it omg is it like that a lot but you don’t want it anyway I can do
Answer:
9.4 units
Step-by-step explanation:
Step one:
given data'
We are given the coordinates
x1=4.2
x2=-5.2
y1=-2
y2=-2
Required
The distance between the points
Step two:
The expression for the distance is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((-5.2-4.2)²+(-2+2)²)
d=√((-9.4)²
d= √88.36
d= 9.4 units
