Hello I'm Chloe Can you Help me, Thank you :)
y varies proportionally with x. When x = 2, y = 18.
What is the constant of proportionality for this relationship?
Answer:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?
1
A) 40
B) 13
C) 26
D) 12
Answer:
B. 13
Step-by-step explanation:
We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.
"The sum of two numbers is 46 and their difference is 20."
Meaning we have two equations :
X + Y = 46
X - Y = 20
Looking at the last part of "their difference is 20." We can assume X = Y + 20
So substitute the assumed equation into X + Y = 46
(Y + 20) + Y = 46
2y + 20 = 46
Subtract 20 from both sides :
2y = 26
Divide 2 by both sides :
y = 13
There you go.

The difference in the price of 2 backpacks is $19.30. If one backpack costs $39.00, which of the answer choices could represent the price of the other backpack?
Answer:
$19.70 OR $58.30
Step-by-step explanation:
I say either or because I can't see the answer choices.
Its either adding or subtracting from the one backpack we know is $39.00
If we know the difference between the two is 19.30
39.00+19.30 = 58.30
39.00-19.30= 19.70
See if either of those are available :) Hope this helps! :)

e is 5 more than d
f is 7 less than d
work out e-f
Answer:
12
Step-by-step explanation:
(5+d)-(d-7)
5--7 = 5+7 = 12
To prove this:
d = 10
e = 5+10 =15
f = 10-7 = 3
15 - 3 =12

(I’ll give brainliest) Jack designed a bridge that would be 0.2 miles long and 3/5 of the bridge has been built. How long is the section of the bridge that is finished? Show how you know.
Answer: 0.12
Step-by-step explanation: Well since 5/5=1 and in this case 3/5 of 0.2 or
3/5 x 0.2 = 0.12miles of the bridge is finished. to check do 0.2*2/5 since 2/5+3/5=5/5 or the total 0.2miles. so 0.2*2/5 =0.8 and 0.8+0.12= 0.2

workout 4 1/7 + 1 1/2
Answer:
Take 2 1/7 - first multiply the denominator by the whole number to give 14 and now add the numerator to this number to get 15 - the fraction in improper form is 15/7. Do the same process with 1 1/4 - so 4 x 1 = 4 and now 4 + 1 = 5 - the new fraction is 5/4.
