Recipe 1 & 3
Recipe 2 & 3
Recipe 1 & 2
All recipes taste the same.
Answer:
Recipes 1 and 2
Step-by-step explanation:
To find the answer, we need to simplify the ratios:
4:6 = 2:3
6:9 = 2:3
9:12 = 3:4
We can now clearly see that Recipes 1 and 2 will taste the same, since they have the same OJ to PJ ratio.
Answer:
The answer is Recipe 2&3 because both of the factors for 2&3 can be divided by 3 Recipe 1 can‘t.
Step-by-step explanation:
Does that make sense?
Help pretty please ^^ 100 points will be giving a brainlist if i get it right!
The ratio of balls to tennis balls is 4:7 is a correct statement; however, we need to check the other questions for reliablity.
For every 6 basketballs, there are 10 dodge balls is a wrong statement because the number of basketballs is 12 and the number of dodge balls is 18 not 20. So, this answer is wrong.
None of the above is wrong because the first answer is correct so we can cross out c.
Now we know that A is the correct answer!
It is A, the ratio of soccer balls to tennis balls is 4:7.
Soccer Balls : 8
Tennis balls: 14
8 divided by 2 is 4 and 14 divided by 2 is 7.
4:7
B is not right because
Basketball: 12
Dodgeball: 18
"For every 6 basketballs, there are 10 dodge balls."
12 divided by 2 is 6
If it was 10 dodge balls for every 6, dodge balls would be 20 because there are 2 6s in a 12.
And it can't be C, none of the above because A is correct.
So yea it's A.

The sale price of an item is $160 after a 20% discount. What was the original price of the item?
Answer:
200 sorry read that wrong
Step-by-step explanation:
Answer:
The original price of the item is $200.
Step-by-step explanation:
Let the original price be 'x'.
The sale price of an item is $160 after a 20% discount.
i.e. original price - 20% of original price = $160
x-20/100x=160
x-0.2x=160
0.8x=160
x=160/0.8
x=200
Therefore, the original price of the item is $200.

5 ( f + 4) = 4 ( f - 6)
f = -44
Hope this helps :)
Answer:
The answer is -44
Step-by-step explanation:
First, you use distributive property on each side.
5xf + 5x4 = 4xf-4x6
5f+20=4f-24
Then you subttract 5f to both sides of the equation.
5f+20=4f-24
-5f -5f
20=-1f-24
Next, you add 24 to both sides of the equation.
20=-1f-24
+24 +24
44=-1f
Finally, you divide -1f from each side of the equation.
44=-1f
/-1f /-1f
Your final answer should be -44=f
or f = -44

Answer:
24.554
Step-by-step explanation:
Answer:
24.554
Step-by-step explanation:
interoperate your solution in the context of the problem.
f(10)=1.75r+9
Answer:
Simplifying
f(r) = 5 + 1.75r
Multiply f * r
fr = 5 + 1.75r
Solving
fr = 5 + 1.75r
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'r'.
f = 5r-1 + 1.75
Simplifying
f = 5r-1 + 1.75
Reorder the terms:
f = 1.75 + 5r-1
Step-by-step explanation:
tada i think
Let's solve for f.
f(10)=1.75r+9
Step 1: Divide both sides by 10
10f/10 =1.75r+9/10
Answer : f=0.175r+9/10

Sam invested $14,000 in a stock that was expected to show an 18% increase in value. If all goes as expected, what will Mr. Bronson’s stock be worth after one year?
a
$11,480
b
$2,520
c
$16,520
d
$252,000
25p
Answer:
C
Step-by-step explanation:
we can convert 18 percent to .18 and then we can multiply 1.18 by 14000 to get our answer. if you don't do the extra 1 before the decimal you will get the 18 percent then have to add it to 14000 so adding the 1 before doesn't affect anything, it just makes it easier, without it it would be a two step problem (adding the .18 to 14,000).
Answer:
C is the right answer

whats the answer to y/6+6=-19
Answer:
y = -150
Step-by-step explanation:
y/6+6=-19
Subtract 6 from each side
y/6+6-6=-19-6
y/6 = -25
Multiply each side by 6
y/6 * 6 = -25*6
y = -150

Julie is out shopping and finds a $96.00 basketball that was marked down by 25%.
How much was the item originally?
Answer: The original price of the basketball was $128.
Step-by-step explanation: The new price is 25% less than the original. That is the same as 25% from 100% is 75%.
So we can use that to calculate the original price:
96 = .75x . divide both sides by .75
96/.75 = x
128 = x That is the original price.
Check: $128 × .25 = $32, the amount of the discount.
$128 - 32 = $96 That is the price Julie paid.
Two sides of a triangle have lengths of 7 and 15. Which inequality represents the possible lengths for the third side?
A) 8 < x < 7
B) 7 < x <15
C) 8 < x < 15
D) 8 < x <22
Answer:
D
Step-by-step explanation:
From the triangle inequality, we know that the two small sides must be greater than the largest side. Let's let x be the third side:
[tex]7+15>x[/tex]
However, 15 can also be our largest side. So:
[tex]7+x>15[/tex]
Let's solve for x for both inequalities.
First inequality:
[tex]7+15>x[/tex]
Add:
[tex]22>x[/tex]
Flip:
[tex]x<22[/tex]
Second inequality:
[tex]7+x>15[/tex]
Subtract 7 from both sides:
[tex]x>8[/tex]
So, we have the compound inequality:
[tex]x>8\text{ and } x<22[/tex]
Combine:
[tex]8<x<22[/tex]
Our answer is D
And we're done!
