Hayden had 2 1/2 gallons of water in his watering can. The seed packet said to use 1/4 of a gallon for peppers and 5/8 of a gallon for tomatoes. Hayden then used some of the water for lettuce. If Hayden had 3/4 gallons of water left over, about how much water did he use for lettuce?
Answers
Answer:
7/8
Step-by-step explanation:
1/4 + 5/8 = 2/8 + 5/8 = 7/8
= amount used for pepper and tomatoes
2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4
= total amount used
so
7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

6x-14(17+19x)=-11x+13
Answers
Step by Step:
1) 6x-238-266x=11x+13 (multiply 14 with 17 and 19x)
2) -260x-238=11x+13 (like terms put together)
3) -260x-238-11x=13 (combine the x’s)
4) -260x-11x=13+238
5) -271x=13+238
6) -271x=251
7) divide both sides by -271

A box of cereal states that there are 90 calories in 3/4 cup serving. How many calories are there in 4 cups of the cereal
Answers
Answer:
480
Step-by-step explanation:
Let x be the calories in 4 cups
Set it up
[tex]\frac{90}{\frac{3}{4}}=\frac{x}{4}[/tex]
Step 1: Switch sides
[tex]\frac{x}{4}=\frac{90}{\frac{3}{4}}[/tex]
Step 2: Apply fraction rule
[tex]\frac{x}{4}=\frac{90\cdot \:4}{3}[/tex]
Multiply
[tex]\frac{x}{4}=\frac{360}{3}[/tex]
Divide
[tex]\frac{x}{4}=120[/tex]
Step 3: Multiply both sides by 4
[tex]\frac{4x}{4}=120\cdot \:4\\\\=480[/tex]
There are 480 calories in 4 cups of the cereal.

Ethans solution and reasoning for solving an equation are shown below:
Given: 4/2x - 10 = 30
Which reason is incorrect?
(9th grade math Algebra 1)
Answers
Answer:
Reason 4 is wrong in Ethan's solution.
Step-by-step explanation:
Reason 4 is incorrect because at this step in the answer we already have one variable which is unknown on the left side and then one constant which can be seen on the right. So, instead of multiplying the fractions the way Ethan is doing, all you need to do now is just simplify the expression instead of complicating the step.

B. A statement that is accepted as true without proof
C. a statement explaining the meaning of a geometric term

Answers
Answer:
Step-by-step explanation:
It's D.
A theorem is true by some sort of mathematical logic.
It is not a definition. Not C
It is not in the end true because of inductive reasoning (a theorem may lend itself to inductive reasoning, but it must be proved.) Not A
It certainly not assumed to be true without proof. Not B

From step 2 to step 3 they added 6x to both sides,canceling out the -6x on the left side and adding 6x with the 5x
From step 3 to step 4 they subtracted 2 from both sides, canceling it out on the right side and subtracting 2 from 8 to get 6
From step 4 to step 5 they try and get x alone by dividing both sides by 11, canceling out the 11 on the right side and leaving a fraction the left

Step-by-step explanation:
This question is about complex numbers.
so,
in this type of questions we have to multiply this fraction by the conjugate of the denominator
conjugate of the denominator is 3-2i
1) 5i(3-2i)/(3+2i)(3-2i)
2) 15i-10i^2/9-4i^2 ( we know that i^2 = -1 )
3) 15i+10/9+4
4) 15i+10 / 13
The perimeter of Stephanie’s triangle is half the perimeter of Juan’s triangle. Juan’s triangle is shown. Write a numerical expression to describe the perimeter of Stephanie’s triangle.
Answers
The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]
Let the sides of Juan's triangle be x, y and z. So:
[tex]x = 5 \\ y = 8\\ z = 12[/tex]
The perimeter (J) of Juan's triangle is calculated by adding all sides.
So:
[tex]J =x +y +z[/tex]
This gives:
[tex]J =5 + 8 + 12[/tex]
[tex]J =25[/tex]
From the question, we understand that:
The perimeter (S) of Stephanie's triangle is half that of Juan.
This means that:
[tex]S = \frac 12J[/tex]
Substitute 25 for J
[tex]S = \frac 12 \times 25[/tex]
Hence, the numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]
