Porch = (30 x 15) - [(30 + 20)5/2]
Porch = 450 - 125
Porch = 325
House = (30 x 10) + 2(125)
House = 300 + 250 = 550

POV from the angle measure
Angle = 64°
Opposite = 13
Adjacent = x
Step 3: Solve for x
Substitute: tan64° = 13/xMultiply x on both sides: xtan64° = 13Isolate x: x = 13/tan64°Evaluate: x = 6.34052

5x – 7 = 19
Give your answer as an

Answers
5x - 7 = 19
Add 7 to both sides:
5x = 26
Divide both sides by 5:
x = 26/5
[tex]5x - 7 = 19[/tex]
Move -7 to another side and become + 7. Whenever we move to another side, we change the sign/operator to opposite. Ergo, changing from plus to minus and multiply to divide.
[tex]5x = 19 + 7 \\ 5x = 26[/tex]
We are at this part. Now to move 5 which is multiplying the x. So we move 5 from multiply to divide 26.
[tex]x = \frac{26}{5} [/tex]
Ergo, the answer is x = 26/5

Answer:
marked price = Rs. 3900
Step-by-step explanation:
The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.
The marked price is Rs. 3900.
_____
Check
A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
Answers
Answer:
350 girls
Step-by-step explanation:
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.

So the question is asking when it will be the same amount of water, which means we are dealing with an EQUAL sign because they want to know when it’s the SAME. So, we look at the equation again and it’s saying that the 4.5 gallon tub is gaining water, and the 7 gallon tub is losing water. Because C also has an equal sign, it isn’t the right choice because of the fact that the 7 gallon tub in that equation has a + sign instead of a - sign like B does.

Answer:
x = no solutions

Step-by-step explanation:
Step 1: Define equation
4x - 5 = x - 1 + 3x
Step 2: Solve for x
Combine like terms: 4x - 5 = 4x - 1Subtract 4x on both sides: -5 ≠ -1Here we see that -5 does not equal -1.
∴ This equation has no solutions.

A function relating these variables is N(x) =N(x)=

So N(14) =N(14)=
, meaning 1414
.
Answers
Answer:
Independent Variable: Number of bagels bought
Dependent Variable: Total cost because it depends on the number of bagels bought.
Function: N(x)=1.75x
So, if x is the number of bagels bought, N(14) means that 14 bagels were bought. So you multiply 14 by the price; 1.75. So, N(x)=1.75*14 = $24.5
Step-by-step explanation:
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is V(x) =1.75x.
So V(14) = 24.5, meaning 14 bagels will cost 24.5 dollars.

A recipe requires 1 2/3 cups of sugar. If Mrs.Marina is going to make one and one half of the recipe, then how much sugar does she need
Answers
5/3 + 5/6
10/6 + 5/6
she needs 15/6 or 2 3/6 or 2 1/2 cups of sugar
Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
Here it is given that :
A recipe requires 1 (2/3) cups of sugar.
That is 1 recipe requires = 1(2/3) cups of sugars
= 5/3 cups of sugar
Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :
1 recipe requires = 5/3 cups of sugar
1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar
3/2 recipe requires = (5/3) x (3/2) cups of sugar
3/2 recipe requires = 5/2 cups of sugar or 2.5 cups of sugar.
Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.
