Working with fractions can be tricky, so I like to start by multiplying everything by the LCM of the denominators of the fractions.
In this case, both fractions have a denominator of 4, which means that the LCM is 4 and we will be multiplying everything by 4.
1/4x - 1 = 3/4x - 5
---The below equation looks much more familiar and appears easier to solve.
1x - 4 = 3x - 20
-4 = 2x - 20
16 = 2x
x = 8
Answer: C, x = 8
Hope this helps!

What is the area of the trapezoid?
A trapezoid resting on a base. The top side is labeled 14 in. The bottom side is labeled 30 in. The left side is labeled 15 in. The right side is labeled 20 in. Where the left side and the bottom side meet there is a right angle box.
Answers
Answer:
29.5 inches squared
Step-by-step explanation:
The formula for the area of a trapezoid is [tex]\frac{base1 + base2 * height}{2}[/tex],
so base1 = 14 inches and base2 = 30 inches
since there is a right angle, you know that the height must equal the length of the left side, so the height = 15 inches
then, 14+30+15=59 and 59/2=29.5
therefore, your answer would be 29.5 inches squared

36(3.14)113.04cm²(Exact)You are going to draw 4 cards from a standard deck of 52 cards. How many different combinations of cards could you draw?
Answers
Answer:
Step-by-step explanation:
To start with we can consider how many possibilities there are for the first card which is obviously 52, as any one of the cards in the deck can be found on the top of the pile. The next card is a bit trickier as there are only 51 possible cards that it could be as the first card takes up a spot. The third card now only has 50 possible cards it could and this continues all the way down to the last card.
is that good
Explanation: To find the combinations you can multiply 52 and 4 and you should get 208

Answer:
12,000, 900, 210, 18 4376x3=13128
Step-by-step explanation:
In the 1st box, you put the product of 4,000 x 3 = 12,000
In the 2nd, you put the product of 300 x 3 = 900
In the 3rd, you put the product of 70 x 3 = 210
In the 4th, you put the product of 6 x 3 = 18
Then you add your answers
12,000 + 900 + 210 + 18 = 13,128
The required partial product of 4376 × 3 is 13128.
What is the partial product?In mathematics, partial products are defined as multiplying each digit of one integer by each digit of another number while keeping each digit's place value.
Here,
4376 × 3 = [4000 + 300 + 70 + 6] × 3
Simplifying using the distribution of 3,
= 4000 × 3 + 300 × 3 + 70 × 3 + 6 × 3
= 12000 + 900 + 210 + 18
= 13128
Thus, the required partial product of 4376 × 3 is 13128.

Answers
Answer:
5.66 length (3s.f.)
Step-by-step explanation:
[tex] \sqrt{4 {}^{2} + 4 {}^{2} } [/tex]
= 5.65685
= 5.66 (3 s.f.)
By using the Pythagorean theorem, we will see that the length of DF is 5.7 units.
How to get the length of DF?
We can make a right triangle with the sides: DE, FE, and DF.
Such that we know that:
DE = FE = 4
These two are the cathetus of the right triangle.
Then DF is the hypotenuse.
Now, remember the Pythagorean theorem, it says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, then we have:
(DE)^2 + (FE)^2 = (DF)^2
4^2 + 4^2 =(DF)^2
√32 = DF = 5.7
The length of DF is 5.7 units.

An average adult giraffe is 18 feet tall. A newborn giraffe is about 6 feet tall/ Kayla is building a model of a mother giraffe and her newborn. She wants the model to be no more than 17 inches high.
Answers
Answer:
Mother = 17 inches and then Newborn = 5 (2/3) or 5.66666666667 inches
Step-by-step explanation:
I was sort of guessing based on your question what you were looking for. How I solved this is we know that since the average adult giraffe is 18 feet tall and the average newborn giraffe is 6 feet tall, then the adult giraffe is about 3 times as tall as the average newborn giraffe so the ratio is 3:1 adult: newborn. So with the mother at 17 inches, then since the newborn giraffe is, on average, 3 times smaller than the mother, it is therefore 17/3 = 5.666667 or 5 and 2/3s.

Find the difference. On February 6, 1995, in Sioux Falls, South Dakota, the temperature dropped from 48°F to –16°F in a period of 8 hours. What was the average change in temperature per hour? please help
Answers
Answer:
The average change in temperature per hour was -8°F.
Step-by-step explanation:
Using the equation 48-(-16) we know that the temperature dropped by 64°F.
[tex]48-(-16)=64[/tex]
We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.
[tex]\frac{-64}{8} = -8[/tex]
Therefore, the average change in temperature per hour was -8°F.
