Answer:
-32 = 3x - 4y
Step-by-step explanation:
Let's first eliminate the fraactional coefficient by multiplying both sides by 4:
4y - 8 = 3x + 24
Next, combine the constants: 4y = 3x + 32
Finally, write this result in the form Ax + By = C:
-32 = 3x - 4y

What is the solution to the system of equations?
Answer:
x=-4 y=-1
Step-by-step explanation:
Let's solve your system by substitution.
−3x−8y=20;y=5x+19
Rewrite equations:
y=5x+19;−3x−8y=20
Step: Solve y=5x+19for y:
y=5x+19
Step: Substitute5x+19foryin−3x−8y=20:
−3x−8y=20
−3x−8(5x+19)=20
−43x−152=20(Simplify both sides of the equation)
−43x−152+152=20+152(Add 152 to both sides)
−43x=172
−43x
−43
=
172
−43
(Divide both sides by -43)
x=−4
Step: Substitute−4forxiny=5x+19:
y=5x+19
y=(5)(−4)+19
y=−1(Simplify both sides of the equation)
Answer:
x=−4 and y=−1
Dillon peeled 40 pounds of potatoes. How many ounces of potatoes did Dillon peel?
Answer:
640
Step-by-step explanation:
40 pounds = 640 ounces
The ounces of potatoes that Dillon peeled is 640 ounces.
What is Unit Conversion?Unit conversion is defined as expressing the same quantity by different measurement units.
For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.
Given that,
Amount of potatoes that Dillon peeled = 40 pounds
We have to convert the same amount of potatoes in to the measurement unit of ounces.
We have to convert the unit.
We have the measurement unit that,
1 pound = 16 ounces
40 pounds = 40 × 16 = 640 ounces
Hence 640 ounces of potatoes did Dillon peel.

3. A bag contains 4 white, 3 blue, and 6 red marbles. A marble is drawn from the bag, replaced,
and another marble is drawn. Find the probability that
both marbles are red.
PLZ HELP ME!!! ASAP PLZ
Answer:
Hope this helps! If I could have brainliest I'm trying to rank up.
Step-by-step explanation:
First find the probability of each color being drawn.
We need to find the total number of marbles first.
4 + 3 + 6 = 13
Everything will be over 13.
Probability of a white marble being drawn --> 4/13
Probability of a blue marble being drawn --> 3/13
Probability of a red marble being drawn --> 6/13
Now to find the probabilities of more than one being drawn, we can multiply.
Part A:
6/13*6/13=36/169
Part B:
3/13*3/13=9/169
Part C:
6/13*6/13=18/169
Part D:
7/13*7/13=49/169

Clare said that 4/3 divided by 5/2 is 10/3 She reasoned: 4/3 x 5 equals 20/3 and 20/3 divided by 2 is 10/3 Explain why Clare's answer and reasoning are incorrect. Find the correct quotient.
Answer: See explanation
Step-by-step explanation:
4/3 ÷ 5/2
To solve this further, the minus sign changes to multiplication and the inverse of 5/2 is written. This will be:
= 4/3 ÷ 5/2
= 4/3 × 2/5
= 8/15
Claire's reasoning is wrong as she didn't multiply by the inverse of the number.
Which measure of center best represents this set of data? Number of television sets in the home: 4, 4, 2, 4, 4, 1, 3, 4, 2, 4 * 1 point Mean Mode IQR Median
Answer:
Mean
Step-by-step explanation:
Given
[tex]Data: 4, 4, 2, 4, 4, 1, 3, 4, 2, 4[/tex]
Required
Best measure of center
The mean is considered the best measure of center when there are no outliers in the given data.
Outlier is when a particular data set is far away from other datasets.
For instance: 20 is an outlier in the following data sets: [tex]4, 4, 2, 20, 4, 4, 1, 3, 4, 2, 4[/tex]
Also, the given data are not open-ended.
An open-ended data is as follows: [tex]1, 2, 3, 4, 5\ or\ more[/tex]
Since we do not have any of the above conditions, then the mean is the best center to use.
A farmer sells 9.4 kilograms of pears and apples at the farmer's market. 2 5 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Answer: 6.9 kg
Step-by-step explanation:
Given
The combined weight of apple and pears is 9.4 kg
If pears weigh 2.5 kg
The weight of apples is the subtraction of pears weight from the total
[tex]\Rightarrow 9.4-2.5=6.9\ kg[/tex]
Thus, the farmer sells 6.9 kg of apples
Use the volume formula to find the volume of a box with the dimensions 29.3cm by 22.7cm by 5.3cm . Round your answer to the nearest hundredth
Answer:
3525.08 cm³
Step-by-step explanation:
Volume of box = length x breadth x height
= 29.3cm x 22.7cm x 5.3cm = 3525.083 cm³
hundredth is the second number after the decimal place. To round off to the nearest hundredth, look at the number after the hundredth, if it is equal or greater than 5, add one to the hundredth value. If it is not, add zero
Edward and Jacob are competing for the same job cutting firewood. While interviewing,
Edward reported that he can cut five cords of firewood in eight hours. (A cord is the
official measurement for firewood. It is actually a measurement for volume.) Jacob,
trying to sound more impressive, says he can cut 162 cords in 100 hours. Who would you
hire as the better firewood cutter? Why? Explain completely.
Answer:
I would hire Jacob.
Step-by-step explanation:
Jacob is trying to sound more impressive knowing that Edward has more cords per hour. The writers of the question wouldn't say "trying to SOUND more impressive" if Jacob actually WAS more impressive. But maybe that's what they want you to think. If you take the 5 cords of Edward and divide it by the eight hours that it takes him to do you will notice he has an average of 0.625 cords per hour. And if you take a look at Jacob's average you immediately notice that he has an average of ABOVE 1. Jacob has an average of 1.62 cords per hour. Therefor Jacob is more efficient in this category of work. That's why I would hire Jacob.

PLEAS HELP ITS FOR A TEST
-3a-4b+5
(3a - 6b +12)- (6a - 2b+ 7).
step 1: remove parentheses and change 2b +7 to 2b -7 and 6a -2b to 6a +2b
3a - 6b +12- 6a + 2b- 7
-3a-4b+5
step 2: from 3a - 6b +12- 6a +2b- 7
subtract: 3a - 6a= -3a.
now its -3a - 6b + 12 - 6a + 2b - 7
then 6b - 2= 4
now is -3a - 4b + 12 - 7
then 12 - 7 =5
Answer: -3a-4b+5
