Let the angles are x, y and z.
Let the smallest angle is x
one angle is 78 degrees more than the smallest angle.⇒ y = x + 78 → (1)
the third angle is 4 times as large as the smallest angle. ⇒ z = 4 x → (2)
we should know that the sum of the angles of the triangle = 180°
∴ x + y + z = 180 →(3)
substitute from (1) and (2) at (3)
∴ x + ( x +78) + (4x) = 180
∴ 6x = 180 - 78 = 102
∴ x = 102 ÷ 6 = 17°
∴ y = 17 + 78 = 95°
∴ z = 4x = 68°
So, the measures of all three angles are 17°, 95° and 68°

Solve −4(x + 10) − 6 = −3(x − 2). (1 point)
Hey there!!
Given equation :
... -4 ( x + 10 ) - 6 = -3 ( x - 2 )
Using the distributive property :
... -4x - 40 - 6 = -3x + 6
Combining like terms :
... -4x - 46 = -3x + 6
Adding 46 on both sides :
... -4x = -3x + 52
Adding 3x on both sides :
... -x = 52
... x = -52
Hope helps!

Isolate the y. Treat the less than or equal like an equal sign.
Do the opposite of PEMDAS. First, add 1 to both sides
3y - 1 (+1) < 3 (+1)
3y < 4
Next, divide 3 from both sides
3y/3 < 4/3
y < 4/3
y < 4/3 is your answer

what is 0.012 as a fraction
To convert 0.012 to a fraction, you multiply by 1000 to get 12/1000 and then simplify it to 3/250. Therefore, 0.012 as a fraction is 3/250.
To convert the decimal 0.012 into a fraction, follow these simple steps:
Write down 0.012 as 0.012/1.
Multiply both the numerator and the denominator by 1000 to get rid of the decimal point:
0.012 x 1000 / 1 x 1000 = 12 / 1000.
Simplify the fraction by finding the greatest common divisor (GCD) of 12 and 1000, which is 4:
(12 ÷ 4) / (1000 ÷ 4) = 3 / 250.
Thus, 0.012 as a fraction is 3/250.

Step-by-step explanation:
Aaron needs 24 inches of copper wire for an experiment. The wire is sold by the centimeter. Given that 1 inch = 2.54 centimeters, how many centimeters of wire does Aaron need? Hint: 1/2.54 = 24/x , remember you have to keep inches on top and centimeters on bottom of both fractions so they are equal. What is the answer to this problem? PLS HURRY
[tex]\frac{1}{2.54} =\frac{24}{x}[/tex]
Multiply both sides by 2.54.
[tex]1=\frac{24}{x} (2.54)[/tex]
[tex]= \frac{60.96}{x}[/tex]
Multiply both sides by x.
x = 60.96
Hence, Aaron needs 60.96 centimeters of wire.
Final answer:
Aaron needs 60.96 centimeters of copper wire for his experiment, calculated by multiplying 24 inches by the conversion factor of 2.54 cm/inch.
Explanation:
Aaron needs to convert 24 inches of copper wire to centimeters. Since 1 inch equals 2.54 centimeters, Aaron can calculate the length of wire needed by multiplying the number of inches by the conversion factor. By performing the multiplication 24 inches × 2.54 cm/inch, the result will give the length of wire needed in centimeters.
To find the answer, complete the multiplication:
24 inches × 2.54 cm/inch = 60.96 centimeters.
Therefore, Aaron needs 60.96 centimeters of copper wire for his experiment.

Step-by-step explanation:
Mark and his friends Byron were watching a superhero movies. During the movie mark ate 5 pieces of candy . Byron ate 7 times as much candy as mark. How much candy did Byron eat.?
Final answer:
To find out how much candy Byron ate, we multiply the number of candies Mark ate, which is 5, by 7. Byron ate a total of 35 pieces of candy.
Explanation:
The question involves solving a basic multiplication problem to determine how much candy Byron ate if Mark ate 5 pieces of candy and Byron ate 7 times as much. According to the given scenario, we can represent this mathematically as:
Mark ate 5 pieces of candy. Byron ate 7 times as much candy as Mark did. To find out the total pieces of candy Byron ate, we multiply the number of candies Mark ate by 7. Therefore, Byron ate 5 pieces × 7 = 35 pieces of candy.
This arithmetic calculation shows us Byron's total candy consumption during the movie.

Find the equation of the line that is perpendicular to the line y=-1/3x-1 and passes through the point (1,5)
To find the equation of the line perpendicular to y = -1/3x - 1 and passing through the point (1,5), we use the negative reciprocal of the original slope (which is 3) and the point-slope form to finally arrive at the equation y = 3x + 2.
The student is asking for the equation of a line that is perpendicular to a given line and passes through a specific point. The given line has the equation
y = -1/3x - 1. Because perpendicular lines have slopes that are negative reciprocals of each other, the slope of the line we're looking for is 3. Using the point-slope form of the equation of a line, we plug in the slope and the coordinates of the point (1,5) to get
y - 5 = 3(x - 1).
Simplifying this equation gives us the standard form of the line:
y = 3x + 2.

You work 20 hours a week at a store in our $8.50 per hour. At another job you earn $8.00 per hour and can work as many hours as you want. If you want to earn $370 for the week, how many hours will you need to work at the second job?
For the second job you work for $8.00 per hour and you want to make $370 for the week so its just simple division.
$370/$8.00 is 46.25 hours a day which means you will have to work close to 46-47 hours a day to make $370 in a week.

A pizza eating participant can eat 3 slices ok pizza in 2 minutes if he continues at this rate then how many slices of pizza will he eat in 10 minutes
at this rate, he can eat 15 slices of pizza in 10 minutes **wow!!**
we can do this by setting it up as a proportion: 3slices/ 2 minutes= ?/1 minute
we divide 3 by 2 to get how many slices he can eat in one minute, which is 1.5
so, now, we just have to multiply 1.5 times 10 minutes, and we get 15 slices of pizza per 10 minutes

The diameter of the moon is about 3,476 kilometers the distance from earth to the moon is about 384,400 kilometers about how many moons could be lined up in a row between earth and the moon round the nearest whole number
384,400 /3476 = 110.587 so 111
because .587 is more than half way from 110 to 111
Remark
You have to make up your own formula here. You also should estimate the answser. That's always good practice. It makes you think about Math.
Estimate
If you take 384,000 and estimate it to be 300000 and do the same with the diameter to make it 3000
300,000 / 3000 = 100 about. You should get an answer of 100
Formula
Distance to the moon (D)= number of moons (n) * diameter of 1 moon (di).
Givens
D = 384000
n = ??
di = 3476
Solution
384000 = n * 3476 Divide by 3476
384000 /3476 = n / 3476
n = 110.5 moons which I think you should like round to 110.
You could fit 110 moons in the given distance
