A triangle has one angle that is three times the size of another, and a third angle that is 16degrees smaller than the larger of the previous two angles. What is the measure of each angle?
Answer:
26, 68 and 84
Step-by-step explanation:
Let the angle that is three times smaller than another be X.
Since the angle sum of a triangle is 180 degrees, we can form the following equation:
X + 3X + (3X- 16) = 180
Now we can simplify this equation:
7X - 16 = 180
7X = 196 (add 16 to both sides)
X = 196/7
X = 28
Therefore, the smallest angle is 28 degrees.
And from here we can figure out the other angles as they are 3x28 and 3x28 - 16.
So the three angles are 28 degrees, (3x28-16) 68 degrees, and (3x28) 84 degrees.

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?
Answer:
2 4/36
Step-by-step explanation:
To do this, multiply the whole number by the denominator and add it to the numerator.
8 x 9 = 72
72 + 4 = 76
76/9
Then multiply across (multiply numerators with numerators; denominators with denominators)
76 x 1 = 76
9 x 4 = 36
76/36 = 2 4/36
____________________________
A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.
1/4 x 8/1 = 8/4 = 2
1/4 x 4/9 = 4/36
= 2 4/36
Answer:
2 1/9
Step-by-step explanation:
Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.
1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)
1/4 x 76/9= 76/36
=38/18
=19/9
=2 1/9

Solve for x. 12(x+11) = 24
Answer:
x = -9
Step-by-step explanation:
First, divide both sides by 12 to isolate the expression, x + 11
12(x + 11)/12 = 24/12
x + 11 = 2
Then, subtract 11 from both sides
x + 11 = 2
- 11 - 11
x = -9

Step-by-step explanation:
As we are told, we need 3 sticks of butter for every 24 cookies. We can make this simple by figuring out how many cookies we can make with one stick of butter.
To do this is easy: 24 divded by 3 = 8
So 8 cookies per stick of butter
16 cookies would be 2 sticks of butter (as 8 x 2 is 16, and there's 8 cookies per butter stick)
and with 5 sticks of butter, we do (5 x 8 ) which equals 40

There are 52 weeks in a year. if Mr.Dan runs 9 miles every week, how many miles will he run in a year
Answer:
468 miles
Step-by-step explanation:
You have to multiply 52 by 9 and you get 468
Step-by-step explanation:
9 miles every week. and that for 52 weeks.
how do we calculate how many miles that are ?
well, one basic approach is
9 miles
9 miles
9 miles
... 52 times adding 9 miles.
in math we have a shortcut for that : we multiply. the hint is already in the "times" expression. we take 9 miles 52 times.
9 × 52 = 468 miles

Answer:
No, it's not because 6 x 4 = 24 and 2 x 3 = 6.
Step-by-step explanation:
In order for it to be equivalent, the simplified ratio needs to be multiplied by the same number, meaning because 6 x 4 = 24, the next number needs to be the product of 2 x 4, not 2 x 3.
Answer:
24:6 is equivalent to 6:2 because 6 times 4 is 24 and 2 times 3 is 6

Step-by-step explanation:
-4(-2x + 5) + 2x + 3 =-11
Distribute
8x-20 +2x+3 = -11
Combine like terms
10x-17 = -11
Add 17 to each side
10x-17+17 = -11+17
10x =6
Divide by 10
10x/10 = 6/10
x = 3/5

Answer:
58
Step-by-step explanation:
To find the range, you need to subtract the highest number from the lowest number.
So, the answer would be 58.
88-30=58
Answer:
Range=88°−30°=58°F
Step-by-step explanation:
The Range is the difference between the highest and the lowest values.
It tells us how far apart or how how widely spread the values are.
Range=88°−30°=58°F
In this month of July, all the values are within 58 ° of each other.
