Answer:
<ABC = 54 degrees
Step-by-step explanation:
Taking the sum of angle on the straight line ABD as 180 degrees
3x+9 + 9x - 9 =180
12x = 180
x = 180/12
x = 15 degrees
Since <ABC = 3x+9 (vertically opposite angles)
<ABC = 3(15)+9
<ABC = 45+9
<ABC = 54 degrees
Which number could not be value of x
A.8
B.9
C.12
D.21
Gupty travelled 75 km 800 m by car and travelled 1800 km 40 m by aeroplane.How much did she travel altogether?
Answer: 1875km 840m
Step-by-step explanation:
From the question, we are informed that Gupty travelled 75km 800m by car and travelled 1800km 40m by aeroplane.
The distance that she travel altogether will then be:
= 75km 800m + 1800km 40m
= 1875km 840m

A leather coat originally cost 125.99 and is on sale for 25% off. What is the new price of the leather coat
Answer: $94.49
Step-by-step explanation:
125.99 x 25/100
125.99 x 0.25
you save = $31.50
final price = original price - discount
final price = 125.99 - 31.4975
final price = $94.49

The ratio of blue skittles to red skittles in Tayler's bag is 3 to 4. If there are 20 red
skittles in Tayler's bag, how many total skittles does Tayler have? *
HELPPP ASAPPP PLEASE
Answer:
Tayler has 35 SHKITTLES IN ALL
Step-by-step explanation:
Since Tayler has 20 red Skittles, and the ratio of blue skittles to red skittles is 3 to 4, that means that Tayler has 3/4 as many blue skittles as she does red skittles. 3/4 of 20 is 15
20 + 15 = 35
Thus, Tayler has 35 skittles
SHKITTLES lol

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Your answer would be 189
Step-by-step explanation:
if you break the figure in to smaller parts you get for the two triangles 12*9/2. There are two of them, so that gets you 12*9/2+12*9/2, and all that equals 108. Finally, there is one more square in the middle, which equals 81, so 108+81=189, which is your answer.

I need help quick- Thanks btw :>
Answer: 3/4 feet
Step-by-step explanation:Conversion a mixed number 3 5/
12
to a improper fraction: 3 5/12 = 3 5/
12
= 3 · 12 + 5/
12
= 36 + 5/
12
= 41/
12
To find new numerator:
a) Multiply the whole number 3 by the denominator 12. Whole number 3 equally 3 * 12/
12
= 36/
12
b) Add the answer from previous step 36 to the numerator 5. New numerator is 36 + 5 = 41
c) Write a previous answer (new numerator 41) over the denominator 12.
Three and five twelfths is forty-one twelfths
Conversion a mixed number 2 2/
3
to a improper fraction: 2 2/3 = 2 2/
3
= 2 · 3 + 2/
3
= 6 + 2/
3
= 8/
3
To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/
3
= 6/
3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Subtract: 41/
12
- 8/
3
= 41/
12
- 8 · 4/
3 · 4
= 41/
12
- 32/
12
= 41 - 32/
12
= 9/
12
= 3 · 3/
3 · 4
= 3/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(12, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 3 = 36. In the next intermediate step , cancel by a common factor of 3 gives 3/

I FOUND THIS FUN BUT I DONT KNOW IF ITS RIGHT
^Solve for x. Please help me if you can I really need the answer
Answer:
x ≈ 25.1
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )
x × sin26° = 11 ( divide both sides by sin26° )
x = [tex]\frac{11}{sin26}[/tex] ≈ 25.1 ( to 1 dec. place )
"Correct" Answer:
53
Step-by-step explanation:
It's automadically 90 degrees because it's an acute angle, so you add 11 + 26 which gives you 37. Subtract 90 from 37 and it gives you 53, the variable.
26 + 11 = 37
90 - 37 = 53
