Answer:
70 degrees
Step-by-step explanation:
2x+3x-20+x+20=180
( angles in a triangle add up to 180 degrees)
as you want to find one x you need to move everything else to the other side: first collect all the like terms: 6x=180
in order to find x you need to divide 180 by 6 which is equal to 30
therefore x=30
if you substitute this into XYZ it would be: 3(30)-20
90-20=70
therefore XYZ=70 degrees
Hope this helped
Answer:
70
Step-by-step explanation:
So we know that the angles of a triangle equal up to 180 degrees. So let's make an equation. So we can do:
2x+(3x-20)+(x+20) = 180
Simplify:
6x=180
x=30
We can also plug this in to check our work. So it would be:
60+(90-20)+(30+20)
simplify
70+50+60=180
Then we have to find angle XYZ so we do 90-20=70

The height of a stack of DVD cases is in a proportional relationship to the number of cases in the stack. A stack of 7 cases and its height are shown. Find the constant of proportionality. Then use the constant of proportionality to find the height of a stack of 12 cases.
Answers
Answer:
For a stack of 12 DVD cases, it will be 132mm in height
Step-by-step explanation:
There are 7 cases stacked on top of each other and the total height is 77mm.
Since you must find the height of each individual DVD case you have to divide the height (77mm) by the number of DVD cases (7):
77 / 7 = 11 or 77 ÷ 7 = 11
Then, it asks to find the height of a stack of 12 cases, so take the 11, the height of each DVD case, and multiply it by 12:
11 × 12 = 132
So, the height of 12 DVD cases stacked on top of each other is 132mm.

Answers
The sum of angles in a triangle is always equal to 180 degrees
Add:
65 + 51 + x + 73 = 180
x + 189 = 180
x = -9 That is fine that x is "-9" because this would just mean that the angle "x+73" is just bigger than it is supposed to be.
Proof:
65 + 51 - 9 + 73 = 180
Therefore, x = -9
Answer:
x = -9
Step-by-step explanation:
Notes to remember:
A triangle's angles will always add up to 180°
--------------------------------------------------------------------
As the image shows, we have two labeled angles. A 51° angle and a 65° angle.
Here's how you want to set up your equation:
180° = 51 + 65 + x + 73
(Rearrange)
180° = 51 + 65 + 73 + x
Add 51, 65, and 73
180° = 189 + x
Subtract 189 from both sides, to isolate x.
-9° = x
ALWAYS PLUG IN (the number that comes from the variable) TO CHECK YOUR WORK!
180° = 51 + 65 - 9 + 73

Answers
Answer:
5 + -2= 3
Step-by-step explanation:
the answer is 3 because you have to make zero pairs. the 2 negatives and 2 of the positives make a zero pair, which makes 3 positive ones left so the final answer is 3
Three is the sum because 5 is the highest number & is a positive. Therefore you keep the positive & subtract as normal. Making the answer 3.

Answers
Step-by-step explanation:
first derive a formula from that expression
y=kx
in this case k its a constant so we will find a constant first in order to derive a formula
substitute the variables with numbers been given
5=k(8) then make k subject of the formula
k=58 then make a formula from the constant
y= 58x
now this is your direct linear equation y= 58x
then use that equation in order to find the x value
finding x value, substitute the formula with the value given in this case y=15
then
y= 58x
15= 0.625x
150.625=x
24=x
therefore x =24
15= 0.625x
150.625=x
24=x

Answers
Answer: Antonio and Josue have 40 tickets left
Step-by-step explanation:
2 x ( 3 x 15 ) + ( 2 x 10 )
3 x 15 = 45
2 x 10 = 20
2 x 45 = 90
90 + 20 = 110
150 tickets is what they started with and they used 110 tickets 150 - 110 equals 40
It should be 110
2 x ( 3 x 15 ) + ( 2 x 10 )
3 x 15 = 45
2 x 10 = 20
2 x 45 = 90
90 + 20 = 110
110 = 40

Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run? Explain
Answers
Answer:
6 miles
Step-by-step explanation:
A mile is 1760 yards; and hour is 3600 (=2x1800) seconds.
So a yard per second is roughly two miles per hour (actually 1800/1760 x2 miles per hour, so the error is about 40 in 1800 or less than 1 in 40, 2.5%) and three yards per second is about 6 miles per hour. Upper bound of the estimate would be 6 + 2.5% = 6+0.15 = 6.15 mph.
