Answer:
20
Step-by-step explanation:
10 is equal to the side infront of it. 10 +10 = 20
rounding it to the nearest degree will also be 20
Answer:
B 2 2/3
Step-by-step explanation:
Triangles ADB and CDB are similar. Therefore similar parts can form a proportion.
AD/DB = DB/DC
AD = ?
DB = 4
DC = 6
x/4 = 4/6 Cross multiply
6x = 16
6x/6 = 16/6
x = 2 4/6 or x = 2 2/3
It's B
Answer:
116 = 116.
Step-by-step explanation:
Because the equations are the same, x + 4, they will always be equal to each other. 4 + 112 = 116.
If this helped I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
Lets x is the amount of money Paul spent
y is the amount of money John spent
<span>Henry spent 3 times as much as paul = 3x
so
</span>John and paul spent $45 altogether: <span>x + y = 45
</span> john and henty spent $65 altogether: 3x+y = 65
solve the equations
3x+y = 65
x + y = 45
---------------subtract
2x = 20
x = 10
x + y = 45
y = 45 - x
y = 45 - 10
y = 35
3x = 3(10) = 30
so
Paul spent $10 (x)
John spent $ 35 (y)
Henry spent $30 (3x)
answer: John spent $ 35
double check:
$ 35 + $ 10 = $45 (<span>John and Paul spent $45 altogether)
</span>$ 35 + $30 = $65 (<span> John and Henry spent $65 altogether)</span>
