Answer:
The 3 angles are 62 2/3, 44 2/.3 and 72 2/3 degrees.
Step-by-step explanation:
let x be the first angle then the the second angle is x - 18 and the third angle = x + 10
The 3 angles add up to 180 so:
x + x - 18 + x + 10 = 180
3x = 180 + 18 - 10 = 188
x = 188/3 = 62 2/3 degrees.
x - 18 = 44 2/3
x + 10 = 72 2/3.
Answer:
17
Step-by-step explanation:
n = 17
n - 7 = 10
Carry over the - 7
n = 7 + 10
n = 17
Answer:
6
Step-by-step explanation:
Think of it as a ratio. The recipe calls for 2:3. If Jason used 4, then you need to match the other side.
4/2=2
So you need to multiply 3 by 2 to find the match.
3x2=6
The ratio is 4:6, so Jason uses 6 teaspoons of baking powder.

Answer:
100
Step-by-step explanation:
Based on the histogram given :
The vertical axis gives the number of student in the school :
For the range :
0 - 5 = 40
5 - 10 = 30
10 - 15 = 20
15 - 20 = 5
20 - 25 = 3
25 - 30 = 2
Taking the sum :
(40 + 30 + 20 + 5 + 3 + 2) = 100
Answer:x= 25
Step-by-step explanation:
504.2x + 29,165.8 is the number to divided by x.
