Step-by-step explanation:
Answer: C=40
Step-by-step explanation: X=40 APPLES PER BOX.
PROOF:
2+.25*40=12
2+10=12
12=12
Answer:
20
Step-by-step explanation:
3x+50 = 6x-10( opposite angles are equal)
3x = 60
x = 20
Natural numbers are 1,2,3 and so on. 13th and 23rd natural numbers are 13 an 23. Half the positive difference between 13th and 23rd natural numbers = (23-13)/2 = 5.
34th even natural number = 68
When half the positive difference between 13th and 23rd natural number added to 34th even natural number, result will be = 5+68 = 73.
Answer:
10a = 30
Step-by-step explanation:
By using elimination:
4a + 2z = 10
-2(3a + z) = -2(-10)
4a + 2z = 10
6a - 2z = 20
2z and -2z cancel out
10a = 30
a = 3
They are asking for 10a, so 10 (3) = 30.
