83 would be the answer. You don’t gotta multiply or anything
Answer:
No; equation
Step-by-step explanation:
2x+5 = 10 is not an expression rather it's an equation because it has an equal sign. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.
Answer:
a) 17
b) 45
Step-by-step explanation:
a)
use pemdas first,
= 4
3x4 = 12
1x4 = 4
now the equation is 
9+12 = 21
that makes the equation 21-4
21-4 = 17
a) 17
now for b
b)
the equation would then be 
so youd use pemdas as always
start in the parenthases
= 4
4-1 = 3
the equation is now 
now, multiply 3x3x4
3x3 = 9
9x4 = 36
now the equation is 9+36
9+36 is 45
b) 45
hope this helped!
Answer:
Step-by-step explanation:
The previous solar eclipse occured on March 7 , 1970 .
saros cycle has duration of 18 years , 11 + 1/3 days
So the earth goes 1 / 3 of its daily rotation beyond its previous location in the next solar eclipse on the earth . In order that we get solar eclipse on the same point on the earth , we shall have to wait for third solar eclipse
So total period of wait = 18 x 3 years + 11 x 3 + 1 = 54 years and 34 days
Date of next solar eclipse on the same spot = 1970 + 54 = 2024
7 th March + 34 days = April 10
likely date = April 10 , 2024 .
The answer is probably the first or second one. I made it easier for you
