Olivia can use 2 tens = 20 and 5 ones = 5 that equals 25 or she can use 25 ones = 25
Answer:
The answer is c
Step-by-step explanation:
5 x (2x7 ) 14 x 5 = 70
Answer:
y = 1
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
Where c is the value of the y- coordinates the line passes through.
The line passes through (- 4, 1 ) and (2, 1) with y- coordinates of 1
Thus the equation of the line is y = 1
Answer:
B,C,D
Step-by-step explanation:
B.
(15/3)^x can be simplified to 5^x because 15/3 = 5 and the power remains same after we simplify
C.

after rewriting the expression we can simplify 3^x from bottom and top so only 5^x remains.
D.
to multiply an exponential number you can add up their powers if their bases are same.
